ERF1 — Capsicum annuum

Summary

CaERF1 (T459_32538) on pepper chromosome PGAv.1.6.scaffold866 encodes an AP2/ERF domain-containing transcription factor with DNA-binding, transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. It is associated with seed oilbody biogenesis, trichome papilla formation and branching, cellular responses to drought and salinity, jasmonic acid anabolism, glucosinolate metabolism, red and far-red light phototransduction, ethylene-mediated signaling, and vascular tissue pattern formation. The gene is linked to fruit length and weight, plant height, flowering time, drought tolerance, submergence tolerance, disease tolerance, heterosis, flavonoid content, photosynthetic rate, stomatal opening, seed viability, and auxin sensitivity. It localizes to the nucleus, nucleolus, cytosol, cytoplasm, mediator complex, and nuclear body. Studies of related genes in other species connect the ERF1 family to cold tolerance, salt stress response, and resistance to Pseudomonas syringae.
