ERF1 — Nicotiana attenuata

Summary

A4A49_40871 (ERF1B) on chromosome 11 of coyote tobacco (Nicotiana attenuata) encodes a DNA-binding transcription factor with an AP2/ERF domain. It exhibits transcription coactivator activity and sequence-specific DNA binding. This gene is associated with the regulation of ethylene-mediated signaling, defense responses, and phytoalexin biosynthesis. It is linked to nicotine and phenylpropanoid anabolism, trichome papilla formation and branching, and responses to drought, salinity, and red/far-red light. Associations with flowering time, floral organ development, and heterosis are noted. The gene is also linked to traits including disease tolerance, pathogen resistance (including to Botrytis cinerea), heat, salt, and drought tolerance, as well as stomatal aperture, photosynthetic rate, and root morphology traits. It localizes to the nucleus and is linked to the Mediator complex.
