植物花青素生物代谢调控

Metabolic Regulation of Plants Anthocyanin

花青素是一类重要的天然色素物质,是植物的主要呈色物质之一,近年来花青素在保健方面的作用越来越受到人们的重视,利用基因工程改造植物花青素相关基因,提高花青素含量已成为研究的热点领域。综述花青素的合成途径、调控机理及转基因方面的研究,重点介绍近年来影响花青素合成的分子因素及外部环境因素的研究现状。

Anthocyanin is a group of important natural pigments,and it＇s also one of the most important plant pigments.Recent years,as a free-radical scavenger,more research focus on the role of anthocyanins in healthy,so an important research object is to increase anthocyanin content by genetic engineering.This review summarizes the anthocyanin biosynthesis pathway,regulation mechanism and genetic engineering in plants.The environmental factors on the biosynthesis of anthocyanin also been emphasized in this article.
