Function
Probable transcription factor required for the initiation of inflorescence trichomes in response to gibberellin (GA). Acts upstream of GIS, GIS2, ZFP8 and the trichome initiation regulators GL1 and GL3 (PubMed:21803862, PubMed:22301962). Binds the promoter region of ZFP8, which may be a direct target of ZPF5 (PubMed:21803862). Is not involved in the regulation of trichome branching (PubMed:22301962). Modulates root hair initiation and elongation in response to cytokinin and ethylene signals by directly promoting expression of the CAPRICE (CPC) gene (PubMed:22762888).
