FIG. 7.

Sequences of the junction points between pMABcatRAB and the S. suis genome. The sequences of pMABcatRAB and the corresponding S. suis genomic sequences are shown in the upper part of each panel. The sequence of the mutant is shown in the lower part of each panel. Stretches of sequence identity that are presumed to be the junction points are boxed with thick lines. Other positions with nucleotide identity are boxed with thin lines. Hooked arrows intercrossing the junction points of the mutants indicate possible positions of crossover, showing the recombination flow starting from the chromosome and shifting to the plasmid (left) and from the plasmid to the chromosome (right). Nucleotide mismatches found in the junction regions of Int1 and Int6 are indicated by upward-pointing arrows.
