This tracks examples of bacteria and archaea syntenic dotplots which do not show the classical x-alignment pattern of inversions. One possible methodological reason for these non-x-alignments is mis-assembly.

Local region of syntenic instability

These are interesting. Lots of inversions at the same local sub-regions, but not around a single point in the genome. Perhaps there is some factor contributing to a local region of syntenic instability?
