AAT1 — Triticum aestivum

Summary

TRAESCS1D02G137900, designated TaAAT1 on bread wheat chromosome 1D, encodes a basic amino acid permease with transmembrane transporter activity, specifically transporting L-lysine, L-glutamate, and L-arginine. The protein belongs to the AA/rel_permease1 family and contains a CAT_C domain. TaAAT1 is associated with cellular amino acid homeostasis, amino acid membrane transport, and basic amino acid import. It is linked to calcium signaling, response to arsenic, response to nematodes, regeneration, somatic embryogenesis, and embryogenesis. The gene is associated with traits including hydrogen peroxide content, callus induction, and salt tolerance. It is linked to leaf senescence, stomatal closure, drought tolerance, cold tolerance, seed dormancy, seed germination, oxidative stress tolerance, and pathogen resistance. The protein localizes to the tonoplast, nuclear envelope, endoplasmic reticulum, mitochondria, and plasmalemma. Studies of related genes in other species link the family to vacuolar amino acid transport, salt stress tolerance, and seed germination under low-temperature stress.
