AAT — Cicer arietinum
Summary
CaAAT (LOC101498423) on chickpea chromosome 6 encodes a pyridoxal phosphate-dependent aminotransferase belonging to the AspAT/PAT-like family, with multiple transaminase activities including LL-diaminopimelate, nicotianamine, and L-tyrosine-2-oxoglutarate aminotransferase activities, as well as 1-aminocyclopropane-1-carboxylate synthase activity. The gene is associated with tyrosine breakdown, L-phenylalanine biosynthesis, ethylene biosynthesis, systemic acquired resistance via salicylic acid signaling, embryo development, and response to thirst. It is linked to leaf relative water content, seed protein content, root length, and drought tolerance. The product localizes to the amyloplast membrane and chloroplast stroma. Related genes in other species are linked to nitrogen metabolism and amino acid content.
