Examples of pA/C transconjugants recovered in SO1 pSTV ::Km and DH5α. Panel A) shows the plasmid profiles of four different transconjugants in SO1 marked within dotted rectangles. The donor YU39 pA/C and the recipient SO1pSTV::Km strains are in the first and last lanes, respectively. Within each dotted rectangle, in the first lane are the SO1 transconjugants; in the second and third lanes the DH5α transformants for the pA/C and pSTV of each transconjugant are shown. Panel B) displays examples of PstI restriction profiles of pA/C transconjugants of SO1 and DH5α compared with wild-type YU39 pA/C (DH5α-pA/C).
