AP2 — Cucumis sativus

Summary

CsAP2 (CSA_6G491020) in cucumber (Cucumis sativus) encodes a DNA-binding transcription factor with transcription corepressor activity, belonging to the AP2/ERF domain superfamily. The gene is associated with the regulation of flower formation, floral organ identity and abscission, sex determination, seed development and abscission, endosperm development, starch biosynthesis, photosynthesis and its downregulation, auxin biosynthesis, the TCA cycle, valine anabolism, demethylation, and regeneration. It localises to the nucleus, cytoplasm, and transcription regulator complex. CsAP2 is linked to fruit length, flowering time, chlorophyll content, photosynthetic rate, jasmonic acid content, root morphology, shoot apical meristem development, and plant growth. Related genes in other species are associated with floral development, seed yield, ovule number, and Fusarium wilt resistance.
