The biosynthetic relationship between anthocyanins, flavonols, and proanthocyanidins. Enzymes catalysing the respective steps are indicated by arrows, and putative steps are shown as dotted arrows. Abbreviations: 3GT, flavonoid 3-glucosyltransferase; ANR, anthocyanidin reductase; ANS, anthocyanidin synthase; CHS, chalcone synthase; CHI, chalcone isomerase; DFR, dihydroflavonol 4-reductase; F3H, flavanone 3-hydroxylase; F3′H, flavonoid 3′-hydroxylase; F3′5′H, flavonoid 3′5′-hydroxylase; FLS, flavonol synthase; LAR, leucoanthocyanidin reductase; RT, rhamnosyltransferase; UFGT, glucose-flavonoid glucosyl transferase
