Probable transcription factor that regulates organogenesis during transition from the vegetative to the reproductive phase. Regulates the expression of CYP78A11/PLA1, HD3A and MADS1 during reproductive development in rice. May act upstream of CYP78A11/PLA1 during panicle development. Acts independently of the photoperiodic and gibberellin signaling pathways. Belongs to the type IV zinc-finger family. Class B subfamily.
