【摘要】 花色素是由植物类黄酮代谢途径产生的次生代谢产物,决定了花、果实和种子的颜色。随着类黄酮代谢途径的研究不断地深入,多种植物编码合成花青素的酶基因也已得到克隆,并研究证明花色素合成基因与转录因子(MYB、bHLH和WD40)有着极其复杂的相互作用模式。本文主要对花青素合成相关的MYB、bHLH和WD40转录因子及其在调节结构基因表达和花青素合成中的作用进行了综述。更多还原

【Abstract】 Anthocyanins are secondary metabolites that produced by a specific branch of the flavonoid pathway.They can determine the colors of flowers,fruits and seeds.As flavonoids biosynthesis pathway research unceasingly thorough,of various plants have been cloned,and the previous studies have shown that anthocyanins enzyme genes were activated by transcription factors(MYB,bHLH and WD40) with complex interaction patterns.In this paper,MYB transcription factors,bHLH transcription factors and WD40 repeat protein involved in anthocyanin biosynthesis and their roles in the regulation of structural gene expression and anthocyanin synthesis are reviewed.更多还原
