Fig. 6

Dose dependence of mutagenesis induced by AG. Azidoglycerol (AG) has been applied at the doses indicated on the X-axis to the classical Ames tester strains and their PolV-deficient derivatives (left panel) or to the new Ames tester strains overexpressing the activated PolRI* and SamA’B polymerase subunits from the uninduced (middle panel) or induced (right panel) lac promoter. The induced His+ revertant counts displayed on the Y-axis were calculated by subtracting the average spontaneous revertant number for a given strain from the total number of revertants per plate values. The strains used are shown in the graph legend and described in Table 1 in detail
