ACS7 — Cucumis sativus

Summary

CSA_1G580750 (ACS7) on cucumber chromosome 1 encodes a 1-aminocyclopropane-1-carboxylate synthase, an enzyme with pyridoxal phosphate-dependent transaminase activity. The gene is associated with sex differentiation, carpel development, flower morphogenesis, and organ growth regulation. It is linked to negative regulation of ethylene biosynthesis, alternative respiration, and responses to calcium ions. Associations include fruit length, shape, and size, as well as adventitious root development, lateral root number, submergence tolerance, and high temperature stress response. The gene product localizes to the cytosol, plasma membrane, mitochondria, Golgi, and vacuole. Studies of related genes in other species link the ACS7 family to ethylene production, organ size, lateral root initiation, and responses to ABA, salt, and darkness.
