A pyocinogenic factor responsible for the production of pyocin R2, a bacteriocin which resembles a phage tail, was suggested to be located on the chromosome of Pseudomonas aeruginosa. By conjugation experiments employing pyocin-less strains as recipients, the pyocin locus was found to be linked to a tryptophan marker. A pyocin-less character could also be transmitted from a male to a pyocin-positive female strain. A tentative map of the Pseudomonas chromosome including pyocin R2 as well as other markers was presented.
