From: Molecular evolution of anthocyanin pigmentation genes following losses of flower color
Core anthocyanin biosynthetic pathway adapted from Rausher [56]. Enzymes include: CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone-3-hydroxylase; DFR, dihydroflavonol reductase; ANS, anthocyanidin synthase; and UF3GT, UDP-glucose flavonoid 3-O-glucosyl transferase. Several of the steps required for anthocyanin pigment production are shared with other uncolored flavonoid compounds (e.g., flavones and flavonols). The enzymes examined in this study are shaded in gray
