Figure 6.
Comparison of mutants corresponding to deletion of genes responsible for the formation of the rod shape or polar differentiation and wild-type strain phenotypes observed by microscopy (× 1000). The mreBCD, pbpA and rodA genes are involved in cell-shape determination in rod-shaped bacteria, whereas the minCDE genes are involved in cellular division. The cells were grown overnight in liquid media (minimal medium complemented with succinate as carbon source).
