Figure 4.

Maximum-likelihood phylogenetic analysis of (a) 16S rRNA genes and (b) derived AmoA protein sequences of isolated archaeon strain C13 with sequences from other cultivated organisms, metagenomes or cloned environmental sequences. Clade names are as described by Stieglmeier et al. (2014a) (16S rRNA) or Pester et al. (2011) (AmoA). Circles describing support represent the most conservative value from four methods used (bootstrap (ML, distance, parsimony) or posterior probabilities (Bayesian)) and the scale bar represents 0.05 changes per nucleotide or amino acid position. Accession number and environmental source are given in parentheses. If an accession number describes a genome or genomic fragment containing both a 16S rRNA and amoA gene, details are provided in the 16 rRNA tree only.
