糖基转移酶（GT）是能够催化糖基从激活的供体转移到特定的受体分子上的一类酶，在生物体中普遍存在，形成超基因家族。糖基转移酶广泛参与植物生命活动的各种生物学过程，尤其在植物次生代谢途径中发挥重要作用。本文概述了糖基转移酶在植物次生代谢途径中的研究进展，描述了该基因家族及其与植物次生代谢途径进化的关系，并总结了目前糖基转移酶类基因克隆的方法和新策略。

Glycosyltransferases (GT) are able to catalyze the glycosyl transfer to a specific receptor molecule on a class of enzymes from the activated donor. The organisms are widespread in a large number of glycosyltransferase enzymes, and the formation of the super-gene family. GT have been widespread concerning for the importance of plant life and its potential economic value. This article provided an overview of the role of GT in the plant secondary metabolites, describing the gene family and its evolutionary relationship with plant secondary metabolic pathways, and summarizes the cloning methods and new strategies.
