Quantification of cidA-cidB operon in different wPip genomes

graphic file with name 41467_2017_2749_Figb_HTML.gif

The number of copies of the cidA and cidB genes was estimated by real-time q-PCR, relative to the reference gene wsp known to be present as a single copy per genome. The number of copies was determined by calculating the ratio between cidA (or cidB) signals and wsp signals on four individuals per line. ± means s.d.The cidA to cidB ratio was always close to one. The numbers of cidA and cidB copies present per Wolbachia genome were therefore similar, as expected for an operon.
