AAT1 — Cucumis melo

Summary

MELO3C002398.2 (symbol AAT1, 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 basic amino acid transport, L-arginine import, the lipoxygenase pathway, sucrose metabolism, and fruit ripening. It is linked to sugar content, photosynthetic rate, plant biomass, flowering time, and resistance to Pseudomonas syringae. The encoded protein localizes to the membrane, plant-type vacuole, cytoplasm, mitochondria, and intracellular membrane-bounded organelles. Studies of related genes in other species connect the family to fruit flavor and ripening traits, volatile ester production, drought and salt tolerance, oxidative stress response, and disease tolerance.
