ERF1 — Daucus carota subsp. sativus

Summary

DCAR_005691, designated DcERF1 on carrot chromosome 2, 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 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, photosynthetic rate, respiration rate, ethylene and auxin sensitivity, flowering time, disease tolerance, and organ identity. Associations also include resistance to Botrytis cinerea, drought, salt, and heat tolerance, lateral root development and emergence, primary root elongation, nitrate reallocation, and camalexin biosynthesis. Related genes in other species are linked to ethylene response, fungal and bacterial resistance, drought response, and root architecture.
