Figure 1From: The cost of antibiotic resistance depends on evolutionary history in Escherichia coliConstruction of different genotypes and associated resistance phenotypes. (1) The wild type and three RifR genotypes evolved for approximately 200 generations in liquid LB. (2) Additional resistance elements were inserted in the form of StrR mutations on rpsL (K43N or K88R) or a SulR + StrR plasmid (RSF1010).Back to article page
