5MAT1 — triticum aestivum

Summary

TRAESCS6B02G437900 (symbol 5MAT1, also known as TaAACT1) on bread wheat chromosome 6B encodes a plant metabolite acyltransferase with malonyltransferase activity, specifically acting on flavonol-3-O-beta-glucoside, anthocyanin 6''-O-malonyltransferase, anthocyanin 5-aromatic acyltransferase, and hydroxycinnamoyltransferase substrates. The gene is associated with the mevalonate (MVA) pathway, phenylpropanoid and alkaloid metabolism, anthocyanin accumulation in response to UV light, and xenobiotic metabolism. It is linked to resistance to Fusarium crown rot in wheat. Associations with agronomic traits include grain size, grain weight, grain yield, plant height, heading time, anthesis time, root volume and number, drought tolerance, heterosis, and cytoplasmic male sterility. The encoded protein localizes to the cytoplasm and is linked to meristem initiation, maintenance, and regulation, as well as flower morphogenesis and determination of bilateral symmetry.
