Fig. 1. 5FC resistance is enhanced by defects in mismatch repair.

Fig. 1

a Swab assays were conducted using both the wildtype R265 strain and two independent msh2Δ::NEO mutants to test for the ability to generate resistance to 5FC. All three strains developed resistance; however, the mismatch repair mutants generated resistant isolates at a higher frequency. b A fluctuation assay was conducted to compare 5FC resistance quantitatively between wildtype R265 and two independent msh2Δ::NEO mutants. Mutation rate was normalized to the wildtype strain. Red is used to indicate wildtype strains while green indicates msh2 deletion strains. Both mutator strains showed a greater than 15-fold increase in the rate of resistance. Data shown are the mean of 10 replicates and error bars indicate 95% confidence intervals.
