Fluorescence of yeast vitally stained with ethidium bromide and propidium iodideDA Corliss and WE White
Both ethidium bromide and propidium iodide stain growing yeast. As visualized in the fluorescence microscope, ethidium stains the nucleus and cytoplasm in wild type yeast and in those grown in 10% dextrose, with brightly fluorescent cytoplasmic granules being present in both. Under the latter conditions, the mitochondria are repressed but not absent. In rho 0 cells, in which the mitochondrial DNA is absent, ethidium appears to bind to the cell wall or membrane preferentially with no cytoplasmic granules being visible. In all cell types, propidium appears to bind the cell wall or membrane with no cytoplasmic granules being visible in any cell. The staining patterns thus suggest greater differences in the binding of these two types to mitochondrial DNA in situ than is suggested by their in vitro behavior. These differences in binding could explain their different mutagenic capacities..
