ERF1 — Nicotiana attenuata

Summary

A4A49_62975 (ERF1B) on chromosome 1 of coyote tobacco (Nicotiana attenuata) encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. This gene is associated with the regulation of ethylene-mediated signaling, defense responses, and phytoalexin, nicotine, ethylene, and phenylpropanoid biosynthesis. It has been linked to trichome branching and papilla formation, responses to drought, salt, red and far-red light, and flower development. Associations include traits such as disease tolerance, ethylene and auxin sensitivity, photosynthetic rate, respiration rate, hydrogen peroxide and jasmonic acid content, heterosis, and root and floral organ development. Phenotypic connections include resistance to Botrytis cinerea and necrotrophic pathogens, heat, salt, drought, and salt stress tolerance, stomatal aperture regulation, lateral root development, and ethylene and jasmonic acid signaling.
