Abstract

Morphological mutants of the c type of the bacteriophage G101 (Pseudomonas aeruginosa) were isolated after mutagenesis with hydroxylamine. Complementation analysis of 27c mutants showed that thec region is formed by at least two genes. Two types ofc mutants were obtained. One of them (cI26) behaves analogously to a mutant in the gene controlling the synthesis of the repressor of phage λ. The second type of thec mutants (cII1, cII18) specifies a gene having probably an auxiliary function in the “c” region. According to the low frequency of recombination between the genes cI26 and cII18 (1.37 recombination units), these genes responsible for lysogenization are localized in a short region of the chromosome.
