ERF1 — Cucumis melo

Summary

MELO3C015737.2, designated CmERF1 (also known as ERF1, ERF1B, ERF15), encodes an AP2/ERF domain-containing transcription factor on melon chromosome 2. The protein exhibits sequence-specific DNA binding and transcription coactivator activity, localizes to the nucleus, and is associated with the mediator complex. CmERF1 is associated with ethylene and jasmonic acid signaling, fruit ripening, cellular responses to drought and salinity, camalexin biosynthesis, trichome branching and papilla formation, red and far-red light phototransduction, and regulation of flower development and defense responses. The gene has been connected to traits including ethylene and auxin sensitivity, photosynthetic and respiration rates, flowering time, disease tolerance, and root and hypocotyl morphology. Related genes in other species link the family to ethylene response, fungal and bacterial resistance, drought response, and root architecture.
