摘　　要：花青素是高等植物体内非常重要的一类次生代谢产物,能够决定花和果实的颜色,同时具有很高的营养、保健功能。MYB蛋白是植物花青素合成途径中最广泛的调节因子,在植物花青素合成方面起着重要的调控作用。本研究阐述了花青素合成的研究现状,介绍了MYB基因在不同植物花青素合成中的正负调控作用,总结了MYB基因如何与其他因子相互作用调控花青素的合成以及外界环境因素对花青素合成的影响,旨在为作物品种改良提供理论依据,以期培育出富含花青素、安全优质的农作物品种。Anthocyanins are a very important type of secondary metabolites in higher plants,which can determine the color of flowers and fruits,and at the same time have high nutrition and health functions.MYB protein is the most extensive regulatory factor in the synthesis of plant anthocyanins,and plays an important regulatory role in the synthesis of plant anthocyanins.This paper describes the current research status of anthocyanin synthesis,intro-duces the positive and negative regulatory effects of MYB gene in anthocyanin synthesis of different plants,and summarizes how MYB gene interacts with other factors to regulate anthocyanin synthesis and the influence of ex-ternal environmental factors on the synthesis of anthocyanins.This review aims to provide a theoretical basis for the improvement of crop varieties,with a view to cultivating crop varieties that are rich in anthocyanins,safe and high-quality.
