AP2 — Cucumis sativus

Summary

CsAP2 (CSA_4G292470) on cucumber chromosome 4 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 activity. It is associated with regulation of floral organ abscission, seed abscission, sex determination, seed development, and downregulation of photosynthesis. The gene is linked to traits including fruit length, seed color, starch grain synthesis, photoperiod-sensitive flowering time, plant male sterility, and aphid and jasmonic acid response. It localizes to the nucleus, cytosol, nucleolus, Cajal body, and SCF complex. Related genes in other species are linked to trichome development, seed mucilage production, drought tolerance, and defense against pathogens and insects.
