Brefeldin Alters the Localization of PP2AA1-GFP.
Five-day-old PP2AA1-GFP transgenic seedlings were treated for 48 h and imaged with confocal fluorescence microscopy. Images were captured using the same confocal settings and are representative of 40 roots obtained from at least five independent experiments. Arrowheads indicate nuclei. Top panel shows the transition zone; bottom panel shows the elongation zone. Bars = 50 μm.
