ANR — Medicago truncatula

Summary

MTR_4G092080, designated ANR (MtBAN), encodes a protein with NAD(P)_dehydrat-like and epimerase_deHydtase domains on chromosome 4 of barrel medic (Medicago truncatula). The product possesses anthocyanidin reductase, dihydroflavanol 4-reductase, flavanone 4-reductase, racemase and epimerase activities, and binds NADP. It is associated with proanthocyanidin and anthocyanin biosynthesis, flavonoid metabolism, and negative regulation of flavonoid anabolism. The gene is linked to condensed tannin biosynthesis and localises to the chloroplast. Related genes in other species are linked to proanthocyanidin accumulation, seed coat development and pigmentation, anthocyanin content, seed germination, and flavonoid biosynthesis, as well as to seed coat colour, seed morphology, root morphology, and flavonoid content traits.
