FIG. 3.

Change in nucleoid phenotype during outgrowth of germinated spores of the parent strain (BR151) (open circles) and the ripX mutant (SL7131) (filled squares). For each point, at least 200 cells were scored. The phenotypes scored are nucleoid-bilobed (NB1) and nucleoid-partitioned (NP1) (as described by Siccardi et al. [28]); they are illustrated schematically in the figure. Ch1, chromosome 1; Ch2, chromosome 2.
