Figure 4. Effects of NucS polymorphisms on mutation rates in the M. smegmatis ΔnucS surrogate model.

Figure 4

Rates of spontaneous mutations conferring Rif-R of the M. smegmatis ΔnucS complemented with wild-type nucSTBnucS/nucSTB; red) or containing each of the nine polymorphisms indicated (blue). Relative increases in mutation rates with respect to the control strain (ΔnucS/nucSTB; set to 1) are shown inside the column. Error bars represent 95% confidence intervals (n=20). Asterisks denote statistical significance (Likelihood ratio test under Luria-Delbruck model, Bonferroni corrected; ***P<0.001; **P<0.005). Mutation rate: mutations per cell per generation.
