Probable transcription factor required for the initiation of inflorescence trichomes in response to gibberellin and cytokinin. Is not involved in the regulation of trichome branching. Is functionally equivalent to ZFP8. Expressed in inflorescence meristems, floral meristems and stem epidermis. By cytokinin and gibberellin. Reduced trichome production on cauline leaves, stem branches and sepals.
