AIG1 — Cucumis melo

Summary

MELO3C005874.2, also known as CmAIG1, encodes a protein with abscisic acid binding, protein phosphatase inhibitor, protein kinase activator, phospholipid binding, GAP activity, lipid binding, protein kinase binding, protein phosphatase activity, protein serine/threonine phosphatase activity, signaling receptor activity, kinase binding, calcium ion binding, sequence-specific DNA binding, and transcription cis-regulatory region binding activities, and belongs to the polyketide cyclase/dehydrase, plant hormone signal, and START-like domain superfamilies. In melon, this gene is associated with the regulation of ABA, auxin, gibberellic acid, jasmonic acid, and salicylic acid signaling pathways, as well as stomatal opening, seed dormancy release, and germination. It is linked to traits including water use efficiency, transpiration rate, stomatal resistance, vegetative vigor, seed yield, sugar content, anthocyanin content, and responses to osmotic stress, nitrate, aphids, and powdery mildew. The gene product localizes to the nucleus, cytosol, plasma membrane, Golgi, and mitochondria. Studies of related genes in other species connect the family to drought resistance, salt tolerance, pathogen resistance, fruit ripening, and seed oil content.
