ACS10 — Cucumis melo

Summary

MELO3C005597.2, designated CmACS10 on melon chromosome 10, encodes a protein with aminotransferase and 1-aminocyclopropane-1-carboxylate synthase activities, binding pyridoxal phosphate and DNA. It is associated with ethylene biosynthesis, fruit ripening, sugar-mediated signalling, and downregulation of seed germination. The gene has been linked to powdery mildew resistance in melon and to responses to abscisic acid, gibberellin, salinity, and drought. Annotated associations include traits such as iron content, nitrate sensitivity, cadmium concentration, phosphorus uptake, water use efficiency, anthocyanin content, leaf senescence, flowering time, and root meristem development. The encoded protein localises to the nucleus and amyloplast membrane. Studies of related genes in other species connect the family to abscisic acid signalling, seed dormancy, osmotic stress tolerance, and iron transport.
