ACS — Cicer arietinum

Summary

GmACS, located on chickpea chromosome 16, encodes a protein with 1-aminocyclopropane-1-carboxylate synthase activity, along with transaminase, acetate-CoA ligase, and medium-chain fatty acid-CoA ligase activities, and binds pyridoxal phosphate and ATP. The gene is associated with ethylene anabolism, acetate metabolism, response to jasmonic acid, cold acclimation, response to freezing, fruit ripening, and regulation of abscisic acid-mediated signaling. It is linked to traits including seed yield, vegetative vigor, leaf senescence, root development, stomatal resistance, disease tolerance, oxidative stress response, and low temperature stress response. The product localizes to the plastid, cytosol, plant-type cell wall, and plasmodesma. Studies of related genes in other species connect the family to ethylene production, resistance to necrotrophic infection, salt stress tolerance, and cadmium tolerance.
