The impact of genetic background during laboratory evolution of Pseudomonas aeruginosa in a cystic fibrosis-like environment

Pseudomonas aeruginosa's adaptive trajectory: diverse origins, convergent paths

Does genetic background contribute to populations following the same or divergent adaptive trajectories? A recent study by Filipow et al. evolved multiple genetically distinct Pseudomonas aeruginosa strains to an artificial cystic fibrosis lung sputum media. The strains adapted at different rates but converged on similar phenotypes despite their initial diversity.
