Deletion of rok influences the competition dynamics independent of comK. Competitors were grown separately to T2, diluted into fresh competence medium containing antibiotics as detailed in the graphs, and mixed in a 1:1 ratio. At t = 1 h, antibiotics were washed out and fresh competence medium was added. (A,B) Upper graphs: growth curves (optical density of both competitors). Lower graphs: fraction of Δrok (Bs056, black), Δrok comK (Bs142, red) cells competing against non-competent ΔcomK gfp (Bs140) cells. Each graph is a representative result of at least three independent experiments.
