IS30 'jumping' in the genome of B. longum DJO10A. (A) Genome positioning of the IS30 elements in the genome of B. longum DJO10A and the laboratory adapted strain DJO10A-JH1. The gray arrows indicate the five elements identified by direct sequencing of DJO10A genomic DNA. The white arrows indicate the location of elements that were detected in some sequencing clones prepared from DJO10A genomic DNA. The asterisk under A6 indicates this element was missing from some sequencing clones of DJO10A DNA. (B) Nru I digested genomic DNA from DJO10A shown in the left gel and its Southern hybridization (right gel) using probes specific for four different IS element families. (1) refers to DJO10A and (2) refers to DJO10A-JH1. Arrows indicate bands in DJO10A corresponding to specific IS30 elements as illustrated in (A).
