AtERF71/HRE2 transcription factor mediates osmotic stress response as well as hypoxia response in Arabidopsis

► AtERF71/HRE2 mediates the response to osmotic stress such as high salt and drought. ► AtERF71/HRE2 is involved in oxidative stress response. ► AtERF71/HRE2 might not be involved in the defense response to pathogens. ► AtERF71/HRE2 has a transcription activation activity in its C-terminal region.
