AAT — Phaseolus vulgaris

Summary

PHAVU_001G250600 (PvAAT) encodes a pyridoxal phosphate-dependent aminotransferase belonging to the AspAT/PAT-like family, with LL-diaminopimelate, nicotianamine, and multiple aromatic and aliphatic aminotransferase activities. In French bean, this gene is associated with ureide anabolism, tyrosine breakdown, L-phenylalanine anabolism, ethylene biosynthesis, systemic acquired resistance via salicylic acid signaling, and embryo development. The product localizes to the amyloplast membrane and chloroplast stroma. This gene is associated with aromatic amino acid biosynthesis. Sequence similarity connections further associate related genes in other species with seed protein content, amino acid content, drought tolerance, root morphology, and glufosinate sensitivity, though these relationships are not established for PvAAT itself.
