  1. A phylogenetic tree of MutS2 subfamily from representative species showing horizontal gene transfer between bacteria and plants. Phylogenetic trees were constructed using full-length MutS2 protein sequences. The methods used in tree reconstruction and percent bootstrap values are given as in Figure 2.
