All of the insertion sequences (ISs) except for IS663 and a group II intron identified in the alkaliphilic Bacillus halodurans C-125 genome were also detected in nine other strains of the same species by PCR and Southern blot analysis. The transposase of IS 653 identified in the genomes of the 10 strains of B. halodurans was found to have become the most diversified of all ISs identified in the genomes of 10 strains. A new IS element designated IS661 belonging to the IS1380 family with inverted repeats (IRs) 17 bp in length was present within IS658 identified in the genome of B. halodurans A59. In addition, a new transposon designated Tn3271bh was identified within the IS642 element in the A59 genome, which is similar to a transposon identified in thermophilic Geobacillus stearothermophilus T-6. The new transposon, Tn3271bh, generated an 8-bp duplication of the target site sequence and carries a 21-bp IR. On the other hand, all kinds of ISs except for IS643 and IS658 were distributed in the genome of obligately alkaliphilic Bacillus alcalophilus. Three ISs (IS652, IS653, and IS660) and a group II intron (Bh.Int) were widely dispersed in other Bacillus species without a correlation with the phylogenetic placement based on 16S rDNA sequences.
