ERF1 — Nicotiana attenuata

Summary

A4A49_36848 (ERF1B) on coyote tobacco (Nicotiana attenuata) chromosome scaffold04680 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 and nicotine biosynthesis. It has been linked to trichome branching and papilla formation, responses to red and far-red light, drought and salinity stress, and phenylpropanoid and ethylene metabolism. ERF1B is also associated with traits including disease tolerance, pathogen resistance, flowering time, photosynthetic rate, hydrogen peroxide content, jasmonic acid content, auxin sensitivity, heterosis, and root and floral organ development. The protein localizes to the nucleus and the mediator complex, and is associated with jasmonic acid signaling and hormone metabolism pathways.
