Septation and chromosome segregation during sporulation in Bacillus subtilis.
The early stages of sporulation in Bacillus subtilis incorporate a modified, highly asymmetric cell division. It is now clear that most, if not all, of the components of the vegetative division machinery are used also for asymmetric division. However, the machinery for chromosome segregation may differ significantly between vegetative growth and sporulation. Several interesting checkpoint mechanisms couple cell cycle events to gene expression early in sporulation. This review summarises important advances in the understanding of chromosome segregation and cell division at the onset of sporulation in B.subtilis in the past three years.
