ERF1 — Nicotiana attenuata

Summary

A4A49_13998 (ERF1/ERF4) in coyote tobacco (Nicotiana attenuata) encodes a DNA-binding transcription factor with AP2/ERF domain and transcription corepressor and coactivator activities. It is associated with nicotine anabolism, chlorophyll breakdown, seed oilbody biogenesis, trichome papilla formation and branching, cellular responses to drought and salinity, ethylene and jasmonic acid signaling, and defense response upregulation. The gene is linked to traits including drought tolerance, submergence tolerance, heterosis, photosynthetic rate, chlorophyll content, flowering time, disease tolerance, hydrogen peroxide and jasmonic acid content, auxin sensitivity, high temperature stress response, stomatal opening, and root and shoot development. Studies of related genes in other species link the family to salt tolerance, cold and heat stress responses, anthocyanin production, leaf senescence, and resistance to Pseudomonas syringae and viruses.
