ERF1 — Capsicum annuum

Summary

CaERF1 (T459_11249) on pepper chromosome 4 encodes an AP2/ERF domain-containing protein with DNA-binding transcription factor activity, transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. It is associated with responses to drought, salinity, red and far-red light, ethylene and jasmonic acid signaling, glucosinolate metabolism, seed oilbody biogenesis, trichome formation, and vascular tissue patterning. The gene is linked to traits including fruit length and weight, plant height, flowering time, photosynthetic rate, drought and submergence tolerance, disease tolerance, seed viability, heterosis, flavonoid content, and auxin sensitivity. It localizes to the nucleus, nucleolus, cytosol, and mediator complex. Studies of related genes in other species connect the ERF1 family to cold, salt, and drought stress tolerance, pathogen resistance, leaf senescence, root elongation, and anthocyanin production.
