BAN — Brassica napus

Summary

BnBAN (DARMORV10_A03P67180.1) on chromosome A03 of oilseed rape (Brassica napus) encodes an NAD(P)-binding epimerase/dehydratase family protein with oxidoreductase activity acting on CH-OH groups, and is annotated with anthocyanidin reductase, racemase and epimerase, flavanone 4-reductase, and dihydroflavanol 4-reductase activities. The gene is associated with proanthocyanidin and condensed tannin biosynthesis, seed coat development and pigmentation, seed color, and mucilage anabolism. It is also linked to negative regulation of flavonoid anabolism, anthocyanin and phenylpropanoid metabolism, lignin and fatty acid biosynthesis, embryogenesis, cell differentiation, trichome branching, and photosynthetic rate. Related genes in other species link the family to proanthocyanidin accumulation, anthocyanidin reduction, and seed coat pigmentation.
