ACS1 — Solanum lycopersicum

Summary

SOLYC01G095080.3 (ACS1, also known as ACS2) encodes a 1-aminocyclopropane-1-carboxylate synthase, a pyridoxal phosphate-dependent enzyme. The gene is associated with fruit ripening in tomato, as well as lycopene and carotenoid breakdown, pigment metabolism, and ethene metabolism. It has been linked to numerous traits including fruit firmness, fruit color, carotene content, amino acid content, sucrose content, flavonoid content, seed yield, vegetative vigor, root fresh weight, drought sensitivity, and responses to waterlogging, salt stress, cadmium, hypoxia, and nitrogen deficiency. The gene product localizes to the cytosol, plastid, mitochondria, plasmalemma, plant-type cell wall, vacuole, and Golgi complex. Studies of related genes in other species connect the family to sex determination, leaf senescence, disease resistance, and abiotic stress tolerance.
