ACS2 — Solanum lycopersicum

Summary

SOLYC08G008110.2, designated ACS2 on tomato chromosome 8, encodes a protein with aminotransferase domains and pyridoxal phosphate binding capacity, and exhibits 1-aminocyclopropane-1-carboxylate synthase and transaminase activities. The gene is associated with ethylene anabolism, as well as lycopene and carotenoid anabolism, pigmentation, fruit color, and lycopene content. It has also been connected to chlorophyll anabolism and breakdown, photomorphogenesis, abscission, cellular auxin homeostasis, demethylation, protein destabilization and breakdown, amino acid metabolism, developmental processes, syngamy, secretion, NO storage, and traits including stem diameter, fruit shape, starch content, germination rate, and seed maturation. Studies of related genes in other species link the family to 1-aminocyclopropane-1-carboxylate synthase activity (EC 4.4.1.14).
