ACS7 — Cucumis melo

Summary

MELO3C015444.2 (ACS7) on melon chromosome 3 encodes a 1-aminocyclopropane-1-carboxylate synthase, a pyridoxal phosphate-dependent aminotransferase (EC 4.4.1.14). In melon, ACS7 is associated with sex determination. The gene is associated with fruit ripening, flower development, lateral root formation, and responses to auxin, brassinosteroids, and defense. It is linked to ethylene anabolism and its negative regulation, as well as cytokinin signaling, secondary metabolism, and induced systemic resistance. Associations include fruit shape, leaf senescence, flowering time, disease tolerance, submergence tolerance, nitrate uptake, and abscisic acid concentration. The encoded protein localizes to the cytosol, cytoplasm, plasma membrane, mitochondria, Golgi, and vacuole. Studies of related genes in other species link the family to ethylene production, lateral root initiation, and responses to salt, ABA, and darkness.
