During vegetative growth, the formation ofa Z-ring at midcell, and the subsequentassembly of the division machinery anddivision septum, leads to the formation oftwo equal daughter cells. By contrast,during sporulation, cell division isasymmetric, and unequal progeny — theforespore and the mother cell — areformed. Asymmetric cell division occursafter the transient formation of FtsZ spiralsdistributes FtsZ molecules to both poles ofthe cells, allowing the formation of an FtsZring at each pole. Only one of these formsa division or spore septum.
