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 .
