Phylogeny of dissimilatory sulfite reductases supports an early origin of sulfate respiration.
Microorganisms that use sulfate as a terminal electron acceptor for anaerobic respiration play a central role in the global sulfur cycle. Here, we report the results of comparative sequence analysisExpand

A kingdom-level phylogeny of eukaryotes based on combined protein data.
Current understanding of the higher order systematics of eukaryotes relies largely on analyses of the small ribosomal subunit RNA (SSU rRNA). Independent testing of these results is still limited. WeExpand

Nearly all of eukaryotic diversity has been classified into 6 suprakingdom-level groups (supergroups) based on molecular and morphological/cell-biological evidence; these are Opisthokonta, Amoebozoa,Expand

The tree of eukaryotes.
Recent advances in resolving the tree of eukaryotes are converging on a model composed of a few large hypothetical 'supergroups', each comprising a diversity of primarily microbial eukaryotesExpand

Multiple lateral transfers of dissimilatory sulfite reductase genes between major lineages of sulfate-reducing prokaryotes.
A large fragment of the dissimilatory sulfite reductase genes (dsrAB) was PCR amplified and fully sequenced from 30 reference strains representing all recognized lineages of sulfate-reducingExpand

The real ‘kingdoms’ of eukaryotes
We thank John Archibald, Tom Cavalier-Smith, Mark Farmer, Patrick Keeling, Herve Philippe and Susannah Porter for helpful discussions, and the Canadian Institute for Advanced Research for fellowshipExpand

Testing congruence in phylogenomic analysis.
Phylogenomic analyses of large sets of genes or proteins have the potential to revolutionize our understanding of the tree of life. However, problems arise because estimated phylogenies fromExpand

Ancient origin of the integrin-mediated adhesion and signaling machinery
The evolution of animals (metazoans) from their unicellular ancestors required the emergence of novel mechanisms for cell adhesion and cell–cell communication. One of the most important cell adhesionExpand

Archezoan protists are though to represent lineages that diverged from other eukaryotes before acquisition of the mitochondrion and other organelles. The parasite Entamoeba histolytica was originallyExpand

Resolving the order of events that occurred during the transition from prokaryotic to eukaryotic cells remains one of the greatest problems in cell evolution. One view, the Archezoa hypothesis,Expand
