AAT1 — Capsicum annuum

Summary

CaAAT1 (T459_08721) on pepper chromosome 3 encodes a cationic amino acid transporter 8, vacuolar, with L-lysine, L-glutamate, basic amino acid and amino acid permease activities. It is associated with basic amino acid transport, L-arginine import, fruit development and ripening, response to wounding and aluminum, and localises to the plant-type vacuole, membrane, mitochondria, plasmalemma and cytoplasm. The gene is linked to cell membrane stability, shoot fresh weight, photosynthetic rate and chlorophyll content, as well as amino acid transport, plant biomass, flowering time, resistance to Pseudomonas syringae and glutamine transport. Studies of related genes in other species connect the family to fruit flavor and ripening traits, root volume, soluble protein and sugar content, drought and salt tolerance, disease tolerance, viral resistance, volatile ester production, and responses to high-light, oxidative, cadmium and aluminum stress.
