Alignment of the chromosomes of strains TX07-7308 (top) and ATCC 25017 (bottom) using MAUVE 2. Identically colored boxes, known as locally collinear blocks (LCBs), depict homologous regions in the two chromosomes. The edges of LCBs indicate chromosome rearrangements due to recombination, insertions, and/or inversions. Sequences of strain ATCC 25017 inverted in relation to those of strain TX07-7308 are shown as blocks below the horizontal line. The vertical lines connecting the LCBs point to regions of homology among the two chromosomes. Numbers above the maps indicate nucleotide positions within the respective chromosomes.
