Schematic representation of the flavonoid biosynthetic pathway in apple regulated by MYB10. Flavonoid intermediates (gray boxes) and end products (black boxes) are indicated. Enzymes required for each step are shown in bold uppercase letters (PAL, phenylalanine ammonia lyase; CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone-3β-hydroxylase; FLS, flavonol synthase; GT, unidentified enzyme encoding a glycosyl transferase for flavonol glycone synthesis; DFR, dihydroflavonol-4-reductase (denoted as DFR1 in the text); LAR, leucoanthocyanidin reductase; LDOX, leucoanthocyanidin dioxygenase; ANR, anthocyanidin reductase; UFGT, UDP-glycose:flavonoid-3-O-glycosyltransferase (adapted from [17]).
