ERF1 — Cucumis melo

Summary

MELO3C006430.2, designated CmERF1 on melon chromosome 7, encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. The gene is associated with ethylene and jasmonic acid signaling pathways, fruit ripening, and responses to drought, salt, and osmotic stress. It is linked to trichome papilla formation and branching, flower development, defense responses, and camalexin biosynthesis. Localized to the nucleus and mediator complex, CmERF1 is associated with traits including ethylene and auxin sensitivity, respiration and photosynthetic rates, flowering time, disease tolerance, and root morphology. Studies of related genes in other species link the family to ethylene response, fungal and bacterial resistance, drought response, and root architecture.
