Genetic adaptations to the antibiotics amikacin (AMK), piperacillin (PIP), and tetracycline (TET). The color represents the number of strains in percent that harbor a mutation, identified in at least two independent lineages. Almost all mutations identified in the gradient approach are also present in at least one of the increment strains. PIP and TET evolved lineages display similar genotypes with mutations predominantly affecting the mar phenotype.
