| Abstract: | The plasmid pIP231 exhibits stronger incompatibility with both plasmid prophages P1 and P7 than P1 and P7 exhibit with each other. DNA-DNA hybridization experiments showed that pIP231 is strongly homologous with both P1 and P7 in the central region of the prophage genomes which contains genes determining replication, incompatibility, and maintenance functions. In addition, a region on the left of P7 which contains Tn902 showed some homology with pIP231, as did the region of P1 carrying IS1. |
