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

Gac mutations are prevalent in Hg^R populations across all selective regimes. The proportion of Hg^R (ratio of Hg^R 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^R population. Grey bars indicate transfers where mercury was applied. Colours represent each pulsed mercury treatment.
