ACS1 — Cucumis melo

Summary

MELO3C021182.2 (CmACS1) on melon chromosome 12 encodes a 1-aminocyclopropane-1-carboxylate synthase, a pyridoxal phosphate-dependent aminotransferase. The gene is associated with ethylene production and sensitivity, abscission, fruit size, leaf senescence, seed dormancy, and shoot branching. It has been linked to responses to freezing, cold acclimation, waterlogging, hypoxia, salt stress, cadmium, iron deficiency, nitrogen and phosphate starvation, and mechanical stimuli. Associations also include regulation of stomatal movement, abscisic acid-mediated signalling, root and pistil development, vegetative vigour, photosynthetic rate, respiration, anthocyanin content, and resistance to Verticillium wilt, nematodes, and bacterial pathogens. The encoded protein is localised to the cytosol, plasma membrane, plastid, mitochondria, Golgi, vacuole, cell wall, and plasmodesmata.
