FtsZ-GFP localization in ΔpodJAt cells. FtsZ-GFP (green) localizes in unipolar (A), bipolar (B), subpolar (C), unipolar and subpolar (D), polar cluster (E), unipolar and Z-ring (F), Z-ring (G), contracting Z-ring (H), multiple-Z-ring (I), and multiple-sidewall-focus (J) patterns in ΔpodJAt cells. Percentages of ΔpodJAt cells (n = 252) and WT (12) cells (in parentheses) showing different FtsZ-GFP localizations are shown beneath representative images. Localizations seen in notably higher percentages of WT cells than ΔpodJAt cells are highlighted by red rectangles, and localizations seen in notably higher percentages of ΔpodJAt cells than WT cells are highlighted by blue rectangles. Bar, 3 μm.
