AP2 — Cucumis melo

Summary

MELO3C009307.2 (CmAP2) on melon chromosome 5 encodes a protein with an AP2/ERF DNA-binding domain, exhibiting sequence-specific DNA binding, transcription coactivator and corepressor binding, and blue light photoreceptor activity. The gene is associated with regulation of floral organ abscission, seed development and abscission, plant epidermal cell fate specification, and starch biosynthesis. It is linked to traits including seed color, branch angle, photoperiod-sensitive flowering time, plant male sterility, shoot system elongation rate, and responses to aphids, jasmonic acid, and cytokinin. The encoded protein localizes to the nucleus, cytosol, nucleolus, Cajal body, and SCF complex. Related genes in other species are linked to trichome development, mucilage production, tannin accumulation, hybrid seed viability, and defense against pathogens and insects.
