ERF1 — Daucus carota subsp. sativus

Summary

DcERF1 (DCAR_027309) on carrot chromosome 8 encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. In carrot, it is associated with anthocyanin synthesis, regulation of secondary metabolism, trichome papilla formation and branching, ethylene and jasmonic acid signaling, cellular responses to drought and salinity, red and far-red light phototransduction, defense response upregulation, and flower development regulation. The gene is linked to root fresh weight, adventitious rootless, root oxidative activity, ethylene and auxin sensitivity, jasmonic acid content, photosynthetic rate, flowering time, disease tolerance, and resistance to Botrytis cinerea and necrotrophic pathogens. It also associates with stomatal aperture, heat, salt and drought tolerance, lateral root development and emergence, primary root elongation, and nitrate reallocation. Studies of related genes in other species connect the family to ethylene response, fungal and bacterial resistance, and drought stress response.
