ERF1 — Nicotiana attenuata

Summary

A4A49_25134 (ERF1B) in Nicotiana attenuata encodes a protein with an AP2/ERF domain and is annotated as a transcription coactivator with DNA binding and transcription factor activity. It is associated with the regulation of ethylene-mediated signaling, defense responses, and phytoalexin, nicotine, and phenylpropanoid biosynthesis. The gene is linked to disease resistance, trichome branching and papilla formation, responses to drought, salinity, and red/far-red light, and flower development. It localizes to the nucleus and the Mediator complex. Associations with traits such as heterosis, photosynthetic rate, ethylene and auxin sensitivity, jasmonic acid content, and flowering time have been noted. Related genes in other species connect the family to pathogen resistance, stress tolerance, root architecture, and fruit development.
