DFR — Brassica juncea

Summary

BJUA09G53520S (BjDFR) encodes a protein with chalcone isomerase, naringenin-chalcone synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, and flavonol synthase activities, and belongs to the NAD(P)-binding domain superfamily. In Indian mustard, this gene is associated with anthocyanin, flavonoid, and phenylpropanoid biosynthesis, pigmentation, leaf formation, response to UV-B and gravity, auxin polar transport, and cell cycle transition. It is linked to seed color, flavonoid and anthocyanin content, leaf color, seed size, photosynthetic ability, stamen morphology, root phototropism, herbicide sensitivity, and responses to UV light, oxidative stress, and low temperature. Associations also include root-knot nematode resistance, proanthocyanidin biosynthesis, and abiotic stress tolerance. Related genes in other species are linked to UV-B sensitivity, flavonoid production, seed coat pigmentation, and drought tolerance.
