The function of the living matter from biomolecules to the whole body of the organism is based on the structure. Consequently, structural information is essential for the understanding of the function of living organisms. The biological structures from biomolecules to cells and tissues are intimately related to each other, and changing their morphological,(More)
Efficient production of carbon-neutral biofuels is key to resolving global warming and exhaustion of fossil fuels. Cellulose, which is the most abundant biomass, is physically strong and biochemically stable, and these characteristics lead to difficulty of efficient saccharification of cellulosic compounds for production of fermentable glucose and other(More)
Organisms are covered extracellularly with cuticular waxes that consist of various fatty acids. In higher plants, extracellular waxes act as indispensable barriers to protect the plants from physical and biological stresses such as drought and pathogen attacks. However, the effect of fatty acid composition on plant development under normal growth conditions(More)
We generated transgenic rice plants that express EXG1 exo-glucanase under the control of a senescence-inducible promoter. When a GUS coding sequence was connected to a promoter region of STAY GREEN (SGR) gene of rice and introduced into rice, GUS activity was specifically observed along with senescence. When an EXG1 cDNA was connected to the SGR promoter(More)
Maintenance of organ separation is one of the essential phenomena for normal plant development. We have identified and analyzed ONION3 (ONI3), which is required for avoiding organ fusions in rice. Loss-of-function mutations of ONI3, which were identified as mutants with ectopic expression of KNOX genes in leaves and morphologically resembling KNOX(More)
The pollen function of cytoplasmic male sterile (CMS) plants is often recovered by the Restorer of fertility (Rf) gene encoded by the nuclear genome. An Rf gene of Lead rice type CMS, Rf2, encodes a small mitochondrial glycine-rich protein. RF2 is expected to function by interacting with other proteins, because RF2 has no motifs except for glycine-rich(More)
