AP2 — Cucumis sativus

Summary

CsAP2 (CSA_2G279250) on cucumber chromosome 2 encodes a DNA-binding transcription factor with transcription corepressor activity, belonging to the AP2/ERF domain superfamily. It 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 metabolism, and demethylation. The gene is linked to fruit length, flowering time, chlorophyll content, photosynthetic rate, jasmonic acid content, root morphology, plant growth, and shoot apical meristem development. Related genes in other species are linked to floral meristem determinacy, stem cell maintenance, ovule identity, seed yield, and somatic embryogenesis.
