Rod-shaped bacteria usually grow in length and place their FtsZ ring and division site at midcell, perpendicular to their long axis [1,2]. Here, we provide morphometric and immunocytochemical evidence that a nematode-associated gammaproteobacterium [3,4] grows in width, sets a constricting FtsZ ring parallel to its long axis, and divides longitudinally by default. Remarkably, the newly described FtsZ ring appears to be not only 90 degrees shifted with respect to model rods, but also elliptical and discontinuous. This reveals an unexpected versatility of the gammaproteobacterial cytokinetic machinery.
