Genome-wide identification of antioxidant component biosynthetic enzymes: Comprehensive analysis of ascorbic acid and tocochromanols biosynthetic genes in rice

► Identification of eight and seven potential non-redundant members involved in ascorbic acid and tocochromanol biosynthetic pathways. ► The promoter regions of the rice AsA and tocochromanol biosynthesis genes contained the light-responsive, hormone-responsive, and stress-responsive elements. ► Ascorbic acid and tocochromanols are regulated with abiotic and biotic stress responses.
