Transcription factor that binds to the 5'- RRYGCCGT-3' consensus core sequence. Central longevity regulator. Negative regulator of leaf senescence. Modulates cellular H(2)O(2) levels and enhances tolerance to various abiotic stresses through the regulation of DREB2A. Expressed in roots, root caps, cotyledons, tips and margin of young leaves, senescent regions of fully expanded leaves and floral tissues, including old sepals, petals, staments, mature anthers and pollen grains. Not detected in the abscission zone of open flowers, emerging lateral roots and root meristematic zones. Up-regulated by H(2)O(2), paraquat, ozone, 3-aminotriazole and salt stress. The NAC domain includes a DNA-binding domain and a dimerization domain. Precocious senescence and lowered abiotic stress tolerance.
