AAT1 — Nicotiana attenuata

Summary

A4A49_34565 (AAT1/CAT1) in coyote tobacco (Nicotiana attenuata) encodes a basic amino acid permease with L-lysine, L-glutamate, and basic amino acid transmembrane transporter activity, belonging to the AA/rel_permease1 family. It is associated with L-arginine import, basic amino acid transport, cellular homeostasis, detoxification, ethylene anabolism, auxin signaling, and response to aluminum. The gene is linked to fruit development, signal transduction, and localization to the plant-type vacuole, mitochondria, plasmalemma, and cytoplasm. Associations with photosynthetic traits include quantum yield, net photosynthetic rate, transpiration rate, stomatal resistance, and photochemical quenching. It is also connected to plant biomass, flowering time, and resistance to Pseudomonas syringae. Related genes in other species are linked to salt, drought, and oxidative stress tolerance, viral resistance, fruit ripening, and volatile ester production.
