Probably acts as a transcriptional activator and may be involved in disease resistance pathways (By similarity). Binds to the GCC-box pathogenesis-related promoter element. Involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways mediated by ethylene, that seems to depend on a protein kinase cascade and to be influenced by methyl-jasmonate. Expressed in roots and at low levels in buds and leaves. Highly expressed in cell culture, especially during the exponential phase. Highly and transiently expressed in tobacco mosaic virus (TMV) infected leaves. Induced by methyl-jasmonate (MeJA), and by ethephon (ethylene-releasing compound) in buds and to lower extent in leaves. Quickly and transiently induced by salicylic acid (SA). Strongly induced by wounding, independently of ethylene, and through a de-novo-protein-synthesis-independent regulation. Wound induction is reduced by MeJA. Also induced by acetyl salicylic acid (ASA), cycloheximide, auxin (2,4-D), and benzoic acid (BA) but seems to not be influenced by 4-hydroxybenzoic acid (4HBA), thiamine, H(2)O(2) or abscisic acid (ABA). The AP2/ERF domain binds specifically to the 5'-GCCGCC-3' motif. The affinity of this binding is higher if the seventh amino-acid of this domain is basic (By similarity). Belongs to the ethylene-response factor family. Class 1 subfamily.
