AAT1 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G230830 (symbol AAT1, also known as CAT2, CAT3, CAT4, CAT5) on durum wheat chromosome 2A encodes a cationic amino acid transporter with basic amino acid permease activity, L-lysine and L-glutamate transmembrane transporter activity, and amino acid permease activity. The gene is associated with L-arginine import, basic amino acid transport, cellular amino acid homeostasis, H2O2 biosynthetic process, and response to nematodes. It localizes to the nuclear envelope, tonoplast, plant-type vacuole, ER, mitochondria, membrane, plasmalemma, and cytoplasm. AAT1 is associated with leaf senescence, stomatal closure, drought tolerance, cold tolerance, oxidative stress tolerance, seed dormancy, salt tolerance, stomatal development, seed germination, hydrogen peroxide accumulation, circadian rhythm, light response, jasmonic acid biosynthesis, pathogen resistance, auxin accumulation, and amino acid concentration.
