Circular representation of the genomes of R. africae, R. conorii , and R. prowazekii based on data from GenBank entries [GenBank: NZ_AAUY01000001], [GenBank: NC_003103] and [GenBank: NC_000963], respectively. Protein coding genes common to all species are in blue; genes common to R. africae and R. conorii are in green; genes common to R. africae and R. prowazekii are in red; genes common to R. conorii and R. prowazekii are in pink and specific genes in each genomes are in yellow. Common genes are identified using best BLAST match. The region of rearrangement of the genome between R. africae and R. conorii is colored in purple; the regions of rearrangment between R. prowazekii and R. conorii are colored in orange, light green, yellow and light blue. Also represented are transfer RNAs (red arrows), ribosomal RNAs (dark arrows) and other RNAs.
