摘要: 随着水稻高产相关基因的克隆与功能分析,调控水稻产量的分子机理逐渐被人们了解与解读。株型控制由基因IPA1及4个直接控制分蘖的基因来共同完成。已报道的与穗发育相关的基因有11个,其中3个基因参与穗分化基本生物学过程,6个基因参与调控籽粒分化比率,2个基因参与调控穗分化期。控制水稻粒型和粒重的基因有5个,分别参与籽粒长、籽粒宽和灌浆过程。水稻产量基因的克隆与解读为水稻高产育种提供了理论指导。

Abstract: With a large number of genes contributed to high\|yield in rice had been mapped and cloned, the molecular mechanism underlying yield traits has been gradually understood in rice. IPA1 gene and four other genes directly controlling tiller development were cooperated with each other for conferring the plant architecture traits. Up to now, it was reported that 11 genes participated in the panicle formation, 3 of which were involved in the basic biological processes in panicle development, while 6 genes regulated the rate of spikelet formation, and 2 genes regulated the duration of panicle differentiation. Genes for determination of grain size or grain weight had five members, which were involved in grain length, grain width and the filling of grain, respectively. Cloning and understanding the molecular nature of genes controlling rice yield traits may be a fundamental implication for rice genetic improvements.
