Abstract excerpt

KEY MESSAGE: Loss of DFR function in petunia alters pigment metabolism and reduces organ size, suggesting previously underexplored associations among flavonoid biosynthesis, plastidial pigments, and development. Dihydroflavonol 4-reductase (DFR) occupies a critical branch point in flavonoid metabolism, channeling dihydroflavonol substrates toward anthocyanin biosynthesis in competition with flavonol synthase....
