Gentian plants have vivid blue-colored flowers, caused by accumulation of a polyacylated anthocyanin 'gentiodelphin'. We previously performed expression analysis of gentiodelphin biosynthetic genes, and hypothesized that the white-flowered gentian cultivar 'Polarno White' might have resulted from the mutation of certain regulatory factors responsible for anthocyanin biosynthesis in flower petals. In this study, we isolated 26 R2R3-MYB gene fragments including four full-length cDNAs (GtMYB2a… CONTINUE READING
