  1. aAt least 3 independent experiments were analyzed and more than 1200 bacteria were counted for each strain. Medians are indicated; (min; max) correspond respectively to the minimum and the maximum values observed for each strain.
  2. bMWU, Mann-Whitney U test for foci formation between wt and the mutants.
  3. cMedians of quantification from 5 to 15 Western blots from independent cultures are presented.
