Compatibility properties of P1 and PhiAMP prophages.
Although phages P1 and PhiAmp are heteroimmune (Chesney and Scott, 1975 and Yarmolinsky, unpublished), their plasmid prophages are incompatible. Thus, the immunity and compatibility systems are two distinct regulators of phage replication. The two prophages, and plasmid P15B (Ikeda, Inzuka and Tomizawa, 1970) constitute a new compatibility group, designated Y.
