ERF1 — Nicotiana attenuata

Summary

A4A49_30641 (ERF1/ERF15) in Nicotiana attenuata encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity, localized to the nucleus. This gene is associated with the regulation of ethylene and jasmonic acid signaling pathways, phytoalexin and nicotine biosynthesis, phenylpropanoid metabolism, and responses to drought, salt, and red light. It has been linked to traits including disease tolerance, pathogen resistance (notably to Botrytis cinerea), heat, drought, and salt tolerance, as well as photosynthetic rate, flowering time, root morphology, lateral root development, and auxin sensitivity. Additional associations include heterosis, hydrogen peroxide content, and floral organ development. Studies of related genes in other species link the family to ethylene response, resistance to fungal and bacterial pathogens, drought response, and root architecture.
