ERF1 — Nicotiana attenuata

Summary

A4A49_21042 (ERF1/ERF4) in coyote tobacco (Nicotiana attenuata) encodes an AP2/ERF domain-containing transcription factor with DNA binding, transcription corepressor and coactivator activities, and protein homodimerization and kinase binding capabilities. This gene is associated with nicotine anabolism, chlorophyll breakdown, seed oilbody biogenesis, trichome papilla formation and branching, downregulation of ethylene mediated signaling pathway, induced systemic resistance, jasmonic acid mediated signaling pathway, cellular response to drought, cellular salinity response, and red, far-red light phototransduction. It localizes to the nucleus, nucleolus, cytosol, and mediator complex. Associations include drought tolerance, submergence tolerance, heterosis, photosynthetic rate, chlorophyll content, flowering time, disease tolerance, auxin sensitivity, jasmonic acid content, hydrogen peroxide content, stomatal opening, root morphology, and plant growth and development traits. Studies of related genes in other species link the family to cold, salt, and drought stress tolerance, pathogen resistance, leaf senescence, root elongation, and anthocyanin production.
