The expression of genes associated with flavonoid biosynthesis and its regulation in petal, pollen, dormant and sprouting buds of tea plants were analyzed by differential gene expression. The results showed that flavonoid biosynthetic genes were highly expressed in petal, dormant and sprouting buds, but rarely expressed in pollen, which is consistent with the distribution of flavonoids in tea plant. Furthermore, twelve genes in MYB, bHLH, MADS, GST, WD40 and Homeodomain gene families were identified to be correlated with flavonoid biosynthesis in petal. Nine genes were found to be involved in the regulation of flavonoid biosynthesis in tea buds. These results will be a basis for further understanding the mechanism of flavonoid biosynthetsis and regulation in Camellia sinensis.
