摘要/Abstract

摘要： 株高是水稻的重要农艺性状。近年来，随着分子生物学技术的不断改进和提高，许多以往报道的和新发现的水稻株高基因得到了克隆，并进行了深入的功能研究。研究结果表明，激素在水稻株高发育中起主要调控作用，尤其以赤霉素、油菜素内酯和独脚金内酯三类激素的作用最大。调控过程涉及到激素的合成与信号途径，以及激素之间的互作。同时也存在其他调控途径，表明水稻株高形态建成是一个复杂的生理过程。以水稻株高基因功能的介绍为要点，回顾了近年来国内外在该领域的研究进展。

Abstract: Plant height is an important agronomic trait in rice. In recent years, with the continuous improvement of molecular biology techniques, many previously reported and newly identified rice plant height genes have been cloned, and conducted in-depth functional studies. The results indicated that hormones had been playing key roles in regulating rice plant height, while gibberellin, brassinosteroid and strigolactones having the greatest effect. The regulation process involved hormone synthesis and signaling pathways and interactions between hormones. Meanwhile, other regulatory pathways also existed, which showed that rice plant height morphogenesis was a complex physiological process. This paper places functions of rice plant height genes as the priority, and introduces the research progress on this area in recent years at home and abroad.
