UGT — Medicago truncatula

Summary

MTR_8G083300, designated MtUGT, encodes a UDP-glycosyltransferase with multiple glucosyltransferase activities, including anthocyanin 5-O-glucosyltransferase, flavanone 7-O-beta-glucosyltransferase, and indole-3-acetate beta-glucosyltransferase. This barrel medic gene on chromosome 8 is associated with secondary metabolism, isoflavonoid and saponin anabolism, anthocyanin biosynthesis and accumulation, pigmentation, and detoxification. It has been linked to regulation of abscisic acid signalling, negative regulation of response to water deprivation, seed growth and development, fruit ripening, pollen tube growth, root hair development, and fungal symbiosis. The gene product localizes to the cytoplasm, nucleus, Golgi complex, and plasmalemma. Studies of related genes in other species connect this gene family to ABA accumulation, sinapate metabolism, lignin synthesis, and p-aminobenzoate glucose ester formation.
