title: [The influence of bacterial genes recB, recA, exr and polA on T4 phage DNA transfection of lysozyme spheroplasts of Escherichia coli].
abstract: The transfection efficiency of T4 phage DNA of Escherichia coli spheroplasts, carrying mutations in four genes, involved in recombination and reparation (recB, recA, exr, polA), is studied. RecB- and recA- mutations increased the phage yield during transfection, and exr- and polA- mutations decreased it. RecA- mutation is suggested to influence on spheroplasts membrane state, resulting in more efficient replication of transfecting phage DNA.
