| Research Abstract |
Conjugative transfer of bacterial plasmids plays an important role in rapid adaptation and evolution of host cells. However, the factors governing the host range of transfer, i.e., limited transfer to specific recipient strains within a species, remain unclear. In this study, such factors were investigated using the two plasmids encoding the traits for degradation of environmental pollutants, and the mating pair-formation in the conjugation process and a regulatory system for various metabolisms in the recipient cells were found to be involved in restricting the conjugative transfer of the plasmids.
