Note: Bacteria are numbered as in Figure 6. In the dnaE1|polV group, there are 10 outliers; however, nine belong to the high-GC category and only one to the high-AT category. In the dnaE3|polV group, three belong to the high-GC and three to the high AT-category. "+" and "-"represent the presence and absence of mutator genes, respectively.
