False-color two-dimensional SR reconstruction of FtsZ-Dendra2 (red) in live C. crescentus cells overlaid on a reversed contrast white-light transmission image of the cells. The red box highlights the midplane of a stalked cell; here, the arrow points to the FtsZ ring typically observed in stalked cells. The blue box highlights the midplane of a pre-divisional cell; here, the arrow points to the FtsZ constriction typically observed in pre-divisional cells. Scale bar: 2 μm.
