Fig. 4From: Metabolite toxicity determines the pace of molecular evolution within microbial populationsRelative time to stationary phase for each experimental evolution condition. Data are the time to reach stationary phase for the evolved clones divided by the time to stationary phase for the ancestral clones. The horizontal bar and P-value indicates the outcome of a two-sample Wilcoxon rank-sum test. The asterisk indicates P < 0.05. The data are presented as Tukey box-plotsBack to article page
