AP2 — Cucumis melo

Summary

MELO3C014261.2 (CmAP2) on melon chromosome 9 encodes a DNA-binding transcription factor with an AP2/ERF domain, annotated with transcription corepressor and coactivator activity, blue light photoreceptor activity, and protein homodimerization. The gene is associated with the regulation of floral organ abscission, seed abscission and development, endosperm development, plant epidermal cell fate specification, starch biosynthesis, and triterpenoid anabolism. It is linked to photoperiod-sensitive flowering time, seed color and coat morphology, branch angle, plant male sterility, shoot system elongation, whole plant size, and responses to aphids, thrips, jasmonic acid, gibberellic acid, cytokinin, and potassium. Localization evidence places the product in the nucleus, cytosol, nucleolus, Cajal body, and SCF complex. Related genes in other species are linked to trichome development, mucilage production, tannin accumulation, drought tolerance, and defense against pathogens and insects.
