Figure S4 from Plasmid stability is enhanced by higher-frequency pulses of positive selection

<b>Gac mutations are prevalent in Hg<sup>R</sup> populations across all selective regimes.</b> The proportion of Hg<sup>R</sup> (ratio of Hg<sup>R</sup> counts over HgS counts) was plotted for each replicate population across the six selection treatments (line). Shaded region represents prevalence of Gac- phenotypes within each Hg<sup>R</sup> population. Grey bars indicate transfers where mercury was applied. Colours represent each pulsed mercury treatment.
