Agrobacterium tumefaciens divisome proteins regulate the transition from polar growth to cell division

What is it about?

In Agrobacterium tumefaciens unipolar elongation is followed by growth at mid-cell, enabling cell division. Remarkably, the absence of FtsZAT causes growth poles to accumulate due to tip splitting events because peptidoglycan synthesis is not redirected from the growth pole to mid-cell. In contrast, the absence of downstream division proteins, FtsA or FtsW, causes ectopic growth poles to emerge from mid-cell, indicating that these proteins are not necessary for the redirection of growth to mid-cell.
