The Evolution of Two-Component Systems in Bacteria Reveals Different Strategies for Niche Adaptation
Figure 7
Extent of Domain Shuffling in Different Classes of HPKs
The fraction of HPKs with identical upstream domains to either their inferred HGT partners (red bars), or to their closest paralog (blue bars) in the case of LSE. Only genes that are not believed to have undergone duplication within a lineage are used in the HGT group. B. japonicum, which has a significant number of genes classified as HGT and LSE, is shown twice.
