RarA-YFP characterization (A) Chronic viability assay for the RarA-YFP expressing strain. The presence of the YFP tag does not affect the viability of the strain; (B) chronic viability of ∆recX/RarA-YFP compared to wild type and ∆recX mutant. The chronic exposure to MMS produces the death of both mutant strains in the same way while wild type is still surviving; (C) Thermosensitivity assays for dnaB37 and dnaC30 replication mutants expressing RarA-YFP. The fluorescence tag does not affect the response of any of the single mutants; (D) RarA-YFP foci in B. subtilis BG1331 (rarA-yfp) cells during exponential growth after 700 ms exposure to 515 nm laser excitation. Only ~15% of the cells contain foci.
