| Abstract | Sexual polymorphism, a main strategy to maintain genetic diversity within a species, has long been a major focus in biology. Notwithstanding, in plants, evolution of sexual systems and mechanisms underlying these transitions have been little unveiled. We have elucidated the molecular mechanism of sex determination in persimmons (Diospyros spp.), where the Y-encoded smRNA gene OGI can repress the female-determining gene MeGI, and also in kiwifruits (Actinidia spp.), where the Y-encoded two sex determinants, Shy Girl and Friendly Boy, control gynoecium and androecium development, respectively. Although the molecular functions of these determinants are distinct, they have common evolutionary scenarios involving transitions of sexual systems. In persimmon, a recent genome triplication (hexaploidization) in cultivated persimmon (D. kaki) derived “flexible” sexuality via establishing epigenetic layers on the two sex determinants. On the other hand, an ancient Diospyros-specific paleo-genome duplication (paleo-tetraploidization) enabled neofunctionalization in the proto-MeGI, via positive selection, to establish a new function as a sex determinant. In kiwifruit, one of the two sex determinants, Shy Girl, was derived from neofunctionalization via Actinidia-specific duplication event. These findings exemplify how plant-specific numerous duplication events can drive flexible genetic material whose variation can be selected for development of new sexual systems. |

| Title Alternative | Development of Effective Biological Treatment Process for Acid Mine Drainage |

| Author | Kamimura, Kazuo| Kanao, Tadayoshi| |
| 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. |

| Title Alternative | Mathematical analysis of copy number variation of 2 μ-based plasmids in yeast cells |
|---|---|
| FullText URL | srfa_109_007_011.pdf |
| Author | Saeki, Nozomu| Moriya, Hisao| |
| Abstract | Plasmids with the 2 μ plasmid origin are commonly-used in the genetic engineering of the budding yeast Saccharomyces cerevisiae. Intracellular copy numbers of 2 μ plasmids are different depending on the genes inserted into the plasmids. This difference is thought to occur from the difference in the growth efficiency （fitness） produced by the positive- and negative-selection biases of genes inserted in the plasmid. In this study, we made a mathematical model based on this assumption. Computational simulations of the model validated that copy numbers of the plasmids are rapidly settled depending on the fitness created by the gene on the plasmid. The copy number of a plasmid only contains a bias to keep the plasmid in a single copy became average 20copies per cell when the plasmid is randomly distributed, suggesting that no positive distribution mechanism is required for a plasmid to become multicopy. |

| Title Alternative | Recombinant expression and characterization of quinone-containing novel glycine oxidase from Marinomonas mediterranea |

| Abstract | Novel glycine oxidase (GlyOX) from Marinomonas mediterranea depends on cysteine tryptophilquinone (CTQ) and catalyzes the oxidative deamination of glycine to produce a glyoxylate, ammonia, and hydrogen peroxide. M. mediterranea GlyOX genes (goxA and goxB) were cloned and recombinant GlyOX was heterologously expressed by E. coli. The purification of recombinant GlyOX was carried out by metal affinity and DEAE-Toyopearl 650M column chromatographies. M. mediterranea GlyOX was homotetramic with a molecular mass of 76kDa and showed optimum activity around 30°C and at pH 5.0, and stability below 50°C and between pH 5.0 to 9.0. M. mediterranea GlyOX shows a strict substrate specificity toward glycine, and the Michaelis constant for glycine was 0.5mM. M. mediterranea GlyOX could determine the quantity of glycine in human serum and human blood plasma with high sensitivity. This study revealed the catalytic and structural properties of M. mediterranea GlyOX with high substrate specificity. |
