Glycosylation of flagellin is essential for bacterial virulence and is also involved in the determination of host specificity. Flagellin glycans from both pathovars were characterized, and common sites of glycosylation were identified on six serine residues (positions 143, 164, 176, 183, 193, and 201). The structure of the glycan at serine 201 (S201) of flagellin from each pathovar was determined by sugar composition analysis, mass spectrometry, and H-1 and C-13 nuclear magnetic resonance spectroscopy. These analyses showed that the S201 glycans from both pathovars were composed of a common unique trisaccharide consisting of two rhamnosyl (Rha) residues and one modified 4-amino-4,6-dideoxyglucosyl (Qui4N) residue, beta-D-Quip4N(3-hydroxy-1-oxobutyl)2Me-(1 -> 3)-alpha-L-Rhap-(1 -> 2)-alpha-L-Rhap. Furthermore, mass analysis suggests that the glycans on each of the six serine residues are composed of similar trisaccharide units. Determination of the enantiomeric ratio of Rha from the flagellin proteins showed that flagellin from P. syringae pv. tabaci 6605 consisted solely Of L-Rha, whereas P. syringae pv. glycinea race 4 flagellin contained both L-Rha and D-Rha at a molar ratio of about 4:1. Taking these findings together with those from our previous study, we conclude that these flagellin glycan structures may be important for the virulence and host specificity of P. syringae. en-copyright= kn-copyright= en-aut-name=TakeuchiKasumi en-aut-sei=Takeuchi en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoHiroshi en-aut-sei=Ono en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaMitsuru en-aut-sei=Yoshida en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshiiTadashi en-aut-sei=Ishii en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatohEtsuko en-aut-sei=Katoh en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaguchiFumiko en-aut-sei=Taguchi en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MikiRyuji en-aut-sei=Miki en-aut-mei=Ryuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MurataKatsuyoshi en-aut-sei=Murata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KakuHanae en-aut-sei=Kaku en-aut-mei=Hanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=National Institute of Agrobiological Sciences affil-num=2 en-affil= kn-affil=National Food Research Institute affil-num=3 en-affil= kn-affil=National Food Research Institute affil-num=4 en-affil= kn-affil=Forestry and Forest Products Research Institute affil-num=5 en-affil= kn-affil=National Institute of Agrobiological Sciences affil-num=6 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University affil-num=8 en-affil= kn-affil=National Institute of Agrobiological Sciences affil-num=9 en-affil= kn-affil=Faculty of Agriculture, Meiji University affil-num=10 en-affil= kn-affil=Graduate School of Natural Science and Technology, Okayama University en-keyword=INNATE IMMUNE-RESPONSE kn-keyword=INNATE IMMUNE-RESPONSE en-keyword=TOLL-LIKE RECEPTOR-5 kn-keyword=TOLL-LIKE RECEPTOR-5 en-keyword=PV.

This region is composed of three open reading frames: orf1, orf2, and orf3. Our previous study revealed that orf1 and orf2 encode glycosyltransferases; on the other hand, orf3 has no role in posttranslational modification of flagellin. Although the function of Orf3 remained unclear, an orf3 deletion mutant (Delta orf3 mutant) had reduced virulence on tobacco plants. Orf3 shows significant homology to a 3-oxoacyl-(acyl carrier protein) synthase III in the fatty acid elongation cycle. The Delta orf3 mutant had a significantly reduced ability to form acyl homoserine lactones (AHLs), which are quorum-sensing molecules, suggesting that Orf3 is required for AHL synthesis. In comparison with the wild-type strain, swarming motility, biosurfactant production, and tolerance to H2O2 and antibiotics were enhanced in the Delta orf3 mutant. A scanning electron micrograph of inoculated bacteria on the tobacco leaf surface revealed that there is little extracellular polymeric substance matrix surrounding the cells in the Delta orf3 mutant. The phenotypes of the Delta orf3 mutant and an AHL synthesis (Delta psyI) mutant were similar, although the mutant-specific characteristics were more extreme in the Delta orf3 mutant. The swarming motility of the Delta orf3 mutant was greater than that of the Delta psyI mutant. This was attributed to the synergistic effects of the overproduction of biosurfactants and/or alternative fatty acid metabolism in the Delta orf3 mutant. Furthermore, the amounts of iron and biosurfactant seem to be involved in biofilm development under quorum-sensing regulation in P. syringae pv. tabaci 6605. en-copyright= kn-copyright= en-aut-name=TaguchiFumiko en-aut-sei=Taguchi en-aut-mei=Fumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaYujiro en-aut-sei=Ogawa en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakeuchiKasumi en-aut-sei=Takeuchi en-aut-mei=Kasumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuzukiTomoko en-aut-sei=Suzuki en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShiraishiTomonori en-aut-sei=Shiraishi en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=4 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=6 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=The Graduate School of Natural Science and Technology, Okayama University en-keyword=TO-CELL SIGNALS kn-keyword=TO-CELL SIGNALS en-keyword=AERUGINOSA kn-keyword=AERUGINOSA en-keyword=FLAGELLIN kn-keyword=FLAGELLIN en-keyword=BIOFILMS kn-keyword=BIOFILMS en-keyword=MOTILITY kn-keyword=MOTILITY en-keyword=IRON kn-keyword=IRON en-keyword=IDENTIFICATION kn-keyword=IDENTIFICATION en-keyword=SIDEROPHORES kn-keyword=SIDEROPHORES en-keyword=SPECIFICITY kn-keyword=SPECIFICITY en-keyword=FLUORESCENT kn-keyword=FLUORESCENT END start-ver=1.4 cd-journal=joma no-vol=48 cd-vols= no-issue=11 article-no= start-page=4283 end-page=4286 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cholera Toxin Production by the El Tor Variant of Vibrio cholerae O1 Compared to Prototype El Tor and Classical Biotypes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio cholerae O1 El Tor variant strains produced much more cholera toxin than did prototype El Tor strains.

The different allelic variants of CS6, caused by point mutations in its structural genes, cssA and cssB, are designated AIBI, AIIBII, AIIIBI, AIBII, and AIIIBII. A simple, reliable, and specific mismatch amplification mutation assay based on real-time quantitative PCR (MAMA-qPCR) was developed for the first time for the detection of CS6-expressing ETEC, along with the identification of allelic variations. The assay was based on mismatched nucleotide incorporation at the penultimate base at the 3' ends of the reverse primers specific for cssA and cssB and was validated using 38 CS6-expressing ETEC isolates. This strategy was effective in detecting all the alleles containing single-nucleotide polymorphisms. Using MAMA-qPCR, we also tested CS6 allelic variants in 145 ETEC isolates from children with acute diarrhea and asymptomatic infections, with the latter serving as controls. We observed that the AIBI and AIIIBI allelic variants were mostly associated with cases rather than controls, whereas the AIIBII variants were detected mostly in controls. In addition, the AIBI and AIIIBI alleles were frequently associated with ETEC harboring the heat-stable toxin gene (est) alone or with the heat-labile toxin gene (elt), whereas the AIIBII allele was predominant in ETEC isolates harboring the elt gene. This study may help in understanding the association of allelic variants in CS6-expressing ETEC with the clinical features of diarrhea, as well as in ETEC vaccine studies. en-copyright= kn-copyright= en-aut-name=SabuiSubrata en-aut-sei=Sabui en-aut-mei=Subrata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DuttaSanjucta en-aut-sei=Dutta en-aut-mei=Sanjucta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DebnathAnusuya en-aut-sei=Debnath en-aut-mei=Anusuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=GhoshAvishek en-aut-sei=Ghosh en-aut-mei=Avishek kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamabataT. en-aut-sei=Hamabata en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=RajendranK. en-aut-sei=Rajendran en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=RamamurthyT. en-aut-sei=Ramamurthy en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NataroJames P. en-aut-sei=Nataro en-aut-mei=James P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SurDipika en-aut-sei=Sur en-aut-mei=Dipika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=LevineMyron M. en-aut-sei=Levine en-aut-mei=Myron M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ChatterjeeNabendu Sekhar en-aut-sei=Chatterjee en-aut-mei=Nabendu Sekhar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=2 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=3 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=4 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=5 en-affil= kn-affil=Natl Ctr Global Hlth & Med affil-num=6 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=7 en-affil= kn-affil=Natl Inst Cholera & Enter Dis affil-num=8 en-affil= kn-affil=Univ Virginia, Sch Med, Dept Pediat affil-num=9 en-affil= kn-affil=Natl Inst Cholera & Enter Dis, Calcutta affil-num=10 en-affil= kn-affil=Univ Maryland, Sch Med, Ctr Vaccine Dev affil-num=11 en-affil= kn-affil=Natl Inst Cholera & Enter Dis END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=5 article-no= start-page=1733 end-page=1736 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development and Evaluation of a PCR Assay for Tracking the Emergence and Dissemination of Haitian Variant ctxB in Vibrio cholerae O1 Strains Isolated from Kolkata, India en-subtitle= kn-subtitle= en-abstract= kn-abstract=A PCR-based assay was developed to discriminate the classical, El Tor, and Haitian types of ctxB alleles.

Discrepancies in the detectability of serum HCV RNA were investigated among 891 consecutive patients who were positive for anti-HCV. Specific nucleotide variations causing the undetectability of HCV RNA were determined and confirmed by synthesizing RNA coding those variations. Serum samples with the discrepancies were also reassessed by CAP/CTM version 2. Among the 891 anti-HCV-positive patients, 4 patients had serum HCV RNA levels that were undetectable by CAP/CTM version 1 despite having levels of > 5 log IU/ml that were detected by ART. All four patients had HCV genotype 2a and high titers of anti-HCV. Sequencing of the HCV 5' noncoding regions revealed 2 common variations, A at nucleotide (nt) 145 and T at nt 151. Synthesized RNAs of the HCV 5' noncoding region with standard (NCR145G151C) and variant nucleotides at nt 145 and nt 151 were quantified with CAP/CTM. RNAs of NCR145G151C and NCR145G151T were quantifiable with CAP/CTM version 1, while those of NCR145A151T and NCR145A151C went undetected. The substitution from G to A at nt 145 specifically conferred this undetectability, while this undetectability was reverted in synthesized HCV RNA with correction of this variation. Reassessment of these samples by CAP/CTM version 2 resulted in similar levels of HCV RNA being detected by ART.

Recent reports indicated the presence of MMPs in the nucleus (A. J. Kwon et al., FASEB J. 18:690-692, 2004); however, its function has not been well investigated. Here, we report a novel function of human nuclear MMP3 as a trans regulator of connective tissue growth factor (CCN2/CTGF). Initially, we cloned MMP3 cDNA as a DNA-binding factor for the CCN2/CTGF gene. An interaction between MMP3 and transcription enhancer dominant in chondrocytes (TRENDIC) in the CCN2/CTGF promoter was confirmed by a gel shift assay and chromatin immunoprecipitation. The CCN2/CTGF promoter was activated by overexpressed MMP3, whereas a TRENDIC mutant promoter lost the response. Also, the knocking down of MMP3 suppressed CCN2/CTGF expression. By cytochemical and histochemical analyses, MMP3 was detected in the nuclei of chondrocytic cells in culture and also in the nuclei of normal and osteoarthritic chondrocytes in vivo. The nuclear translocation of externally added recombinant MMP3 and six putative nuclear localization signals in MMP3 also were shown. Furthermore, we determined that heterochromatin protein gamma coordinately regulates CCN2/CTGF by interacting with MMP3. The involvement of this novel role of MMP3 in the development, tissue remodeling, and pathology of arthritic diseases through CCN2/CTGF regulation thus is suggested. en-copyright= kn-copyright= en-aut-name=EguchiTakanori en-aut-sei=Eguchi en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KubotaSatoshi en-aut-sei=Kubota en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawataKazumi en-aut-sei=Kawata en-aut-mei=Kazumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MukudaiYoshiki en-aut-sei=Mukudai en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeharaJunji en-aut-sei=Uehara en-aut-mei=Junji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhgawaraToshihiro en-aut-sei=Ohgawara en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiAkira en-aut-sei=Sasaki en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KubokiTakuo en-aut-sei=Kuboki en-aut-mei=Takuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakigawaMasaharu en-aut-sei=Takigawa en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Bio-Dental Research Center, Okayama University Dental School kn-affil= affil-num=5 en-affil=Department of Oral & Maxillofacial Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral & Maxillofacial Surgery & Biopathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Oral & Maxillofacial Surgery & Biopathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Oral & Maxillofacial Rehabilitation, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Biochemistry and Molecular Dentistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=3 article-no= start-page=1040 end-page=1045 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Molecular Characterization of High-Level-Cholera-Toxin-Producing El Tor Variant Vibrio cholerae Strains in the Zanzibar Archipelago of Tanzania en-subtitle= kn-subtitle= en-abstract= kn-abstract= Analysis of 1,180 diarrheal stool samples in Zanzibar detected 247 Vibrio cholerae O1, Ogawa strains in 2009.

kn-subject= en-title= kn-title=Hadaka Virus 1: a Capsidless Eleven-Segmented Positive-Sense Single-Stranded RNA Virus from a Phytopathogenic Fungus, Fusarium oxysporum en-subtitle= kn-subtitle= en-abstract= kn-abstract=The search for viruses infecting fungi, or mycoviruses, has extended our knowledge about the diversity of RNA viruses, as exemplified by the discovery of polymycoviruses, a phylogenetic group of multisegmented RNA viruses with unusual forms. The genomic RNAs of known polymycoviruses, which show a phylogenetic affinity for animal positive-sense single-stranded RNA [(+)RNA] viruses such as caliciviruses, are comprised of four conserved segments with an additional zero to four segments. The double-stranded form of polymycovirus genomic RNA is assumed to be associated with a virally encoded protein (proline-alanine-serine-rich protein [PASrp]) in either of two manners: a capsidless colloidal form or a filamentous encapsidated form. Detailed molecular characterizations of polymycoviruses, however, have been conducted for only a few strains. Here, a novel polymyco-related virus named Hadaka virus 1 (HadV1), from the phytopathogenic fungus Fusarium oxysporum, was characterized. The genomic RNA of HadV1 consisted of an 11-segmented positive-sense RNA with highly conserved terminal nucleotide sequences. HadV1 shared the three conserved segments with known polymycoviruses but lacked the PASrp-encoding segment. Unlike the known polymycoviruses and encapsidated viruses, HadV1 was not pelleted by conventional ultracentrifugation, possibly due to the lack of PASrp. This result implied that HadV1 exists only as a soluble form with naked RNA. Nevertheless, the 11 genomic segments of HadV1 have been stably maintained through host subculturing and conidiation. Taken together, the results of this study revealed a virus with a potential novel virus lifestyle, carrying many genomic segments without typical capsids or PASrp-associated forms. IMPORTANCE Fungi collectively host various RNA viruses. Examples include encapsidated double-stranded RNA (dsRNA) viruses with diverse numbers of genomic segments (from 1 to 12) and capsidless viruses with nonsegmented (+)RNA genomes. Recently, viruses with unusual intermediate features of an infectious entity between encapsidated dsRNA viruses and capsidless (+)RNA viruses were found. They are called polymycoviruses, which typically have four to eight dsRNA genomic segments associated with one of the virus-encoded proteins and are phylogenetically distantly related to animal (+)RNA caliciviruses. Here, we identified a novel virus phylogenetically related to polymycoviruses, from the phytopathogenic fungus Fusarium oxysporum. The virus, termed Hadaka virus 1 (HadV1), has 11 (+)RNA genomic segments, the largest number in known (+)RNA viruses. Nevertheless, HadV1 lacked a typical structural protein of polymycoviruses and was not pelleted by standard ultracentrifugation, implying an unusual capsidless nature of HadV1. This study reveals a potential novel lifestyle of multisegmented RNA viruses. en-copyright= kn-copyright= en-aut-name=SatoYukiyo en-aut-sei=Sato en-aut-mei=Yukiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShamsiWajeeha en-aut-sei=Shamsi en-aut-mei=Wajeeha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JamalAtif en-aut-sei=Jamal en-aut-mei=Atif kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BhattiMuhammad Faraz en-aut-sei=Bhatti en-aut-mei=Muhammad Faraz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=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=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=Crop Diseases Research Institute, National Agricultural Research Centre kn-affil= affil-num=4 en-affil=Atta-ur-Rahman School of Applied Biosciences (ASAB), National University of Sciences and Technology (NUST) 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=fungal virus kn-keyword=fungal virus en-keyword=polymycovirus kn-keyword=polymycovirus en-keyword=Fusarium oxysporum kn-keyword=Fusarium oxysporum en-keyword=multisegmented kn-keyword=multisegmented en-keyword=RNA virus kn-keyword=RNA virus en-keyword=capsidless kn-keyword=capsidless en-keyword=neo-virus lifestyle kn-keyword=neo-virus lifestyle END
