DFR — Brassica napus

Summary

BnDFR (DARMORV10_A09P19990.1) on chromosome A09 of oilseed rape encodes a protein with NAD(P)-binding and epimerase/dehydratase domains that exhibits dihydroflavonol 4-reductase, flavanone 4-reductase, chalcone isomerase, naringenin-chalcone synthase, and flavonol synthase activities, along with protein binding. This gene is associated with anthocyanin breakdown and regulation, pigment metabolism and accumulation, flavonol and proanthocyanidin biosynthesis, chalcone and hormone anabolism, and responses to gravity, UV light, and oxidative stress. It is linked to seed color, flavonoid and anthocyanin content, leaf color, photosynthetic ability, seed size, chlorophyll content, lignin content, herbicide sensitivity, low temperature and nitrogen stress tolerance, root-knot nematode resistance, and stamen and flower development traits. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
