We present grain-size-sorted quartz δ18O values in topsoil at 24 sites across the Eurasian steppe, from Ukraine and Kazakhstan to Xinjiang, Mongolia, and Inner Mongolia. Quartz fractions were separated from four fine soil classes (<2, 2–10, 10–20, 20–50 μm) at all sites, with additional coarse classes (50–200, 200–500, 500–2000 μm) at lithologically distinct locations. Coarse quartz grains in the Mongolian–Inner Mongolian Highlands show a relatively low and narrow δ18O range (7.6–9.0‰) over plutonic bedrocks and more variable higher values (8.9–17.8‰) over sedimentary bedrocks, indicating dependence on local lithology. In contrast, fine quartz grains (2–50 μm) exhibit a δ18O trend independent of bedrock lithology, indicating the values of regionally homogenized dust components. The δ18O values of the finest quartz fractions, exhibiting the highest at each site, decreased from the Western Steppe Plain (19.0 ± 0.8‰) through the Central Upland Steppe (18.0 ± 0.7‰) to the Mongolian–Inner Mongolian Highlands (13.8 ± 1.0‰), reflecting the distal dust input. Comparison with published quartz δ18O values for Mongolian and Northern China deserts and East Asian soils suggests that variable mixtures of these steppe end-members with Gobi and northern Chinese desert sources, along different atmospheric pathways of the East Asian winter monsoon, mid-latitude westerlies, and subtropical jets, can explain the aerosol-sized quartz in Japan and Korea. en-copyright= kn-copyright= en-aut-name=TeniGeer en-aut-sei=Teni en-aut-mei=Geer kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsanoMaki en-aut-sei=Asano en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TamuraKenji en-aut-sei=Tamura en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Science and Technology, University of Tsukuba kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Life and Environmental Sciences, University of Tsukuba kn-affil= affil-num=4 en-affil=Faculty of Life and Environmental Sciences, University of Tsukuba kn-affil= en-keyword=Aeolian dust kn-keyword=Aeolian dust en-keyword=Asian steppe kn-keyword=Asian steppe en-keyword=Oxygen isotopes kn-keyword=Oxygen isotopes en-keyword=Quartz kn-keyword=Quartz en-keyword=Japanese soil kn-keyword=Japanese soil en-keyword=Dust transport kn-keyword=Dust transport END start-ver=1.4 cd-journal=joma no-vol=361 cd-vols= no-issue= article-no= start-page=114818 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Far-red-enriched ultra-long-day conditions induce constitutive FT expression and rapid flowering in radish rootstocks, promoting graft-mediated floral induction in Brassicaceae crops en-subtitle= kn-subtitle= en-abstract= kn-abstract=Efficient floral induction is essential for breeding and seed production in Brassicaceae crops, particularly for late-bolting cultivars and plant-vernalization–type species such as cabbage (Brassica oleracea L.), which require substantial time and labor for artificial flower induction. A graft-mediated floral induction method was recently developed for cabbage, enabling flowering without vernalization treatment by grafting cabbage scions onto radish (Raphanus sativus L.) rootstocks. Although high expression of florigen gene FLOWERING LOCUS T (FT) in the rootstocks is a key determinant of success, environmental conditions capable of inducing strong FT expression in radish have remained unclear. Here, we demonstrate that a far-red-enriched ultra-long-day photoperiod (ULD-FR) markedly upregulates expression of radish FT homolog RsFTa and greatly enhances graft-mediated floral induction in cabbage. Under the ULD-FR condition, RsFTa expression remained constitutively high throughout the day, with daily transcript abundance increasing more than tenfold compared with standard high red/far-red (R/FR) ratio long-day conditions that employed fluorescent lamps. FT protein accumulation in cabbage scions grafted onto radish rootstocks was also strongly elevated, resulting in rapid flowering approximately 30 days after grafting. ULD-FR also promoted flowering in rapid-cycling Brassica rapa and B. oleracea accessions, and induced flowering in a vernalization-requiring R. sativus cultivar without low temperature treatment, suggesting that the response may be broadly conserved across Brassicaceae. Because ULD-FR can be implemented using standard lighting equipment by adding an FR light source, it presents potential utility as a versatile tool for breeding-related applications, including generation advancement and flowering synchronization among divergent accessions. en-copyright= kn-copyright= en-aut-name=MotokiKo en-aut-sei=Motoki en-aut-mei=Ko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KakitaNami en-aut-sei=Kakita en-aut-mei=Nami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=School of agriculture, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= en-keyword=FLOWERING LOCUS T (FT) kn-keyword=FLOWERING LOCUS T (FT) en-keyword=Florigen kn-keyword=Florigen en-keyword=Red/far-red ratio kn-keyword=Red/far-red ratio en-keyword=Graft-mediated floral induction kn-keyword=Graft-mediated floral induction en-keyword=Radish (Raphanus sativus) kn-keyword=Radish (Raphanus sativus) en-keyword=Cabbage (Brassica oleracea) kn-keyword=Cabbage (Brassica oleracea) en-keyword=Brassica rapa kn-keyword=Brassica rapa END start-ver=1.4 cd-journal=joma no-vol=367 cd-vols= no-issue= article-no= start-page=199714 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Virome of the fungi associated with mushroom dry bubble disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dry bubble disease, attributed to the filamentous fungus Lecanicillium fungicola (Cordycipitaceae) results in huge yield losses in mushroom (Agaricus bisporus) cultivation worldwide. The possibilities for controlling the disease using commercial fungicides are highly limited, and therefore, there is an increasing demand for novel, alternative means of pest management. Our research objective was the comprehensive examination of viruses in the causal agents of dry bubble disease, which may open up an avenue for its virocontrol in the future. Out of 57 fungal isolates obtained from dry bubble-affected A. bisporus crops in various countries, 47 (82%) were confirmed by ITS (Internal Transcribed Spacer) sequence analysis as L. fungicola. In addition, different members of the genera Akanthomyces and Simplicillium (7 and 3 isolates, respectively), yet unknown to cause dry bubble symptoms, have also been detected. Cellulose column chromatography revealed the presence of double-stranded (ds) RNA in seven L. fungicola and three Akanthomyces sp. isolates, suggesting viral infection. The ten dsRNA-positive and eight randomly selected dsRNA-negative fungal strains were subjected to rRNA-depletion high-throughput RNA-sequencing analysis. The presence of seven new viruses representing four new species in the established families, Partitiviridae, Polymycoviridae, Botourmiaviridae and the narna-like virus group, and three previously established/proposed species in the families Chrysoviridae and “Mycovirgaviridae” were confirmed. The impact of the detected and identified viruses on their host fungi, and their potential applicability for virocontrol purposes will be examined in the future. This study provides the first detailed report on viruses of mushroom pathogenic fungi. en-copyright= kn-copyright= en-aut-name=HatvaniLóránt en-aut-sei=Hatvani en-aut-mei=Lóránt kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugaharaHitomi en-aut-sei=Sugahara en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShahiSabitree en-aut-sei=Shahi en-aut-mei=Sabitree kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbiangSarah Remi en-aut-sei=Ibiang en-aut-mei=Sarah Remi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KocsubéSándor en-aut-sei=Kocsubé en-aut-mei=Sándor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KartaliTünde en-aut-sei=Kartali en-aut-mei=Tünde kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FitzpatrickDavid A. en-aut-sei=Fitzpatrick en-aut-mei=David A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=GroganHelen en-aut-sei=Grogan en-aut-mei=Helen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged kn-affil= affil-num=9 en-affil=Department of Biotechnology and Microbiology, Faculty of Science and Informatics, University of Szeged kn-affil= affil-num=10 en-affil=Genome Evolution Laboratory, Department of Biology, Maynooth University kn-affil= affil-num=11 en-affil=Teagasc Food Research Center, Horticulture Development Department kn-affil= affil-num=12 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Lecanicillium fungicola kn-keyword=Lecanicillium fungicola en-keyword=Agaricus bisporus kn-keyword=Agaricus bisporus en-keyword=Akanthomyces kn-keyword=Akanthomyces en-keyword=Simplicillium kn-keyword=Simplicillium en-keyword=dsRNA kn-keyword=dsRNA en-keyword=Myovirus kn-keyword=Myovirus en-keyword=Fungal virus kn-keyword=Fungal virus en-keyword=Mycovirgaviridae kn-keyword=Mycovirgaviridae en-keyword=Partitiviridae kn-keyword=Partitiviridae en-keyword=Polymycoviridae kn-keyword=Polymycoviridae en-keyword=Botourmiaviridae kn-keyword=Botourmiaviridae en-keyword=Splipalmiviridae kn-keyword=Splipalmiviridae en-keyword=Narna-like virus kn-keyword=Narna-like virus END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suppression of salt-enhanced apoplastic flow by salicylic acid in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Salinity enhances apoplastic flow, resulting in an increment of Na+ uptake and a lower K+/Na+ ratio. Salicylic acid (SA) plays an important role in improving salinity tolerance in plants. The effect of exogenous SA on apoplastic flow in salt-treated rice seedlings was studied using an apoplastic tracer, 8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS) in light. Application of NaCl at 25 mM to the hydroponic solution significantly increased PTS uptake, while 25 mM NaCl did not affect seedling growth. Application of 25 mM NaNO3 increased PTS uptake to the same degree. Salinity significantly increased sodium (Na+) content but had no significant effect on potassium (K+) content, resulting in a lower K+/Na+ ratio. The application of SA at 0.05 mM and 0.1 mM to the hydroponic solution reduced Na-enhanced PTS uptake. Salicylic acid at 0.05 mM and 0.1 mM significantly reduced Na+ content and slightly increased K+ content in the shoots of rice seedlings, resulting in a higher K+/Na+ ratio. However, SA at up to 0.1 mM did not increase SA contents in shoots under salt stress. These results suggest that exogenous SA reduces Na+ uptake by suppressing Na+-enhanced apoplastic flow in rice seedlings. These findings provide insight into modulation of Na+ transport pathways from roots to shoots by SA and may allow us to utilize brackish water for rice cultivation and to improve salt-tolerant rice through suppression of salt-enhanced apoplastic flow by chemicals such as salicylic acid. en-copyright= kn-copyright= en-aut-name=GalibMd.

Although recent research on teaching critical reading has been conducted, there have been criticisms that lack of consideration of content value and understanding context within society. There are also calls for critical reading that focuses on the perspective of “reflect” . Therefore, this paper developed a lesson that encourages students not only critically read the text, but also critically consider (reflect on) their own ideas. As a measure to achieve this, incorporated activities such as comparing two teaching materials that contained multiple social perceptions, exchanging opinions from opposing perspectives, writing an evaluation of the materials, and having the students themselves evaluate their own writing (their own reading). Analysis of the students’ writings shows that, while some students didn’ t reach conscious reflection, about 60% of students’ writings showed changes. And then it suggests that the methods used were effective. kn-abstract=　批判的読みは，現代では欠かせない能力であり，学習指導要領にも明記されている。近年，批判的読みの指導に関する研究がなされているものの，内容的な価値の検討や社会的な文脈のなかで捉えることが希薄だとする指摘や，「反省性」という観点に着目した批判的読みを求める声もある。そこで，本稿では，文章そのものを批判的に読むだけでなく，自身の持っている考えをも批判的に捉える（内省する）ことを促す授業を開発した。その手立てとして，複数の社会認識が存在する二つの教材の読み比べたうえで，対立する立場からの意見交換を行うことや，教材に対する評価の記述，その記述（自己の読み）を学習者自身が評価するといった活動を取り入れた。学習者の記述の分析からは，意識的な内省に至らなかった学習者も見受けられたものの，約６割の学習者の記述には変容が見られ，用いた手立ては効果があったと推測できることを指摘した。 en-copyright= kn-copyright= en-aut-name=SAISHOYumi en-aut-sei=SAISHO en-aut-mei=Yumi kn-aut-name=最相有未 kn-aut-sei=最相 kn-aut-mei=有未 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=反省性 (reflectiveness) kn-keyword=反省性 (reflectiveness) en-keyword=情意的性向 (affective disposition) kn-keyword=情意的性向 (affective disposition) en-keyword=複数テクスト (multiple texts) kn-keyword=複数テクスト (multiple texts) en-keyword=「現代の国語」 (“Contemporary Japanese Language”) kn-keyword=「現代の国語」 (“Contemporary Japanese Language”) en-keyword=生物多様性 (biodiversity) kn-keyword=生物多様性 (biodiversity) END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=8840 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=20260317 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tribolium castaneum with longer duration of tonic immobility have more variations corresponding to the human Parkinson’s disease genomic region en-subtitle= kn-subtitle= en-abstract= kn-abstract=Parkinson’s disease (PD) is a common neurodegenerative syndrome characterized by the loss of dopaminergic neurons and is also a progressive neurodegenerative disorder that is characterized by dopamine deficiency. We established strains artificially selected for longer and shorter durations of tonic immobility, an antipredator behavior that has received much attention recently, in the red flour beetle, Tribolium castaneum, a model insect species for molecular analyses different from Drosophila melanogaster. Previous studies have shown that the long strains (L-strain) have significantly lower levels of dopamine expression in the brain than the short strains (S-strain) and that they have an abnormal pattern of locomotor activity. Furthermore, previous studies have shown that administering dopamine to L-strain beetles reduces the duration of tonic immobility. Transcriptome analysis of brain and thorax of the L- and S-strains also showed differences in mRNA expression of genes involved in dopamine synthesis and tyrosine metabolism. These results indicate that the phenotype and molecular basis of the L-strain are similar to those of Parkinson’s syndrome symptoms. In order to establish a link between T. castaneum and PD, we compared the DNA sequences of the L- and S-strains to human genes affecting dopaminergic pathways. The DNA comparison revealed many mutated regions in these genes in the L-strain. We discuss the relationship between dopaminergic pathway genes and PD-like phenotypes across humans, Drosophila, and the red flour beetle. en-copyright= kn-copyright= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiKen en-aut-sei=Sasaki en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YajimaShunsuke en-aut-sei=Yajima en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Tamagawa University kn-affil= affil-num=3 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=4 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=50 article-no= start-page=e06926 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen Signaling via DDR1 Exacerbates Barriers to Macromolecular Drug Delivery in a 3D Model of Pancreatic Cancer Fibrosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fibrosis is a significant barrier to drug delivery in pancreatic ductal adenocarcinoma (PDAC) and contributes to its dismal prognosis. Pancreatic stellate cells (PSCs) drive fibrosis by excessively secreting extracellular matrix proteins such as collagen I. Collagen I is thought to physically obstruct the delivery of macromolecules, such as albumin, antibodies, and nanomedicines. Apart from its structural role, collagen signals through dedicated cell surface receptors, such as the discoidin domain receptors (DDR) 1/2. However, whether and how collagen signaling contributes to fibrotic barrier generation remains uncharacterized. Here, a 3D culture model of PDAC fibrosis constructed from patient PSCs is used to assess the contribution of DDR1/2-mediated collagen signaling. DDR1/2 inhibition diminishes collagen I expression in PSCs to enhance macromolecular delivery. Moreover, MEK inhibitors exacerbate the fibrotic barrier by up-regulating collagen I, an effect reversed by inhibiting DDR1/2. Through isoform-specific targeting, inhibiting DDR1, but not DDR2, is shown to be effective. Downstream of DDR, the involvement of the PI3K/AKT/mTOR pathway is demonstrated, particularly alternative mTOR complexes involving MEAK7 and GIT1. Altogether, the results show in vitro that DDR1-mediated collagen signaling exacerbates the fibrotic barrier and may be targeted to enhance macromolecular drug delivery in PDAC. en-copyright=

protein cpHsc70-1 interacts with thylakoid membrane remodeling protein VIPP1 C-terminal tail and controls VIPP1 oligomer assembly en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oxygenic photosynthetic organisms depend on the thylakoid membranes (TMs) for light-driven energy conversion. Recent studies on TM homeostasis (thylakostasis) have highlighted the essential role of the TM remodeling protein vesicle-inducing protein in plastid 1 (VIPP1). As a member of the endosomal sorting complexes required for transport-III (ESCRT-III)/phage shock protein A (PspA)/VIPP1 superfamily, VIPP1 forms large ring- and filament-like homo-oligomeric structures that exhibit a membrane remodeling activity. The oligomerization status was proposed to be modulated by the intrinsically disordered C-terminal tail (Vc), whereas its functional role remained unclear. Notably, this Vc region is conserved not only in photosynthetic VIPP1 but also in the PspA proteins of extremophilic species, implicating its role in membrane stress responses. To investigate the role of the Vc region in VIPP1 assembly, we performed coimmunoprecipitation assays in Arabidopsis chloroplasts and identified chloroplast-localized HSP70 proteins (cpHsc70) as major interactors. Among the two isoforms, cpHsc70-1 was found to be specifically required for modulating VIPP1 oligomeric assembly and dynamics in response to heat stress. Genetic analyses revealed that cpHsc70-1 facilitates the disassembly of VIPP1 oligomers, similarly to Vps4 ATPase in ESCRT-III; loss of either the Vc region or cpHsc70-1-impaired VIPP1 disassembly, resulting in more static oligomeric structures. Furthermore, cpHsc70-1 exhibited a broader role in chloroplast proteostasis, as the cphsc70-1 mutant showed impaired accumulation of green fluorescent protein (GFP)-fusion proteins. Together, our findings uncover a crucial crosstalk between proteostasis and thylakostasis in chloroplasts, coordinated by cpHsc70-1 and VIPP1 in response to membrane stress. en-copyright= kn-copyright= en-aut-name=LiDi en-aut-sei=Li en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GachieSarah Wanjiru en-aut-sei=Gachie en-aut-mei=Sarah Wanjiru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OzawaShin-ichiro en-aut-sei=Ozawa en-aut-mei=Shin-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ScholzMartin en-aut-sei=Scholz en-aut-mei=Martin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HipplerMichael en-aut-sei=Hippler en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Biology and Biotechnology, University of Münster kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=chloroplast kn-keyword=chloroplast en-keyword=heat shock protein kn-keyword=heat shock protein en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=thylakoid membrane remodeling kn-keyword=thylakoid membrane remodeling END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=1 article-no= start-page=100731 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2026 dt-pub=202602 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Insights into the taste of organic acids via TAS1Rs en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Organic acids contribute significantly to the flavor of fermented foods by imparting sourness. Although mice generally avoid sour taste, previous studies have reported greater consumption of l-lactic acid than its d-enantiomer, suggesting enantiomer-specific recognition. This behavior is hypothesized to involve TAS1Rs, which consists of sweet/umami receptors. However, it remains unclear whether TAS1Rs additionally contribute to the recognition of other chiral organic acids. This study aimed to evaluate the role of TAS1Rs, particularly TAS1R3, in the modulation of enantiomer-dependent behavioral responses to organic acids in mice.
Methods: Behavioral responses were evaluated using 48-h and 1-h 2-bottle tests. Binding of organic acids to TAS1Rs was investigated by differential scanning fluorimetry (DSF) with the ligand-binding domain (LBD) of medaka Tas1r2a/Tas1r3.
Results: Wild-type mice consumed more d-malic acid than l-malic acid in the 48-h test, whereas Tas1r3-KO mice showed no such difference. This pattern was not observed in the short-term 1-h test, which minimized the contribution of post-ingestion and learned effects. DSF analysis revealed no binding of any of the tested organic acids to the LBD of medaka Tas1r2a/Tas1r3.
Conclusions: Organic acids may elicit TAS1R3-dependent post-ingestion signals that contribute to enantiomer-selective consumption in mice. Electrostatic interactions and hydrogen-bonding networks within the orthosteric pocket of TAS1Rs may account for the differences in binding affinity to the LBD of medaka Tas1r2a/Tas1r3 between organic acids and L-alanine, a known ligand. en-copyright= kn-copyright= en-aut-name=YamaseYuko en-aut-sei=Yamase en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakebeKatsuki en-aut-sei=Takebe en-aut-mei=Katsuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HorieKengo en-aut-sei=Horie en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitohYoshihiro en-aut-sei=Mitoh en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaAtsuko en-aut-sei=Yamashita en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaRyusuke en-aut-sei=Yoshida en-aut-mei=Ryusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Institute for Protein Research, The University of Osaka kn-affil= affil-num=6 en-affil=Department of Oral Physiology, Graduate School of Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Taste detection kn-keyword=Taste detection en-keyword=Organic acid preference kn-keyword=Organic acid preference en-keyword=G-protein coupled receptor (GPCR) kn-keyword=G-protein coupled receptor (GPCR) en-keyword=Knockout mice kn-keyword=Knockout mice en-keyword=Surface electrostatic potential kn-keyword=Surface electrostatic potential END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suppression of Na+ Uptake Via Apoplastic Flow by Chitosan in Rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Chitosan enhances tolerance to salinity in rice. Apoplastic flow plays a crucial role in the accumulation of sodium (Na+) in rice under salinity. This study investigated the effects of exogenous chitosan on apoplastic flow and Na+ uptake in NaCl-treated rice seedlings. Methods: We employed an apoplastic tracer, trisodium salt of 8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS), in order to evaluate apoplastic flow in rice (Oryza sativa L., cv. Nipponbare) seedlings that were hydroponically grown in the solution containing NaCl (0 and 25 mM), and chitosan (0 mg L− 1, 10 mg L− 1, and 50 mg L− 1). Results: Application of 25 mM NaCl significantly increased PTS uptake and Na+ content in shoots but did not affect K+ content, resulting in a lower K+/Na+ ratio although 25 mM NaCl did not affect the seedling growth. The application of chitosan suppressed Na+-enhanced PTS uptake and Na+ accumulation in shoots without affecting the K+ content, which led to a higher K+/Na+ ratio. Moreover, chitosan did not affect the reducing sugar content or electrical conductivity in the solution containing NaCl. Conclusions: These results suggest that application of chitosan suppressed Na+-enhanced apoplastic flow to reduce Na+ uptake in rice seedlings. en-copyright= kn-copyright= en-aut-name=ZhaoMaoxiang en-aut-sei=Zhao en-aut-mei=Maoxiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GalibMd.

Non-invasive evaluations of AGB, including deep-learning-based red-green-blue (RGB) image analyses, are often specific to the training data. The robustness of the estimation model across untrained conditions is essential to monitor crop productivity globally, but it has yet to be fully assessed. This study aims to assess the robustness of a convolutional neural network (CNN) model for rice AGB estimation across five locations in three countries, and to demonstrate the feasibility of robust model via a practical approach. From transplanting to heading, 1957 RGB images were captured vertically downward over the rice canopy, covering approximately 1 m2. First, a base model was established using data collected from a single location. Then, its robustness was assessed using test datasets taken from the other four locations. The CNN model showed a significant variation in estimation accuracy across the untrained four locations, indicating insufficient robustness of the base model. Subsequently, we quantitatively tested the impact of improving training data diversity on model robustness by adding data from each of the four locations to the base model's training data. Adding at most 48 data points from a location achieved practical accuracy for the added location, with R2Ad above 0.8. Interestingly, adding data from one location sometimes improved the accuracy for other untrained locations as well. These findings suggest that collecting diverse training data for RGB-based estimation, combined with evaluation of robustness paves the way for on-site and instant AGB monitoring of rice. en-copyright= kn-copyright= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MochizukiAtsushi en-aut-sei=Mochizuki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaguchiTomoaki en-aut-sei=Yamaguchi en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AndrianaryBruce Haja en-aut-sei=Andrianary en-aut-mei=Bruce Haja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=International Rice Research Institute (IRRI) kn-affil= affil-num=3 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=CHIBA Prefectural Agriculture and Forestry Research Center kn-affil= affil-num=6 en-affil=Faculty of Applied Biological Sciences, Gifu University kn-affil= affil-num=7 en-affil= Africa Rice Center (AfricaRice), Regional Station for the Sahel kn-affil= affil-num=8 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=9 en-affil=Laboratoire des Radioisotopes, Université d′Antananarivo kn-affil= affil-num=10 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=11 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Robustness kn-keyword=Robustness en-keyword=RGB image kn-keyword=RGB image en-keyword=Rice, Above-ground biomass kn-keyword=Rice, Above-ground biomass en-keyword=Convolutional neural network kn-keyword=Convolutional neural network END start-ver=1.4 cd-journal=joma no-vol=187 cd-vols= no-issue= article-no= start-page=106403 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202508 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nitrogen distribution and nitrogen isotope fractionation in synthetic 2:1 phyllosilicates under hydrothermal conditions at 200 °C and saturated vapor pressure en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study investigates nitrogen distribution and isotope fractionation within synthetic 2:1 phyllosilicates, simulating submarine hydrothermal environments at 200 °C and saturated vapor pressure. XRD and EDS results revealed the potential coexistence of multiple cations in the interlayer of synthetic 2:1 phyllosilicate, concurrently suggesting cation substitution in the tetrahedral and/or octahedral sheets. Meanwhile, the iron-enriched 25-5 sample exhibited restricted interlayer expansibility. NH4+ absorptions were identified in the NH4-stretching (3200–2800 cm−1) and NH4-bending (1450–1400 cm−1) regions, with wavenumber shifts indicating the influence of interlayer water removal. At pH 10.56, over 95% of nitrogen was released into the gas phase, while at pH 8.88, nitrogen proportions in the liquid and gas phases were comparable (average 48–49%). Experiments with iron at pH ∼8.80 showed that the nitrogen proportion in the gas phase (average 28%) was more than twofold lower than that in the liquid phase (average 68%). Equilibrium isotope fractionation factors indicated discernible preference for heavier nitrogen isotopes in the solid phase (αsolid-liquid = 1.009–1.021 and αsolid-gas = 1.011–1.027). The αliquid-gas range for sample 25–2 was 1.001–1.008, while that for the iron-enriched composite 25–5 was 0.997–1.010. Our experimental studies have confirmed that, in the absence of exchange interactions with external substances possessing different nitrogen isotope ratios, nitrogen isotope fractionation between ammonium and ammonia, controlled by variations in temperature and pH during mineralization, plays a crucial role in the variation of nitrogen isotope ratios. Additionally, we confirmed that metal-amines influence nitrogen isotope fractionation by modulating ammonia gas emission. These findings enhance our understanding of nitrogen cycling across the gas, liquid, and solid phases in submarine hydrothermal systems. en-copyright= kn-copyright= en-aut-name=JoJaeguk en-aut-sei=Jo en-aut-mei=Jaeguk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanakaToshiro en-aut-sei=Yamanaka en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiYouko en-aut-sei=Miyoshi en-aut-mei=Youko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiMasaya en-aut-sei=Suzuki en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuwaharaYoshihiro en-aut-sei=Kuwahara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ChibaHitoshi en-aut-sei=Chiba en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=LeeBum Han en-aut-sei=Lee en-aut-mei=Bum Han kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=4 en-affil=Research Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= affil-num=5 en-affil=Department of Environmental Changes, Faculty of Social and Cultural Studies, Kyushu University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Critical Minerals Research Center, Korea Institute of Geoscience & Mineral Resources (KIGAM) kn-affil= en-keyword=Synthetic 2:1 phyllosilicates kn-keyword=Synthetic 2:1 phyllosilicates en-keyword=Nitrogen distribution kn-keyword=Nitrogen distribution en-keyword=Nitrogen isotope fractionation kn-keyword=Nitrogen isotope fractionation en-keyword=Hydrothermal system kn-keyword=Hydrothermal system END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=ycaf192 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proliferation of a bloom-forming phytoplankton via uptake of polyphosphate-accumulating bacteria under phosphate-limiting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Harmful algal blooms negatively impact the ecosystem and fisheries in affected areas. Eutrophication is a major factor contributing to bloom occurrence, and phosphorus is particularly important in limiting the growth of bloom-forming algae. Although algae efficiently utilize orthophosphate (Pi) as a phosphorous source over other molecular forms, Pi is often limited in the marine environment. While uptake and utilization of soluble inorganic and organic phosphorous by bloom-forming algae has been extensively studied, the details of geochemical and biological phosphorous cycling remain to be elucidated. Here, we report for the first time that the bloom-forming alga Heterosigma akashiwo can phagocytose bacteria and grow under phosphate-depleted conditions. The addition of Vibrio comitans to Pi-depleted H. akashiwo enabled the alga propagate to high cell densities, whereas other bacterial strains had only a minor effect. Importantly, V. comitans accumulates polyphosphate—a linear polymer of Pi—at high levels. The extent of algal proliferation induced by the addition of Vibrio species and polyphosphate-accumulating Escherichia coli correlated strongly with their polyphosphate content, indicating that bacterial polyphosphate served as an alternative PO43− source for H. akashiwo. The direct uptake of polyphosphate-accumulating bacteria through algal phagocytosis may represent a novel biological phosphorous-cycling pathway in marine ecosystems. The role of polyphosphate-accumulating marine bacteria as a hidden phosphorous source required for bloom formation warrants further investigation. en-copyright= kn-copyright= en-aut-name=FukuyamaSeiya en-aut-sei=Fukuyama en-aut-mei=Seiya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UsamiFumiko en-aut-sei=Usami en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirotaRyuichi en-aut-sei=Hirota en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OharaShizuka en-aut-sei=Ohara en-aut-mei=Shizuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoKen en-aut-sei=Kondo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=GomibuchiYuki en-aut-sei=Gomibuchi en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YasunagaTakuo en-aut-sei=Yasunaga en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OndukaToshimitsu en-aut-sei=Onduka en-aut-mei=Toshimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KurodaAkio en-aut-sei=Kuroda en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoikeKazuhiko en-aut-sei=Koike en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=UekiShoko en-aut-sei=Ueki en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=6 en-affil=Research Institute of Environment, Agriculture and Fisheries , Osaka Prefecture kn-affil= affil-num=7 en-affil=Department of Physics and Information Technology, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=8 en-affil=Department of Physics and Information Technology, Faculty of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=9 en-affil=Hatsukaichi Branch, Fisheries Technology Institute , Fisheries Research and Education Agency kn-affil= affil-num=10 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=11 en-affil=Graduate School of Integrated Sciences for Life, Hiroshima University kn-affil= affil-num=12 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ベトナム中部エビ養殖池排水路における水質保全のための底質微生物燃料電池の改良 kn-title=Improving sediment microbial fuel cells for water quality control in shrimp pond drainages in Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NGUYEN TU UYEN en-aut-sei=NGUYEN TU UYEN en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=腫瘍周囲組織が口腔扁平上皮癌の生物学的性格に与える影響 kn-title=The Origin of Stroma Influences the Biological Characteristics of Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OMORIHaruka en-aut-sei=OMORI en-aut-mei=Haruka kn-aut-name=大森悠加 kn-aut-sei=大森 kn-aut-mei=悠加 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=11 article-no= start-page=1446 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Propofol-Encapsulated Liposomes and the Effect of Intranasal Administration on Bioavailability in Rabbits en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Objectives: Propofol is frequently used as an intravenous anesthetic and is rapidly metabolized. Therefore, if it could be administered non-invasively (e.g., orally) as premedication, it might hasten emergence from anesthesia, thereby improving patient safety. However, it undergoes extensive first-pass metabolism in the liver and intestines, limiting the route for premedication. We evaluated whether intranasal delivery of a propofol-encapsulated liposome solution improves systemic exposure and bioavailability in rabbits. Methods: A propofol-encapsulated liposome solution was administered to rabbits via the intravenous, oral, and intranasal routes. Blood propofol concentrations were measured for up to 60 min after administration and the area under the concentration–time curve (AUC0–60) and bioavailability of the propofol-encapsulated liposome solution were compared with those of the non-encapsulated propofol formulation. The differences were tested by two-way analysis of variance (ANOVA) with Šidák’s post hoc multiple-comparisons test and the Mann–Whitney test (α = 0.05). Results: The AUC0–60 for blood propofol concentrations after intravenous administration was significantly higher with the propofol-encapsulated liposome solution than with the non-encapsulated propofol formulation (3038.8 ± 661.5 vs. 1929.8 ± 58.2 ng·min/mL; p = 0.0286). By contrast, no increase in blood propofol concentrations was observed after oral administration, whereas intranasal administration increased blood propofol concentrations and yielded significantly higher bioavailability compared with the non-encapsulated propofol formulation (16.4 ± 7.3% vs. 2.0 ± 1.2%; p = 0.0286). Conclusions: The findings of the present study suggest that intranasal liposomal propofol increased systemic availability compared with a non-encapsulated formulation, supporting further evaluation as a candidate premedication approach for propofol. en-copyright= kn-copyright= en-aut-name=UjitaHitomi en-aut-sei=Ujita en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiguchiHitoshi en-aut-sei=Higuchi en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishiokaYukiko en-aut-sei=Nishioka en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyakeSaki en-aut-sei=Miyake en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoRiko en-aut-sei=Sato en-aut-mei=Riko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiTakuya en-aut-sei=Miyawaki en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Dental Anesthesiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Dental Anesthesiology and Special Care Dentistry, Okayama University Graduate of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=liposome kn-keyword=liposome en-keyword=propofol kn-keyword=propofol en-keyword=bioavailability kn-keyword=bioavailability en-keyword=intranasal administration kn-keyword=intranasal administration END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251020 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Coupling effects of biochar and sediment microbial fuel cells on CH4 and CO2 emissions from straw-amended paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose The independent incorporation of biochar and sediment microbial fuel cells (SMFCs) into paddy soil has been shown to reduce methane (CH4) emissions. However, the application of rice straw into paddy soil enhances the availability of labile carbon that stimulates methanogen growth, counteracting the mitigation effects of both methods. This study, therefore, aimed to investigate the effect of coupling biochar and SMFC on CH4 and CO2 emissions from straw-amended paddy soil.
Materials and methods Single chamber SMFC setups constructed using acrylic columns (height, 25 cm; inner diameter, 9 cm) with six treatments were established using soil amended with 0% (0BC), 1% (1BC), and 2% (2BC) biochar: with and without SMFC conditions. Stainless steel mesh (15 × 3 cm) and graphite felt (6 × 5 cm) were used as anode and cathode materials, respectively.
Results Cumulative emission of CH4 in the 0BC treatment with SMFC was 39% less than in that without SMFC. Biochar addition and SMFC operation together further reduced CH4 emission by 57% and 60% in 1BC and 2BC treatments, respectively, compared to that in the 0BC treatment without SMFC operation. The relative abundance of microbial communities indicated methane-oxidizing bacteria were enriched in the presence of biochar and hydrogenotrophic Methanoregula were suppressed by SMFC operation. This suggested that SMFC mainly inhibited CH4 production by outcompeting hydrogenotrophic archaea.
Conclusion The use of biochar made from leftover rice straw has an interactive effect on SMFC operation and both methods can be used to reduce CH4 emission from straw-amended paddy soil. en-copyright= kn-copyright= en-aut-name=BekeleAdhena Tesfau en-aut-sei=Bekele en-aut-mei=Adhena Tesfau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashiguchiAyumi en-aut-sei=Hashiguchi en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AkaoSatoshi en-aut-sei=Akao en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=7 en-affil=Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Electrogenesis kn-keyword=Electrogenesis en-keyword=Methane oxidation kn-keyword=Methane oxidation en-keyword=Pyrolysis kn-keyword=Pyrolysis en-keyword=Paddy field kn-keyword=Paddy field en-keyword=Methanogens kn-keyword=Methanogens END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251005 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial Selections for Life-History Traits Affect Effective Cumulative Temperature and Developmental Zero Point in Zeugoducus cucurbitae en-subtitle= kn-subtitle= en-abstract= kn-abstract=Effective cumulative temperature and developmental zero point are important indicators for estimating the timing of organism development and the area of distribution. These indicators are generally considered to have unique values for different species of organisms and are also important for predicting the distribution range of animals and plants, especially insect pests. These values generally are species-specific, but there is variation within populations in traits having a genetic component. However, there are no studies on what kind of selection pressure affects these indicator values. To address this issue, it would be worthwhile to compare these values using individuals of strains that have been artificially selected for life-history traits by rearing them at various temperatures and calculating these indicators from developmental days and temperatures. In the present study, eggs were taken from adults of strains with many generations of artificial selection on two life-history traits (age at reproduction and developmental period) of the melon fly, Zeugodacus cucurbitae, under constant temperature conditions. Eggs were reared at five different temperatures, and the effective cumulative temperatures and developmental zero points of the larval and developmental periods were compared. The results demonstrate that artificial selection on life-history traits in Z. cucurbitae induces evolutionary changes in both the effective cumulative temperature and the developmental zero point across successive generations. en-copyright= kn-copyright= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environment, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of General Systems Studies, Graduate School of Arts and Sciences, the University of Tokyo kn-affil= en-keyword=age at reproduction kn-keyword=age at reproduction en-keyword=development time kn-keyword=development time en-keyword=developmental period kn-keyword=developmental period en-keyword=larval period kn-keyword=larval period en-keyword=melon fly kn-keyword=melon fly en-keyword=Tephritidae kn-keyword=Tephritidae en-keyword=thermal biology kn-keyword=thermal biology en-keyword=trade-offs kn-keyword=trade-offs END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=5 article-no= start-page=234 end-page=249 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Biochar-amended Sediment Microbial Fuel Cells for Water Quality Improvement in Intensive and Extensive Pond Drainages in Central Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=The use of nutrient-rich feed in shrimp farming in Central Vietnam has led to high nitrogen (N) and phosphorus (P) contents in the pond sediment. The objectives of the study were to assess the effectiveness of biochar-sediment microbial fuel cells (BC-SMFCs) in suppressing P and N release from two types of sediment in intensive (Int) and extensive (Ext) pond drainages in Central Vietnam. Single chamber SMFCs were set up and operated under open or closed-circuit (no SMFC or SMFC) conditions. Coconut shell biochar (BC) was amended to sediments at 1%. For Int-sediment, total phosphorus (TP) release was reduced by no BC-SMFCs through co-precipitation with Fe. On the other hand, BC-SMFCs did not suppress TP release because P was released from BC and organic matter decomposition was enhanced in the sediment. Application of BC enhanced organic N mineralization in the sediment. Nitrification and denitrification occurred in the overlying water, reducing mineral N concentrations. For Ext-sediment, BC addition and SMFC conditions did not affect TP and total nitrogen (TN) release because of low initial organic matter content, and less reductive condition. Our study suggested that the effect of SMFCs was masked by BC which released more P from Int-sediment to the water. en-copyright= kn-copyright= en-aut-name=NguyenUyen Tu en-aut-sei=Nguyen en-aut-mei=Uyen Tu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PereraGamamada Liyanage Erandi Priyangika en-aut-sei=Perera en-aut-mei=Gamamada Liyanage Erandi Priyangika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LeHuu Tien en-aut-sei=Le en-aut-mei=Huu Tien kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Comprehensive Technical Solutions, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Education, Science and Technology Quang Tri Branch, Hue University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=biochar kn-keyword=biochar en-keyword=Central Vietnam kn-keyword=Central Vietnam en-keyword=electricity generation kn-keyword=electricity generation en-keyword=redox potential kn-keyword=redox potential en-keyword=shrimp farming kn-keyword=shrimp farming END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=46 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20251009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Highly efficient transgenesis mediated by Tip100 transposon system in medaka en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transgenesis mediated by transposon is an effective approach for introducing exogenous DNA into the nuclear genome and establishing stable transgenic strains that efficiently express genetic tools. Although the DNA transposon Tol2 is widely used for transgenesis in zebrafish, its endogenous transpositional activity can lead to unintended transgene mobilization, making it unsuitable for transgenesis in medaka (Oryzias latipes). Here, we demonstrated that the DNA transposon Tip100, originally identified in the common morning glory (Ipomoea purpurea), an ornamental plant, can serve as a useful tool for transgenesis in Japanese medaka. The GFP transgene cassette, when co-injected with Tip100 transposase mRNA, was expressed in significantly higher number of somatic cells in the injected fish. Furthermore, a transgene flanked by truncated recognition sequences (100 bp each) exhibited expression levels comparable to those of the original vector containing the full 2.2 kb recognition sequence. Injection of a transgene driven by a germline-specific promoter revealed that fish injected with Tip100 mRNA exhibited a significantly higher germline transmission rate (42/68; 62.7%) compared to those injected without the mRNA (13/62; 21.0%). We successfully established transgenic strains by outcrossing injected founders with GFP-positive germ cells (7/7; 100%) and demonstrated that the transgenes were randomly integrated into the medaka genome, generating 8-bp duplications at the insertional sites–an insertional signature of the hAT superfamily of transposons. Our findings indicate that the Tip100 system is a promising tool for generating stable transgenic strains that express various genetic tools in medaka and potentially other fish species. en-copyright= kn-copyright= en-aut-name=TanakaYoshitaka en-aut-sei=Tanaka en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SekiTakahide en-aut-sei=Seki en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoshinoAtsushi en-aut-sei=Hoshino en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Okayama University kn-affil= affil-num=2 en-affil=Department of Integrative Life Sciences, Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=3 en-affil=National Institute for Basic Biology kn-affil= affil-num=4 en-affil=Ushimado Marine Institute (UMI), Okayama University kn-affil= en-keyword=Fish kn-keyword=Fish en-keyword=Medaka kn-keyword=Medaka en-keyword=Morning glory kn-keyword=Morning glory en-keyword=Transgenic kn-keyword=Transgenic en-keyword=Transposon kn-keyword=Transposon END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=9 article-no= start-page=1117 end-page=1125 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240622 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Solid-state cultivation of multiple industrial strains of koji mold on different Thai unpolished rice cultivars: biotransformation of phenolic compounds and their effects on antioxidant activity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Colored rice is abundant in polyphenols, and koji molds have potential for biotransformation. This study aimed to produce Thai-colored rice koji to study its polyphenolic biotransformation. Four industrial koji mold strains: Aspergillus oryzae 6001, A. oryzae 6020, A. sojae 7009, and A. luchuensis 8035, were cultivated on unpolished Thai-colored rice (Riceberry and Sangyod), unpolished Thai white rice (RD43), and polished Japanese white rice (Koshihikari). We discovered that koji molds grew on all the rice varieties. Methanol extracts of all rice kojis exhibited an approximately 2-fold or greater increase in total phenolic content and DPPH antioxidant activity compared to those of steamed rice. Moreover, quercetin, quercetin-3-O-glucoside, isorhamnetin-3-O-glucoside, ferulic acid, caffeic acid, protocatechuic acid, vanillic acid, (+)-catechin, and (–)-epicatechin content increased in Riceberry and Sangyod koji samples. Consequently, Aspergillus solid-state cultivation on unpolished Thai-colored rice exhibited higher functionalization than the cultivation of unpolished Thai white rice and polished Japanese white rice. en-copyright= kn-copyright= en-aut-name=JitpakdeeJirayu en-aut-sei=Jitpakdee en-aut-mei=Jirayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaHideyuki en-aut-sei=Yamashita en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaTakuro en-aut-sei=Nakagawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NitodaTeruhiko en-aut-sei=Nitoda en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanzakiHiroshi en-aut-sei=Kanzaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Higuchi Matsunosuke Shoten Co., Ltd. kn-affil= affil-num=3 en-affil=Higuchi Matsunosuke Shoten Co., Ltd. kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=antioxidant activity kn-keyword=antioxidant activity en-keyword=koji mold kn-keyword=koji mold en-keyword=polyphenols kn-keyword=polyphenols en-keyword=solid-state fermentation kn-keyword=solid-state fermentation en-keyword=Thai colored rice kn-keyword=Thai colored rice END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=ycaf092 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Methanol chemoreceptor MtpA- and flagellin protein FliC-dependent methylotaxis contributes to the spatial colonization of PPFM in the phyllosphere en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pink-pigmented facultative methylotrophs (PPFMs) capable of growth on methanol are dominant and versatile phyllosphere bacteria that provide positive effects on plant growth through symbiosis.

Here, we show that Methylobacterium sp. strain OR01 inoculated onto red perilla seeds colonized across the entire plant surface in the phyllosphere concomitant with the plant growth. During its transmission, strain OR01 was found to be present on the entire leaf surface with a preference to sites around the periphery, vein, trichome, and stomata. We found that methanol-sensing chemoreceptor MtpA-dependent chemotaxis (methylotaxis; chemotaxis toward methanol) and flagellin protein FliC-dependent motility facilitated the bacterial entry into the stomatal cavity and their colonization in the phyllosphere. en-copyright= kn-copyright= en-aut-name=KatayamaShiori en-aut-sei=Katayama en-aut-mei=Shiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiraishiKosuke en-aut-sei=Shiraishi en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KajiKanae en-aut-sei=Kaji en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawabataKazuya en-aut-sei=Kawabata en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraNaoki en-aut-sei=Tamura en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YurimotoHiroya en-aut-sei=Yurimoto en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakaiYasuyoshi en-aut-sei=Sakai en-aut-mei=Yasuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=2 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=4 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=5 en-affil=Department of Anatomy and Histology, School of Medicine, Fukushima Medical University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=8 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= en-keyword=PPFM kn-keyword=PPFM en-keyword=methylotaxis kn-keyword=methylotaxis en-keyword=phyllosphere kn-keyword=phyllosphere en-keyword=fluorescenceimaging kn-keyword=fluorescenceimaging en-keyword=bacterialbehavior kn-keyword=bacterialbehavior en-keyword=plant-microbeinteraction kn-keyword=plant-microbeinteraction END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=10 article-no= start-page=146 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Duganella hordei sp. nov., Duganella caerulea sp. nov., and Duganella rhizosphaerae sp. nov., isolated from barley rhizosphere en-subtitle= kn-subtitle= en-abstract= kn-abstract=Duganella sp. strains R1T, R57T, and R64T, isolated from barley roots in Japan, are Gram-stain-negative, motile, rod-shaped bacteria. Duganella species abundantly colonized barley roots. Strains R1T, R57T, and R64T were capable of growth at 4 °C, suggesting adaptation to colonize winter barley roots. Strains R57T and R64T formed purple colonies, indicating violacein production, while strain R1T did not. Based on 16S rRNA gene sequence similarities, strains R1T, R57T, and R64T were most closely related to D. violaceipulchra HSC-15S17T (99.10%), D. vulcania FT81WT (99.45%), and D. violaceipulchra HSC-15S17T (99.86%), respectively. Their genome sizes ranged from 7.05 to 7.38 Mbp, and their genomic G+C contents were 64.2–64.7%. The average nucleotide identity and digital DNA–DNA hybridization values between R1T and D. violaceipulchra HSC-15S17T, R57T and D. vulcania FT81WT, R64T and D. violaceipulchra HSC-15S17T were 86.0% and 33.2%, 95.7% and 67.9%, and 92.7% and 52.6%, respectively. Their fatty acids were predominantly composed of C16:0, C17:0 cyclo, and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c). Based on their distinct genetic and phenotypic characteristics, and supported by chemotaxonomic analyses, we propose that strains R1T, R57T, and R64T represent novel species within the Duganella genus, for which the names Duganella hordei (type strain R1T = NBRC 115982 T = DSM 115069 T), Duganella caerulea (type strain R57T = NBRC 115983 T = DSM 115070 T), and Duganella rhizosphaerae (type strain R64T = NBRC 115984 T = DSM 115071 T) are proposed. en-copyright= kn-copyright= en-aut-name=KishiroKatsumoto en-aut-sei=Kishiro en-aut-mei=Katsumoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SahinNurettin en-aut-sei=Sahin en-aut-mei=Nurettin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaishoDaisuke en-aut-sei=Saisho en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamajiNaoki en-aut-sei=Yamaji en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaJun en-aut-sei=Yamashita en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakagawaTomoyuki en-aut-sei=Nakagawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Egitim Fakultesi, Mugla Sitki Kocman University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Applied Biological Sciences, Gifu University kn-affil= affil-num=8 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Barley kn-keyword=Barley en-keyword=Duganella kn-keyword=Duganella en-keyword=Novel species kn-keyword=Novel species en-keyword=Rhizosphere kn-keyword=Rhizosphere END start-ver=1.4 cd-journal=joma no-vol=198 cd-vols= no-issue=1 article-no= start-page=kiaf137 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The thylakoid membrane remodeling protein VIPP1 forms bundled oligomers in tobacco chloroplasts en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thylakoid membrane (TM) serves as the scaffold for oxygen-evolving photosynthesis, hosting the protein complexes responsible for the light reactions and ATP synthesis. Vesicle inducing protein in plastid 1 (VIPP1), a key protein in TM remodeling, has been recognized as essential for TM homeostasis. In vitro studies of cyanobacterial VIPP1 demonstrated its ability to form large homo-oligomers (2 MDa) manifesting as ring-like or filament-like assemblies associated with membranes. Similarly, VIPP1 in Chlamydomonas reinhardtii assembles into rods that encapsulate liposomes or into stacked spiral structures. However, the nature of VIPP1 assemblies in chloroplasts, particularly in Arabidopsis, remains uncharacterized. Here, we expressed Arabidopsis thaliana VIPP1 fused to GFP (AtVIPP1-GFP) in tobacco (Nicotiana tabacum) chloroplasts and performed transmission electron microscopy (TEM). A purified AtVIPP1-GFP fraction was enriched with long filamentous tubule-like structures. Detailed TEM observations of chloroplasts in fixed resin-embedded tissues identified VIPP1 assemblies in situ that appeared to colocalize with GFP fluorescence. Electron tomography demonstrated that the AtVIPP1 oligomers consisted of bundled filaments near membranes, some of which appeared connected to the TM or inner chloroplast envelope at their contact sites. The observed bundles were never detected in wild-type Arabidopsis but were observed in Arabidopsis vipp1 mutants expressing AtVIPP1-GFP. Taken together, we propose that the bundled filaments are the dominant AtVIPP1 oligomers that represent its static state in vivo. en-copyright= kn-copyright= en-aut-name=GachieSarah W en-aut-sei=Gachie en-aut-mei=Sarah W kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MuhireAlexandre en-aut-sei=Muhire en-aut-mei=Alexandre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=LiDi en-aut-sei=Li en-aut-mei=Di kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawamotoAkihiro en-aut-sei=Kawamoto en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Takeda-KamiyaNoriko en-aut-sei=Takeda-Kamiya en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoYumi en-aut-sei=Goto en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoMayuko en-aut-sei=Sato en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToyookaKiminori en-aut-sei=Toyooka en-aut-mei=Kiminori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshimuraRyo en-aut-sei=Yoshimura en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakamiTsuneaki en-aut-sei=Takami en-aut-mei=Tsuneaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ZhangLingang en-aut-sei=Zhang en-aut-mei=Lingang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KurisuGenji en-aut-sei=Kurisu en-aut-mei=Genji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TerachiToru en-aut-sei=Terachi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute for Protein Research, Osaka University kn-affil= affil-num=5 en-affil=Mass Spectrometry and Microscopy Unit, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=6 en-affil=Mass Spectrometry and Microscopy Unit, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=7 en-affil=Mass Spectrometry and Microscopy Unit, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=8 en-affil=Mass Spectrometry and Microscopy Unit, RIKEN Center for Sustainable Resource Science kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=11 en-affil=School of Life Sciences, Inner Mongolia University/Key Laboratory of Herbage and Endemic Crop Biotechnology kn-affil= affil-num=12 en-affil=Institute for Protein Research, Osaka University kn-affil= affil-num=13 en-affil=Faculty of Life Sciences, Kyoto Sangyo University kn-affil= affil-num=14 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=pcaf098 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250822 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thylakostasis: key factors in thylakoid membrane organization with emphasis on biogenesis and remodeling proteins in vascular plants en-subtitle= kn-subtitle= en-abstract= kn-abstract=The thylakoid membrane (TM), a defining feature for almost all oxygen-evolving photosynthetic organisms, serves as the structural foundation for light-driven energy conversion. In vascular plants, the TM evolved into a complex architecture composed of single-layered stroma thylakoids and stacked grana thylakoids, enabling the spatial organization of two photosystems (PSII and PSI) to optimize light capture and energy transfer. In addition, two membrane regions, one connecting these two compartments (grana margin) and the other corresponding to the curvature domain in grana, function in dissipating excess energy, balancing electron transfer, and maintaining functional PSII. Recent advances in electron microscopy imaging and proteome analysis of membrane subcompartments have provided new insights into the structure and dynamic adaptations of the TM in response to diverse environmental conditions. To describe the mechanisms that govern TM architecture, dynamics, and integrity, I am introducing the concept of “thylakostasis” (thylakoid homeostasis). Here, I provide an overview of the molecular components and processes central to thylakostasis, including the biosynthesis of lipids, chlorophyll, and proteins. I focus particularly on the membrane remodeling proteins whose functions have been elucidated recently, such as VIPP1, a member of the evolutionarily conserved PspA/ESCRT-III superfamily; FZL, a dynamin-like GTPase; and CURT1, a curvature-inducing protein unique to photosynthetic organisms. Together, these factors orchestrate TM biogenesis, remodeling, and adaptive flexibility that is essential for photosynthetic efficiency. en-copyright= kn-copyright= en-aut-name=SakamotoWataru en-aut-sei=Sakamoto en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=chloroplast kn-keyword=chloroplast en-keyword=ESCRT-III (endosomal sorting complex required for transport complex III) kn-keyword=ESCRT-III (endosomal sorting complex required for transport complex III) en-keyword=grana kn-keyword=grana en-keyword=membrane trafficking kn-keyword=membrane trafficking en-keyword=photosynthesis kn-keyword=photosynthesis en-keyword=stroma thylakoid kn-keyword=stroma thylakoid END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=wrae175 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cyanorhodopsin-II represents a yellow-absorbing proton-pumping rhodopsin clade within cyanobacteria en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microbial rhodopsins are prevalent in many cyanobacterial groups as a light-energy-harvesting system in addition to the photosynthetic system. It has been suggested that this dual system allows efficient capture of sunlight energy using complementary ranges of absorption wavelengths. However, the diversity of cyanobacterial rhodopsins, particularly in accumulated metagenomic data, remains underexplored. Here, we used a metagenomic mining approach, which led to the identification of a novel rhodopsin clade unique to cyanobacteria, cyanorhodopsin-II (CyR-II). CyR-IIs function as light-driven outward H+ pumps. CyR-IIs, together with previously identified cyanorhodopsins (CyRs) and cyanobacterial halorhodopsins (CyHRs), constitute cyanobacterial ion-pumping rhodopsins (CyipRs), a phylogenetically distinct family of rhodopsins. The CyR-II clade is further divided into two subclades, YCyR-II and GCyR-II, based on their specific absorption wavelength. YCyR-II absorbed yellow light (λmax = 570 nm), whereas GCyR-II absorbed green light (λmax = 550 nm). X-ray crystallography and mutational analysis revealed that the difference in absorption wavelengths is attributable to slight changes in the side chain structure near the retinal chromophore. The evolutionary trajectory of cyanobacterial rhodopsins suggests that the function and light-absorbing range of these rhodopsins have been adapted to a wide range of habitats with variable light and environmental conditions.

This study focuses on the tomato due to its economic importance and cultivation under moderate salinity conditions in Japan. A swelling assay using X. laevis oocyte confirmed that all five examined tomato SlPIP2 isoforms showed water transport activity. Among them, two-electrode voltage clamp (TEVC) experiments showed that only SlPIP2;1, SlPIP2;4, and SlPIP2;8 transport Na+ and K+, with no transport activity for Cs+, Rb+, Li+, or Cl−. CaCl2 (1.8 mM) reduced ionic currents by approximately 45% compared to 30 µM free-Ca2+. These isoforms function as very low-affinity Na+ and K+ transporters. Expression analysis showed that SlPIP2;4 and SlPIP2;8 had low, stable expression, while SlPIP2;1 was strongly upregulated in roots NaCl treatment (200 mM, 17days), suggesting distinct physiological roles for these ion-conducting AQPs (icAQPs). These data hypothesized that tomato icAQPs play a critical role in ion homeostasis, particularly under salinity stress. In conclusion, the first icAQPs have been identified in the dicotyledonous crop. These icAQPs are essential for plant resilience under salt stress. en-copyright= kn-copyright= en-aut-name=PaulNewton Chandra en-aut-sei=Paul en-aut-mei=Newton Chandra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImranShahin en-aut-sei=Imran en-aut-mei=Shahin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsumotoAnri en-aut-sei=Mitsumoto en-aut-mei=Anri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Aquaporin (AQP) kn-keyword=Aquaporin (AQP) en-keyword=ion transport kn-keyword=ion transport en-keyword=plasma membrane intrinsic proteins (PIPs) kn-keyword=plasma membrane intrinsic proteins (PIPs) en-keyword=tomato kn-keyword=tomato en-keyword=oocytes kn-keyword=oocytes en-keyword=water transport kn-keyword=water transport END start-ver=1.4 cd-journal=joma no-vol=89 cd-vols= no-issue=8 article-no= start-page=1217 end-page=1226 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250527 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microbial biotransformation of proteins into amino acids in unpolished Thai and polished Japanese rice varieties cultivated with distinct industrial strains of koji mold en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously reported the cultivation of industrial koji mold strains to produce unpolished Thai-colored rice kojis. These kojis, along with those made from unpolished Thai white rice and polished Japanese white rice, showed increased polyphenol content after cultivation, with the highest levels observed in unpolished Thai-colored rice kojis. In this study, an increase in both proteinogenic and non-proteinogenic amino acid contents, particularly γ-aminobutyric acid (GABA) content, was observed in both unpolished Thai and polished Japanese rice kojis, suggesting the ability of koji mold in the biotransformation of proteins. This increase was almost comparable even when using different rice varieties; in contrast, it varied depending on the koji mold strain used. The observed increase in both polyphenol and functional amino acid contents, especially GABA content, highlights the potential of unpolished Thai and polished Japanese rice kojis, particularly unpolished Thai-colored rice koji, as multifunctional materials, benefiting from polyphenol and amino acid functionalities. en-copyright= kn-copyright= en-aut-name=JitpakdeeJirayu en-aut-sei=Jitpakdee en-aut-mei=Jirayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ItoKazunari en-aut-sei=Ito en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaninoYuka en-aut-sei=Tanino en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiHayato en-aut-sei=Takeuchi en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamashitaHideyuki en-aut-sei=Yamashita en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagawaTakuro en-aut-sei=Nakagawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NitodaTeruhiko en-aut-sei=Nitoda en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanzakiHiroshi en-aut-sei=Kanzaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Industrial Technology Center of Okayama Prefecture kn-affil= affil-num=3 en-affil=Industrial Technology Center of Okayama Prefecture kn-affil= affil-num=4 en-affil=Industrial Technology Center of Okayama Prefecture kn-affil= affil-num=5 en-affil=Higuchi Matsunosuke Shoten Co., Ltd. kn-affil= affil-num=6 en-affil=Higuchi Matsunosuke Shoten Co., Ltd. kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Amino acid kn-keyword=Amino acid en-keyword=GABA kn-keyword=GABA en-keyword=koji mold kn-keyword=koji mold en-keyword=rice koji kn-keyword=rice koji en-keyword=Thai-colored rice kn-keyword=Thai-colored rice END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=2 article-no= start-page=606 end-page=617 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250130 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mechanistic Insights Into Oxidative Response of Heat Shock Factor 1 Condensates en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heat shock factor 1 (Hsf1), a hub protein in the stress response and cell fate decisions, senses the strength, type, and duration of stress to balance cell survival and death through an unknown mechanism. Recently, changes in the physical property of Hsf1 condensates due to persistent stress have been suggested to trigger apoptosis, highlighting the importance of biological phase separation and transition in cell fate decisions. In this study, the mechanism underlying Hsf1 droplet formation and oxidative response was investigated through 3D refractive index imaging of the internal architecture, corroborated by molecular dynamics simulations and biophysical/biochemical experiments. We found that, in response to oxidative conditions, Hsf1 formed liquid condensates that suppressed its internal mobility. Furthermore, these conditions triggered the hyper-oligomerization of Hsf1, mediated by disulfide bonds and secondary structure stabilization, leading to the formation of dense core particles in the Hsf1 droplet. Collectively, these data demonstrate how the physical property of Hsf1 condensates undergoes an oxidative transition by sensing redox conditions to potentially drive cell fate decisions. en-copyright= kn-copyright= en-aut-name=KawagoeSoichiro en-aut-sei=Kawagoe en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsusakiMotonori en-aut-sei=Matsusaki en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MabuchiTakuya en-aut-sei=Mabuchi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgasawaraYuto en-aut-sei=Ogasawara en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WatanabeKazunori en-aut-sei=Watanabe en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshimoriKoichiro en-aut-sei=Ishimori en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaioTomohide en-aut-sei=Saio en-aut-mei=Tomohide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=2 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= affil-num=3 en-affil=Frontier Research Institute for Interdisciplinary Sciences, Tohoku University kn-affil= affil-num=4 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=6 en-affil=Department of Chemistry, Faculty of Science, Hokkaido University kn-affil= affil-num=7 en-affil=Institute of Advanced Medical Sciences, Tokushima University kn-affil= en-keyword=heat shock factor 1 kn-keyword=heat shock factor 1 en-keyword=oxidative hyper-oligomerization kn-keyword=oxidative hyper-oligomerization en-keyword=biological phase transition kn-keyword=biological phase transition en-keyword=stress response kn-keyword=stress response en-keyword=biophysics kn-keyword=biophysics END start-ver=1.4 cd-journal=joma no-vol=219 cd-vols= no-issue= article-no= start-page=104944 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Establishment of a transgenic strain for the whole brain calcium imaging in larval medaka fish (Oryzias latipes) en-subtitle= kn-subtitle= en-abstract= kn-abstract=GCaMP-based calcium imaging is a powerful tool for investigating neural function in specific neurons.

Using these Tg larvae, calcium imaging successfully detected a tricaine-induced suppression of spontaneous neural activity and topographical visual responses in the optic tectum elicited by moving paramecia or optical fiber stimulation. These results indicate that our Tg medaka strains provide a versatile platform for investigating neural dynamics and their responses to various stimuli. en-copyright= kn-copyright= en-aut-name=SekiTakahide en-aut-sei=Seki en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyanariKazuhiro en-aut-sei=Miyanari en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiraishiAsuka en-aut-sei=Shiraishi en-aut-mei=Asuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsudaSachiko en-aut-sei=Tsuda en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AnsaiSatoshi en-aut-sei=Ansai en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakeuchiHideaki en-aut-sei=Takeuchi en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= affil-num=2 en-affil=Graduate School of Science and Engineering, Saitama University kn-affil= affil-num=3 en-affil=Graduate School of Science and Engineering, Saitama University kn-affil= affil-num=4 en-affil=Graduate School of Science and Engineering, Saitama University kn-affil= affil-num=5 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Life Sciences, Tohoku University kn-affil= en-keyword=gap43 kn-keyword=gap43 en-keyword=JGCaMP7s kn-keyword=JGCaMP7s en-keyword=Ac/Ds kn-keyword=Ac/Ds en-keyword=Visuotopy kn-keyword=Visuotopy en-keyword=slc2a15b kn-keyword=slc2a15b END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=12 article-no= start-page=4932 end-page=4951 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The leucine-rich repeat receptor kinase QSK1 regulates PRR-RBOHD complexes targeted by the bacterial effector HopF2Pto en-subtitle= kn-subtitle= en-abstract= kn-abstract=Plants detect pathogens using cell-surface pattern recognition receptors (PRRs) such as ELONGATION Factor-TU (EF-TU) RECEPTOR (EFR) and FLAGELLIN SENSING 2 (FLS2), which recognize bacterial EF-Tu and flagellin, respectively. These PRRs belong to the leucine-rich repeat receptor kinase (LRR-RK) family and activate the production of reactive oxygen species via the NADPH oxidase RESPIRATORY BURST OXIDASE HOMOLOG D (RBOHD). The PRR-RBOHD complex is tightly regulated to prevent unwarranted or exaggerated immune responses. However, certain pathogen effectors can subvert these regulatory mechanisms, thereby suppressing plant immunity. To elucidate the intricate dynamics of the PRR-RBOHD complex, we conducted a comparative coimmunoprecipitation analysis using EFR, FLS2, and RBOHD in Arabidopsis thaliana. We identified QIAN SHOU KINASE 1 (QSK1), an LRR-RK, as a PRR-RBOHD complex-associated protein. QSK1 downregulated FLS2 and EFR abundance, functioning as a negative regulator of PRR-triggered immunity (PTI). QSK1 was targeted by the bacterial effector HopF2Pto, a mono-ADP ribosyltransferase, reducing FLS2 and EFR levels through both transcriptional and transcription-independent pathways, thereby inhibiting PTI. Furthermore, HopF2Pto transcriptionally downregulated PROSCOOP genes encoding important stress-regulated phytocytokines and their receptor MALE DISCOVERER 1-INTERACTING RECEPTOR-LIKE KINASE 2. Importantly, HopF2Pto requires QSK1 for its accumulation and virulence functions within plants. In summary, our results provide insights into the mechanism by which HopF2Pto employs QSK1 to desensitize plants to pathogen attack. en-copyright= kn-copyright= en-aut-name=GotoYukihisa

Sediment Microbial Fuel Cells on CH4 and CO2 Emissions from Straw Amended Paddy Soil en-subtitle= kn-subtitle= en-abstract= kn-abstract=Straw returning into paddy soil enhances soil organic matter which usually promotes the emission of greenhouse gases to the atmosphere. The application of sediment microbial fuel cells (SMFCs) to paddy soil activates power-generating microorganisms and enhances organic matter biodegradation. In the present study, rice straw addition in SMFCs was examined to determine its effect on CH4 and CO2 emissions. Columns (height, 25 cm; inner diameter, 9 cm) with four treatments: soil without and with rice straw under SMFC and without SMFC conditions were incubated at 25°C for 70 days. Anodic potential values at 7 cm depth sediment were kept higher by SMFCs than those without SMFCs. Cumulative CH4 emission was significantly reduced by SMFC with straw amendment (p < 0.05) with no significant effect on CO2 emission. 16S rRNA gene analysis results showed that Firmicutes at the phylum, Closteridiales and Acidobacteriales at order level were dominant on the anode of straw-added SMFC, whereas Methanomicrobiales were in the treatment without SMFC, indicating that a certain group of methanogens were suppressed by SMFC. Our results suggest that the anodic redox environment together with the enrichment of straw-degrading bacteria contributed to a competitive advantage of electrogenesis over methanogenesis in straw-added SMFC system. en-copyright= kn-copyright= en-aut-name=BekeleAdhena Tesfau en-aut-sei=Bekele en-aut-mei=Adhena Tesfau kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkaoSatoshi en-aut-sei=Akao en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishinaYuta en-aut-sei=Nishina en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=straw kn-keyword=straw en-keyword=methane mitigation kn-keyword=methane mitigation en-keyword=SMFC kn-keyword=SMFC en-keyword=microorganisms kn-keyword=microorganisms en-keyword=current generation kn-keyword=current generation END start-ver=1.4 cd-journal=joma no-vol=351 cd-vols= no-issue= article-no= start-page=199522 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evidence for the replication of a plant rhabdovirus in its arthropod mite vector en-subtitle= kn-subtitle= en-abstract= kn-abstract=Transmission of plant viruses that replicate in the insect vector is known as persistent-propagative manner. However, it remains unclear whether such virus-vector relationships also occur between plant viruses and other biological vectors such as arthropod mites. In this study, we investigated the possible replication of orchid fleck virus (OFV), a segmented plant rhabdovirus, within its mite vector (Brevipalpus californicus s.l.) using quantitative RT-qPCR, western blotting and next-generation sequencing. Time-course RT-qPCR and western blot analyses showed an increasing OFV accumulation pattern in mites after virus acquisition. Since OFV genome expression requires the transcription of polyadenylated mRNAs, polyadenylated RNA fractions extracted from the viruliferous mite samples and OFV-infected plant leaves were used for RNA-seq analysis. In the mite and plant datasets, a large number of sequence reads were aligned to genomic regions of OFV RNA1 and RNA2 corresponding to transcribed viral gene mRNAs. This includes the short polyadenylated transcripts originating from the leader and trailer regions at the ends of the viral genome, which are believed to play a crucial role in viral transcription/replication. In contrast, a low number of reads were mapped to the non-transcribed regions (gene junctions). These results strongly suggested that OFV gene expression occurs both in mites and plants. Additionally, deep sequencing revealed the accumulation of OFV-derived small RNAs in mites, although their size profiles differ from those found in plants. Taken together, our results indicated that OFV replicates within a mite vector and is targeted by the RNA-silencing mechanism. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaMiki en-aut-sei=Fujita en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TelengechPaul en-aut-sei=Telengech en-aut-mei=Paul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MaruyamKazuyuki en-aut-sei=Maruyam en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HyodoKiwamu en-aut-sei=Hyodo en-aut-mei=Kiwamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TassiAline Daniele en-aut-sei=Tassi en-aut-mei=Aline Daniele kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OchoaRonald en-aut-sei=Ochoa en-aut-mei=Ronald kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=6 en-affil=Tropical Research and Education Center, University of Florida kn-affil= affil-num=7 en-affil=Systematic Entomology Laboratory, USDA kn-affil= affil-num=8 en-affil=College of Plant Protection, Northwest A&F University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= en-keyword=Rhabdovirus kn-keyword=Rhabdovirus en-keyword=Plant kn-keyword=Plant en-keyword=Mite kn-keyword=Mite en-keyword=Vector kn-keyword=Vector en-keyword=Replication kn-keyword=Replication en-keyword=mRNA kn-keyword=mRNA en-keyword=Small RNA kn-keyword=Small RNA END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Amino Acid Substitutions in Loop C of Arabidopsis PIP2 Aquaporins Alters the Permeability of CO2 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The transport of CO2 across biomembranes in plant cells is essential for efficient photosynthesis. Some aquaporins capable of CO2 transport, referred to as ‘COOporins’, are postulated to play a crucial role in leaf CO2 diffusion. However, the structural basis of CO2 permeation through aquaporins remains largely unknown. Here, we show that amino acids in loop C are critical for the CO2 permeability of Arabidopsis thaliana PIP2 aquaporins. We found that swapping tyrosine and serine in loop C to histidine and phenylalanine, which differ between AtPIP2;1 and AtPIP2;3, altered CO2 permeability when examined in the Xenopus laevis oocyte heterologous expression system. AlphaFold2 modelling indicated that these substitution induced a conformational shift in the sidechain of arginine in the aromatic/arginine (ar/R) selectivity filter and in lysine at the extracellular mouth of the monomeric pore in PIP2 aquaporins. Our findings demonstrate that distal amino acid substitutions can trigger conformational changes of the ar/R filter in the monomeric pore, modulating CO2 permeability. Additionally, phylogenetic analysis suggested that aquaporins capable of dual water/CO2 permeability are ancestral to those that are water-selective and CO2-impermeable, and CO2-selective and water impermeable. en-copyright= kn-copyright= en-aut-name=TaniaShaila Shermin en-aut-sei=Tania en-aut-mei=Shaila Shermin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UtsugiShigeko en-aut-sei=Utsugi en-aut-mei=Shigeko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsuchiyaYoshiyuki en-aut-sei=Tsuchiya en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasanoShizuka en-aut-sei=Sasano en-aut-mei=Shizuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuharaMaki en-aut-sei=Katsuhara en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=CO2 transport kn-keyword=CO2 transport en-keyword=monomeric pore kn-keyword=monomeric pore en-keyword=PIP2 aquaporin kn-keyword=PIP2 aquaporin en-keyword=Xenopus laevis kn-keyword=Xenopus laevis END start-ver=1.4 cd-journal=joma no-vol=177 cd-vols= no-issue=4 article-no= start-page=e70396 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CNGC2 Negatively Regulates Stomatal Closure and Is Not Required for flg22- and H2O2-Induced Guard Cell [Ca2+]cyt Elevation in Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=In guard cells, cytosolic Ca2+ acts as a second messenger that mediates abscisic acid (ABA)- and pathogen-associated molecular pattern (PAMP)-induced stomatal closure. It was reported that Arabidopsis cyclic nucleotide-gated ion channel 2 (CNGC2) functions as hydrogen peroxide (H2O2)- and PAMP-activated Ca2+-permeable channels at the plasma membrane of mesophyll cells and mediates Ca2+-dependent PAMP-triggered immunity. In this study, we examined the role of CNGC2 in the regulation of stomatal movement because CNGC2 is also expressed in guard cells. We found that stomata of the CNGC2 disruption mutant cngc2-3 are constitutively closed even in the absence of ABA or the flagellar-derived PAMP, flg22. Consistently, leaf temperatures of the cngc2-3 mutant were higher than those of wild-type (WT) plants. The stomatal phenotype of the cngc2-3 mutant was restored by complementation with wild-type CNGC2 under the control of the guard cell preferential promoter, pGC1. Elevation of cytosolic free Ca2+ concentration in guard cells induced by flg22 and H2O2 remained intact in the cngc2-3 mutant. The introduction of the ost1-3 mutation into the cngc2-3 background did not alter the stomatal phenotype. However, the stomatal phenotype of the cngc2-3 mutant was successfully rescued in the double disruption mutant cngc2-3aba2-2. Taken together, these results suggest that CNGC2 negatively regulates stomatal closure response and does not function as flg22– and H2O2-activated Ca2+ channels in guard cells. Though CNGC2 is responsive for H2O2- and flg22-induced [Ca2+]cyt elevation in mesophyll cells, the involvement of CNGC2 in the response to H2O2 and flg22 in guard cells is questionable. en-copyright= kn-copyright= en-aut-name=AkterRojina en-aut-sei=Akter en-aut-mei=Rojina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueYasuhiro en-aut-sei=Inoue en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasumotoSaori en-aut-sei=Masumoto en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MimataYoshiharu en-aut-sei=Mimata en-aut-mei=Yoshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil= kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=calcium signaling kn-keyword=calcium signaling en-keyword=CNGC kn-keyword=CNGC en-keyword=stomata kn-keyword=stomata END start-ver=1.4 cd-journal=joma no-vol=301 cd-vols= no-issue=7 article-no= start-page=110291 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202507 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A repertoire of visible light–sensitive opsins in the deep-sea hydrothermal vent shrimp Rimicaris hybisae en-subtitle= kn-subtitle= en-abstract= kn-abstract=Unlike terrestrial environments, where humans reside, there is no sunlight in the deep sea. Instead, dim visible light from black-body radiation and bioluminescence illuminates hydrothermal vent areas in the deep sea. A deep-sea hydrothermal vent shrimp, Rimicaris hybisae, is thought to detect this dim light using its enlarged dorsal eye; however, the molecular basis of its photoreception remains unexplored. Here, we characterized the molecular properties of opsins, universal photoreceptive proteins in animals, found in R. hybisae. Transcriptomic analysis identified six opsins: three Gq-coupled opsins, one Opn3, one Opn5, and one peropsin. Functional analysis revealed that five of these opsins exhibited light-dependent G protein activity, whereas peropsin exhibited the ability to convert all-trans-retinal to 11-cis-retinal like photoisomerases. Notably, all the R. hybisae opsins, including Opn5, convergently show visible light sensitivity (around 457–517 nm), whereas most opsins categorized as Opn5 have been demonstrated to be UV sensitive. Mutational analysis revealed that the unique visible light sensitivity of R. hybisae Opn5 is achieved through the stabilization of a protonated Schiff base by a counterion residue at position 83 (Asp83), which differs from the position identified in other opsins. These findings suggest that the vent shrimp R. hybisae has adapted its photoreceptive devices to dim deep-sea hydrothermal light by selectively maintaining a repertoire of visible light–sensitive opsins, including the uniquely tuned Opn5. en-copyright= kn-copyright= en-aut-name=NagataYuya en-aut-sei=Nagata en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoNorio en-aut-sei=Miyamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoKeita en-aut-sei=Sato en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraYosuke en-aut-sei=Nishimura en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaniokaYuki en-aut-sei=Tanioka en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamanakaYuji en-aut-sei=Yamanaka en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshizawaSusumu en-aut-sei=Yoshizawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakahashiKuto en-aut-sei=Takahashi en-aut-mei=Kuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ObayashiKohei en-aut-sei=Obayashi en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsukamotoHisao en-aut-sei=Tsukamoto en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaiKen en-aut-sei=Takai en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YamashitaTakahiro en-aut-sei=Yamashita en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SudoYuki en-aut-sei=Sudo en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Institute for Extra-Cutting-Edge Science and Technology Avant-Garde Research (X-Star), Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Research Center for Bioscience and Nanoscience (CeBN), Research Institute for Marine Resources Utilization, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=5 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=School of Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=8 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Biology, Graduate School of Science, Kobe University kn-affil= affil-num=10 en-affil=Department of Biology, Graduate School of Science, Kobe University kn-affil= affil-num=11 en-affil=Institute for Extra-Cutting-Edge Science and Technology Avant-Garde Research (X-Star), Japan Agency for Marine-Earth Science and Technology (JAMSTEC) kn-affil= affil-num=12 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=13 en-affil=Department of Biophysics, Graduate School of Science, Kyoto University kn-affil= affil-num=14 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=15 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=opsin kn-keyword=opsin en-keyword=G protein–coupled receptor kn-keyword=G protein–coupled receptor en-keyword=signal transduction kn-keyword=signal transduction en-keyword=photoreceptor kn-keyword=photoreceptor en-keyword=vision kn-keyword=vision en-keyword=photobiology kn-keyword=photobiology en-keyword=vent shrimp kn-keyword=vent shrimp en-keyword=deep sea kn-keyword=deep sea en-keyword=molecular evolution kn-keyword=molecular evolution END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sulfur dioxide-induced guard cell death and stomatal closure are attenuated in nitrate/proton antiporter AtCLCa mutants en-subtitle= kn-subtitle= en-abstract= kn-abstract=Guard cells surrounding the stomata play a crucial role in regulating the entrance of hazardous gases such as SO2 into leaves. Stomatal closure could be a plant response to mitigate SO2 damage, although the mechanism for SO2-induced closure remains controversial. Proposed mediators for SO2-induced stomatal closure include phytohormones, reactive oxygen species, gasotransmitters, and cytosolic acidification. In this study, we investigated the mechanism of stomatal closure in Arabidopsis in response to SO2. Despite an increment in auxin and jasmonates after SO2 exposure, the addition of auxin did not cause stomatal closure and jasmonate-insensitive mutants exhibited SO2-induced stomatal closure suggesting auxin and jasmonates are not mediators leading to the closure. In addition, supplementation of scavenging reagents for reactive oxygen species and gasotransmitters did not inhibit SO2-induced closure. Instead, we found that cytosolic acidification is a credible mechanism for SO2-induced stomatal closure in Arabidopsis. CLCa mutants coding H+/nitrate antiporter, involved in cytosolic pH homeostasis, showed less sensitive stomatal phenotype against SO2. These results suggest that cytosolic pH homeostasis plays a tenable role in SO2 response in guard cells. en-copyright= kn-copyright= en-aut-name=OoiLia en-aut-sei=Ooi en-aut-mei=Lia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=airborne pollutants kn-keyword=airborne pollutants en-keyword=cytosolic acidification kn-keyword=cytosolic acidification en-keyword=stomatal closure kn-keyword=stomatal closure en-keyword=sulfur dioxide kn-keyword=sulfur dioxide END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=稲わら施用水田土壌からのCH4およびCO2 排出抑制に向けた底質微生物燃料電池の開発 kn-title=Development of sediment microbial fuel cells to reduce CH4 and CO2 emissions from straw-amended paddy soil en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ADHENA TESFAU BEKELE en-aut-sei=ADHENA TESFAU BEKELE en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=生物学的製剤の使用は、関節リウマチに対する整形外科手術後の手術部位感染や創傷治癒遅延を増加させない kn-title=The use of biologic disease-modifying antirheumatic drugs does not increase surgical site infection or delayed wound healing after orthopaedic surgeries for rheumatoid arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KISOYohei en-aut-sei=KISO en-aut-mei=Yohei kn-aut-name=木曽洋平 kn-aut-sei=木曽 kn-aut-mei=洋平 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=４種類の醸造用麹菌による４種類の米の固体培養：ポリフェノール類とタンパク質の生物変換 kn-title=Aspergillus Solid-State Cultivation of Four Different Industrial Strains of Koji Mold on Four Different Rice Cultivars: Microbial Biotransformation of Phenolic Compounds and Proteins en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=JITPAKDEE JIRAYU en-aut-sei=JITPAKDEE JIRAYU en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=リボソーム・トランスロコン複合体の再局在化が、真核生物発生における小胞体出現の重要なイベントである証拠 kn-title=Evidence for the relocalization of the ribosome-translocon complex as a key event for the emergence of endoplasmic reticulum during eukaryogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=CARILOIsaac en-aut-sei=CARILO en-aut-mei=Isaac kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama university kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=10 article-no= start-page=1164 end-page=1171 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cytosolic acidification and oxidation are the toxic mechanisms of SO2 in Arabidopsis guard cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=SO2/H2SO3 can damage plants. However, its toxic mechanism has still been controversial. Two models have been proposed, cytosolic acidification model and cellular oxidation model. Here, we assessed the toxic mechanism of H2SO3 in three cell types of Arabidopsis thaliana, mesophyll cells, guard cells (GCs), and petal cells. The sensitivity of GCs of Chloride channel a (CLCa)-knockout mutants to H2SO3 was significantly lower than those of wildtype plants. Expression of other CLC genes in mesophyll cells and petal cells were different from GCs. Treatment with antioxidant, disodium 4,5-dihydroxy-1,3-benzenedisulfonate (tiron), increased the median lethal concentration (LC50) of H2SO3 in GCs indicating the involvement of cellular oxidation, while the effect was negligible in mesophyll cells and petal cells. These results indicate that there are two toxic mechanisms of SO2 to Arabidopsis cells: cytosolic acidification and cellular oxidation, and the toxic mechanism may vary among cell types. en-copyright=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dihydroxyacetone (DHA) occurs in wide-ranging organisms, including plants, and can undergo spontaneous conversion to methylglyoxal (MG). While the toxicity of MG to plants is well-known, the toxicity of DHA to plants remains to be elucidated. We investigated the effects of DHA and MG on Arabidopsis. Exogenous DHA at up to 10 mM did not affect the radicle emergence, the expansion of green cotyledons, the seedling growth, or the activity of glyoxalase II, while DHA at 10 mM inhibited the root elongation and increased the activity of glyoxalase I. Exogenous MG at 1.0 mM inhibited these physiological responses and increased both activities. Dihydroxyacetone at 10 mM increased the MG content in the roots. These results indicate that DHA is not so toxic as MG in Arabidopsis seeds and seedlings and suggest that the toxic effect of DHA at high concentrations is attributed to MG accumulation by the conversion to MG. en-copyright= kn-copyright= en-aut-name=ZhaoMaoxiang en-aut-sei=Zhao en-aut-mei=Maoxiang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraToshiyuki

kn-article= en-subject= kn-subject= en-title= kn-title=Hepatitis C virus NS5B triggers an MDA5-mediated innate immune response by producing dsRNA without the replication of viral genomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=During the replication of viral genomes, RNA viruses produce double-stranded RNA (dsRNA), through the activity of their RNA-dependent RNA polymerases (RdRps) as viral replication intermediates. Recognition of viral dsRNA by host pattern recognition receptors – such as retinoic acid-induced gene-I (RIG-I)-like receptors and Toll-like receptor 3 – triggers the production of interferon (IFN)-β via the activation of IFN regulatory factor (IRF)-3. It has been proposed that, during the replication of viral genomes, each of RIG-I and melanoma differentiation-associated gene 5 (MDA5) form homodimers for the efficient activation of a downstream signalling pathway in host cells. We previously reported that, in the non-neoplastic human hepatocyte line PH5CH8, the RdRp NS5B derived from hepatitis C virus (HCV) could induce IFN-β expression by its RdRp activity without the actual replication of viral genomes. However, the exact mechanism by which HCV NS5B produced IFN-β remained unknown. In the present study, we first showed that NS5B derived from another Flaviviridae family member, GB virus B (GBV-B), also possessed the ability to induce IFN-β in PH5CH8 cells. Similarly, HCV NS5B, but not its G317V mutant, which lacks RdRp activity, induced the dimerization of MDA5 and subsequently the activation of IRF-3. Interestingly, immunofluorescence analysis showed that HCV NS5B produced dsRNA. Like HCV NS5B, GBV-B NS5B also triggered the production of dsRNA and subsequently the dimerization of MDA5. Taken together, our results show that HCV NS5B triggers an MDA5-mediated innate immune response by producing dsRNA without the replication of viral genomes in human hepatocytes. en-copyright= kn-copyright= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AriumiYasuo en-aut-sei=Ariumi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TogashiYosuke en-aut-sei=Togashi en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Division of Biological Information Technology, Joint Research Center for Human Retrovirus Infection, Kagoshima University kn-affil= affil-num=3 en-affil=Management Department of Biosafety, Laboratory Animal, and Pathogen Bank, National Institute of Infectious Diseases kn-affil= affil-num=4 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Tumor Microenvironment, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=double-stranded RNA kn-keyword=double-stranded RNA en-keyword=hepatitis C virus kn-keyword=hepatitis C virus en-keyword=innate immunity kn-keyword=innate immunity en-keyword=RIG-I-like receptor kn-keyword=RIG-I-like receptor en-keyword=RNA virus kn-keyword=RNA virus END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=三環性融合ピリミジン類の合成と生物活性分子設計 kn-title=Synthesis and biological active molecular design of tricyclic fused pyrimidines en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Shoeb Ahmed en-aut-sei=Shoeb Ahmed en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=46 end-page=55 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Ancient DNA studies of human remains kn-title=生物遺骸に残された“DNA の記録” を読み解く en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MIZUNOFuzuki en-aut-sei=MIZUNO en-aut-mei=Fuzuki kn-aut-name=水野文月 kn-aut-sei=水野 kn-aut-mei=文月 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=東邦大学 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220922 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=じん肺患者における悪性新生物の標準化罹患比 kn-title=Standardized incidence ratios of malignant neoplasms among patients with pneumoconiosis en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MICHIBATATatsuya en-aut-sei=MICHIBATA en-aut-mei=Tatsuya kn-aut-name=道端達也 kn-aut-sei=道端 kn-aut-mei=達也 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=5 article-no= start-page=459 end-page=467 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Constant Light, Pdp1, and Tim Exert Influence on Free-Running Period of Locomotor Rhythms in the Cricket Gryllus bimaculatus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Most insects show circadian rhythms of which the free-running period changes in a light-dependent manner and is generally longer under constant light (LL) than under constant dark conditions in nocturnal animals. However, the mechanism underlying this LL-dependent period change remains unclear. Here, using the cricket Gryllus bimaculatus, we examined the effects of long-term LL exposure on the free-running period of locomotor rhythms. Initially, the free-running period was considerably longer than 24 h but it gradually became shorter during long-term exposure to LL. The initiallengthening and ensuing gradual shortening under long-term LL exposure were observed evenafter unilateral removal of the optic lobe. Thus, these changes in the free-running period could be attributable to a single optic lobe clock. RNA interference (RNAi)-mediated silencing of the clock genes Par domain protein 1 (Pdp1) and timeless (tim) revealed that the treatments eliminated the initial period lengthening by LL without reducing circadian photoreceptor gene expression. However, they did not affect the period shortening during long-term LL exposure. The slopes of the regression line for the period change during long-term LL for Pdp1RNAi-treated and timRNAi-treated crickets were not different from that of the dsDsRed2-treated control. These results suggest that the initial period lengthening after transfer to LL requires tim and Pdp1, while the ensuing period shortening during long-term LL exposure is caused by a mechanism independent of tim and Pdp1. en-copyright= kn-copyright= en-aut-name=MoriyamaYoshiyuki en-aut-sei=Moriyama en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiKazuki en-aut-sei=Takeuchi en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Natural Sciences, Kawasaki Medical School, Kurashiki 701-0192, Japan kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University, Okayama 700-8530, Japan kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University, Okayama 700-8530, Japan kn-affil= en-keyword=circadian rhythm kn-keyword=circadian rhythm en-keyword=cricket kn-keyword=cricket en-keyword=free-running period kn-keyword=free-running period en-keyword=constant light kn-keyword=constant light en-keyword=clock gene kn-keyword=clock gene END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=921635 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Siderophore for Lanthanide and Iron Uptake for Methylotrophy and Plant Growth Promotion in Methylobacterium aquaticum Strain 22A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylobacterium and Methylorubrum species are facultative methylotrophic bacteria that are abundant in the plant phyllosphere. They have two methanol dehydrogenases, MxaF and XoxF, which are dependent on either calcium or lanthanides (Lns), respectively. Lns exist as insoluble minerals in nature, and their solubilization and uptake require a siderophore-like substance (lanthanophore). Methylobacterium species have also been identified as plant growth-promoting bacteria although the actual mechanism has not been well-investigated. This study aimed to reveal the roles of siderophore in Methylobacterium aquaticum strain 22A in Ln uptake, bacterial physiology, and plant growth promotion. The strain 22A genome contains an eight-gene cluster encoding the staphyloferrin B-like (sbn) siderophore. We demonstrate that the sbn siderophore gene cluster is necessary for growth under low iron conditions and was complemented by supplementation with citrate or spent medium of the wild type or other strains of the genera. The siderophore exhibited adaptive features, including tolerance to oxidative and nitrosative stress, biofilm formation, and heavy metal sequestration. The contribution of the siderophore to plant growth was shown by the repressive growth of duckweed treated with siderophore mutant under iron-limited conditions; however, the siderophore was dispensable for strain 22A to colonize the phyllosphere. Importantly, the siderophore mutant could not grow on methanol, but the siderophore could solubilize insoluble Ln oxide, suggesting its critical role in methylotrophy. We also identified TonB-dependent receptors (TBDRs) for the siderophore-iron complex, iron citrate, and Ln, among 12 TBDRs in strain 22A. Analysis of the siderophore synthesis gene clusters and TBDR genes in Methylobacterium genomes revealed the existence of diverse types of siderophores and TBDRs. Methylorubrum species have an exclusive TBDR for Ln uptake that has been identified as LutH. Collectively, the results of this study provide insight into the importance of the sbn siderophore in Ln chelation, bacterial physiology, and the diversity of siderophore and TBDRs in Methylobacterium species. en-copyright= kn-copyright= en-aut-name=JumaPatrick Otieno en-aut-sei=Juma en-aut-mei=Patrick Otieno kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaniYoshiko en-aut-sei=Fujitani en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AlessaOla en-aut-sei=Alessa en-aut-mei=Ola kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OyamaTokitaka en-aut-sei=Oyama en-aut-mei=Tokitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YurimotoHiroya en-aut-sei=Yurimoto en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaiYasuyoshi en-aut-sei=Sakai en-aut-mei=Yasuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil= Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil= Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Science, Kyoto University kn-affil= affil-num=5 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Methylobacterium species kn-keyword=Methylobacterium species en-keyword=lanthanide kn-keyword=lanthanide en-keyword=lanthanophore kn-keyword=lanthanophore en-keyword=siderophore kn-keyword=siderophore en-keyword=plant growth promoter kn-keyword=plant growth promoter en-keyword=heavy metal sequestration kn-keyword=heavy metal sequestration END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=921636 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220623 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Periplasmic Lanthanide Mediator, Lanmodulin, in Methylobacterium aquaticum Strain 22A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylobacterium and Methylorubrum species oxidize methanol via pyrroloquinoline quinone-methanol dehydrogenases (MDHs). MDHs can be classified into two major groups, Ca2+-dependent MDH (MxaF) and lanthanide (Ln(3+))-dependent MDH (XoxF), whose expression is regulated by the availability of Ln(3+). A set of a siderophore, TonB-dependent receptor, and an ABC transporter that resembles the machinery for iron uptake is involved in the solubilization and transport of Ln(3+). The transport of Ln(3+) into the cytosol enhances XoxF expression. A unique protein named lanmodulin from Methylorubrum extorquens strain AM1 was identified as a specific Ln(3+)-binding protein, and its biological function was implicated to be an Ln(3+) shuttle in the periplasm. In contrast, it remains unclear how Ln(3+) levels in the cells are maintained, because Ln(3+) is potentially deleterious to cellular systems due to its strong affinity to phosphate ions. In this study, we investigated the function of a lanmodulin homolog in Methylobacterium aquaticum strain 22A. The expression of a gene encoding lanmodulin (lanM) was induced in response to the presence of La3+. A recombinant LanM underwent conformational change upon La3+ binding. Phenotypic analyses on lanM deletion mutant and overexpressing strains showed that LanM is not necessary for the wild-type and XoxF-dependent mutant's methylotrophic growth. We found that lanM expression was regulated by MxcQE (a two-component regulator for MxaF) and TonB_Ln (a TonB-dependent receptor for Ln(3+)). The expression level of mxcQE was altered to be negatively dependent on Ln(3+) concentration in increment lanM, whereas it was constant in the wild type. Furthermore, when exposed to La3+, increment lanM showed an aggregating phenotype, cell membrane impairment, La deposition in the periplasm evidenced by electron microscopy, differential expression of proteins involved in membrane integrity and phosphate starvation, and possibly lower La content in the membrane vesicle (MV) fractions. Taken together, we concluded that lanmodulin is involved in the complex regulation mechanism of MDHs and homeostasis of cellular Ln levels by facilitating transport and MV-mediated excretion. en-copyright= kn-copyright= en-aut-name=FujitaniYoshiko en-aut-sei=Fujitani en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShibataTakeshi en-aut-sei=Shibata en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=K.K.

Within these genera, however, some species lack either pigmentation or methylotrophy, which raises the question of what actually defines the PPFMs. The present study employed a comprehensive comparative genomics approach to reveal the phylogenetic relationship among the PPFMs and to explain the genotypic differences that confer their different phenotypes. We newly sequenced the genomes of 29 relevant-type strains to complete a dataset for almost all validly published species in the genera. Through comparative analysis, we revealed that methylotrophy, nitrate utilization, and anoxygenic photosynthesis are hallmarks differentiating the PPFMs from the other Methylobacteriaceae. The Methylobacterium species in clade A, including the type species Methylobacterium organophilum, were phylogenetically classified into six subclades, each possessing relatively high genomic homology and shared phenotypic characteristics. One of these subclades is phylogenetically close to Methylorubrum species; this finding led us to reunite the two genera into a single genus Methylobacterium. Clade C, meanwhile, is composed of phylogenetically distinct species that share relatively higher percent G+C content and larger genome sizes, including larger numbers of secondary metabolite clusters. Most species of clade C and some of clade A have the glutathione-dependent pathway for formaldehyde oxidation in addition to the H4MPT pathway. Some species cannot utilize methanol due to their lack of MxaF-type methanol dehydrogenase (MDH), but most harbor an XoxF-type MDH that enables growth on methanol in the presence of lanthanum. The genomes of PPFMs encode between two and seven (average 3.7) genes for pyrroloquinoline quinone-dependent alcohol dehydrogenases, and their phylogeny is distinctly correlated with their genomic phylogeny. All PPFMs were capable of synthesizing auxin and did not induce any immune response in rice cells. Other phenotypes including sugar utilization, antibiotic resistance, and antifungal activity correlated with their phylogenetic relationship. This study provides the first inclusive genotypic insight into the phylogeny and phenotypes of PPFMs. en-copyright= kn-copyright= en-aut-name=AlessaOla en-aut-sei=Alessa en-aut-mei=Ola kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OguraYoshitoshi en-aut-sei=Ogura en-aut-mei=Yoshitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujitaniYoshiko en-aut-sei=Fujitani en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakamiHideto en-aut-sei=Takami en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayashiTetsuya en-aut-sei=Hayashi en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SahinNurettin en-aut-sei=Sahin en-aut-mei=Nurettin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Atmosphere and Ocean Research Institute, The University of Tokyo kn-affil= affil-num=5 en-affil=Department of Bacteriology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=6 en-affil=Egitim Fakultesi, Mugla Sitki Kocman University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Methylobacterium kn-keyword=Methylobacterium en-keyword=comparative genomics kn-keyword=comparative genomics en-keyword=methylotroph kn-keyword=methylotroph en-keyword=methanol dehydrogenase kn-keyword=methanol dehydrogenase en-keyword=Methylorubrum kn-keyword=Methylorubrum END start-ver=1.4 cd-journal=joma no-vol=141 cd-vols= no-issue=10 article-no= start-page=1155 end-page=1160 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Biophysical and Biochemical Research of Animal Rhodopsins kn-title=光受容タンパク質・ロドプシンの生物物理化学研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Opsins (also called animal rhodopsins) are universal photoreceptive proteins that provide the molecular basis of visual and nonvisual photoreception in animals, including humans. Opsins consist of seven helical a-transmembrane domains and use retinal, a derivative of vitamin A, as a chromophore. In many opsins, light absorption triggers photoisomerization from 11-cis retinal to all-trans retinal, resulting in activation via dynamic structural changes in the protein moiety. Activated opsins stimulate cognate trimeric G proteins to induce signal transduction cascades in cells. Recently, molecular and physiological analyses of diverse opsins have progressively advanced. This review introduces the molecular basis and physiological unctions of opsins. Based on the functions of opsins, I will discuss the potential of opsins as target molecules to treat and prevent visual and nonvisual diseases such as sleep disorder and depression. en-copyright= kn-copyright= en-aut-name=KojimaKeiichi en-aut-sei=Kojima en-aut-mei=Keiichi kn-aut-name=小島慧一 kn-aut-sei=小島 kn-aut-mei=慧一 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域 en-keyword=rhodopsin kn-keyword=rhodopsin en-keyword=opsin kn-keyword=opsin en-keyword=retinal kn-keyword=retinal en-keyword=G protein coupled receptor kn-keyword=G protein coupled receptor en-keyword=vision kn-keyword=vision END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=715545 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of a Novel Quinvirus in the Family Betaflexiviridae That Infects Winter Wheat en-subtitle= kn-subtitle= en-abstract= kn-abstract=Yellow mosaic disease in winter wheat is usually attributed to the infection by bymoviruses or furoviruses; however, there is still limited information on whether other viral agents are also associated with this disease. To investigate the wheat viromes associated with yellow mosaic disease, we carried out de novo RNA sequencing (RNA-seq) analyses of symptomatic and asymptomatic wheat-leaf samples obtained from a field in Hokkaido, Japan, in 2018 and 2019. The analyses revealed the infection by a novel betaflexivirus, which tentatively named wheat virus Q (WVQ), together with wheat yellow mosaic virus (WYMV, a bymovirus) and northern cereal mosaic virus (a cytorhabdovirus). Basic local alignment search tool (BLAST) analyses showed that the WVQ strains (of which there are at least three) were related to the members of the genus Foveavirus in the subfamily Quinvirinae (family Betaflexiviridae). In the phylogenetic tree, they form a clade distant from that of the foveaviruses, suggesting that WVQ is a member of a novel genus in the Quinvirinae. Laboratory tests confirmed that WVQ, like WYMV, is potentially transmitted through the soil to wheat plants. WVQ was also found to infect rye plants grown in the same field. Moreover, WVQ-derived small interfering RNAs accumulated in the infected wheat plants, indicating that WVQ infection induces antiviral RNA silencing responses. Given its common coexistence with WYMV, the impact of WVQ infection on yellow mosaic disease in the field warrants detailed investigation. en-copyright= kn-copyright= en-aut-name=KondoHideki

的理解への学際的アプローチ―大学における授業実践の試み― en-subtitle= kn-subtitle= en-abstract=Practical lessons for liberal arts in university aimed at education for sustainable development (ESD)-oriented understanding of the natural environmental systems were conducted through collaboration between meteorological and botanical scientific studies. As the first trial, some interdisciplinary themes were identified, based on subject contents in science education in which the relationship between weather/seasons/climate and plants is important. In particular, an analysis of the lesson, “Seasons and plants”, revealed that phenology was helpful in enhancing students’ understanding of the relationship between the seasonal cycle of weather/climate and plant growth and responses to the environment associated with ESD. These practical lessons proved that collaboration between meteorology and botany is valuable for both the promotion of ESD-oriented understanding of the natural environmental systems and cross-cutting consideration of the subject content in science education, providing a promising approach for teacher education. kn-abstract=理科の学問分野である気象学と植物学との連携により，持続可能な開発のための教育（ESD）を志向した自然環境系の理解を目指し，大学の教科・分野横断的な科目における授業実践を行った。最初の試みとして，気象・季節・気候および植物との関連が重要となる理科の教科内容をベースに，学際的な側面を持ついくつかのテーマが見出された。とりわけ，生物季節（フェノロジー）は，ESD に関連した気象・気候の季節サイクルと植物の成長および環境応答との関わりに関する学生の理解を促進するうえで有用であることが，授業分析から示唆された。これらの授業実践から，気象学と植物学との連携が，自然環境系の ESD 的理解の促進のみならず，教科内容構成の分野横断的な検討にも役立ち，教師教育のためのアプローチとして有望である可能性が示された。 en-copyright= kn-copyright= en-aut-name=HARADATaro en-aut-sei=HARADA en-aut-mei=Taro kn-aut-name=原田太郎 kn-aut-sei=原田 kn-aut-mei=太郎 aut-affil-num=1 ORCID= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 en-keyword=ESD kn-keyword=ESD en-keyword=教科内容構成 (subject contents organization) kn-keyword=教科内容構成 (subject contents organization) en-keyword=東アジアの気候系 (climate system in East Asia) kn-keyword=東アジアの気候系 (climate system in East Asia) en-keyword=生物季節 (phenology) kn-keyword=生物季節 (phenology) en-keyword=園芸学 (horticulture) kn-keyword=園芸学 (horticulture) END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201111 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The role of clockwork orange in the circadian clock of the cricket Gryllus bimaculatus en-subtitle= kn-subtitle= en-abstract= kn-abstract=The circadian clock generates rhythms of approximately 24 h through periodic expression of the clock genes. In insects, the major clock genes period (per) and timeless (tim) are rhythmically expressed upon their transactivation by CLOCK/CYCLE, with peak levels in the early night. In Drosophila, clockwork orange (cwo) is known to inhibit the transcription of per and tim during the daytime to enhance the amplitude of the rhythm, but its function in other insects is largely unknown. In this study, we investigated the role of cwo in the clock mechanism of the cricket Gryllus bimaculatus. The results of quantitative RT-PCR showed that under a light/dark (LD) cycle, cwo is rhythmically expressed in the optic lobe (lamina-medulla complex) and peaks during the night. When cwo was knocked down via RNA interference (RNAi), some crickets lost their locomotor rhythm, while others maintained a rhythm but exhibited a longer free-running period under constant darkness (DD). In cwo(RNAi) crickets, all clock genes except for cryptochrome 2 (cry2) showed arrhythmic expression under DD; under LD, some of the clock genes showed higher mRNA levels, and tim showed rhythmic expression with a delayed phase. Based on these results, we propose that cwo plays an important role in the cricket circadian clock. en-copyright= kn-copyright= en-aut-name=TomiyamaYasuaki en-aut-sei=Tomiyama en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinoharaTsugumichi en-aut-sei=Shinohara en-aut-mei=Tsugumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsukaMirai en-aut-sei=Matsuka en-aut-mei=Mirai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitoTaro en-aut-sei=Mito en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Technology, Industrial and Social Sciences, Tokushima University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Circadian clock kn-keyword=Circadian clock en-keyword=Clockwork orange kn-keyword=Clockwork orange en-keyword=Clock gene kn-keyword=Clock gene en-keyword=Cricket kn-keyword=Cricket en-keyword=cry2 kn-keyword=cry2 en-keyword=Molecular oscillation kn-keyword=Molecular oscillation en-keyword=Locomotor rhythm kn-keyword=Locomotor rhythm END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=イネの亜鉛吸収に関する生理学的及び分子生物学的解析 kn-title=Physiological and Molecular Characterization of Zinc Uptake in Rice en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HuangSheng en-aut-sei=Huang en-aut-mei=Sheng kn-aut-name=黄勝 kn-aut-sei=黄 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=生物活性天然物の立体発散的合成研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WadasHiroko en-aut-sei=Wadas en-aut-mei=Hiroko kn-aut-name=和田寛子 kn-aut-sei=和田 kn-aut-mei=寛子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol=132 cd-vols= no-issue=2 article-no= start-page=60 end-page=67 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hepatitis C virus (HCV)：Diversity and variation of RNA genome kn-title=C型肝炎ウイルス（HCV）：RNAゲノムの多様性と変異性 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name=加藤宣之 kn-aut-sei=加藤 kn-aut-mei=宣之 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　腫瘍ウイルス学 en-keyword=HCV ゲノム kn-keyword=HCV ゲノム en-keyword=レプリコン複製細胞 kn-keyword=レプリコン複製細胞 en-keyword=長期継代培養 kn-keyword=長期継代培養 en-keyword=遺伝子解析 kn-keyword=遺伝子解析 en-keyword=準種 kn-keyword=準種 END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1-3 article-no= start-page=215 end-page=223 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=200305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Orchid Fleck Virus: Brevipalpus californicus Mite Transmission, Biological Properties and Genome Structure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Orchid fleck virus (OFV) causes necrotic or chlorotic ring spots and fleck symptoms in many orchid species world-wide. The virus has non-enveloped, bacilliform particles of about 40 nm × 100–150 nm and is sap-transmissible to several plant species. OFV is transmitted by the mite Brevipalpus californicus (Banks) in a persistent manner and efficiently transmitted by both adults and nymphs, but not by larvae. Viruliferous mites retain their infectivity for 3 weeks on a virus-immune host. The genome of OFV consists of two molecules of 6431 (RNA1) and 6001 nucleotides (RNA2). The RNAs have conserved and complementary terminal sequences. RNA1 contains five open reading frames (ORF), and RNA2 encodes a single ORF. Although some of the encoded proteins of OFV have sequences similar to those of proteins of plant rhabdoviruses, OFV differs from viruses in the family Rhabdoviridae in having a bipartite genome. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Bioresources, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Bioresources, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Bioresources, Okayama University kn-affil= en-keyword=Brevipalpus californicus kn-keyword=Brevipalpus californicus en-keyword=mite transmission kn-keyword=mite transmission en-keyword=orchids kn-keyword=orchids en-keyword=orchid fleck virus kn-keyword=orchid fleck virus en-keyword=plant virus kn-keyword=plant virus en-keyword=rhabdovirus kn-keyword=rhabdovirus en-keyword=virus genome structure kn-keyword=virus genome structure END start-ver=1.4 cd-journal=joma no-vol=154 cd-vols= no-issue=1 article-no= start-page=37 end-page=45 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification and characterization of structural proteins of orchid fleck virus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Orchid fleck virus (OFV) has a bipartite negative-sense RNA genome with sequence similarities to plant rhabdoviruses. The non-enveloped bullet-shaped particles of OFV are similar to those of the internal ribonucleoprotein (RNP)-M protein structure of rhabdoviruses, but they are about half the size of typical plant rhabdoviruses. Purified preparations contained intact bullet-shaped and filamentous particles. The filamentous particles showed a tightly coiled coil structure or a coiled structure with a helical twist, which resembles the RNP complex of rhabdoviruses. OFV bullet-shaped particles were structurally stable in solutions containing 2% Triton X-100 and 0.8 M NaCl. Western blot analyses revealed that the bullet-shaped particles contained N, P and M proteins, while filamentous particles contained mainly N and P proteins. In addition, a small amount of the L protein was detected in both types of particles. Thus, the structural proteins of OFV have properties similar to those of rhabdoviruses, except that the particles are non-enveloped and are relatively resistant to detergent-treatment under high-salt conditions. en-copyright= kn-copyright= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaTakanori en-aut-sei=Maeda en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Bioresources, Okayama University kn-affil= affil-num=2 en-affil=College of Bioresource Sciences, Nihon University kn-affil= affil-num=3 en-affil=Research Institute for Bioresources, Okayama University kn-affil= en-keyword=Rabies kn-keyword=Rabies en-keyword=ORF4 Protein kn-keyword=ORF4 Protein en-keyword=Sucrose Density Gradient Centrifugation kn-keyword=Sucrose Density Gradient Centrifugation en-keyword=Coil Coil Structure kn-keyword=Coil Coil Structure en-keyword=Potential Glycosylation Site kn-keyword=Potential Glycosylation Site END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=1 article-no= start-page=219 end-page=232 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathogenetic roles of beet necrotic yellow vein virus RNA5 in the exacerbation of symptoms and yield reduction, development of scab‐like symptoms, and Rz1‐resistance breaking in sugar beet en-subtitle= kn-subtitle= en-abstract= kn-abstract=Beet necrotic yellow vein virus (BNYVV) generally has a four‐segmented positive‐sense RNA genome (RNAs 1–4), but some European and most Asian strains have an additional segment, RNA5. This study examined the effect of RNA5 and RNA3 on different sugar beet cultivars using a Polymyxa‐mediated inoculation system under field and laboratory conditions. In field tests, the degree of sugar yield served as an index for assessing the virulence of BNYVV strains. Japanese A‐II type isolates without RNA5 caused mostly 15%–90% sugar yield reductions, depending on the susceptibility of sugar beet cultivars, whereas the isolates with RNA5 induced more than 90% yield losses in the seven susceptible cultivars, but small yield losses in one Rz1‐resistant and Rizor cultivars. However, a laboratory‐produced isolate containing RNA5 but lacking RNA3 caused higher yield losses in Rizor than in susceptible plants, and induced scab‐like symptoms on the root surface of both susceptible and resistant plants. In laboratory tests, A‐II type isolates without RNA5 had low viral RNA accumulation levels in roots of Rizor and Rz1‐resistant plants at early stages of infection, but in the presence of RNA5, viral RNA3 accumulation levels increased remarkably. This increased RNA3 accumulation was not observed in roots of the WB42 accession with the Rz2 gene. In contrast, the presence of RNA3 did not affect RNA5 accumulation levels. Collectively, this study demonstrated that RNA5 is involved in the development of scab‐like symptoms and the enhancement of RNA3 accumulation, and suggests these characteristics of RNA5 are associated with Rz1‐resistance breaking. en-copyright= kn-copyright= en-aut-name=TamadaTetsuo en-aut-sei=Tamada en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UchinoHirokatsu en-aut-sei=Uchino en-aut-mei=Hirokatsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KusumeToshimi en-aut-sei=Kusume en-aut-mei=Toshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Iketani‐SaitoMinako en-aut-sei=Iketani‐Saito en-aut-mei=Minako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChibaSotaro en-aut-sei=Chiba en-aut-mei=Sotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndikaIda Bagus en-aut-sei=Andika en-aut-mei=Ida Bagus kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=2 en-affil=Research Center, Nippon Beet Sugar Mfg.

Here, we report interplay between two RNA viruses, yado-nushi virus 1 (YnV1) and yado-kari virus 1 (YkV1), in a phytopathogenic fungus, Rosellinia necatrix2. YkV1 has a close phylogenetic affinity to positive-sense, single-stranded (+)ssRNA viruses such as animal caliciviruses3, while YnV1 has an undivided double-stranded (ds) RNA genome with a resemblance to fungal totiviruses4. Virion transfection and infectious full-length cDNA transformation has shown that YkV1 depends on YnV1 for viability, although it probably encodes functional RNA-dependent RNA polymerase (RdRp). Immunological and molecular analyses have revealed trans-encapsidation of not only YkV1 RNA but also RdRp by the capsid protein of the other virus (YnV1), and enhancement of YnV1 accumulation by YkV1. This study demonstrates interplay in which the capsidless (+)ssRNA virus (YkV1), hijacks the capsid protein of the dsRNA virus (YnV1), and replicates as if it were a dsRNA virus. en-copyright= kn-copyright= en-aut-name=ZhangRui en-aut-sei=Zhang en-aut-mei=Rui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HisanoSakae en-aut-sei=Hisano en-aut-mei=Sakae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoHideki en-aut-sei=Kondo en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanematsuSatoko en-aut-sei=Kanematsu en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiNobuhiro en-aut-sei=Suzuki en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=NARO Institute of Fruit Tree Science kn-affil= affil-num=6 en-affil=Agrivirology Laboratory, Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Molecular evolution kn-keyword=Molecular evolution en-keyword=Viral genetics kn-keyword=Viral genetics END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=16 article-no= start-page=4778 end-page=4796 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low temperature modulates natural peel degreening in lemon fruit independently of endogenous ethylene en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peel degreening is an important aspect of fruit ripening in many citrus fruit, and previous studies have shown that it can be advanced by ethylene treatment or by low-temperature storage. However, the important regulators and pathways involved in natural peel degreening remain largely unknown. To determine how natural peel degreening is regulated in lemon fruit (Citrus limon), we studied transcriptome and physiochemical changes in the flavedo in response to ethylene treatment and low temperatures. Treatment with ethylene induced rapid peel degreening, which was strongly inhibited by the ethylene antagonist, 1-methylcyclopropene (1-MCP). Compared with 25 degrees C, moderately low storage temperatures of 5-20 degrees C also triggered peel degreening. Surprisingly, repeated 1-MCP treatments failed to inhibit the peel degreening induced by low temperature. Transcriptome analysis revealed that low temperature and ethylene independently regulated genes associated with chlorophyll degradation, carotenoid metabolism, photosystem proteins, phytohormone biosynthesis and signalling, and transcription factors. Peel degreening of fruit on trees occurred in association with drops in ambient temperature, and it coincided with the differential expression of low temperature-regulated genes. In contrast, genes that were uniquely regulated by ethylene showed no significant expression changes during on-tree peel degreening. Based on these findings, we hypothesize that low temperature plays a prominent role in regulating natural peel degreening independently of ethylene in citrus fruit. en-copyright= kn-copyright=

kn-title=Lanthanide-Dependent Methanol and Formaldehyde Oxidation inMethylobacterium aquaticumStrain 22A en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lanthanides (Ln) are an essential cofactor for XoxF-type methanol dehydrogenases (MDHs) in Gram-negative methylotrophs. The Ln(3+)dependency of XoxF has expanded knowledge and raised new questions in methylotrophy, including the differences in characteristics of XoxF-type MDHs, their regulation, and the methylotrophic metabolism including formaldehyde oxidation. In this study, we genetically identified one set of Ln(3+)- and Ca2+-dependent MDHs (XoxF1 and MxaFI), that are involved in methylotrophy, and an ExaF-type Ln(3+)-dependent ethanol dehydrogenase, among six MDH-like genes inMethylobacterium aquaticumstrain 22A. We also identified the causative mutations in MxbD, a sensor kinase necessary formxaFexpression andxoxF1repression, for suppressive phenotypes inxoxF1mutants defective in methanol growth even in the absence of Ln(3+). Furthermore, we examined the phenotypes of a series of formaldehyde oxidation-pathway mutants (fae1,fae2,mchin the tetrahydromethanopterin (H4MPT) pathway andhgdin the glutathione-dependent formaldehyde dehydrogenase (GSH) pathway). We found that MxaF produces formaldehyde to a toxic level in the absence of the formaldehyde oxidation pathways and that either XoxF1 or ExaF can oxidize formaldehyde to alleviate formaldehyde toxicity in vivo. Furthermore, the GSH pathway has a supportive role for the net formaldehyde oxidation in addition to the H4MPT pathway that has primary importance. Studies on methylotrophy inMethylobacteriumspecies have a long history, and this study provides further insights into genetic and physiological diversity and the differences in methylotrophy within the plant-colonizing methylotrophs. en-copyright= kn-copyright= en-aut-name=YanpiratPatcha en-aut-sei=Yanpirat en-aut-mei=Patcha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakatsujiYukari en-aut-sei=Nakatsuji en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiragaShota en-aut-sei=Hiraga en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujitaniYoshiko en-aut-sei=Fujitani en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IzumiTerumi en-aut-sei=Izumi en-aut-mei=Terumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MasudaSachiko en-aut-sei=Masuda en-aut-mei=Sachiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MitsuiRyoji en-aut-sei=Mitsui en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakagawaTomoyuki en-aut-sei=Nakagawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Department of Biochemistry, Faculty of Science, Okayama University of Science kn-affil= affil-num=8 en-affil=The United Graduate School of Agricultural Science, Gifu University kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=lanthanide kn-keyword=lanthanide en-keyword=methylotroph kn-keyword=methylotroph en-keyword=XoxF kn-keyword=XoxF en-keyword=methanol dehydrogenase kn-keyword=methanol dehydrogenase en-keyword=Methylobacteriumspecies kn-keyword=Methylobacteriumspecies END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=5 article-no= start-page=1683 end-page=1696 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Honeydew-associated microbes elicit defense responses against brown planthopper in rice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Feeding of sucking insects, such as the rice brown planthopper (Nilaparvata lugens; BPH), causes only limited mechanical damage on plants that is otherwise essential for injury-triggered defense responses against herbivores. In pursuit of complementary BPH elicitors perceived by plants, we examined the potential effects of BPH honeydew secretions on the BPH monocot host, rice (Oryza sativa). We found that BPH honeydew strongly elicits direct and putative indirect defenses in rice, namely accumulation of phytoalexins in the leaves, and release of volatile organic compounds from the leaves that serve to attract natural enemies of herbivores, respectively. We then examined the elicitor active components in the honeydew and found that bacteria in the secretions are responsible for the activation of plant defense. Corroborating the importance of honeydew-associated microbiota for induced plant resistance, BPHs partially devoid of their microbiota via prolonged antibiotics ingestion induced significantly less defense in rice relative to antibiotic-free insects applied to similar groups of plants. Our data suggest that rice plants may additionally perceive herbivores via their honeydew-associated microbes, allowing them to discriminate between incompatible herbivores—that do not produce honeydew—and those that are compatible and therefore dangerous. en-copyright= kn-copyright= en-aut-name=WariDavid en-aut-sei=Wari en-aut-mei=David kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KabirMd Alamgir en-aut-sei=Kabir en-aut-mei=Md Alamgir kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MujionoKadis en-aut-sei=Mujiono en-aut-mei=Kadis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HojoYuko en-aut-sei=Hojo en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShinyaTomonori en-aut-sei=Shinya en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakataniHiroko en-aut-sei=Nakatani en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=GalisIvan en-aut-sei=Galis en-aut-mei=Ivan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=4 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Honeydew-associated microorganisms kn-keyword=Honeydew-associated microorganisms en-keyword=phytoalexins kn-keyword=phytoalexins en-keyword=plant defense kn-keyword=plant defense en-keyword=rice (Oryza sativa) kn-keyword=rice (Oryza sativa) en-keyword=rice brown planthopper (Nilaparvata lugens) kn-keyword=rice brown planthopper (Nilaparvata lugens) en-keyword=sucking insect kn-keyword=sucking insect END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Spiranthes sinensis (Pers.)

However, its extension to a larger sample size has been restrained owing to the limited throughput of toxicity bioassays. Here we reported the development of a high-throughput method of TIE Phase I. This newly developed method was assisted by the fluorescence-based cellular oxidation (CO) biosensor fabricated with roGFP2-expressing bacterial cells in 96-well microplate format. The assessment of four river water samples from Langat river basin by this new method demonstrated that the contaminant composition of the four samples can be classified into two distinct groups. The entire toxicity assay consisted of 2338 tests was completed within 12 h with a fluorescence microplate reader. Concurrently, the sample volume for each assay was reduced to 50 μL, which is 600 to 4700 times lesser to compare with conventional bioassays. These imply that the throughput of the CO biosensor-assisted TIE Phase I is now feasible for constructing a large-scale toxicity monitoring system, which would cover a whole watershed scale.

kn-abstract= Acid mine drainage (AMD) is acidic and generally enriched with iron, aluminum, sulfate and heavy metals, such as lead and cadmium. AMD is a growing problem of emerging concern that cause detrimental effects to the environment and living organisms. Yanahara mine in Misaki Town, Okayama, Japan, had mainly produced pyrite for sulfuric acid manufacture. Although it was closed in 1991, AMD is being generated from the mine now. A passive treatment based on the biological oxidation of ferrous iron is a promising strategy for AMD remediation. AMD from Yanahara mine is treated in a plant using iron-oxidizing bacteria, Acidithiobacillus ferrooxidans and Ferrovum spp. The AMD generation continues for several centuries with dramatic consequences on the receiving environments. Therefore, the development of sustainable and cost effective treatment process is required. A development of the effective biological treatment process with an iron oxidation reactor operated at pH 3.5 is described in this report. Economic aspects are also discussed. en-copyright= kn-copyright= en-aut-name=KamimuraKazuo en-aut-sei=Kamimura en-aut-mei=Kazuo kn-aut-name=上村一雄 kn-aut-sei=上村 kn-aut-mei=一雄 aut-affil-num=1 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name=金尾忠芳 kn-aut-sei=金尾 kn-aut-mei=忠芳 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=acid mine drainage kn-keyword=acid mine drainage en-keyword=bioremediation kn-keyword=bioremediation en-keyword=iron-oxidizing bacteria kn-keyword=iron-oxidizing bacteria en-keyword=microbial community kn-keyword=microbial community en-keyword=Acidithiobacillus ferrooxidans kn-keyword=Acidithiobacillus ferrooxidans END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=2 article-no= start-page=437 end-page=447 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180716 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The mechanism of SO2 -induced stomatal closure differs from O3 and CO2 responses and is mediated by nonapoptotic cell death in guard cells. en-subtitle= kn-subtitle= en-abstract= kn-abstract= Plants closing stomata in the presence of harmful gases is believed to be a stress avoidance mechanism. SO2 , one of the major airborne pollutants, has long been reported to induce stomatal closure, yet the mechanism remains unknown. Little is known about the stomatal response to airborne pollutants besides O3 . SLOW ANION CHANNEL-ASSOCIATED 1 (SLAC1) and OPEN STOMATA 1 (OST1) were identified as genes mediating O3 -induced closure. SLAC1 and OST1 are also known to mediate stomatal closure in response to CO2 , together with RESPIRATORY BURST OXIDASE HOMOLOGs (RBOHs). The overlaying roles of these genes in response to O3 and CO2 suggested that plants share their molecular regulators for airborne stimuli. Here, we investigated and compared stomatal closure event induced by a wide concentration range of SO2 in Arabidopsis through molecular genetic approaches. O3 - and CO2 -insensitive stomata mutants did not show significant differences from the wild type in stomatal sensitivity, guard cell viability, and chlorophyll content revealing that SO2 -induced closure is not regulated by the same molecular mechanisms as for O3 and CO2 . Nonapoptotic cell death is shown as the reason for SO2 -induced closure, which proposed the closure as a physicochemical process resulted from SO2 distress, instead of a biological protection

kn-abstract=Runx3 is a transcription factor that belongs to the Runx family. Female Runx3 knockout (Runx3−⁄−) mouse was anovulatory and infertile. Ovarian transplantation experiment suggested that lack of ovulation in Runx3−⁄− mice was caused by alteration of gonadotropin secretion in Runx3−⁄− mice. Cyp11a1 mRNA expression was less in Runx3−⁄− mouse ovaries than in wt ones. Hypothalamic Gnrh1 mRNA was increased, and Kiss1 mRNA expression in the anteroventral periventricular nucleus was decreased, but Kisspeptin mRNA in the arcuate nucleus was increased in Runx3-/- mice. Pituitary Fshb mRNA levels were increased in Runx3−⁄− mice. Cholesterol side-chain cleavage enzyme gene (Cyp11a1) expression was decreased in ovaries of Runx3−⁄− mice. These findings suggest that anovulation in Runx3−⁄− mice was partly due to the alterations in hypothalamus-pituitary-ovary system. Runx3 plays a key role in female reproduction through alteration of gonadotropin secretion. en-copyright= kn-copyright= en-aut-name=TakahashiSumio en-aut-sei=Takahashi en-aut-mei=Sumio kn-aut-name=高橋純夫 kn-aut-sei=高橋 kn-aut-mei=純夫 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科高次生物科学講座･生体統御学分野 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Aspergillus ustus 由来の生理活性化合物が有する独特の抗微生物活性 kn-title=Unique antimicrobial activity of bioactive compound produced by Aspergillus ustus en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=NatthapatSohsomboon kn-aut-sei=Natthapat kn-aut-mei=Sohsomboon aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=キイロショウジョウバエの変態期における発生タイミングを決める生物タイマーの分子機構と栄養シグナルの影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NishidaHaruka en-aut-sei=Nishida en-aut-mei=Haruka kn-aut-name=西田遥 kn-aut-sei=西田 kn-aut-mei=遥 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Streptococcus mutans における分子シャペロンDnaKの分子生物学的解明 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YoshidaEri en-aut-sei=Yoshida en-aut-mei=Eri kn-aut-name=吉田衣里 kn-aut-sei=吉田 kn-aut-mei=衣里 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ベトナム酪農の制限要因及び発展性に関する微生物学的研究 kn-title=Microbiological studies on constraints and opportunities of dairy cattle production in Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Tran Thi Minh Tu en-aut-sei=Tran Thi Minh Tu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=8 article-no= start-page=1779 end-page=1990 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Involvement of OST1 Protein Kinase and PYR/PYL/RCAR Receptors in Methyl Jasmonate-Induced Stomatal Closure in Arabidopsis Guard Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract= Methyl jasmonate (MeJA) induces stomatal closure. It has been shown that stomata of many ABA-insensitive mutants are also insensitive to MeJA, and a low amount of ABA is a prerequisite for the MeJA response. However, the molecular mechanisms of the interaction between ABA and MeJA signaling remain to be elucidated. Here we studied the interplay of signaling of the two hormones in guard cells using the quadruple ABA receptor mutant pyr1 pyl1 pyl2 pyl4 and ABA-activated protein kinase mutants ost1-2 and srk2e. In the quadruple mutant, MeJA-induced stomatal closure, H2O2 production, nitric oxide (NO) production, cytosolic alkalization and plasma membrane Ca(2+)-permeable current (ICa) activation were not impaired. At the same time, the inactivation of the inward-rectifying K(+) current was impaired. In contrast to the quadruple mutant, MeJA-induced stomatal closure, H2O2 production, NO production and cytosolic alkalization were impaired in ost1-2 and srk2e as well as in aba2-2, the ABA-deficient mutant. The activation of ICa was also impaired in srk2e. Collectively, these results indicated that OST1 was essential for MeJA-induced stomatal closure, while PYR1, PYL1, PYL2 and PYL4 ABA receptors were not sufficient factors. MeJA did not appear to activate OST1 kinase activity. This implies that OST1 mediates MeJA signaling through an undetectable level of activity or a non-enzymatic action. MeJA induced the expression of an ABA synthesis gene, NCED3, and increased ABA contents only modestly. Taken together with previous reports, this study suggests that MeJA signaling in guard cells is primed by ABA and is not brought about through the pathway mediated by PYR1, PYL1 PYL2 and PYL4. en-copyright= kn-copyright= en-aut-name=YinYe en-aut-sei=Yin en-aut-mei=Ye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AdachiYuji en-aut-sei=Adachi en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=ABA kn-keyword=ABA en-keyword=ABA receptors kn-keyword=ABA receptors en-keyword=Arabidopsis thaliana kn-keyword=Arabidopsis thaliana en-keyword=Guard cells kn-keyword=Guard cells en-keyword=Methyl jasmonate kn-keyword=Methyl jasmonate en-keyword=OST1 protein kinase kn-keyword=OST1 protein kinase END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=7 article-no= start-page=1422 end-page=1431 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of hepatitis C virus production reporter-assay systems using two different hepatoma cell lines en-subtitle= kn-subtitle= en-abstract= kn-abstract=　A hepatitis C virus (HCV) infection system was developed previously using the HCV JFH-1 strain (genotype 2a) and HuH-7 cells, and this cell culture is so far the only robust production system for HCV. In patients with chronic hepatitis C, the virological effects of pegylated interferon and ribavirin therapy differ depending on the HCV strain and the genetic background of the host. Recently, we reported the hepatoma-derived Li23 cell line, in which the JFH-1 life cycle is reproduced at a level almost equal to that in HuH-7-derived RSc cells. To monitor the HCV life cycle more easily, we here developed JFH-1 reporter-assay systems using both HuH-7- and Li23-derived cell lines. To identify any genetic mutations by long-term cell culture, HCV RNAs in HuH-7 cells were amplified 130 days after infection and subjected to sequence analysis to find adaptive mutation(s) for robust virus replication. We identified two mutations, H2505Q and V2995L, in the NS5B region. V2995L but not H2505Q enhanced JFH-1 RNA replication. However, we found that H2505Q but not V2995L enhanced HCV RNA replication of strain O (genotype 1b). We also selected highly permissive D7 cells by serial subcloning of Li23 cells. The expression levels of claudin-1 and Niemann-Pick C1-like 1 in D7 cells are higher than those in parental Li23 cells. In this study, we developed HCV JFH-1 reporter-assay systems using two distinct hepatoma cell lines, HuH-7 and Li23. The mutations in NS5B resulted in different effects on strains O and JFH-1 HCV RNA replication. en-copyright= kn-copyright= en-aut-name=TakedaMidori en-aut-sei=Takeda en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AriumiYasuo en-aut-sei=Ariumi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakitaTakaji en-aut-sei=Wakita en-aut-mei=Takaji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Tumor Virology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Tumor Virology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Tumor Virology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Virology II, National Institute of Infectious Disease kn-affil= affil-num=5 en-affil=Department of Tumor Virology, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=167 cd-vols= no-issue=1 article-no= start-page=74 end-page=85 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201207 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of host genes showing differential expression profiles with cell-based long-term replication of hepatitis C virus RNA en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Persistent hepatitis C virus (HCV) infection frequently causes hepatocellular carcinoma. However, the mechanisms of HCV-associated hepatocarcinogenesis and disease progression are unclear. Although the human hepatoma cell line, HuH-7, has been widely used as the only cell culture system for robust HCV replication, we recently developed new human hepatoma Li23 cell line-derived OL, OL8, OL11, and OL14 cells, in which genome-length HCV RNA (O strain of genotype 1b) efficiently replicates. OL, OL8, OL11, and OL14 cells were cultured for more than 2 years. We prepared cured cells from OL8 and OL11 cells by interferon-γ treatment. The cured cells were also cultured for more than 2 years. cDNA microarray and RT-PCR analyses were performed using total RNAs prepared from these cells. We first selected several hundred highly or moderately expressed probes, the expression levels of which were upregulated or downregulated at ratios of more than 2 or less than 0.5 in each set of compared cells (e.g., parent OL8 cells versus OL8 cells cultured for 2 years). From among these probes, we next selected those whose expression levels commonly changed during a 2-year culture of genome-length HCV RNA-replicating cells, but which did not change during a 2-year culture period in cured cells. We further examined the expression levels of the selected candidate genes by RT-PCR analysis using additional specimens from the cells cultured for 3.5 years. Reproducibility of the RT-PCR analysis using specimens from recultured cells was also confirmed. Finally, we identified 5 upregulated genes and 4 downregulated genes, the expression levels of which were irreversibly altered during 3.5-year replication of HCV RNA. These genes may play roles in the optimization of the environment in HCV RNA replication, or may play key roles in the progression of HCV-associated hepatic diseases. en-copyright= kn-copyright= en-aut-name=SejimaHiroe en-aut-sei=Sejima en-aut-mei=Hiroe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoriKyoko en-aut-sei=Mori en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AriumiYasuo en-aut-sei=Ariumi en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=HCV kn-keyword=HCV en-keyword=HCV RNA replication system kn-keyword=HCV RNA replication system en-keyword=Li23 cells kn-keyword=Li23 cells en-keyword=Long-term RNA replication kn-keyword=Long-term RNA replication en-keyword=Upregulated host genes kn-keyword=Upregulated host genes en-keyword=Downregulated host genes kn-keyword=Downregulated host genes END start-ver=1.4 cd-journal=joma no-vol=129 cd-vols= no-issue=2 article-no= start-page=81 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2016 Incentive Award of the Okayama Medical Association in General Medical Science (2016 Yuuki Prize) kn-title=平成28年度岡山医学会賞　総合研究奨励賞（結城賞） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name=阪口政清 kn-aut-sei=阪口 kn-aut-mei=政清 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Cell Biolgy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　細胞生物学 END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=31 end-page=34 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Identification of Marker Gene of Pars Tuberalis Morphogenesis in Chicken Embryo.

The mechanisms of development of PD has been well studied, and the cell differentiation of PD has been well understood. However, the morphogenesis and the differentiation of PT are still unclear, and the gene expression during the PT development remains largely unknown. In this study, we explored the specifically expressing genes in PT during development and analyzed its spatiotemporal expressions pattern. Microarray analysis on laser-captured PT and PD tissues obtained from chicken embryos on embryonic day 10 (E10.0) showed high expressing genes, Cytokine-like 1 (CYTL1) and Gap junction protein alpha 5 (GJA5) in PT. A detail analysis of spatiotemporal expressions pattern during chick embryo development by in situ hybridization revealed that CYTL1 mRNA was first detected in lateral head ectoderm and ventral head ectoderm in E1.5. The CYTL1 expressions moved into Rathke’s pouch at E2.5, then it was localized in PT primordium and continuously expressed in PT primordium until E12.0. On the other hand, GJA5 mRNA was transiently detected in PT primordium from E6 to E14.0, while the expression was not detected in PD during development. These results suggested that these genes may be involved in the regulation mechanism of PT development and could be a useful marker in the PT development. en-copyright= kn-copyright= en-aut-name=AizawaSayaka en-aut-sei=Aizawa en-aut-mei=Sayaka kn-aut-name=相澤清香 kn-aut-sei=相澤 kn-aut-mei=清香 aut-affil-num=1 ORCID= en-aut-name=HigakiYuriko en-aut-sei=Higaki en-aut-mei=Yuriko kn-aut-name=檜垣佑理子 kn-aut-sei=檜垣 kn-aut-mei=佑理子 aut-affil-num=2 ORCID= en-aut-name=OgoshiMaho en-aut-sei=Ogoshi en-aut-mei=Maho kn-aut-name=御輿真穂 kn-aut-sei=御輿 kn-aut-mei=真穂 aut-affil-num=3 ORCID= en-aut-name=TakeuchiSakae en-aut-sei=Takeuchi en-aut-mei=Sakae kn-aut-name=竹内栄 kn-aut-sei=竹内 kn-aut-mei=栄 aut-affil-num=4 ORCID= en-aut-name=TakahashiSumio en-aut-sei=Takahashi en-aut-mei=Sumio kn-aut-name=高橋純夫 kn-aut-sei=高橋 kn-aut-mei=純夫 aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科高次生物科学講座･生体統御学分野 affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科高次生物科学講座･生体統御学分野 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=微生物由来の非晶質鉄酸化物を用いた有機合成反応の開発 kn-title=Development of Organic Reactions with Bacteriogenic Amorphous Iron Oxide en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MandaiKyoko en-aut-sei=Mandai en-aut-mei=Kyoko kn-aut-name=萬代恭子 kn-aut-sei=萬代 kn-aut-mei=恭子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Tchnology, Okayama University kn-affil=岡山大学大学院自然科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=西日本のブナ林におけるブナ実生の生残に影響を与える非生物的要因と生物的要因 kn-title=Abiotic and biotic factors affecting the seedling survival of Fagus crenata in beech forests in western Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AkajiYasuaki en-aut-sei=Akaji en-aut-mei=Yasuaki kn-aut-name=赤路康朗 kn-aut-sei=赤路 kn-aut-mei=康朗 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=完全型と不完全型円板状外側半月の組織学的・生物学的解析 kn-title=Histological and biological comparisons between complete and incomplete discoid lateral meniscus en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=InoueHiroto en-aut-sei=Inoue en-aut-mei=Hiroto kn-aut-name=井上博登 kn-aut-sei=井上 kn-aut-mei=博登 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=新規T細胞株HOZOTによる生物製剤の腫瘍特異的デリバリー kn-title=Tumor-specific delivery of biologics by a novel T-cell line HOZOT en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OnishiTeppei en-aut-sei=Onishi en-aut-mei=Teppei kn-aut-name=大西哲平 kn-aut-sei=大西 kn-aut-mei=哲平 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=163 cd-vols= no-issue= article-no= start-page=69 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Differences in the Biological Sciences Education in Upper Secondary Level between Japan and Swiss German Zone -

Racomitrium species are most often used due to their high tolerance to desiccation. Because they grow slowly, a technology for forcing their growth is desired. We succeeded in the efficient production of R. japonicum in liquid culture. The structure of the microbial community is crucial to stabilize the culture. A culture-independent technique revealed that the cultures contain methylotrophic bacteria. Using yeast cells that fluoresce in the presence of methanol, methanol emission from the moss was confirmed, suggesting that it is an important carbon and energy source for the bacteria. We isolated Methylobacterium species from the liquid culture and studied their characteristics. The isolates were able to strongly promote the growth of some mosses including R. japonicum and seed plants, but the plant-microbe combination was important, since growth promotion was not uniform across species. One of the isolates, strain 22A, was cultivated with R. japonicum in liquid culture and in a field experiment, resulting in strong growth promotion. Mutualistic symbiosis can thus be utilized for industrial moss production. en-copyright= kn-copyright= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaiYuichiro en-aut-sei=Takai en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukawaIkko en-aut-sei=Suzukawa en-aut-mei=Ikko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkitaMotomu en-aut-sei=Akita en-aut-mei=Motomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MuraseHaruhiko en-aut-sei=Murase en-aut-mei=Haruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimbaraKazuhide en-aut-sei=Kimbara en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=2 en-affil= kn-affil=Research Institute of Environment, Agriculture and Fisheries, Osaka Prefectural Government affil-num=3 en-affil= kn-affil=Meiho-Construction affil-num=4 en-affil= kn-affil=Faculty of Biological Engineering, Kinki University affil-num=5 en-affil= kn-affil=Graduate School of Agriculture and Biological Sciences, Osaka Prefecture University affil-num=6 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=7 article-no= start-page=e40784 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120712 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-Throughput Identification and Screening of Novel Methylobacterium Species Using Whole-Cell MALDI-TOF/MS Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Methylobacterium species are ubiquitous α-proteobacteria that reside in the phyllosphere and are fed by methanol that is emitted from plants. In this study, we applied whole-cell matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis (WC-MS) to evaluate the diversity of Methylobacterium species collected from a variety of plants. The WC-MS spectrum was reproducible through two weeks of cultivation on different media. WC-MS spectrum peaks of M. extorquens strain AM1 cells were attributed to ribosomal proteins, but those were not were also found. We developed a simple method for rapid identification based on spectra similarity. Using all available type strains of Methylobacterium species, the method provided a certain threshold similarity value for species-level discrimination, although the genus contains some type strains that could not be easily discriminated solely by 16S rRNA gene sequence similarity. Next, we evaluated the WC-MS data of approximately 200 methylotrophs isolated from various plants with MALDI Biotyper software (Bruker Daltonics). Isolates representing each cluster were further identified by 16S rRNA gene sequencing. In most cases, the identification by WC-MS matched that by sequencing, and isolates with unique spectra represented possible novel species. The strains belonging to M. extorquens, M. adhaesivum, M. marchantiae, M. komagatae, M. brachiatum, M. radiotolerans, and novel lineages close to M. adhaesivum, many of which were isolated from bryophytes, were found to be the most frequent phyllospheric colonizers. The WC-MS technique provides emerging high-throughputness in the identification of known/novel species of bacteria, enabling the selection of novel species in a library and identification without 16S rRNA gene sequencing. en-copyright= kn-copyright= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NurettinSahin en-aut-sei=Nurettin en-aut-mei=Sahin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuyamaYumiko en-aut-sei=Matsuyama en-aut-mei=Yumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EnomotoTakashi en-aut-sei=Enomoto en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraNaoki en-aut-sei=Nishimura en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokotaAkira en-aut-sei=Yokota en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KimbaraKazuhide en-aut-sei=Kimbara en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Education, Mugla Sitki Kocman University affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=5 en-affil= kn-affil=Botanical Garden, Okayama University of Science affil-num=6 en-affil= kn-affil=Faculty of Mathematics and Natural Sciences, University of Indonesia affil-num=7 en-affil= kn-affil=Faculty of Engineering, Shizuoka University END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=11 article-no= start-page=e50480 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Catalytic Role of XoxF1 as La3+-Dependent Methanol Dehydrogenase in Methylobacterium extorquens Strain AM1 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the methylotrophic bacterium Methylobacterium extorquens strain AM1, MxaF, a Ca2+-dependent methanol dehydrogenase (MDH), is the main enzyme catalyzing methanol oxidation during growth on methanol. The genome of strain AM1 contains another MDH gene homologue, xoxF1, whose function in methanol metabolism has remained unclear. In this work, we show that XoxF1 also functions as an MDH and is La3+-dependent. Despite the absence of Ca2+ in the medium strain AM1 was able to grow on methanol in the presence of La3+. Addition of La3+ increased MDH activity but the addition had no effect on mxaF or xoxF1 expression level. We purified MDH from strain AM1 grown on methanol in the presence of La3+, and its N-terminal amino acid sequence corresponded to that of XoxF1. The enzyme contained La3+ as a cofactor. The ΔmxaF mutant strain could not grow on methanol in the presence of Ca2+, but was able to grow after supplementation with La3+. Taken together, these results show that XoxF1 participates in methanol metabolism as a La3+-dependent MDH in strain AM1. en-copyright= kn-copyright= en-aut-name=NakagawaTomoyuki en-aut-sei=Nakagawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuiRyoji en-aut-sei=Mitsui en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SasaKentaro en-aut-sei=Sasa en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TashiroShinya en-aut-sei=Tashiro en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwamaTomonori en-aut-sei=Iwama en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HayakawaTakashi en-aut-sei=Hayakawa en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiKeiichi en-aut-sei=Kawai en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Faculty of Applied Biological Science, Gifu University affil-num=2 en-affil= kn-affil=Department of Biochemistry, Faculty of Science, Okayama University of Science affil-num=3 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=4 en-affil= kn-affil=Faculty of Applied Biological Science, Gifu University affil-num=5 en-affil= kn-affil=Faculty of Applied Biological Science, Gifu University affil-num=6 en-affil= kn-affil=Faculty of Applied Biological Science, Gifu University affil-num=7 en-affil= kn-affil=Faculty of Applied Biological Science, Gifu University affil-num=8 en-affil= kn-affil=Tokai Gakuin University END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=15 article-no= start-page=6131 end-page=6141 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150415 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cryptochrome-dependent and -independent circadian entrainment circuits in Drosophila. en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Entrainment to environmental light/dark (LD) cycles is a central function of circadian clocks. In Drosophila, entrainment is achieved by Cryptochrome (CRY) and input from the visual system. During activation by brief light pulses, CRY triggers the degradation of TIMELESS and subsequent shift in circadian phase. This is less important for LD entrainment, leading to questions regarding light input circuits and mechanisms from the visual system. Recent studies show that different subsets of brain pacemaker clock neurons, the morning (M) and evening (E) oscillators, have distinct functions in light entrainment. However, the role of CRY in M and E oscillators for entrainment to LD cycles is unknown. Here, we address this question by selectively expressing CRY in different subsets of clock neurons in a cry-null (cry0) mutant background. We were able to rescue the light entrainment deficits of cry0 mutants by expressing CRY in E oscillators but not in any other clock neurons. Par domain protein 1 molecular oscillations in the E, but not M, cells of cry0 mutants still responded to the LD phase delay. This residual light response was stemming from the visual system because it disappeared when all external photoreceptors were ablated genetically.

To clarify the molecular basis of epigenetic regulation during regeneration, we focused on the function of the Gryllus Enhancer of zeste [Gb'E(z)] and Ubiquitously transcribed tetratricopeptide repeat gene on the X chromosome (Gb'Utx) homologues, which regulate methylation and demethylation of histone H3 lysine 27 (H3K27), respectively. Methylated histone H3K27 in the regenerating leg was diminished by Gb'E(z)RNAi and was increased by Gb'UtxRNAi. Regenerated Gb'E(z)RNAi cricket legs exhibited extra leg segment formation between the tibia and tarsus, and regenerated Gb'UtxRNAi cricket legs showed leg joint formation defects in the tarsus. In the Gb'E(z)RNAi regenerating leg, the Gb'dac expression domain expanded in the tarsus. By contrast, in the Gb'UtxRNAi regenerating leg, Gb'Egfr expression in the middle of the tarsus was diminished. These results suggest that regulation of the histone H3K27 methylation state is involved in the repatterning process during leg regeneration among cricket species via the epigenetic regulation of leg patterning gene expression. en-copyright= kn-copyright= en-aut-name=HamadaYoshimasa en-aut-sei=Hamada en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BandoTetsuya en-aut-sei=Bando en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraTaro en-aut-sei=Nakamura en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshimaruYoshiyasu en-aut-sei=Ishimaru en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MitoTaro en-aut-sei=Mito en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NojiSumihare en-aut-sei=Noji en-aut-mei=Sumihare kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=3 en-affil= kn-affil=Department of Life Systems, Institute of Technology and Science, The University of Tokushima Graduate School affil-num=4 en-affil= kn-affil=Department of Life Systems, Institute of Technology and Science, The University of Tokushima Graduate School affil-num=5 en-affil= kn-affil=Department of Life Systems, Institute of Technology and Science, The University of Tokushima Graduate School affil-num=6 en-affil= kn-affil=Department of Life Systems, Institute of Technology and Science, The University of Tokushima Graduate School affil-num=7 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=8 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University en-keyword=Regeneration kn-keyword=Regeneration en-keyword=Epigenetics kn-keyword=Epigenetics en-keyword=Histone H3K27 kn-keyword=Histone H3K27 en-keyword=Gryllus bimaculatus kn-keyword=Gryllus bimaculatus en-keyword=Polycomb kn-keyword=Polycomb END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=3 article-no= start-page=e91156 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140313 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Genetic Characterization of Hepatitis C Virus in Long-Term RNA Replication Using Li23 Cell Culture Systems en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　 　 The most distinguishing genetic feature of hepatitis C virus (HCV) is its remarkable diversity and variation. To understand this feature, we previously performed genetic analysis of HCV in the long-term culture of human hepatoma HuH-7-derived HCV RNA-replicating cell lines. On the other hand, we newly established HCV RNA-replicating cell lines using human hepatoma Li23 cells, which were distinct from HuH-7 cells. 　 Methodology/Principal Findings　 　 Li23-derived HCV RNA-replicating cells were cultured for 4 years. We performed genetic analysis of HCVs recovered from these cells at 0, 2, and 4 years in culture. Most analysis was performed in two separate parts: one part covered from the 5′-terminus to NS2, which is mostly nonessential for RNA replication, and the other part covered from NS3 to NS5B, which is essential for RNA replication. Genetic mutations in both regions accumulated in a time-dependent manner, and the mutation rates in the 5′-terminus-NS2 and NS3-NS5B regions were 4.0–9.0×10−3 and 2.7–4.0×10−3 base substitutions/site/year, respectively. These results suggest that the variation in the NS3-NS5B regions is affected by the pressure of RNA replication. Several in-frame deletions (3–105 nucleotides) were detected in the structural regions of HCV RNAs obtained from 2-year or 4-year cultured cells. Phylogenetic tree analyses clearly showed that the genetic diversity of HCV was expanded in a time-dependent manner. The GC content of HCV RNA was significantly increased in a time-dependent manner, as previously observed in HuH-7-derived cell systems. This phenomenon was partially due to the alterations in codon usages for codon optimization in human cells. Furthermore, we demonstrated that these long-term cultured cells were useful as a source for the selection of HCV clones showing resistance to anti-HCV agents. 　 Conclusions/Significance　 　 Long-term cultured HCV RNA-replicating cells are useful for the analysis of evolutionary dynamics and variations of HCV and for drug-resistance analysis. en-copyright= kn-copyright= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SejimaHiroe en-aut-sei=Sejima en-aut-mei=Hiroe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriKyoko en-aut-sei=Mori en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatohShinya en-aut-sei=Satoh en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=8 article-no= start-page=e72519 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=New Preclinical Antimalarial Drugs Potently Inhibit Hepatitis C Virus Genotype 1b RNA Replication en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND: Persistent hepatitis C virus (HCV) infection causes chronic liver diseases and is a global health problem. Although new triple therapy (pegylated-interferon, ribavirin, and telaprevir/boceprevir) has recently been started and is expected to achieve a sustained virologic response of more than 70% in HCV genotype 1 patients, there are several problems to be resolved, including skin rash/ageusia and advanced anemia. Thus a new type of anti-HCV drug is still needed. 　 METHODOLOGY/PRINCIPAL FINDINGS: 　 　 Recently developed HCV drug assay systems using HCV-RNA-replicating cells (e.g., HuH-7-derived OR6 and Li23-derived ORL8) were used to evaluate the anti-HCV activity of drug candidates. During the course of the evaluation of anti-HCV candidates, we unexpectedly found that two preclinical antimalarial drugs (N-89 and its derivative N-251) showed potent anti-HCV activities at tens of nanomolar concentrations irrespective of the cell lines and HCV strains of genotype 1b. We confirmed that replication of authentic HCV-RNA was inhibited by these drugs. Interestingly, however, this anti-HCV activity did not work for JFH-1 strain of genotype 2a. We demonstrated that HCV-RNA-replicating cells were cured by treatment with only N-89. A comparative time course assay using N-89 and interferon-α demonstrated that N-89-treated ORL8 cells had more rapid anti-HCV kinetics than did interferon-α-treated cells. This anti-HCV activity was largely canceled by vitamin E. In combination with interferon-α and/or ribavirin, N-89 or N-251 exhibited a synergistic inhibitory effect.　 　 CONCLUSIONS/SIGNIFICANCE:　 　 We found that the preclinical antimalarial drugs N-89 and N-251 exhibited very fast and potent anti-HCV activities using cell-based HCV-RNA-replication assay systems. N-89 and N-251 may be useful as a new type of anti-HCV reagents when used singly or in combination with interferon and/or ribavirin. en-copyright= kn-copyright= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakedaMidori en-aut-sei=Takeda en-aut-mei=Midori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriKyoko en-aut-sei=Mori en-aut-mei=Kyoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WakitaTakaji en-aut-sei=Wakita en-aut-mei=Takaji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimHye-Sook en-aut-sei=Kim en-aut-mei=Hye-Sook kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoAkira en-aut-sei=Sato en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatayaYusuke en-aut-sei=Wataya en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Virology II, National Institute of Infectious Disease affil-num=6 en-affil= kn-affil=Department of Drug Informatics, Faculty of Pharmaceutical Sciences, Okayama University affil-num=7 en-affil= kn-affil=Department of Drug Informatics, Faculty of Pharmaceutical Sciences, Okayama University affil-num=8 en-affil= kn-affil=Department of Drug Informatics, Faculty of Pharmaceutical Sciences, Okayama University affil-num=9 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=10 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=3 article-no= start-page=187 end-page=195 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Basic and clinical research regarding vascular endothelial function kn-title=血管内皮機能を対象にした基礎および臨床医学研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name=塚原宏一 kn-aut-sei=塚原 kn-aut-mei=宏一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 en-keyword=アルギニン代謝 kn-keyword=アルギニン代謝 en-keyword=一酸化窒素 kn-keyword=一酸化窒素 en-keyword=ガス生物学 kn-keyword=ガス生物学 en-keyword=血管内皮学 kn-keyword=血管内皮学 en-keyword=酸化ストレス kn-keyword=酸化ストレス END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=2015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The cyclic GMP-AMP synthetase-STING signaling pathway is required for both the innate immune response against HBV and the suppression of HBV assembly en-subtitle= kn-subtitle= en-abstract= kn-abstract=During viral replication, the innate immune response is induced through the recognition of viral replication intermediates by host factor(s). One of these host factors, cyclic GMP-AMP synthetase (cGAS), was recently reported to be involved in the recognition of viral DNA derived from DNA viruses. However, it is uncertain whether cGAS is involved in the recognition of hepatitis B virus (HBV), which is a hepatotropic DNA virus. In the present study, we demonstrated that HBV genome-derived dsDNA induced the innate immune response through cGAS and its adaptor protein, STING, in human hepatoma Li23 cells expressing high levels of cGAS. In addition, we demonstrated that HBV infection induced ISG56 through the cGAS-STING signaling pathway. This signaling pathway also showed an antiviral response towards HBV through the suppression of viral assembly. From these results, we conclude that the cGAS-STING signaling pathway is required for not only the innate immune response against HBV but also the suppression of HBV assembly. The cGAS-STING signaling pathway may thus be a novel target for anti-HBV strategies. en-copyright= kn-copyright= en-aut-name=DansakoHiromichi en-aut-sei=Dansako en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UedaYouki en-aut-sei=Ueda en-aut-mei=Youki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkumuraNobuaki en-aut-sei=Okumura en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatohShinya en-aut-sei=Satoh en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiyamaMasaya en-aut-sei=Sugiyama en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MizokamiMasashi en-aut-sei=Mizokami en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoNobuyuki en-aut-sei=Kato en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Research Center for Hepatitis and Immunology, National Center for Global Health and Medicine affil-num=6 en-affil= kn-affil=Research Center for Hepatitis and Immunology, National Center for Global Health and Medicine affil-num=7 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry affil-num=8 en-affil= kn-affil=Department of Tumor Virology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences en-keyword=Antiviral response kn-keyword=Antiviral response en-keyword=hepatitis B virus kn-keyword=hepatitis B virus en-keyword=innate immune response kn-keyword=innate immune response en-keyword=cGAS-STING signaling pathway kn-keyword=cGAS-STING signaling pathway en-keyword=viral assembly kn-keyword=viral assembly END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=606 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20131113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of rhizosphere, rhizoplane and phyllosphere bacteria and fungi isolated from rice in Kenya for plant growth promoters en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice (Oryza sativa L.) is the most important staple food crop in many developing countries, and is ranked third in Kenya after maize and wheat. Continuous cropping without replenishing soil nutrients is a major problem in Kenya resulting to declining soil fertility. The use of chemical fertilizers to avert the problem of low soil fertility is currently limited due to rising costs and environmental concerns. Many soil micro-organisms are able to solubilize the unavailable phosphorus, increase uptake of nitrogen and also synthesize growth promoting hormones including auxin. The aim of this study was to isolate and characterize phyllosphere, rhizoplane and rhizosphere micro-organisms from Kenyan rice with growth promoting habits. In this study whole plant rice samples were collected from different rice growing regions of Kenya. 76.2%, over 80% and 38.5% of the bacterial isolates were positive for phosphate solubilization, nitrogenase activity and IAA production whereas 17.5% and 5% of the fungal isolates were positive for phosphate solubilization and IAA production respectively. Hence these micro-organisms have potential for utilization as bio-fertilizers in rice production. en-copyright= kn-copyright= en-aut-name=Rashid MwajitaMwashasha en-aut-sei=Rashid Mwajita en-aut-mei=Mwashasha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurageHunja en-aut-sei=Murage en-aut-mei=Hunja kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaniAkio en-aut-sei=Tani en-aut-mei=Akio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KahangiEsther M en-aut-sei=Kahangi en-aut-mei=Esther M kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Kenya Agricultural Research Institute affil-num=2 en-affil= kn-affil=Jomo Kenyatta University of Agriculture and Technology affil-num=3 en-affil= kn-affil=Institute of Plant Science and Resources Okayama University affil-num=4 en-affil= kn-affil=Jomo Kenyatta University of Agriculture and Technology en-keyword=Micro-organisms kn-keyword=Micro-organisms en-keyword=Phosphate solubilization kn-keyword=Phosphate solubilization en-keyword=Nitrogen fixation kn-keyword=Nitrogen fixation en-keyword=IAA production kn-keyword=IAA production END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=培養法および非培養法によるアルファルファサイレージの嫌気的貯蔵および好気的変敗に関わる微生物フローラの解析 kn-title=Culture-dependent and culture-independent analysis of microbiota associated with anaerobic storage and aerobic deterioration of alfalfa silage en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WuBaiyila en-aut-sei=Wu en-aut-mei=Baiyila kn-aut-name=呉白乙拉 kn-aut-sei=呉 kn-aut-mei=白乙拉 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院 END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=2 article-no= start-page=71 end-page=78 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Annexin A1 Negatively Regulates Viral RNA Replication of Hepatitis C Virus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Persistent infection with hepatitis C virus (HCV) often causes chronic hepatitis, and then shows a high rate of progression to liver cirrhosis and hepatocellular carcinoma. To clarify the mechanism of the persistent HCV infection is considered to be important for the discovery of new target(s) for the development of anti-HCV strategies. In the present study, we found that the expression level of annexin A1 (ANXA1) in human hepatoma cell line Li23-derived D7 cells was remarkably lower than that in parental Li23 cells, whereas the susceptibility of D7 cells to HCV infection was much higher than that of Li23 cells. Therefore, we hypothesized that ANXA1 negatively regulates persistent HCV infection through the inhibition of viral RNA replication. The results revealed that HCV production was significantly inhibited without a concomitant reduction in the amount of lipid droplets in the D7 cells stably expressing exogenous ANXA1. Further, we demonstrated that ANXA1 negatively regulated the step of viral RNA replication rather than that of viral entry in human hepatocytes. These results suggest that ANXA1 would be a novel target for the development of anti-HCV strategies. en-copyright= kn-copyright= en-aut-name=HiramotoHiroki en-aut-sei=Hiramoto en-aut-mei=Hiroki

drunk habitually since ancient times as a unique drink. It is produced from cow, mare and camel milk by a traditional method using indigenous starter cultures containing lactic acid bacteria, yeasts and other fermentative microorganisms. Spontaneously fermented milk products have for centuries been consumed for their therapeutic value in promoting health and well-being, especially among the pastoral communities in Mongolia. Most traditional fermentations are conducted as uncontrolled processes, however, increasing research, such as that focused on compositional properties and microbial biota properties, offers prospective views for improving spontaneous fermented products with respect to safety, shelf life, sensory characteristics, and nutritional and functional qualities. The aim of this article is to investigate progress in the microbiological research on the traditional alcoholic fermented milk, airag, in Mongolia and to give an outline of the traditional preparation processes. en-copyright= kn-copyright= en-aut-name=MiyamotoTaku en-aut-sei=Miyamoto en-aut-mei=Taku kn-aut-name=宮本拓 kn-aut-sei=宮本 kn-aut-mei=拓 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学農学部 en-keyword=airag kn-keyword=airag en-keyword=alcoholic fermented milk kn-keyword=alcoholic fermented milk en-keyword=lactic acid bacteria kn-keyword=lactic acid bacteria en-keyword=yeasts kn-keyword=yeasts en-keyword=traditional preparation process kn-keyword=traditional preparation process END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue= article-no= start-page=5 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20150201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=好酸性鉄酸化細菌 Acidithiobacillus ferrooxidans の染色体凝集・分配タンパク質（ScpB）の性質 kn-title=Characterization of a putative chromosome segregation and condensation protein (ScpB) in an acidophilic iron‒oxidizing bacterium Acidithiobacillus ferrooxidans en-subtitle= kn-subtitle= en-abstract=　Acidithiobacillus ferrooxidans は，低品位の銅鉱石から銅を回収するバイオリーチングにおいて使用される微生物 の一つである．この細菌は，エネルギー源として二価鉄イオンや還元型無機硫黄化合物（RISC）を使用する．鉄の酸化に関与する遺伝子の転写は，A. ferrooxidans が RISC で生育したときには抑制されるが，RISC の酸化に関与すると考えられている遺伝子の転写は活性化されることが知られている．硫黄やテトラチオン酸で生育したときにその発現が上方制御される硫化水素：キノン酸化還元酵素のすぐ上流に，ヘリックスターンへリックスモティーフを持つ，ScpB と推定されるタンパク質をコードする遺伝子が存在していた．鉄，硫黄，テトラチオン酸生育細胞から調製した cDNA を用いた半定量的 PCR 分析の結果，硫黄やテトラチオン酸で生育した細胞内の scpB 遺伝子の転写は，鉄生育細胞と比較すると上方制御されていた．組換え ScpB タンパク質を用いたゲルシフトアッセイ法で，ScpB が転写制御因子として機能するかどうかを調べた．その結果，ScpB は DNA に結合したが，結合の特異性はなかった．ScpB が直接 DNA と相互作用する報告はこれまでになかった． kn-abstract=　Acidithiobacillus ferrooxidans is one of the most widely used microorganisms in bioleaching operations to recover copper from low-grade copper sulfide. This bacterium uses ferrous iron and reduced inorganic sulfur compounds (RISCs) as energy sources. Transcriptions of genes thought to be involved in the oxidation of RISCs have been known to be highly activated in A. ferrooxidans cells grown on RISCs, while transcriptions of genes involved in the iron oxidation were repressed in the cells grown on RISCs. A gene encoding a putative chromosome segregation and condensation protein (ScpB) with a helix-turn-helix motif was found in the upstream region of sulfide : quinone oxidoreductase gene, whose expression was up-regulated in cells grown in sulfur and tetrathionate. A semi-quantitative PCR analysis using cDNA prepared from iron-, sulfur-, or tetrathionate-grown cells revealed that the transcription of scpB was up-regulated in cells grown on sulfur or tetrathionate as the energy source. Electrophoretic mobility shift assays were employed to examine whether the ScpB functions as a transcription factor. The result indicated that the recombinant His-tagged ScpB protein was able to nonspecifically bind in vitro to DNA. This is the first report on a direct association of ScpB with DNA. en-copyright= kn-copyright= en-aut-name=KamimuraKazuo en-aut-sei=Kamimura en-aut-mei=Kazuo kn-aut-name=上村一雄 kn-aut-sei=上村 kn-aut-mei=一雄 aut-affil-num=1 ORCID= en-aut-name=NagataNozomu en-aut-sei=Nagata en-aut-mei=Nozomu kn-aut-name=長田臨 kn-aut-sei=長田 kn-aut-mei=臨 aut-affil-num=2 ORCID= en-aut-name=KikumotoMei en-aut-sei=Kikumoto en-aut-mei=Mei kn-aut-name=菊本愛生 kn-aut-sei=菊本 kn-aut-mei=愛生 aut-affil-num=3 ORCID= en-aut-name=SharminSultana en-aut-sei=Sharmin en-aut-mei=Sultana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WakaiSatoshi en-aut-sei=Wakai en-aut-mei=Satoshi kn-aut-name=若井暁 kn-aut-sei=若井 kn-aut-mei=暁 aut-affil-num=5 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name=金尾忠芳 kn-aut-sei=金尾 kn-aut-mei=忠芳 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=4 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=5 en-affil= kn-affil=神戸大学自然科学系先端融合研究環 affil-num=6 en-affil= kn-affil=神戸大学自然科学系先端融合研究環 en-keyword=Acidithiobacillus ferrooxidans kn-keyword=Acidithiobacillus ferrooxidans en-keyword=Acidophile kn-keyword=Acidophile en-keyword=ScpB kn-keyword=ScpB en-keyword=transcription factor kn-keyword=transcription factor END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=12 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Nuclear Receptor Genes HR3 and E75 Are Required for the Circadian Rhythm in a Primitive Insect en-subtitle= kn-subtitle= en-abstract= kn-abstract=Insect circadian rhythms are generated by a circadian clock consisting of transcriptional/translational feedback loops, in which CYCLE and CLOCK are the key elements in activating the transcription of various clock genes such as timeless (tim) and period (per). Although the transcriptional regulation of Clock (Clk) has been profoundly studied, little is known about the regulation of cycle (cyc). Here, we identify the orphan nuclear receptor genes HR3 and E75, which are orthologs of mammalian clock genes, Rorα and Rev-erbα, respectively, as factors involved in the rhythmic expression of the cyc gene in a primitive insect, the firebrat Thermobia domestica. Our results show that HR3 and E75 are rhythmically expressed, and their normal, rhythmic expression is required for the persistence of locomotor rhythms. Their RNAi considerably altered the rhythmic transcription of not only cyc but also tim. Surprisingly, the RNAi of HR3 revealed the rhythmic expression of Clk, suggesting that this ancestral insect species possesses the mechanisms for rhythmic expression of both cyc and Clk genes. When either HR3 or E75 was knocked down, tim, cyc, and Clk or tim and cyc, respectively, oscillated in phase, suggesting that the two genes play an important role in the regulation of the phase relationship among the clock genes. Interestingly, HR3 and E75 were also found to be involved in the regulation of ecdysis, suggesting that they interconnect the circadian clock and developmental processes. en-copyright= kn-copyright= en-aut-name=KamaeYuichi en-aut-sei=Kamae en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UryuOuta en-aut-sei=Uryu en-aut-mei=Outa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MikiTaiki en-aut-sei=Miki en-aut-mei=Taiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Department of Biology, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=227 end-page=230 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Molecular target therapies in rheumatic diseases kn-title=リウマチ性疾患における分子標的治療 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=WakabayashiHiroshi en-aut-sei=Wakabayashi en-aut-mei=Hiroshi kn-aut-name=若林宏 kn-aut-sei=若林 kn-aut-mei=宏 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　腎・免疫・内分泌代謝内科学 en-keyword=リウマチ性疾患 kn-keyword=リウマチ性疾患 en-keyword=自己免疫疾患 kn-keyword=自己免疫疾患 en-keyword=生物学的製剤 kn-keyword=生物学的製剤 en-keyword=分子標的薬 kn-keyword=分子標的薬 END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=209 end-page=215 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hospital and clinic cooperation for the treatment of rheumatoid arthritis in Okayama Prefecture, Japan kn-title=岡山県下のクリニック・診療所におけるリウマチ診療・病診連携の実態に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: To survey the current status and problems of cooperation between clinics and hospitals in Okayama Prefecture, Japan for the treatment of rheumatoid arthritis (RA). 　Methods: We distributed a questionnaire to 300 of the 983 Okayama Prefecture clinics that had either an internal medicine or orthopedic surgery department, from December 2013 to February 2014. The questionnaire covered practice pattern for RA treatment in clinics, current status of the hospital and clinic cooperation, and acceptance of the biologic therapy. 　Results: One hundred clinics responded to the questionnaire. Seventy percent of the clinics reported making referrals to rheumatologists before the initiation of RA treatment, and half of the other 30% of the clinics administered methotrexate as the first-line treatment for RA by their own decision. Sixty-six clinics cooperated with flagship hospitals, conducting medical and laboratory examinations, providing prescriptions, and treating common diseases of patients. These clinics expected the cooperating rheumatologists to follow-up patients every 3 to 6 months and to make the diagnosis, make decisions regarding RA treatment changes, and perform surgery. Seventy-one percent of the clinics responded that cooperation with a hospital is possible even for patients who are administered biologics. As reasons for no cooperation with the flagship hospitals, clinics noted the lack of information about rheumatologists in the area and recent trends in the management of RA. 　Conclusion: The current study reported, for the first time, the actual conditions of management of RA in clinics, as well as future problems of hospital and clinic cooperation in Okayama Prefecture. en-copyright=

crystal displays was assessed with a battery of four selected acute toxicity bioassays. We focused on tetramethylammonium hydroxide (TMAH, CAS No. 75-59-2), a widely utilized etchant. The toxicity of TMAH was low when tested in the 72 h-algal growth inhibition test (Pseudokirchneriellia subcapitata, EC50 = 360 mg L−1) and the Microtox® test (Vibrio fischeri, IC50 = 6.4 g L−1). In contrast, the 24 h-microcrustacean immobilization and the 96 h-fish mortality tests showed relatively higher toxicity (Daphnia magna, EC50 = 32 mg L−1 and Oryzias latipes, LC50 = 154 mg L−1). Isobologram and mixture toxicity index analyses revealed apparent synergism of the mixture of TMAH and potassium iodide when examined with the D. magna immobilization test. The synergistic action was unique to iodide over other halide salts i.e. fluoride, chloride and bromide. Quaternary ammonium ions with longer alkyl chains such as tetraethylammonium and tetrabutylammonium were more toxic than TMAH in the D. magna immobilization test. en-copyright= kn-copyright= en-aut-name=MoriIzumi C. en-aut-sei=Mori en-aut-mei=Izumi C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Arias-BarreiroCarlos R. en-aut-sei=Arias-Barreiro en-aut-mei=Carlos R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoutsaftisApostolos en-aut-sei=Koutsaftis en-aut-mei=Apostolos kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgoAtsushi en-aut-sei=Ogo en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoTomonori en-aut-sei=Kawano en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshizukaKazuharu en-aut-sei=Yoshizuka en-aut-mei=Kazuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=Inayat-HussainSalmaan H. en-aut-sei=Inayat-Hussain en-aut-mei=Salmaan H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AoyamaIsao en-aut-sei=Aoyama en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=2 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=3 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=4 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University affil-num=5 en-affil= kn-affil=School of International Environmental Science, The University of Kitakyushu affil-num=6 en-affil= kn-affil=School of International Environmental Science, The University of Kitakyushu affil-num=7 en-affil= kn-affil=Faculty of Health Sciences, Univerisiti Kebangsaan Malaysia affil-num=8 en-affil= kn-affil=Institute of Plant Science and Resources, Okayama University en-keyword=Tetramethylammonium hydroxide kn-keyword=Tetramethylammonium hydroxide en-keyword=Potassium iodide kn-keyword=Potassium iodide en-keyword=Aquatic toxicity kn-keyword=Aquatic toxicity en-keyword=Synergism kn-keyword=Synergism en-keyword=D. magna kn-keyword=D. magna en-keyword=Semiconductor wastewater kn-keyword=Semiconductor wastewater END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=2 article-no= start-page=127 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Fermented persimmon extract (kaki-shibu) is useful as a standard for component analyses of persimmon phytobezoars kn-title=柿胃石の成分分析における標準物質としての柿渋の有用性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The definite diagnosis of persimmon phytobezoar (i.e., diospyrobezoar) is often accomplished by a component analysis using infrared spectroscopy. However, no studies have been conducted to investigate which substance is the best as a standard for the component analysis. Here we analyzed tannic acid, Japanese persimmon (kaki), fermented persimmon extract (kaki-shibu), conventional dried persimmon, and dried persimmon smoked in sulfur (ampo-kaki) by infrared spectroscopy to determine which would be optimal as a component analysis standard. The spectrum between 1,600 to 600cm－1 of a persimmon phytobezoar was quite similar to the spectrum of kaki-shibu rather than that of tannic acid. Consequently, we conclude that kaki-shibu should be used as a standard for infrared spectroscopy analyses of persimmon phytobezoars. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya
