AIG1 — Cucumis melo

Summary

MELO3C006033.2 (CmAIG1) on melon chromosome 7 encodes a protein with abscisic acid binding, protein kinase activator activity, and protein phosphatase inhibitor activity, and belongs to the polyketide cyclase/dehydrase and START-like domain superfamilies. The gene is associated with regulation of abscisic acid, auxin, salicylic acid, jasmonic acid, and gibberellic acid mediated signaling pathways, as well as stomatal opening, seed dormancy release, and seed germination. It is linked to drought resistance, salt stress response, osmotic stress tolerance, water use efficiency, transpiration rate, vegetative vigor, seed yield, anthocyanin content, sugar content, and responses to aphids, powdery mildew, and other pathogens. Localization evidence connects the product to the nucleus, cytosol, plasma membrane, Golgi, and mitochondria. Studies of related genes in other species link the family to fruit ripening, leaf senescence, cold tolerance, and nematode resistance.
