Figure 1. Schematic diagram representing the flavonoid pathway of anthocyanin and proanthocyanidin biosynthesis in plants. Enzymes are shown in boldface. CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3′-hydoroxylase; F3′5′H, flavonoid 3′,5′-hydoroxylase; DFR, dihydroflavonol 4-reductase; ANS, anthocyanidin synthase; 3GT, UDP-glucose: flavonoid 3-O-glycosyltransferase; LAR, leucoanthocyanidin reductase; ANR, anthocyanidin reductase.
