The cidA/cidB operon displays polymorphism within and between different wPip strains, whereas no polymorphism is observed for the cinA/cinB operon. Mapping onto the reference genome wPip_Pel of the Illumina reads from the Tunis line infected with wPipI, and from the Harash and Istanbul lines infected with wPipIV. Colored residues are different from those in the reference wPip_Pel sequence. The pattern above the dotted lines represents the number of Illumina reads that have mapped for each position. The red box on the wPip_Pel reference genome allows the IGV user to locate the zone that is visualized with more details on the bottom panels. a Mapping of the cidA/cidB operon reads onto the wPip_Pel reference genome. Polymorphism between wPip groups was detected (differences between Harash and Istanbul infected with wPipIV, Tunis, and wPip_Pel infected with wPipI). Polymorphism was also detected within Wolbachia groups (variations observed between Tunis and wPip_Pel or between Harash and Istanbul). The operon was also found to be polymorphic within the same isofemale line of C. pipiens. b Mapping of the cinA/cinB operon reads onto the wPip_Pel reference genome. No polymorphism was detected between reads from the three isofemale lines and the reference line
