拟南芥种皮色素形成机制研究进展

摘要/Abstract

摘要： 类黄酮为拟南芥种皮的主要成色物质,其生物合成过程受到一系列基因的影响.这些基因中,一部分为结构基因(TT4、TT5、TT6、TT7、FLS1TT3，LDOX 和BAN)编码一些酶类参与到类黄酮的生物合成;一部分作为调控基因(TT1, TT2, TT8, TTG1, TTG2 和TT16)编码一些酶对生物合成途径起调控作用;另外一些基因（TT12, TT19）编码与色素转运、积累相关的蛋白质。这些基因中的一种或几种发生变异就能影响到类黄酮的生物合成，从而引起拟南芥种皮色泽的变异。在此，就拟南芥种皮的色泽变异及类黄酮生物合成机理作一介绍。

Abstract: Flavonoids are responsible for the testa color of Arabidopsis thaliana. The biosynthesis process of flavonoids is influenced by many types of genes. Some of the genes act as structure genes (such as TT4,,TT5, TT6, TT7, FLS1, TT3, LDOX and BAN); Some of them encode enzyme as regulating genes (TT1, TT2, TT8, TTG1, TTG2 and TT16);others encode transfering proteins (TT12, TT19). Mutation of one or more of them can influence the biosynthesis of flavonoids causing the varation of the testa of Arabidopsis thaliana. This review deals with the variation of testa luster as well as the mechanism of flavonoid biosynthesis in Arabidopsis thaliana .
