    Notes: Development of the Escherichia coli cell division site was studied in wild-type cells and in non-septate filaments of ftsZ null and ftsZTs mutant cells. Localized regions of plasmolysis were used as markers for the positions of annular structures that are thought to be related to the periseptal annuli that flank the ingrowing septum during cytokinesis. The results show that these structures are localized at potential division sites in non-septate filaments of FtsZ- cells, contrary to previous reports. The positions of the structures along the long axis of the cells in both wild-type cells and FtsZ- filaments were unaffected by the presence of plasmolysis bays at the cell poles. These results do not agree with a previous suggestion that the apparent association of plasmolysis bays with future division sites was artefactual. They support the view that division sites begin to differentiate before the initiation of septal ingrowth and that plasmolysis bays and the annular attachments that define them, mark the locations of these early events in the division process.

    Notes: Early changes at cell-division sites were studied in non-septate filaments induced by growth of ftsATs mutant cells under non-permissive conditions. The positions of localized regions of plasmolysis were used as markers for the locations of partial and complete annular structures that are thought to be precursors of the periseptal annuli that flank the septum during cytokinesis. The results confirmed that these structures were localized at potential division sites and suggested a model in which older division sites play a role in the generation of new sites for future use, with each older site being used only once for this purpose. The results also suggest that the details of division-site development can profitably be studied in cells in which early events in the differentiation process are uncoupled from the septation event.
