ERF1 — Daucus carota subsp. sativus

Summary

DCAR_018478 (DcERF1) on carrot chromosome 5 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, ethylene and jasmonic acid signaling, defense responses, and responses to drought, salinity, and osmotic stress. It is also linked to trichome and flower development, fruit ripening, and red/far-red light phototransduction. The gene has been connected to root fresh weight, photosynthetic rate, respiration rate, ethylene and auxin sensitivity, disease tolerance, and root morphology traits. Studies of related genes in other species link the family to ethylene response, drought and pathogen resistance, and root architecture.
