title: Temperature-sensitive mutants of bacteriophage mu.
abstract: Temperature-sensitive mutants of bacteriophage Mu, which grow at 32 C but not at 42 C, have been isolated. These mutants fall into two groups. Group 1 mutants fail to lyse host cells at nonpermissive temperatures, whereas lysis occurs normally with the group 2 mutants. All of the group 1 mutants apparently belong to the cistrons mapping to the left of gene C, whereas the group 2 mutants have lesions in various genes between D and S.
