ERF1 — Nicotiana attenuata

Summary

A4A49_37357 (ERF1B) in coyote tobacco (Nicotiana attenuata) encodes a DNA-binding transcription factor with an AP2/ERF domain. It is associated with the regulation of ethylene-mediated signaling, defense responses, and phytoalexin and nicotine biosynthesis. The gene has been linked to trichome branching and papilla formation, as well as responses to drought, salinity, and red/far-red light. It is also connected to flower development regulation and phenylpropanoid metabolism. Traits associated with ERF1B include disease tolerance, pathogen resistance, ethylene sensitivity, and photosynthetic rate. Additionally, it has been linked to heterosis, hydrogen peroxide content, and root and floral organ development traits. The gene product localizes to the nucleus and the mediator complex.
