AIG1 — Cucumis melo

Summary

MELO3C026930.2 (CmAIG1) on melon chromosome 7 encodes a protein with abscisic acid binding, protein phosphatase inhibitor activity, and protein kinase activator activity, placing it in the START-like domain superfamily and polyketide cyclase/dehydrase family. The gene is associated with regulation of abscisic acid and auxin mediated signaling, stomatal opening, seed dormancy release and germination, and defense responses to bacteria. It has been linked to numerous agronomic traits including water use efficiency, transpiration rate, stomatal resistance, seed yield, sugar and anthocyanin content, shoot branching, lateral root length, and responses to salinity, osmotic stress, aphids, and powdery mildew. Studies of related genes in other species connect the family to ABA sensitivity, stomatal response, cold tolerance, seed oil content, and resistance to green peach aphid and biotrophic pathogens.
