VER2 and O-GlcNAc Signaling Figure 6. Motility of VER2-GFP fusion protein in Arabidopsis leaf epidemis and veins. (A) VER2-GFP involved nuclear movement in epidermal cells. PI-stained cell wall was shown in the red channel. (B) VER2-GFP involved nuclear movement in vein cells. (C) Movement of punctate- located VER2-GFP in leaf epidermal cells. (D) Temporal dynamics of VER2-GFP targeted to punctuate structures in vein cells, showing merged images of fluorescence and corresponding transmitted images. n, nuclei; cw, cell wall.
