A general, genetic technique for in vivo cloning of bacterial genes is presented. We previously introduced the Mu phage into various genera of bacteria including Klebsiella aerogenes with RP4:: Mu. Using these strains carrying RP4:: Mu cts and thermo-inducible Mu prophage in the chromosome, we cloned in vivo the arylsulfatase (ats) and tyramine oxidase (tyn) genes by partial thermo-induction. The donor strains carrying the recombinant plasmids were conjugated with K. aerogenes rec strains, which were isolated as UV-sensitive mutants. The resultant recombinant plasmids, pATl and pAT2, were purified and used for the transformation of mutant strains deficient in the ats and tyn genes. The ats-tyn genes seemed to be transposed into the RP4::Mu cts plasmid together with other chromosomal DNA fragments. This in vivo cloning method is applicable to a wide variety of gram-negative bacteria.
