DFR — Medicago truncatula

Summary

MTR_1G022445, designated MtDFR, encodes a protein with flavanone 4-reductase, dihydroflavanol 4-reductase, chalcone isomerase, naringenin-chalcone synthase, and flavonol synthase activities. The gene is associated with anthocyanin, proanthocyanidin, flavonol, and isoflavonoid biosynthesis, as well as responses to UV-B, jasmonic acid, wounding, oxidative stress, and mercury. It is linked to seed development, auxin polar transport, and cell development. Associations with traits include anthocyanin content, seed coat pigmentation, root-knot nematode resistance, abiotic stress tolerance, photosynthetic ability, leaf size, petiole length, and low temperature stress response. The protein localises to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species link the family to flavonoid production, seed colour, drought and salt tolerance, and male fertility.
