title: [Reversion induction in phage T4 mutants in Escherichia coli strains with defective RNA polymerase].
abstract: The reversion induction in mutants of phage T4 under the effect of base analogues in RNA-polymerase Escherichia coli mutants is studied. In double mutant E. coli rif-r stl-r strain  phage T4 mutates several times more frequently than in the parental strain of E. coli RFS-522, containing an intact enzyme.
