Phylogenetic distribution of small-subunit rRNAs used for analysis. This dendrogram was generated from the list of organisms in our sequence alignment using the NCBI Taxonomy Browser (https://www.ncbi.nlm.nih.gov/Taxonomy/CommonTree/wwwcmt.cgi). The three principal domains of life are indicated, representing sequences from the 1345 bacteria, 519 eukarya, and 97 archaea in the CRW alignment used in this work.
