DFR — Glycine max

Summary

GmDFR (GLYMA_17G252200V4) encodes a protein with flavanone 4-reductase, dihydroflavanol 4-reductase, chalcone isomerase, naringenin-chalcone synthase, and flavonol synthase activities, belonging to the NAD(P)-dependent dehydratase/epimerase family. This soybean gene on chromosome 17 is associated with flavonoid and secondary metabolite biosynthesis, pigmentation, vacuolar acidification, and hormone metabolism. It has been linked to flower and seed color, anthocyanin content and accumulation, proanthocyanidin seed coat pigmentation, and flavonol content. Associations also include leaf weight, specific leaf weight, photosynthetic ability, carbohydrate and protein content, heterosis, root gravitropic and phototropism responses, stamen development, and responses to UV light, oxidative stress, low temperature, nitrogen stress, and pathogens including root-knot and cyst nematodes. Studies of related genes in other species link the family to flavonoid production, seed coat pigmentation, drought and salt tolerance, and UV-B sensitivity.
