DFR — Brassica napus

Summary

BnDFR (DARMORV10_C09P25350.1) on chromosome C09 of oilseed rape (Brassica napus) 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. The gene is associated with anthocyanin breakdown, pigment metabolism, flavonol biosynthesis, proanthocyanidin anabolism, and regulation of phenylpropanoid metabolism. It has been linked to seed color, flavonoid content, leaf color, anthocyanin content, chlorophyll content, photosynthetic ability, seed size, lignin content, and responses to UV light, oxidative stress, low temperature, and nitrogen stress. Additional associations include root phototropism, stamen morphology, flower development, pollen fertility, stomatal closure, and resistance to root-knot nematodes and cyst nematodes. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
