FIG. 3.
Fluorescence microscopy of cells with SpoIIE-GFP-associated fluorescence at sites of septation in strain IB509 from cultures harvested 2 h after cessation of logarithmic growth, photographed as described in Materials and Methods. Cells with SpoIIE-GFP localization are marked. Arrows indicate the position of SpoIIE-GFP signals. Each scale bar represents 2 μm.
