Schematic representation of flavonoid biosynthesis and gene expression profiles. (A) Summary of the anthocyanin/flavonoid biosynthetic pathway. Dihydroflavonol 4-hydroxylase (DFR), anthocyanidin synthase (ANS) and UDP-glucose: anthocyanin 3-glucosyltransferase (3GT) are anthocyanin biosynthesis enzymes. Glutathione S-transferase (GST) plays a role in anthocyanin transportation into vacuoles. (B) The expression profiles of DFR (Dca4324), ANS (Dca23371), 3GT1 (Dca47835), 3GT2 (Dca17573), GST (Dca57804) and bHLH (Dca31716) in red petals of ‘4-94-1 MR’ (black bar) and in white petals of ‘2-241-1 MB’ (white bar) at petal stages 1 to 4.
