BAN — Brassica oleracea

Summary

BoBAN (BOLC102_C01P042560.1) on cabbage chromosome 1 encodes a protein with NAD(P)-binding and epimerase/dehydratase domains and exhibits anthocyanidin reductase, flavanone 4-reductase, and dihydroflavanol 4-reductase activities, along with racemase/epimerase and NADP-binding functions. The gene is associated with chlorophyll metabolism and breakdown, negative regulation of flavonoid anabolism, pigmentation, and carbohydrate metabolism. It is linked to leaf color, anthocyanin content, chlorophyll a and b content, net photosynthetic rate, transpiration rate, stomatal resistance, and photosynthetic rate. Associations also include proanthocyanidin and condensed tannin biosynthesis. Studies of related genes in other species link the family to proanthocyanidin accumulation, anthocyanin accumulation, seed coat development, and seed germination.
