Figure 8. Comparison of the segments between the wbaV and wbaU genes of Groups D1, D3, B2 and B1.

Base positions are indicated and are taken from either published or deposited sequences, as indicated in Table 1. The junctions with the neighbouring wbaV and wbaU genes are indicated by solid lines. A box cartoon to the left shows the gene clusters from Figure 4. Red arrows indicate a proposed diversification pathway of segments.
