The sums of genetic changes acquired after 700 generations of evolution by a nitrite (NO2) producing clones (one clone per culture) evolved at pH 7.5 (weak nitrite toxicity, weak interdependence) or pH 6.5 (strong nitrite toxicity, strong interdependence), or b nitrite reducing clones (one clone per culture) evolved at pH 7.5 (weak nitrite toxicity, weak interdependence) or pH 6.5 (strong nitrite toxicity, strong interdependence). The horizontal bars and P-values indicate the outcomes from two-sample Wilcoxon rank-sum tests. The star indicates a P-value 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. The numbers of genetic changes acquired by the nitrite reducing clones are significantly greater after evolution at pH 6.5 (strong nitrite toxicity, strong interdependence) than at pH 7.5 (weak nitrite toxicity, weak interdependence)
