The linear DNA was a 4-kb fragment containing the cat gene, with flanking lac sequences, released from an infecting phage chromosome by restriction enzyme cleavage in the cell; formation of Lac(-) chloramphenicol-resistant bacterial progeny was measured. Recombinant formation was found to be reduced in ruvAB and recQ strains. In this genetic background, mutations in recF, recO, and recR had large effects on both cell viability and on recombination. In these cases, deletion of the sulA gene improved viability and strain stability, without improving recombination ability. Expression of a gene(s) from the nin region of phage lambda partially complemented both the viability and recombination defects of the recF, recO, and recR mutants and the recombination defect of ruvC but not of ruvAB or recQ mutants.en-USBacteriophage lambdaDose-Response Relationship, RadiationEscherichia coliExodeoxyribonuclease VExodeoxyribonucleases*Genes, Bacterial*Genes, ViralGenetic Complementation TestModels, Genetic*Recombination, GeneticUltraviolet RaysLife SciencesMedicine and Health SciencesJournal Articlehttps://escholarship.umassmed.edu/oapubs/657564465oapubs/657
