ERF1 — Capsicum annuum

Summary

CaERF1 (T459_29252) on pepper chromosome 12 encodes a DNA-binding transcription factor with an AP2/ERF domain. It is annotated with transcription coactivator activity and sequence-specific DNA binding. This gene is associated with fruit ripening, fruit length, fruit weight, and respiration rate, as well as jasmonic acid signaling and anabolism, ethylene-mediated signaling, and responses to drought, salinity, and osmotic stress. It has been linked to disease tolerance, resistance to Botrytis cinerea and necrotrophic pathogens, heat and salt tolerance, and defense response upregulation. Additional associations include trichome papilla formation and branching, flower development regulation, red and far-red light phototransduction, seed viability, plant height, and heterosis. The gene product localizes to the nucleus and the mediator complex. Studies of related genes in other species link the family to ethylene response, fungal resistance, and drought response.
