Abstract


The RAD51 gene was disrupted in three different parental wild-type strains to yield three rad51 null strains with different genetic background. The rad51 mutation sensitizes yeast cells to the toxic and mutagenic effects of H2O2, suggesting that Rad51-mediated repair, similarly to that of RecA-mediated, is relevant to the repair of oxidative damage in S. cerevisiae. Moreover, pulsed-field gel electrophoresis analysis demonstrated that increased sensitivity of the rad51 mutant to H2O2 is accompanied by its decreased ability to repair double-strand breaks induced by this agent. Our results show that ScRad51 protects yeast cells from H2O2-induced DNA double-strand breakage.
