Table 1. Summary of sporulation septa position in wild type and mutant strains.

Strain	Cell length	Distance from	Relative distance from
	± SD [μm]	the pole ± SD [μm]	the pole ± SD [%]
wt	2.46 ± 0.4	0.42 ± 0.13	17.1 ± 4.3
ΔspoIIE	3.94 ± 0.7	0.89 ± 0.17	23.2 ± 5.3
ΔrefZ	2.54 ± 0.4	0.52 ± 0.17	20.0 ± 5.3
ΔminCD	3.05 ± 0.7	0.34 ± 0.12	11.5 ± 4.2

SpoIIE-Ypet position was used in all cases except ΔspoIIE in which FM 4–64 signal served for septum localization. All numbers represent averages from all cells counted with standard deviation (SD). Distances are from the nearest cell poles.
