Bacteriophage D3112 forms two types of PA01 (D3112) lysogens: those that partially, or completely, limit the growth of the related heteroimmune phage B39. DNA/DNA hybridization has shown that the lysogens of the first type always contain one copy of prophage D3112 (monolysogens), and the lysogens of the second type contain two or more copies of prophage D3112. Limitation of the growth of phage B39 on PA01 (D3112) lysogens is associated with the functioning of the locus of prophage D3112, designated as cip (control of interaction of phages). Using deletion derivatives of plasmid RP4::D3112, the cip locus was mapped at an interval of 1.3-2.45 kb of the D3112 genome. The expression of the cip locus occurs only if the D3112 genome is at the prophage state. The function of the Cip prophage of D3112 exerts an influence on early stages of development of phage B39, decreasing the efficiency of the integration and transposition processes of phage B39.
