To elucidate gene regulation of flower colour formation, the gene expressions of the enzymes involved in flavonoid biosynthesis were investigated in correlation with their product during floral development in lisianthus. Full-length cDNA clones of major responsible genes in the central flavonoid biosynthetic pathway, including chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid 3',5'-hydroxylase (F3'5'H), dihydroflavonol 4-reductase (DFR), anthocyanidin synthase (ANS), and flavonol synthase (FLS), were isolated and characterized. In lisianthus, the stage of the accumulation of flavonols and anthocyanins was shown to be divided clearly. The flavonol content increased prior to anthocyanin accumulation during floral development and declined when anthocyanin began to accumulate. CHS, CHI, and F3H were necessary for both flavonol and anthocyanin biosynthesis and were coordinately expressed throughout all stages of floral development; their expressions were activated independently at the stages corresponding to flavonol accumulation and anthocyanin accumulation, respectively. Consistent with flavonol and anthocyanin accumulation patterns, FLS, a key enzyme in flavonol biosynthesis, was expressed prior to the expression of the genes involved in anthocyanin biosynthesis. The genes encoding F3'5'H, DFR, and ANS were expressed at later stages, just before pigmentation. The genes responsible for the flavonoid pathways branching to anthocyanins and flavonols were strictly regulated and were coordinated temporally to correspond to the biosynthetic order of their respective enzymes in the pathways, as well as in specific organs. In lisianthus, FLS and DFR, at the position of branching to flavonols and anthocyanins, were supposed to play a critical role in regulation of each biosynthesis. 相似文献
