Enhancement of mutagenesis in gamma ray exposed Escherichia coli by plasmids of different incompatibility groups.
We have analyzed the correlation between plasmid incompatibility group and enhanced mutagenesis in gamma ray exposed Escherichia coli WP2. The data reported indicate that plasmids of different incompatibility groups are involved in DNA repair mechanisms and suggest that the damage of the DNA produced by gamma rays or other physical agents and by chemical mutagens stimulates a common mechanism of bacterial DNA repair.
