Figure 6. xthA recA or xthA lexA but not xthA sulA are more sensitive to AZT than xthA single mutants.
Cultures were grown to early to mid log phase and then plated on plates containing the concentrations of AZT as indicated. Survival for wild type (●) and xthA (■) strains are shown in all panels. (A) recA (▲) and xthA recA (△)strains. (B) lexA (▼) and xthA lexA (▽)strains. (C) sulA (◆) and xthA sulA (◇) strains. Note the higher AZT concentrations in panel C.
