| Abstract: | It was shown that bacteriophage tf as well as bacteriophages phi p4/40, phi p25/42, phi p23/40 and phi p6/40, which are specific to different P. putida strains, contain the single strand breaks in their DNA. The breaks are localized in one strand of DNA molecules and are repairable with T4 DNA ligase. Bacteriophage tf has no detectable DNA homology with phi p4/40, phi p25/42, phi p23/40 and phi p6/40 bacteriophages. All the phages studied have no relation with other known Pseudomonas phages. Bacteriophages phi p4/40 and phi p25/42 share the extensive DNA homology. |
