AGT2 — Daucus carota subsp. sativus

Summary

DCAR_014252 (DcAGT2) on carrot chromosome 4 encodes a pyridoxal phosphate-dependent aminotransferase with multiple annotated activities, including L-ornithine transaminase, N2-acetylornithine 5-aminotransferase, alanine-glyoxylate transaminase, and 4-aminobutyrate:pyruvate transaminase. The gene is associated with glyoxylate breakdown, photorespiration, arginine and biotin anabolism, and L-proline biosynthesis. It is linked to responses to flooding, heat, oxidative stress, brassinosteroid, jasmonic acid, auxin, and nitrogen levels. The encoded protein is predicted to localize to mitochondria, chloroplast stroma, vacuole, and cytoplasm. Studies of related genes in other species connect the family to drought tolerance, seed dormancy, pollen fertility, and osmotic stress sensitivity.
