Abstract

Anthocyanins, other flavonoids, and phenolic acids belong to a group of plant natural products with antioxidant activity and may play important roles in plant protection against biotic and abiotic stress and in protection against human diseases. In the present study, the Arabidopsis regulatory gene Production of Anthocyanin Pigment 1 (AtPAP1) was expressed in Brassica napus (canola), and its presence enhanced the antioxidant capacity in transgenic leaves up to 4-fold. Transgenic plants had intense purple coloration, cyanidin and pelargonidin levels were enhanced 50-fold, and quercetin and sinapic acid were 5-fold higher. Consistent with these phytochemical and biological changes, expression for most genes in the flavonoid and phenolic acid biosynthetic pathways was also stimulated.
