Change in frequency of phoQ L467P mutant in competition with a wild type strain and b phoQ L467PΔyhaV double mutant under magnesium limiting conditions: Natural logs of the ratio between the population size of the competing strains is shown. Each experiment was performed as a duplicate and shows in both cases stabilization of the phoQ L467P mutant with the a wild type strain, even when the starting ratio of the strains are different (1:2 and 1:20) and b phoQ L467P ΔyhaV double mutant in a ratio of ~ 7:1 i.e. ln(2)
