BIF1 and BIF4 are required for patterning of primordium initiation. (A) Mature inflorescence phenotype of the double heterozygous Bif1 and Bif4 mutant. (B) Scanning electron microscope image of a young Bif1;Bif4 tassel showing lack of primordium initiation. (Scale bars, 100 μm.) (C) Confocal images of normal and Bif1;Bif4 tassels expressing ZmPIN1a-YFP fusion proteins and DR5::RFP. (D and E) Maximum projections of confocal images of wild-type and Bif1;Bif4 mutant IMs. (F and G) Confocal images of the peripheral zone of immature tassels showing up-regulation of ZmPIN1a-YFP signals in normal tassels (F, arrowheads in close-up right panel) that is missing in double Bif1;Bif4 mutants (G).
