AAT — Daucus carota subsp. sativus
Summary
DCAR_032171 (DcAAT) on carrot chromosome 1 encodes a pyridoxal phosphate-dependent aminotransferase with prephenate transaminase, nicotianamine aminotransferase, and 1-aminocyclopropane-1-carboxylate synthase activities. The gene is associated with tyrosine breakdown, L-phenylalanine biosynthesis, ethylene biosynthesis, and amino acid metabolism. It has been linked to systemic acquired resistance via salicylic acid signaling, somatic embryogenesis, regeneration, fruit ripening, and embryo development. Localization evidence connects the product to the amyloplast membrane and chloroplast stroma. Phenotype associations include aromatic amino acid biosynthesis and parthenocarpic fruit development. Related genes in other species are linked to nitrogen metabolism, protein stability, carotenoid content, chlorophyll content, and root morphology traits.
