ERF1 — Daucus carota subsp. sativus

Summary

DCAR_013121, designated DcERF1 on carrot chromosome 4, encodes a protein with AP2/ERF and DNA-binding domains, annotated with transcription coactivator and corepressor activities, kinase binding, and protein homodimerization. The gene is associated with regulation of secondary metabolism, cellular responses to drought and salinity, ethylene-mediated signaling, and induced systemic resistance via jasmonic acid. It has been linked to root fresh weight, submergence tolerance, photosynthetic rate, drought tolerance, disease tolerance, flowering time, and stomatal opening. Localization evidence places the product in the nucleus, cytosol, nucleolus, and mediator complex. Studies of related genes in other species connect the family to salt tolerance, cold and heat stress responses, leaf senescence, pathogen resistance, and transcriptional repression.
