From: Dynamics of cheater invasion in a cooperating population of Pseudomonas aeruginosa
Co-cultures of PAO1 PsdR mutant (squares) and PsdR-LasR double mutant (circles) in 1% casein broth. Initial frequency of the LasR mutant was 1% (filled symbols) or 10% (open symbols). (a) Cell density was measured as CFU (see Methods). (b) Rate of change in cell density, calculated from the data in panel a (see Methods). (c,d) PsdR-LasR mutant frequency, calculated from data in panel a. All data are means of three replicates and the error bars represent the SEM of the data.
