DFR — Brassica oleracea var. botrytis

Summary

BoDFR (BOLND125_C02P054430.1_BOLND125_V1) on cauliflower chromosome 2 encodes a protein with NmrA-like and NAD(P)-binding domains that exhibits flavanone 4-reductase, dihydroflavanol 4-reductase, chalcone isomerase, naringenin-chalcone synthase, flavonol synthase, and oxidoreductase activities. The gene is associated with anthocyanin, flavonoid, and phenylpropanoid biosynthesis and regulation, as well as pigmentation, responses to UV-B, oxidative stress, jasmonic acid, wounding, light, gravity, and auxin. It is linked to flavonoid and anthocyanin content, UV light sensitivity, photosynthetic ability, stamen and flower development, root phototropism, herbicide sensitivity, insect damage response, pollen fertility, stomatal closure, and low temperature, oxidative, and nitrogen stress tolerance. The protein localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Related genes in other species are associated with flavonoid production, seed coat pigmentation, UV-B sensitivity, drought and salt tolerance, and male fertility.
