The numbers of genetic changes acquired by clones (one clone per culture) after 700 generations of evolution at pH 6.5 (strong nitrite [NO2−] toxicity, strong interdependence). The horizontal bars and P-values indicate the outcomes from two-sample Wilcoxon rank-sum tests. The stars indicate P-values less than 0.05. Data are presented as Tukey box-plots. The numbers of genetic changes include synonymous and non-synonymous point mutations, insertions, deletions, and multiplications. Panels are for a data excluding the single completely denitrifying clone with a genetic change in uvrA, and b data including the single completely denitrifying clone with a genetic change in uvrA (indicated by the red arrow). The completely denitrifying clones generally acquired significantly more genetic changes than the nitrite producing or reducing clones
