Combining live fluorescence imaging with in situ cryoelectron tomography sheds light on the septation process in <i>Deinococcus radiodurans</i>.

ABSTRACT: Cell division is a fundamental biological process that allows a single mother cell to produce two daughter cells. In walled bacteria, different modes of cell division have been reported that are notably associated with distinctive cell shapes. In all cases, division involves a step of septation, corresponding to the growth of a new dividing cell wall, followed by splitting of the two daughter cells. The radiation-resistant Deinococcus radiodurans is a spherical bacterium protected by a thick and unusual cell envelope. It has been reported to divide using a distinctive mode of septation in which two septa originating from opposite sides of the cell progress with a flat leading edge until meeting and fusing at mid-cell. In the present study, we have combined conventional and superreso
