ERF3 — Nicotiana attenuata

Summary

A4A49_42272 (ERF3/ERF4) on chromosome 8 of coyote tobacco (Nicotiana attenuata) encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription cis-regulatory region binding activity. This nuclear protein is associated with ethylene-mediated signalling, leaf senescence and development, chlorophyll breakdown, cell death, defense response, and protein synthesis. The gene is linked to leaf chlorosis, ethylene sensitivity, and chlorophyll content. Related genes in other species connect the family to drought tolerance, salt response, germination rate, seed maturation, fruit size, sugar content, shoot dry weight, proline content, and bacterial wilt resistance.
