BAN — Brassica napus

Summary

BnBAN (DARMORV10_C01P38970.1) on oilseed rape chromosome C01 encodes a protein with NAD(P)-binding and epimerase/dehydratase domains that exhibits anthocyanidin reductase, flavanone 4-reductase, and dihydroflavanol 4-reductase activities, along with racemase and epimerase activity. The gene is associated with seed coat development, pigmentation, proanthocyanidin and condensed tannin biosynthesis, and negative regulation of flavonoid anabolism. It has been linked to seed color and seed coat color traits, as well as photosynthetic rate. Related genes in other species are associated with proanthocyanidin accumulation, anthocyanidin reduction, and condensed tannin accumulation. The gene is also associated with mucilage and lignin anabolism, embryogenesis, cell differentiation, and trichome branching.
