摘　　要：颖花是水稻的繁殖器官和形成籽粒的基础,其正常发育直接影响稻谷产量和稻米品质。因此,研究水稻颖花发育的分子调控机理,对于水稻发育的基础理论研究和农业育种具有重要的意义。近年来的研究结果表明茉莉素、生长素和表观遗传在水稻颖花发育中具有重要的调控作用。综述了茉莉素、生长素和表观遗传在调控水稻颖花的产生和形态建成等方面的最新研究进展,并提出未来研究需要分离更多相关基因以充实水稻颖花发育调控网络,促进其分子机制的解析。The floret are the reproductive organs of rice and the basis of grain formation,and their normal development directly affects the yield and quality of rice.Therefore,it is of great significance to study the molecular regulation mechanism of rice floret development for the basic theoretical research of rice development and agricultural breeding.The research results in recent years have shown that jasmonates,auxin and epigenetics have important regulating effect in rice floret development.In this paper,the recent research progress in the regulation of jasmonates,auxin and epigenetics on the production of rice floret and their morphogenesis were reviewed,and it was suggested that more related genes should be isolated in further studies,thus to enrich the regulatory network of rice floret development and promote the analysis of their molecular mechanisms.
