Null mutants for structural genes are in general devoid of anthocyanin pigment in all plant parts whereas regulatory mutants show altered colour patterns relative to wild-type. We show that this variegation is attributable to an unstable mutant allele of the gene encoding dihydroflavonol-4-reductase, one of the enzymes required for anthocyanin biosynthesis. Antioxidant levels of purified anthocyanin extracts were much higher than expected from anthocyanin content indicating synergistic effect of anthocyanin mixtures.
