ERF1 — Nicotiana attenuata

Summary

A4A49_15465 (ERF1/ERF4) in coyote tobacco (Nicotiana attenuata) encodes a protein with an AP2/ERF domain, annotated with DNA binding, transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. This gene is associated with nicotine anabolism, chlorophyll breakdown, seed oilbody biogenesis, trichome papilla formation and branching, autotrophy, cellular responses to drought and salinity, downregulation of ethylene-mediated signaling, jasmonic acid-mediated systemic resistance, glucosinolate metabolism, floral meristem determinacy, and red/far-red light phototransduction. It localizes to the nucleus, cytosol, nucleolus, and mediator complex. Associations include hydrogen peroxide content, submergence tolerance, heterosis, leaf chlorosis, photosynthetic rate, drought tolerance, disease tolerance, jasmonic acid content, stomatal opening, flowering time, and root morphology. Related genes in other species are linked to salt tolerance, cold and heat stress responses, leaf senescence, and resistance to Pseudomonas syringae and viruses.
