摘要
植物激素是指植物通过自身代谢产生的,在很低浓度下就能产生明显生理效应的一些有机信号分子,在植物生长发育及环境响应过程中具有至关重要的作用.中国科学家利用植物组织离体培养、以突变体为主导的分子遗传学手段及以水稻农艺性状为核心的植物激素研究策略,在植物激素的生理功能、生物合成及代谢、信号感知及传导等方面均取得了较大的成就,较好地推动了植物激素的理论研究及生产应用.本文主要总结了我国科学家在生长素、细胞分裂素、油菜素甾醇、赤霉素、乙烯、脱落酸、茉莉素、水杨酸、独脚金内酯及多肽激素研究中取得的重要进展,以此来启发并激励我国年轻一代植物学家能在植物激素研究中取得更多具有原始创新性的研究成果.
Plant hormones are naturally occurring organic signaling molecules, playing central roles in coordinating almost every aspect of plant growth, development and stress adaptations at vanishingly low concentrations. Plant hormones often synthesize in one cell/tissue and function in a different cell/tissue. Within the last seventy years, Chinese scholars have made significant contributions to our better understanding the biological functions, biosynthesis, catabolism, cross-talks, and signal transduction of plant hormones through a number of distinctive approaches such as tissue culture, mutant analysis, and identification of altered agronomic traits in rice and other crops under various growing conditions. The knowledge obtained from these studies will be used to improve crop productivities and stress adaptions in the future. In this review article, we are trying to put together some of the major discoveries made by Chinese scholars in ten major groups of plant hormones, including auxin, cytokinins, brassinosteroids, gibberellins, ethylene, abscisic acid,jasmonates, salicylic acid, strigolactones, and peptides. This review is written in Chinese, our purpose is to provide a reference to our undergraduate and graduate students.
