title: Genetic studies on temperature-sensitive mutants of Bacillus subtilis bacteriophage SPP 1.
abstract: A total of 30 ts mutants of Bacillus subtilis bacteriophage SPP1 were isolated and subjected to complementation test. On the basis of this test 21 mutants were classified into 4 functional groups; the classification of the remaining 9 mutants was unclear. The frequency of recombination by mutual crossing was determined in representatives of individual groups; this made it possible to place these mutants on a linear map comprising a total length of 7.62 recombination units.
