Cellular Localization of WDR5a and the Expression Pattern of WDR5a.

(A) Nuclear localization of the WDR5a-GFP fusion protein in roots of transgenic Arabidopsis seedlings. The blue 4',6-diamidino-2-phenylindole (DAPI) staining indicates nuclei. WDR5a-GFP and DAPI fluorescence was imaged using a laser scanning confocal microscope. Bars = 50 μm.

(B) Spatial expression patterns of the GUS reporter gene translationally fused to FLC or WDR5a in seedlings. The lines containing FLC-GUS carry a null flc allele. Bars = 1.0 mm.
