X-7088 Abstract A segment (hft) of bacteriophage FP43 DNA cloned into plasmids pIJ702 or pMT660 mediates high frequency transduction of these plasmids by FP43 in Streptomyces griseofuscus. Lysates of FP43 prepared on S. griseofuscus containing the plasmids with the hft segment also transduce many other streptomyces species, including several species that restrict plaque-formation by FP43 and at least two species that produce restric- tion endonucleases that cut the plasmid DNA. Trans- duction efficiencies in different species are influenced by the addition of anti-FP43 antiserum to the trans- duction plates, the temperature for cell growth before transduction, the multiplicity of infection, and the host on which the transducing lysate is prepared. Transducing lysates prepared on S. griseofuscus are also able to mediate plasmid transfer to species of Streptoverticillium, Chainia, and Saccharopolyspora.
