ACC4 — Cucumis melo

Summary

MELO3C019008.2 (CmACC4) on melon chromosome 8 encodes a 1-aminocyclopropane-1-carboxylate synthase, an enzyme with pyridoxal phosphate binding and transaminase activity. The gene is associated with sex determination and female flower development in melon, and has been connected to fruit ripening, fruit shape, fruit elongation, and yield traits. It is linked to ethylene biosynthesis and signaling pathways, as well as responses to organophosphorus, nitrogen starvation, and potassium ions. Associations also include root growth, lateral root formation, root hair development, shoot regeneration, flowering time, leaf senescence, photosynthetic rate, and stress responses including low temperature, ozone, and hypoxia. The gene product localizes to multiple cellular compartments including the cytosol, plastid, cell wall, and plasmodesmata.
