ERF1 — Daucus carota subsp. sativus

Summary

DCAR_006575 (DcERF1) on carrot chromosome 2 encodes a protein with an AP2/ERF domain and DNA-binding, transcription coactivator and corepressor activities, and protein homodimerization capability. The gene is associated with regulation of secondary metabolism, cellular responses to drought and salinity, downregulation of ethylene-mediated signaling, jasmonic acid-mediated systemic resistance, glucosinolate metabolism, and negative regulation of gene expression. It is linked to root fresh weight, submergence tolerance, photosynthetic rate, drought tolerance, disease tolerance, flowering time, stomatal opening, auxin sensitivity, jasmonic acid content, and high-temperature stress response. The protein localizes to the nucleus, cytosol, nucleolus, and mediator complex. Studies of related genes in other species connect the family to cold and salt tolerance, pathogen resistance, anthocyanin production, leaf senescence, and root elongation.
