Evidence for Divisome Localization Mechanisms Independent of the Min System and SlmA in Escherichia coli
Figure 7
Positioning of the Z-rings relative to the cell and nucleoid centers in triple deletion strains.
Composite of DAPI labelled nucleoid (red), ZipA-GFP (green) and phase contrast image in (A) ΔslmA Δmin ΔmatP, (B) ΔslmA Δmin ΔzapB, and (C) ΔslmA Δmin ΔzapA cells. Scale bar is 2 µm. (D)–(F) Distribution of distances between the Z-ring center and nucleoid center for ΔslmA Δmin ΔmatP, ΔslmA Δmin ΔzapB, and ΔslmA Δmin ΔzapA cells, respectively. (G)–(I) ΔXz vs. ΔXn in ΔslmA Δmin ΔmatP, ΔslmA Δmin ΔzapB, and ΔslmA Δmin ΔzapA cells, respectively. Data are from cells with a single compact nucleoid and a central Z-ring.
