Japan-French joint study in plant physiology based ongenome

本研究是与具有丰富研究经验的日本和法国的研究人员合作，利用拟南芥、水稻等植物的各种基因组信息和许多突变体，研究高等植物中的一些重要生理问题。本项目的主要研究对象是胚胎发生、维管形成、成花诱导、自交不亲和性等，特别是细胞分裂、细胞结构、细胞死亡等作为植物个体生理反应功能基础的细胞事件，以及调节植物激素（生物合成和信号转导）、生物钟等现象的组分。此外，考虑到两国在转基因植物方面的实际问题，还对转基因作物、产生有用次生代谢物的转基因植物、植物修复用转基因植物等转基因植物的研究进行了探讨，因为这些研究具有实用价值， 关于我们 在1999年至2001年的3年时间里，该项目取得了以下研究成果：编码脱落酸（阿坝）生物合成限速酶的基因的分离和表征，控制阿坝信号转导的因子的分离和表征，胚胎特异性基因的分离、鉴定及其表达机制、植物激素与植物生长发育的关系（生长素、细胞分裂素和油菜素类固醇）诱导基因和生理现象，鉴定控制胚胎发生、维管形成、开花的光周期诱导和其它形态发生的遗传程序中的主要因子，一种检测转基因作物的新方法等。2001年秋，在法国举行了日法研讨会，参加该项目的日本和法国的许多研究人员参加了研讨会，讨论了他们的研究成果，并就日本和法国在植物生理学方面的未来合作进行了磋商。少

This research had been conducted to study some important physiological problems in higher plants, in collaboration of researchers of Japan and France who had many research experience in their collaboration, using various genome information and many mutants of Arabidopsis, rice and other plants. Main subjects in this project were embryogenesis, vascular formation, flower induction, self-incompatibility, and others, especially cellular events like cell division, cell structure, cell death and others which are functional base of physiological responses in individual plants, and components regulating the phenomena like phytohormones (biosynthesis and signal transduction), biological clock and others. Moreover, studies on transgenic plants like transgenic crops, transgenic plants producing useful secondary metabolites, transgenic plants for phytoremediation were also investigated as considering practical problems on the genetically modified plants in both countries, because these applied re … More searches are carrying out in the world based on basic research which were main subjects in this projectDuring 3 years from 1999 to 2001, many research outcomes were obtained in this project as follows ; isolation and characterization of a gene encoding a rate limiting enzyme of abscisic acid (ABA) biosynthesis, isolation and characterization of factors controlling ABA signal transduction, isolation and characterization of embryo-specific genes and the mechanisms of its gene expression, relation between phytohormone (auxin, cytokinin and brassinosteroid)-inducible genes and physiological phenomena, identification of main factors in genetic program controlling embryogenesis, vascular formation, photoperiodic induction of flowering, and other morphogenesis, a new method for detection of transgenic crops, and others. In the autumn of 2001, Japan-French workshop was held in France and many researchers of Japan and France who participated in this project attended it, discussed on their research outcomes and consulted the future collaborative works between Japan and France in plant physiology.
