| 摘 要： | 植物激素对植物的生长发育有重要的调节作用。由于激素的作用依赖于其浓度, 所以植物内源活性激素的水平必须受到严格控制, 而糖基化修饰被认为是调控激素活性水平的重要方式之一。随着植物激素糖基化修饰相关糖基转移酶基因不断被克隆与鉴定, 多种植物激素的糖基化修饰机制和功能作用逐渐被揭示。该文重点介绍了近年来植物生长素、细胞分裂素、脱落酸、油菜素内酯、水杨酸、茉莉酸等植物激素的糖基转移酶活性鉴定与功能研究进展。同时, 对植物激素糖基化修饰领域存在的问题和发展前景进行了讨论。

| Abstract: | Plant hormones play important roles in regulating plant growth and development. Because hormone responses are usually concentration-dependent, endogenous hormone levels must be tightly controlled. Glycosylation may be one of the important modifications modulating active hormone levels. With the cloning and identification of glycosyltransferases genes involved in glycosylation of plant hormones, the mechanism and roles of glycosylation of different plant hormones were gradually revealed. This review focuses on recent research progress in understanding enzyme activities and biological functions of glycosyltransferases for auxins, cytokinins, abscisic acids, brassinosteroids, salicylic acid and jasmonic acid. We discuss remaining questions to be answered and prospects for hormone glycosylation study. |
