ERF1 — Daucus carota subsp. sativus

Summary

DCAR_012543 (DcERF1) on carrot chromosome 3 encodes an AP2/ERF domain-containing transcription factor with sequence-specific DNA binding and transcription coactivator activity. In carrot, DcERF1 is associated with anthocyanin synthesis, regulation of secondary metabolism, trichome papilla formation and branching, ethylene and jasmonate 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, respiration rate, photosynthetic rate, ethylene and auxin sensitivity, flowering time, disease tolerance, and root morphology traits. Associations also include resistance to Botrytis cinerea, drought, salt, and heat tolerance, stomatal aperture control, lateral root development, and nitrate reallocation. Studies of related genes in other species connect the family to ethylene response, fungal and bacterial resistance, and drought stress response.
