摘要：糖基转移酶属于催化糖基转移反应的超基因家族的一类酶。糖基化修饰能丰富花青素的结构,调节其水溶性、稳定性和可转运性,决定植物色泽形成。对参与观赏植物花色素成分合成代谢的糖基转移酶的种类及其生化、分子生物学研究进行梳理,并对其在蓝紫色、橙色-紫红色以及黄色等主要花瓣色泽形成中的作用进行归纳,展望色泽相关糖基转移酶的研究方向,以期为深入解析花色素物质的糖基化修饰机理提供参考,也为观赏植物花色改良提供新思路。
Glycosyltransferases belong to a super gene family that catalyze glycosylation.Glycosylation modifications could enrich the structure of anthocyanidins,regulate its water solubility,stability and transportability,which are considered as important steps for petal color determinant.In this research,we reviewed the categories,biochemical and molecular biology of glycosyltransferases involved in the pigment metabolism in ornamental plants.In addition,the effects of some glycosyltransferases in the pigmentation of differently colored petals,such as blue-violet,orange to purplish red and yellow,are summarized.Finally,further research hotspots of pigmentation related glycosyltransferases are prospected.The results are expected to provide a reference for further understanding of the mechanism of glycosylations,and shed lights to the improvement of ornamental plant flower color through molecular breeding strategy.
