AAT1 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G053550 (symbol AAT1) on durum wheat chromosome 3A encodes an amino acid permease with basic amino acid permease activity, L-lysine and L-glutamate transmembrane transporter activity. The protein localises to the nuclear envelope, tonoplast, endoplasmic reticulum, mitochondria, plasmalemma and cytoplasm. This 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, hydrogen peroxide scavenging, reactive oxygen species homeostasis, jasmonic acid biosynthesis, pathogen resistance, auxin accumulation, and seedling and root growth. Studies of related genes in other species connect the family to vacuolar amino acid transport, photorespiratory stress tolerance, hypersensitive cell death, and abiotic stress responses.
