DFR — Brassica napus

Summary

BnDFR (DARMORV10_C02P43210.1) on chromosome C02 of oilseed rape encodes a protein with NmrA-like and NAD(P)-binding domains that exhibits dihydroflavonol 4-reductase, flavanone 4-reductase, chalcone isomerase, naringenin-chalcone synthase, flavonol synthase, and oxidoreductase activities. The gene is associated with anthocyanin breakdown and regulation, pigment metabolism, flavonol biosynthesis, proanthocyanidin anabolism, cell cycle transition, leaf formation, integument development, and response to gravity. It has been linked to seed color, flavonoid content, leaf color, anthocyanin content, chlorophyll content, seed size, photosynthetic ability, stamen morphology, root phototropism, UV-B sensitivity, herbicide sensitivity, lignin content, insect damage response, low temperature and oxidative stress tolerance, and root-knot nematode resistance. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
