ERF1 — Daucus carota subsp. sativus

Summary

DcERF1 (DCAR_002323) on carrot chromosome 1 encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. It is associated with the regulation of secondary metabolism, including anthocyanin synthesis, and with ethylene and jasmonic acid signaling pathways. The gene has been linked to cellular responses to drought, salinity, and osmotic stress, as well as to defense responses, pathogen resistance, and tolerance to Botrytis cinerea. Associations also include root fresh weight, root morphology, flowering time, fruit ripening, photosynthetic rate, and responses to red and far-red light. DcERF1 localizes to the nucleus and the mediator complex. Studies of related genes in other species connect the family to ethylene response, drought tolerance, and resistance to fungal and viral pathogens.
