AAT1 — Cucumis melo

Summary

MELO3C035503.2 (symbol AAT1, also known as CmAAT1) encodes a basic amino acid permease with L-lysine, L-glutamate and basic amino acid transmembrane transporter activity, belonging to the CAT_C and AA/rel_permease1 domain families. In melon, this gene is associated with L-arginine import, basic amino acid transport, the lipoxygenase pathway, sucrose metabolism, and fruit ripening. It is linked to sugar content and photosynthetic rate, as well as to amino acid transport, plant biomass, flowering time, resistance to Pseudomonas syringae, and glutamine transport. The encoded protein localises to the membrane, plant-type vacuole, mitochondria, plasmalemma, cytoplasm, and intracellular membrane-bounded organelles. Studies of related genes in other species connect the family to fruit flavour and ripening traits, drought and salt tolerance, disease resistance, and volatile ester production.
