Mutation frequency of the Kllsm4∆1 and the wild type CML39-11A strains. Cells were plated on minimal medium containing Canavanine sulfate after 1, 6 and 13 days of growth to determine the mutation frequency of the Can^r phenotype. Plates were incubated at 28 °C for 4 days. Results are reported as the number of Can^r mutants per 10⁶ living cells obtained from three independent experiments. *p value <0.05, **p value <0.01, ***p value <0.001
