Phylogenetic tree of deduced amino acid sequences of hydA in representative OTUs containing more than five clones, and the proportion of clones in subclusters to libraries. Clones with bold names indicate amino acid sequences derived from hydA transcripts obtained in this study. The numbers at the branches indicate bootstrap values (≥50%) with 1,000 replicates. Clustering (shown in grey squares) is based on phylogenetic relationships among the sequences. The sizes of circles and numbers on the right column show the relative abundance and percentages (≥10%) of clones belonging to each cluster among all clones in each library.
