Extensive level of genome rearrangement between closely related Spiroplasma spp. The color blocks represent regions of homologous backbone sequences without rearrangement among the genomes compared. The vertical red bars indicate the boundaries of individual contigs. The average nucleotide sequence identities were calculated based on single-copy genes that were conserved among the three genomes compared in each group. (A) Comparison among Spiroplasma melliferum IPMB4A, S. melliferum KC3, and S. citri GII3-3X. (B) Comparison among Mycoplasma hyopneumoniae strains 7448, J, and 232. (C) Comparison among Bacillus anthracis str. Ames, B. cereus ATCC 10987, and B. thuringiensis serovar konkukian str. 97-27.
