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. Highly expressed in inflorescences. Expressed in vascular bundles of root stele within the elongation zones, of elongating upper internodes and of the junctions of leaf blades and sheaths. Expressed predominantly in the bract primordia during panicle development. Reduced plant size. Delayed transition from vegetative to reproductive growth. Reduced panicle size with overgrown bracts at their bases. Belongs to the type IV zinc-finger family. Class B subfamily.
