The 100-kb B6 blocks with extremely high sequence similarity to the MSM and JF1 strains. (A) The number of 100-kb B6 blocks with extremely high sequence similarity to the MSM and JF1 strains. The B6 blocks were compared to their counterparts in the MSM and JF1 strains for each 0.001% block from 99.990% to 100% similarity. (B) The chromosomal locations of the 100-kb B6 blocks with sequence similarity >99.998% to the MSM and JF1 chromosomes. Horizontal black boxes depict the regions with >99.85% sequence similarity to the MSM strain. Gray boxes indicate gaps in the B6 reference sequence.
