ERF1 — Daucus carota subsp. sativus

Summary

DCAR_021257 (DcERF1) on carrot chromosome 6 encodes an AP2/ERF domain-containing protein with DNA binding, transcription coactivator and corepressor activities, and protein homodimerization activity. The gene is associated with regulation of secondary metabolism, glucosinolate metabolism, and cellular responses to drought and salinity. It is linked to root fresh weight, drought tolerance, submergence tolerance, photosynthetic rate, flowering time, disease tolerance, and auxin sensitivity. Additional associations include floral meristem determinacy, trichome branching, phloem or xylem histogenesis, and red/far-red light phototransduction. The protein localizes to the nucleus, nucleolus, cytosol, and mediator complex. Related genes in other species link the family to salt tolerance, cold stress response, pathogen resistance, leaf senescence, and transcriptional repression.
