摘　要：

穗型是水稻株型的重要组成部分之一, 也是影响水稻产量的关键农艺性状之一。穗的形成过程是一个涉及腋生分生组织发育、花序结构建成和籽粒发育的复杂生理生化过程, 是众多基因参与调控的一个复杂有序的网络系统。本文简介了水稻穗发育的一般过程, 总结了近年来同水稻穗发育相关的基因的研究情况, 分类叙述了这些基因调控穗型的机理以及可能存在的相互关系, 讨论了植物激素信号途径的相关基因和miRNA参与调控植物穗发育的机制。

Abstract:

Panicle architecture is an important component in plant architecture in rice (Oryza sativa L); panicle architecture is also a key ingredient that could influence yield. The process of panicle formation involves a se-ries of complicated physiological and biochemical processes including the development of axillary meristems, the establishment of inflorescence and the formation of seeds, panicle formation is a systemic process regulated by many interlinking genes. In this review, the general progress of the development of a rice panicle is intro-duced. Genes that have great influences on panicle development are categorized according to their different reg-ulatory mechanisms. Genes function in the plant hormone signaling pathway may also influence panicle archi-tecture, and miRNA-mediated regulations of panicle development are discussed.

Key words: rice; panicle architecture; axillary meristem; plant hormone signaling pathway; miRNA
