Fig. 2From: Different adaptive strategies in E. coli populations evolving under macronutrient limitation and metal ion limitationa) Potential targets of selection under nitrogen limiting conditions: Trajectories for mutations that reach frequencies of 35% or more for all the populations evolving under nitrogen limiting conditions. Different populations are shown as different shapes. Populations were sequenced at two time points (generations 168 and 400). Genes showing mutations among replicates are written in bold. Different mutations are shown as different types of lines. b) Potential targets of selection under magnesium limiting conditions: Trajectories for mutations that reach frequencies of 35% or more for all the populations evolving under magnesium limiting conditions. Different populations are shown as different shapes. Populations were sequenced at two time points (generations 168 and 400). Genes showing mutations among replicates are written in bold.
