Wild-type and mutant GCR rates.

aFolds were calculated with respect to each assay's wild type rate; absolute rates for certain strains were taken from previous publications as indicated, but folds were calculated to the wild type rates measured in this study.bClasses were determined based on significance of the mutations' 95% confidence intervals for their median GCR rates. Mutations caused: I) a significant increase, II) no significant change, or III) a significant decrease in the +Ty912 GCR rate and A) a significant increase or B) no significant change of the −Ty GCR rate.cSee [68].dSee [8].eSee [69].fSee [70].gSee [71].
