ERF1 — Capsicum annuum

Summary

CaERF1 (T459_11245) on pepper chromosome 4 encodes an ethylene-responsive transcription factor 12 with an AP2/ERF domain, possessing DNA-binding, transcription coactivator and corepressor activities, and kinase-binding and homodimerization functions. This gene is associated with cellular responses to drought and salinity, jasmonic acid-mediated systemic resistance, glucosinolate metabolism, seed oilbody biogenesis, trichome formation and branching, red-light phototransduction, flower development, and vascular tissue patterning. It localizes to the nucleus, cytosol, nucleolus, and mediator complex. Associations include fruit length and weight, plant height, flowering time, photosynthetic rate, drought and submergence tolerance, disease tolerance, heterosis, flavonoid content, seed viability, root oxidative activity, auxin sensitivity, and stomatal opening. Studies of related genes in other species link the family to cold, salt, and drought stress tolerance, pathogen resistance, leaf senescence, and anthocyanin production.
