Comparison of Mmc 95010 and Mmc GM12 genome organisation in relation to mobile elements. The colinear blocks identified by Mauve software in the closely related Mmc 95010 and Mmc GM12 genomes are shown. The various mobile elements where then positioned on the graph. IS1296 copies are represented by dark blue lozenges, ISMmy1 by red triangles, ISMmy2 by green circles, ISMmy3 by vertical blue lines and ICEs by red horizontal rectangles. Eight IS1296 copies are found in each genome but only two map at the same site (copies 6 and 7 in Mmc 95010). In addition, two copies of IS1296 are positioned on either side of an inverted DNA fragment: duplication and transposition of this IS may have been responsible for this inversion. Similarly, the duplication of the ICE in the Mmc 95010 genome may have caused the inversion of a large DNA fragment.
