^aEach reliability score is the number of nodes with bootstrap values greater than or equal to 80 divided by total number of nodes of phylogenetic trees reconstructed using the maximum parsimony, maximum likelihood, minimum evolution, and neighbor joining methods grouped into subsets (groups of homogenous means) with a P value of 0.05 for confidence level using the Ryan-Einot-Gabriel-Welsch F test. The genes used in the concatemers are as follows: 16S rRNA gene, ftsZ, gapA, gyrB, recA, or rpoA in 1-gene concatemers, recA and rpoA in 2-gene concatemers, recA, rpoA, and gapA in 3-gene concatemers, 16S rRNA gene, recA, rpoA, and gapA in 4-gene concatemers, 16S rRNA gene, recA, rpoA, gapA, and gyrB in 5-gene concatemers, and 16S rRNA gene, recA, rpoA, gapA, gyrB, and ftsZ in 6-gene concatemers.
