Fig. 6. Peroxisome abundance in cells with mitochondrial dysfunction. (A) Cells expressing GFP-PTS1 were grown on 2% glucose medium to log phase and representative images were captured. Images are flattened z-stacks. Top rows, GFP-PTS1 fluorescence; bottom rows, phase-contrast images showing outline of cells. Scale bar: 5 µm. (B) Peroxisome numbers were counted from images of >100 budding cells for each strain.
