ANR — Brassica juncea

Summary

BJUA01G14131S (symbol ANR, also known as BjBAN) on Indian mustard (Brassica juncea) chromosome A01 encodes a protein with NAD(P)-binding and epimerase/dehydratase domains, exhibiting anthocyanidin reductase, racemase and epimerase, flavanone 4-reductase, dihydroflavanol 4-reductase, and oxidoreductase activities, and NADP binding. The gene is associated with pigmentation, seed development, cell cycle transition, and the biosynthesis of anthocyanins, flavonoids, phenylpropanoids, proanthocyanidins and condensed tannins. It is linked to negative regulation of flavonoid anabolism, lipogenesis, triglyceride anabolism, NO storage and seed colour, seed size and photosynthetic rate traits. Studies of related genes in other species connect the family to proanthocyanidin and condensed tannin accumulation, anthocyanidin reduction, seed coat development and pigmentation, and seed germination.
