(A) ftsZL169R suppresses the cell division defects of a strain lacking ZapA and ZapC. Representative phase contrast micrographs of a ΔzapAC strain in an ftsZWT or ftsZL169R background. Scale as in Figure 1A. Average cell length ± standard deviation are indicated for both strains. (B) ftsZL169R suppresses defects in divisome components. Spot dilutions of indicated ts strains with empty pKG116 or with plasmid expressing (0.1 μM sodium salicylate) ftsZWT or ftsZL169R at permissive (30ºC) or restrictive (37º or 42ºC) temperatures.
