Phylogenetic comparison of the HUS⁺Geobacillus strains on the basis of RecN and XynDCEFG-XylAB. A neighbour-joining tree was constructed on the basis of the RecN amino acid sequences of the HUS⁺Geobacillus strains as well as sixteen representatives of related genera in which orthologs of XynDCEFG-XylAB are present. Similarly a neighbour-joining tree was constructed based on alignment of the concatenated XynDCEFG-XylAB amino acid sequences. Desmospora sp. 8437 was used as outgroup and bootstrap values are shown (n = 1,000). The branches in red and in green, represent the phylogenetic positions of Geobacillus sp. C56-T2 and G. caldoxylolyticus CIC9, respectively, in both trees.
