AAT1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G008070 (symbol AAT1) on durum wheat chromosome 5B encodes a basic amino acid permease with a CAT_C domain and an AA/rel_permease1 domain, possessing basic amino acid permease, L-lysine, and L-glutamate transmembrane transporter activities. The gene is associated with L-arginine import, basic amino acid transport, cellular amino acid homeostasis, hydrogen peroxide biosynthesis, and response to nematodes. It is linked to leaf senescence, stomatal closure, drought tolerance, cold tolerance, oxidative stress tolerance, seed dormancy, salt tolerance, stomatal development, seed germination, hydrogen peroxide accumulation, circadian rhythm, programmed cell death, light response, jasmonic acid biosynthesis, pathogen resistance, auxin accumulation, and seedling and root growth. The encoded protein localizes to the nuclear envelope, tonoplast, endoplasmic reticulum, mitochondria, and plasmalemma.
