摘　　要：株高是水稻的重要农艺性状之一。研究表明,半矮化有利于水稻的抗倒伏与丰产性能,并且与赤霉素合成基因SD1突变有关,因此推测激素是调控株高的重要因素,阐明激素在植物内的合成代谢途径及其信号转导途径具有重要意义。本研究综述了赤霉素(gibberellin acids, GAs)、脱落酸(abscisic acid, ABA)、油菜素甾醇(brassinosteroids, BRs)三种主要植物激素在水稻中的合成代谢途径及其信号转导途径,以及其在调控水稻株高方面的研究进展,以期为水稻品种改良提供新的信息和线索。Plant height is one of the important agronomic traits of rice(Oryza sativa L.). Researches showed that semi-dwarfing is beneficial to the lodging resistance and high yield properties, and is associated with the mutation of gibberellin acids(GA) synthetic gene SD1. Therefore, it's speculated that phytohormone is a vital factor to regulate plant height, and it is important to clarify the anabolic pathways and signal transduction pathways of hormones in plant. This study reviewed the anabolic pathway and signal transduction pathways of three major phytohormones(GAs, ABA and BRs) in rice and the recent progress of these hormones in regulating rice plant height,which would provide new information and clues for rice improvement.
