Fig. 6From: Different adaptive strategies in E. coli populations evolving under macronutrient limitation and metal ion limitationRelative fitness of mutants with yhaV Δ11 bp and ΔyhaV mutations with respect to the ancestral strain under magnesium-limiting conditions. Relative fitness of mutants was measured by competing each mutant against the wild-type strain under magnesium-limiting conditions. Each experiment was done in a duplicate. Dotted line shows a relative fitness of 1, indicating neutral effect on fitnessBack to article page
