Bacteriophage P2 ogr and P4 delta genes act independently and are essential for P4 multiplication.

Abstract excerpt

Satellite bacteriophage P4 requires the products of the late genes of a helper phage such as P2 for lytic growth. Expression of the P2 late genes is positively regulated by the P2 ogr gene in a process requiring P2 DNA replication. Transactivation of P2 late gene expression by P4 requires the P4 delta gene product and works even in the absence of P2 DNA replication. We have made null mutants of the P2 ogr and P4...
