摘　　要：花青素对植物生长发育和人体健康十分重要,紫色蔬菜富含花青素,越来越受到消费者的青睐。近年来,芸薹属作物花青素合成调控研究取得了一定的进展,部分紫色变异相关基因已被确定,其中MYB和bHLH等家族转录因子在芸薹属作物花青素生物合成调控中起着关键作用,它们能够与花青素合成结构基因启动子区元件结合,上调或下调结构基因的表达,进而激活或抑制花青素的生物合成。本文在介绍花青素结构与分类、生物合成途径的基础上,从MYB转录因子、bHLH转录因子、BBX转录因子及WRKY转录因子等方面综述了近年来芸薹属作物花青素合成与调控相关基因的研究进展;指出芸薹属作物花青素分子调控受多基因和环境因素的影响,未来可通过转基因技术和基因编辑技术对紫色基因进行定向改良,为今后开展芸薹属作物花青素分子调控解析及紫色新品种选育提供参考和理论依据。Anthocyanins are crucial for plant growth and development as well as human health.Purple vegetables are rich in anthocyanins which making them increasingly favored by consumers.In recent years,some progresses have been made in the regulation of anthocyanin synthesis in Brassica crops,and some mutant genes of purple have been identified.Among them,transcription factors family such as MYB and bHLH play key roles in the regulation of anthocyanin biosynthesis in Brassica crops,which can bind to elements in the promoter regions of anthocyanin synthesis structural genes,upregulating or downregulating the expression of these structural genes,thereby activating or inhibiting anthocyanin biosynthesis.On the basis of introducing the structure,classification and biosynthetic pathways of anthocyanins,this article reviews the research progress on anthocyanin synthesis and regulation related genes in Brassica crops in recent years from the aspects of MYB transcription factor,bHLH transcription factor,BBX transcription factor and WRKY transcription factor.It is pointed out that the molecular regulation of anthocyanins in Brassica crops is affected by multiple genes and environmental factors,and the purple gene can be improved directionally by transgenic technology and gene editing technology.It provides a reference and theoretical basis for the analysis of molecular regulation of anthocyanins in Brassica crops and the breeding of new purple varieties in the future.
