SAT1 — Daucus carota subsp. sativus

Summary

DCAR_011989 (SAT1) on carrot chromosome 3 encodes a serine acetyltransferase, an enzyme with L-serine O-acetyltransferase and cysteine synthase activities. The gene is associated with sulfate assimilation, cysteine anabolism, and anthocyanin metabolism, including regulation of anthocyanin anabolism and anthocyanin acylation. SAT1 has been linked to pigmentation, responses to light intensity, oxidative stress, salinity response, response to cadmium, and response to zinc, as well as pollen tube development and growth, double fertilization, and negative regulation of leaf senescence. The encoded protein localizes to multiple chloroplast compartments, the thylakoid lumen and membrane, the apoplast, and endomembrane system components. Associations with agronomic traits include sulfur content, submergence tolerance, cadmium concentration, aphid response trait, trichome morphology trait, leaf senescence trait, flowering time trait, disease tolerance, and plant growth and development trait.
