| Abstract | To establish a proposal for a guiding principle supporting appropriate management of Iris pseudacorus L., which had been used as an important vegetation bank species until the Invasive Alien Species Act, this study investigated propaga-tion characteristics. The seed in which seed coat cracked germinated earlier, and it was shown that their cumulative germination percentage was high even under 30 °C constant conditions. When the fresh weight of the rhizome cut pieces in the spring became greater than 15 g, the individual plant flowering rate increased gradually. Individuals of more than 30 g achieved a flowering rate higher than 76 %. The flow-ering rate was highest for individual plants that had two green leaves, but it became progressively lower for increas-ing numbers of green leaves：non-flowering individuals grew better than flowering individuals. In the 0 cm height scape-cutting treatment, no significant difference was found in the numbers of flowers and fruits the next year. In the 5 cm height top-cutting treatment, the flowers and fruits in the next year were significantly fewer. |

| Title Alternative | Big data in the sex chromosomes of Silene plants and a fungus acting as a plant sex chromosome |

| Abstract | Silene latifolia (Caryophyllaceae) is a dioecious plant that has long been used for study on sex chromosomes in plants. The advantage but also disadvantage of S. latifolia as a model system is the size of the Y chromosome that contains an extremely large male-specific region (approx. > 500 Mb). This feature implies that the evolutionary history of sex chromo-somes remains in the S. latifolia Y chromosome, while the size makes analyses esoteric. Another advantage is that plants in the genus Silene show variation in reproductive systems; most are gynodioecy (females and hermaphrodites), which is thought of as an evolutionary status before establishment of dioecy (males and females), with a few hermaphrodites and dioecy, suggesting that the genus Silene may represent an epitome of the sex chromosome evolution. Microbotryum is a biotrophic fungi, whose infection causes masculinization of the female flower, as if the fungus acts as the Y chromo-some. Though the underlying molecular mechanisms remain unknown, recent high-throughput sequence technologies provide many candidate genes for sex determination in plants and sex conversion by the fungus. In this article, I review and introduce studies of the Y chromosome in S. latifolia plant, the evolution of sex chromosomes in the genus Silene, the masculinization of female flowers caused by a fungus infection, and a virus vector that can be used for genetic analysis of the key genes involved in these processes. |

| Title Alternative | Studies on antitumor enzyme l-lysine α-oxidase from Trichoderma viride |

| Abstract | L-Lysine α-oxidase (LysOX) from Trichoderma viride is a homodimeric flavoenzyme that catalyzes the oxidative deamination of L-Lysine to produce α-keto-ε-aminocaproate with ammonia and hydrogen per-oxide. LysOX inhibited the growth of cancer cells but showed relatively low toxicity for normal cells. The full-length cDNA consists of 2,119 bp, and encodes a long N-terminal propeptide composed of 77 resi-dues (Met1-Arg77) and the mature protein (Ala78-Ile617). The LysOX gene was heterologously expressed in Streptomyces lividans TK24 or Escherichia coli SoluBL21. The enzymatic properties of the purified recombinant LysOX, such as substrate specificity, kinetic parameters and thermal stability, are the same as those of the native LysOX. The LysOX precursor (prLysOX) expressed in E. coli shows weak enzymatic activity and is activated by proteolytic processing. The crystal structure of prLysOX revealed that the propeptide of prLysOX indirectly changes the active site structure to inhibit enzyme activity. Moreover, the crystal structures of LysOX and its L-Lysine complex revealed that the hydrogen bonding network formed by Asp212, Asp315 and Ala440 with two water molecules is responsible for the recogni-tion of the ε-amino group of L-Lysine. In addition, a narrow substrate-binding site and acidic surface at the active site entrance both contribute to strict substrate specificity. Mutational analysis demonstrated that Asp212 and Asp315 are essential for substrate recognition, and the D212A/D315A LysOX prefers aromatic amino acids. Furthermore, the structural basis of the substrate specificity change has also been revealed by the structural analysis of the D212A/D315A LysOX and its substrate complexes. |

| Abstract | In Eustoma (Eustoma grandiflorum (Raf.) Shinn) cultivation in southwestern Japan, cold imbibition treatment of seeds is important to accelerate bolting and flowering of seedlings grown in the summer season. In order to facilitate the handling of cold imbibed seeds, re-drying treatment (RDT) after wet treatment at 10°C for 35 days in dark conditions (WT10°C) is considered to be an essential technique. The investigation of five Eustoma cultivars ‘Exe Lavender’, ‘Orb Snow’, ‘Philia Lavender’ , ‘Dure Lavender’ and ‘Exe Light Pink’ was to find the germinability and the growth characteristics of Eustoma when re-drying and storage at 10°C for 30 days were applied immedietely after ending the WT10°C. The results showed that germination and growth responses differed among Eustoma cultivars. RDT seeds and non- RDT seeds of ‘Exe Lavender’, ‘Orb Snow’ and ‘Philia Lavender’ had a similar germination rate. However, germination rate of RDT seeds in ‘Dure Lavender’ and ‘Exe Light Pink’ was lower than that of non-RDT seeds. There was no significant difference in cut-flower quality grown from RDT and non-RDT among ‘Exe Lavender’, ‘Orb Snow’ and ‘Dure Lavender’. However, bolting and flowering rate of RDT in ‘Dure Lavender’ and ‘Exe Light Pink’ were lower than those of non-RDT. This suggested that it might not be useful to apply RDT after the cold-wet treatment of Eustoma seed due to lower germination or bolting rates in some cultivars. Further investigation of cold-wet exposure and dehydrating conditions is required to establish RDT procedures for Eustoma cultivars. |

| Abstract | Physical memory capacity has increased owing to large-scale integration. In addition, memory footprints have increased in size, as multiple programs are executed on a single computer. Many operating systems manage physical memory by paging a 4 KB page. Therefore, the number of entries in the virtual address translation table for virtual to physical increases along with the size of the memory footprints. This cause a decrease in the translation lookaside buffer (TLB) hit ratio, resulting in the performance degradation of the application. To address this problem, we propose the implementation of physical memory management with two page sizes: 4 KB and 4 MB. This allows us to expand range of addresses to be translated by a single TLB entry, thereby improving the TLB hit rate. This paper describes the design and implementation of the physical memory management mechanism that manages physical memory using two page sizes on The ENduring operating system for Distributed EnviRonment (Tender OS). Our results showed that when the page size is 4 MB, the processing time of the memory allocation can be reduced by as much as approximately 99.7%, and the processing time for process creation can be reduced by as much as approximately 51%, and the processing time of the memory operation could be reduced by as much as 91.9%. |

| Abstract | To handle information leaks caused by administrative errors or mishandling, a function for tracing the diffusion of classified information using a virtual machine monitor (VMM) was proposed. However, the proposed function has not been investigated in cases in which virtual machines (VMs) allocated by multiple virtual central processing units (vCPUs) are to be monitored. In addition, cases in which multiple VMs are monitored have not been examined. In this study, we describe the support of multiple VMs for the proposed VMM-based tracing function. We also show how to deal with VMs allocated by multiple vCPUs. Furthermore, we report the evaluation results from assessing the traceability of the improved proposed method and its overhead for classified information when a VM with multiple vCPUs is monitored. |
