An integrative vector system has been developed from the site-specific recombination elements of temperate phage 16-3. The system can be used for highly efficient stable introduction of genetic material into the chromosome of the symbiotic nitrogen-fixing organism, Rhizobium meliloti 41 (Rm41) at the attB site. Vectors carrying the phage-bome attachment site were constructed, and helper phages providing the site-specific recombination functions in trans were isolated. Other possible applications of the system are discussed.
