Abstract:
:The TOL plasmid originally isolated in Pseudomonas putida (arvilla) mt-2 was transmissible to strains of the fluorescens group of Pseudomonas, i.e., P. putida, P. fluorescens, and P. aeruginosa, except for a strain of P. aeruginosa, strain PAO. The same strain, however, could accept the plasmid when its restriction and modification abilities were lost by mutations or by growing at high temperature. In addition, the transmissibility of the TOL plasmid from strain PAO to P. putida was low when the plasmid was modified by the donor. By using P. aeruginosa PAO carrying the TOL plasmid, the stability and genetic expression of the plasmid as well as its effect on the host cell growth were examined. Thus the self-maintenance of the plasmid was found to be thermosensitive. Furthermore, the TOL plasmid inhibited the growth of strain PAO at high temperature, accompanied by the formation of some filamentous cells. These thermosensitive properties of the TOL plasmid were host dependent and not exhibited in another strain of P. aeruginosa.
