Fig. 6. Subcellular localization of the APSI1 protein in Arabidopsis roots. Confocal images of Arabidopsis roots expressing GFP – APSI1 protein. Nuclei were identified by DAPI staining. Fluorescence signals were detected using a laser scanning confocal fluorescence microscope. GFP and DAPI images were merged. Scale bars are 20 μm. The experiments were repeated at least 3 times using plants grown independently, and the representative results are shown.
