Transcription activator involved in responses to drought stress and salt stress. Transactivates the stress response genes LEA19 and PM19L. Expressed in roots (PubMed:18813954, PubMed:19135985). Expressed at low levels in leaves, stems and panicles (PubMed:19135985). Induced by salt and cold stresses (PubMed:18813954, PubMed:19135985). Induced by drought stress (PubMed:19135985). The NAC domain includes a DNA binding domain and a dimerization domain.
