Genetic mapping of the region c of the bacteriophage G101 (Pseudomonas aeruginosa).
Morphological mutants of the c type of the bacteriophage G101 (Pseudomonas aeruginosa) were isolated after mutagenesis with hydroxylamine. Complementation analysis of 27 c mutants showed that the c region is formed by at least two genes. Two types of c mutants were obtained. One of them (cI26) behaves analogously to a mutant in the gene controlling the synthesis of the repressor of phage lambda. The second type of the c 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 c II18 (1.37 recombination units), these genes responsible for lysogenization are localized in a short region of the chromosome.
