Promotes cuticle formation by inducing the expression of enzymes involved in wax biosynthesis. Probably acts as a transcriptional activator. 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). Found in all organs, mostly in veins, epidermis and trichome bases. Specific expression in lateral root tips. By wounding in cauline leaves, stems, and siliques, but not in rosette leaves. May be due to a competing acceptor splice site. Belongs to the AP2/ERF transcription factor family. ERF subfamily.
