Supplementary Figure 7: Maximum-likelihood phylogenetic tree showing coverage of the domain Eukarya.

Maximum-likelihood phylogenetic tree showing coverage of the domain Eukarya. The tree includes all eukaryotic OTUs clustered at 97% generated in this study, their closest match in the Silva SSU NR99 v. 128 database and the reference set from the recent Tree of Life article (Hug et al., 2016). Hypervariable regions were masked with a 40% positional conservation filter, giving 1548 alignment positions, and the tree calculated using FastTree v. 2.1.3 S SE3 (Price et al., 2010). Clade names and clustering are based on the position of reference sequences. Reference sequences appear black whilst those generated in the current study are color coded based on their similarity to existing database sequences.
