Figure 8

The location of all SNDs in a 5 kb region. In clusters demarcated by colored lines, note the corresponding absence of two more common types of SNDs. Three diamonds in lighter shades of blue, green, and red are compatible tri-partitions (see Additional data file 1). Colored lines demarcate regions where the absence of lineage-specific SNDs is offset by an increase in the corresponding recombinant pattern (for example, in yiaA, no K-12 or S. flexneri only SNDs).
