FIG 2 .

Genes (n = 14) containing mutations after selection under conditions of constant or fluctuating ciprofloxacin treatment. The black squares in the large matrix denote genes that had mutational changes, and the numbers within the boxes represent the codon number where the change occurred. Differently colored numbers represent different amino acid changes. The colored squares in the smaller matrices denote PseudoCap (51) functions of the genes. The asterisk indicates that a modified PseudoCap function was used, as known fluoroquinolone resistance-conferring genes were included within this functional category. LPS, lipopolysaccharide.
