AP2 — Cucumis melo

Summary

MELO3C007572.2 (CmAP2) on melon chromosome 9 encodes a DNA-binding transcription factor with transcription corepressor activity, belonging to the AP2/ERF domain family. It is associated with the regulation of floral organ abscission, seed abscission, flower formation, and specification of floral organ identity. The gene is linked to negative regulation of transcription by RNA polymerase II, gibberellic acid homeostasis, meristem maintenance, and regulation of endosperm and seed development. Associations also include starch biosynthesis, galactose metabolism, triterpenoid and flavonoid anabolism, and vascular tissue patterning. CmAP2 is associated with flowering time, fruit ripening, lycopene accumulation, photosynthetic rate, and seed yield. Studies of related genes in other species link the family to floral meristem determinacy, ovule identity, and seed coat mucilage production.
