showed a trendp < 0.0001
The observations of ΔftsZ1 , ΔcetZ5 , and ΔcetZ6 showed a trend of cells above the 2.5 μm threshold starting off significantly longer than the parental cells at the 1 h mark ( p < 0.0001), but they decreased in size and significance by the 6 h timepoint. ΔcetZ2 cells showed no significant difference in length at any of the timepoints compared to the parental cells, whereas ΔcetZ4 cells started off longer but after 1 h adopted a more parental-like phenotype.
