Figure 2.
Determination of selection coefficients in the stationary state. Competitors were grown separately to T0, diluted into fresh competence medium, and mixed in a 1:1 ratio, as outlined in competition assay in the stationary phase. The fraction of wt (BD630, black circle), hyper-competent Δrok (Bs056, green triangle), and non-competent ΔcomK (Bs075, red diamond) competing against wt gfp (Bs139) cells are plotted. Full lines: best fit to replicator equation. The data were obtained from at least three independent experiments for each condition.
