AAT1 — Cucumis melo

Summary

MELO3C016149.2, also known as CmAAT1, encodes a basic amino acid permease with L-lysine and L-glutamate transmembrane transporter activity, belonging to the CAT_C and AA/rel_permease1 domain families. In melon, this gene is associated with L-arginine import, the lipoxygenase pathway, basic amino acid transport, sucrose metabolism, and fruit ripening. It is linked to sugar content, photosynthetic rate, plant biomass, flowering time, resistance to Pseudomonas syringae, and amino acid and glutamine transport. The encoded protein localizes to the membrane, plant-type vacuole, mitochondria, plasmalemma, cytoplasm, and intracellular membrane-bounded organelles. Related genes in other species are associated with fruit flavor and ripening traits, drought and salt tolerance, oxidative stress response, viral and pathogen resistance, volatile ester production, and various growth and photosynthetic parameters.
