UGT — Medicago truncatula

Summary

MTR_8G083290 (UGT, MtUGT) encodes a UDP-glycosyltransferase family protein on barrel medic chromosome 8. The enzyme exhibits multiple glucosyltransferase activities, including anthocyanin 5-O-glucosyltransferase, flavanone 7-O-beta-glucosyltransferase, quercetin 3-O- and 7-O-glucosyltransferase, and UDP-glucose:4-aminobenzoate acylglucosyltransferase activity. MtUGT is associated with anthocyanin and isoflavonoid biosynthesis, secondary metabolism, saponin anabolism, pigmentation, detoxification, and regulation of abscisic acid-mediated signaling. It is linked to negative regulation of response to water deprivation, fruit ripening, pollen tube growth, and response to salicylate. The gene is associated with seed growth and development traits, drought tolerance, osmotic and salt stress tolerance, root gravitropism, root hair development, and fungal symbiosis. Related genes in other species link the family to ABA accumulation and p-aminobenzoate glucose ester formation.
