ERF1 — Cucumis melo

Summary

MELO3C002624.2 (CmERF1) on melon chromosome 13 encodes an AP2/ERF domain-containing transcription factor with DNA-binding, transcription corepressor and coactivator activities, and protein homodimerization capability. The gene is associated with diverse biological processes including cellular responses to drought and salinity, downregulation of ethylene signaling, jasmonic acid-mediated induced systemic resistance, camalexin biosynthesis, glucosinolate metabolism, trichome and floral meristem development, and phloem or xylem histogenesis. It localizes to the nucleus, cytosol, nucleolus, and mediator complex. CmERF1 is linked to agronomically important traits such as drought tolerance, submergence tolerance, photosynthetic rate, flowering time, disease tolerance, root morphology, and stomatal opening. Studies of related genes in other species connect the family to salt tolerance, pathogen resistance, leaf senescence, and transcriptional repression.
