水稻幼穗-颖花发育的研究进展

Research Advancement on Young Panicle and Spikelet Development in Rice(Oryza sativa L.)

水稻是世界上最重要的粮食作物之一,也是单子叶植物发育生物学研究的理想模式植物,水稻幼穗和颖花的发育还是最终产量赖以依托的基础。对水稻幼穗和颖花发育的研究已成为植物分子遗传学和作物科学共同的研究焦点。近年来,有关水稻幼穗和颖花发育的研究取得了长足的进展,本文对幼穗和颖花的发育过程、栽培措施和环境因子对幼穗和颖花发育的影响以及幼穗和颖花发育的相关基因等方面的国内外进展进行了综述,同时指出了目前研究中存在的问题及相应的研究对策。

Rice,one of the world＇s most important food crops,is a model plant for developmental biology re- search of the grasses. Development status of rice young panicle and spikelet determines final yield. So, the research on developmental biology of young panicle and spikelet has been the same focus in plant molecular genetics and crop sci- ence. The developmental biology related to young panicle and spikelet has achieved a series of great advances in re- cent years. The present paper reviewed their developmental process, effects of cultural practices and environmental fac- tors and related genes. And the problems and countermeasures in present research were also been discussed.
