ERF1 — Nicotiana attenuata

Summary

A4A49_30642 (ERF1/ERF15) in Nicotiana attenuata encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. It is associated with the regulation of ethylene-mediated signaling, defense responses, and phytoalexin and nicotine biosynthesis. The gene has been linked to trichome papilla formation and branching, autotrophy, and responses to red and far-red light, drought, and salinity. It is localized to the nucleus and the Mediator complex. Associations with traits include ethylene and auxin sensitivity, hydrogen peroxide content, photosynthetic rate, respiration rate, flowering time, and disease tolerance. The gene is also connected to heterosis, adventitious rootless, root oxidative activity, and floral organ development. Related genes in other species link the family to pathogen resistance, drought tolerance, and ethylene response.
