AP2 — Cucumis melo

Summary

MELO3C011722.2 (CmAP2) encodes a DNA-binding transcription factor containing an AP2/ERF domain, with activities including sequence-specific DNA binding, transcription corepressor and coactivator activity, blue light photoreceptor activity, and protein homodimerization. In melon, this gene is associated with the regulation of floral organ abscission, seed abscission and development, endosperm development, plant epidermal cell fate specification, starch biosynthesis, and negative regulation of cellulose anabolism. It is also linked to photoentrainment of the circadian clock, jasmonic acid/ethylene-dependent systemic resistance, triterpenoid anabolism, and proteasomal protein catabolic processes. The encoded protein localizes to the nucleus, cytosol, nucleolus, Cajal body, and SCF complex. Associations with agronomic traits include seed color, branch angle, plant male sterility, photoperiod-sensitive flowering time, aphid and insect damage response, potassium sensitivity, and starch grain synthesis.
