Transcriptional activator involved in the regulation of plant development and tolerance to abiotic stresses (PubMed:21069430). Acts as positive regulator of tolerance to waterlogging stress. Delays waterlogging-induced premature senescence by regulating stomatal closure and antioxidant enzyme activity. May function through ABI1-mediated abscisic acid (ABA) signaling pathway (PubMed:22661072). Involved in tissue reunion of wounded inflorescence stems. Required for the division of pith cells in the reunion process, which is dependent on polar-transported auxin and the wound-inducible hormones ethylene and jasmonate (PubMed:21911380). Binds to the GCC-box pathogenesis-related promoter element. May be involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways (By similarity). Expressed in pollen grains. Induced by salt stress (PubMed:16133218, PubMed:21069430). Induced drought stress, jasmonate (JA), salicylic acid (SA), abscisic acid (ABA) and ethylene. Down-regulated by freezing stress (PubMed:21069430). Induced by wounding in the flowering stem (PubMed:21911380). Induced by waterlogging. Belongs to the AP2/ERF transcription factor family. ERF subfamily.
