3MAT — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0196910 (symbol 3MAT, also known as HvAACT1) on barley chromosome 2H encodes a member of the plant metabolite acyltransferase family with a CAT-like domain superfamily. The encoded protein possesses multiple malonyltransferase and acyltransferase activities, including flavonol-3-O-glucoside O-malonyltransferase and anthocyanin 6''-O-malonyltransferase activity. In barley, this gene is directly associated with aluminium tolerance, aluminum tolerance, and acid soil resistance, and is linked to citrate secretion, citrate transport, detoxification, defense response, and phenylpropanoid and anthocyanin metabolism. The gene product localises to the cytoplasm. Studies of related genes in other species link the family to aluminium resistance.
