AAT1 — Brassica oleracea var. botrytis

Summary

BoAAT1 (BOLND125_C03P081070.1_BOLND125_V1) on cauliflower chromosome 3 encodes a protein with a CAT_C domain and an AA/rel_permease1 domain, possessing L-lysine, L-glutamate, and basic amino acid transmembrane transporter activities. It is associated with basic amino acid transport, L-arginine import, and chlorophyll fluorescence, and localises to the membrane, plasmalemma, and cytoplasm. The gene is linked to resistance to Pseudomonas syringae, flowering time, and plant biomass. Studies of related genes in other species connect the family to salt tolerance, oxidative stress tolerance, high-light stress tolerance, cadmium tolerance, and pathogen resistance, and to amino acid transport. Sequence similarity further associates the family with leaf color, flowering time, drought tolerance, and disease tolerance.
