1Open reading frames predicted as described in the Materials and Methods;

2Average ORFs sizes shown herein were calculated using protein-coding sequences available at GeneBank: S. moniliformis (1434 protein sequences), L. buccalis (2220 protein sequences) and S. termiditis (4083 protein sequences);

3Clusters of orthologous groups as described in the Materials and Methods;

4Genes assigned to general functional prediction only (Category R) and function unknown (Category S) were not included.
