DFR — Brassica juncea

Summary

BJUA03G09610S (symbol DFR) on Indian mustard chromosome A03 encodes a protein with NAD(P)-binding and epimerase/dehydratase domains, and exhibits flavanone 4-reductase, dihydroflavanol 4-reductase, and cinnamyl-alcohol dehydrogenase activities, acting as an oxidoreductase acting on CH-OH groups with NAD or NADP as acceptor. This gene is associated with pigmentation, regulation of anthocyanin anabolism, phenylpropanoid anabolism, NO storage, anthocyanin anabolism, and flavonoid anabolism, and is linked to seed color and anthocyanin content. The encoded protein localizes to the nucleus. Studies of related genes in other species connect the family to leaf shape and photochemical quenching, though these associations are not established for this gene.
