ERF1 — Capsicum annuum

Summary

CaERF1 (T459_14836) on pepper chromosome 5 encodes a DNA-binding transcription factor of the AP2/ERF family, with sequence-specific DNA binding and transcription coactivator activity. The gene is associated with fruit ripening, fruit length and weight, flowering time, plant height, and heterosis. It is linked to responses to drought, salt, osmotic stress, and heat, as well as disease tolerance, pathogen resistance, and resistance to Botrytis cinerea. Associations include ethylene and jasmonic acid signaling, defense response regulation, trichome formation, red and far-red light phototransduction, and nitrate reallocation. The encoded protein localises to the nucleus and the mediator complex. Studies of related genes in other species connect the family to ethylene response, fungal and bacterial resistance, drought response, and root architecture.
