+Replication-associated inversions are the dominant form of bacterial chromosome structural variation.
+
+[[!pmid 36261227 desc="“We assessed a total of 313 species that were
+represented by 10 or more complete genome sequences” “A genoform in this work
+refers to a group of collinear chromosomal sequences within a species with at
+least 80% sequence similarity and without an inversion spanning more than 50
+Kb.” “In Gammaproteobacteria, the species Haemophilus influenzae, Haemophilus
+parainfluenzae, and Mannheimia haemolytica all contained inversions that were
+predominantly located away from the replication origin. We also observed
+species that were consistently offset from symmetry in one direction such as in
+B. pertussis”"]]
In bacteria, rearrangements have been reported to generate a X-shaped pattern
in dot-plots by [[Eisen and coll (2000)|biblio/11178265]]. The authors suggest
that the patterns are generated by inversions centered on origins and termini.
+The prevalence of this phenomenon was confirmed by [[D'Iorio and Dewar,
+2022|biblio/36261227]].
