水稻花发育研究进展

迄今为止,双子叶植物花发育模型研究已基本成熟,这些模型在一定程度上也适用于水稻等单子叶植物的研究.目前,已鉴定克隆了部分与水稻花发育相关的基因,如水稻稀穗LAX、PLAI、LHD、FZP、CL、RFL、RAP1A和RAP1B基因以及花器官发育的水稻ABCDE 5类功能基因和花序变异基因包括Lax、Fzp、OsCKX2、Fon1等,促进了人们对水稻花发育机制的进一步了解.但是有关水稻花发育特异基因之间的调控及作用机理尚未清楚,今后需采用以先进的生物技术为手段,通过分离、鉴定更多的水稻花发育突变体基因,深入探讨各个基因的功能及相互作用,最终系统了解水稻花发育调控机理,从而为深人研究单子叶花序发育奠定基础.

Advances in flower development of rice

So far， the development models of flower in dicots have been studied and great progresses have been made. which are also suitable for monocotyledons. At present， some flower development related genes in rice have been cloned， viz.， LAX， PLAI， LHD， FZP， CL， RFL， RAP1A and RAP1B， and ABCDE five type function genes in development of rice floral organ and inflorescence mutant genes including Lax， Fzp， OsCKX2， Fon1， etc.， which make researchers further realize the development mechanism of rice flower. However， the regulation and mechanism of specific genes in flower development of rice are still unknown. Therefore， much mutant genes related to flower development of rice should be isolated and identified through advanced bio-technologies， and their functions and interactions should be further studied to explore regulation mechanism of flower development of rice， which would play important rotes in further research of inflorescence development in monocotyledons.
