FIG. 7.

Phylogeny of PPDK. This phylogeny groups the two oxymonads, Monocercomonoides and Streblomastix, into a single strongly supported clade. However, independent lineage-specific duplication events have occurred in both taxa. Relevant support values for these points are in bold. Sequences from putative excavate taxa are presented in bold, Monocercomonoides sequences are boxed, and anaerobic eukaryotes are denoted by an asterisk. Multiple sequences from the same organism are denoted by numbers preceded by a period (.1, .2, etc.).
