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) ΔX_z vs. ΔX_n 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. Straight lines correspond to .
