Fig. 5. Phylogenomic analysis of the Woesearchaeotal MAG and ninety publicly available MAGs from a range of biomes show the AJ population is most closely related to Woesearchaeota from other marine water columns, including a low oxygen water mass in the Arabian Sea.

The phylogeny was constructed using an alignment of 44 single-copy gene amino acid sequences in a maximum likelihood analysis using a GAMMA model of rate heterogeneity, a BLOSUM62 protein substitution model, and 999 bootstraps.
