Many of the protists thought to represent the deepest branches on the eukaryotic tree are assigned to a loose assemblage called the "excavates." This includes the mitochondrion-lacking diplomonads and parabasalids (e.g., Giardia and Trichomonas) and the jakobids (e.g., Reclinomonas). We report the first multigene phylogenetic analyses to include a comprehensive sampling of excavate groups (six nuclear-encoded protein-coding genes, nine of the 10 recognized excavate groups). Excavates coalesce…

Phylogenomic analyses support the monophyly of Excavata and resolve relationships among eukaryotic “supergroups”

TLDR
A phylogenomic analysis of a dataset of 143 proteins and 48 taxa indicates that Excavata forms a monophyletic suprakingdom-level group that is one of the 3 primary divisions within eukaryotes, along with unikonts and a megagroup of Archaeplastida, Rhizaria, and the chromalveolate lineages.

Taxon-rich phylogenomic analyses resolve the eukaryotic tree of life and reveal the power of subsampling by sites.

TLDR
A taxon-rich phylogenomic analysis including 232 eukaryotes selected to maximize taxonomic diversity and up to 1554 genes chosen as vertically inherited based on their broad distribution among eukarian lineages finds strong support for five major clades, including Amoebozoa, Excavata, Opisthokonta, Archaeplastida, and SAR.

Protist Evolution and Phylogeny

TLDR
A new higher level classification of eukaryotes combining the results of microscopic and various ‘omics’ studies has been proposed, and important part of protist diversity has been uncovered by environmental DNA study.

Monophyly of Rhizaria and multigene phylogeny of unicellular bikonts.

TLDR
The first large-scale analysis of eukaryote phylogeny including data for 2 rhizarian species, the foraminiferan Reticulomyxa filosa and the chlorarachniophyte Bigelowiella natans, confirms the monophyly of Rhizaria (Foraminifera + Cercozoa), with very high bootstrap supports in all analyses.

Combined morphological and phylogenomic re-examination of malawimonads, a critical taxon for inferring the evolutionary history of eukaryotes

TLDR
The ‘malawimonad+metamonad signal’ in morphological and molecular data argues against a strict Metamonada+Discoba clade, and should not be assumed when inferring deep-level evolutionary history in eukaryotes.

Molecular phylogeny of diplomonads and enteromonads based on SSU rRNA, alpha-tubulin and HSP90 genes: Implications for the evolutionary history of the double karyomastigont of diplomonads

TLDR
It is suggested that all higher taxa intended to unite multiple enteromonad genera be abandoned, that Trimitus and Enteromonas be considered as part of Hexamitinae, and that the term 'enteromonads' be used in a strictly utilitarian sense.

Evolutionary position of breviate amoebae and the primary eukaryote divergence

TLDR
It is shown that phylogenomics of phylogenetically ‘nomadic’ species can elucidate key questions in eukaryote evolution and establish Breviata as a deep-branching unikont, and remnants of mitochondria have been detected in all putatively deep-BRanching amitochondriate organisms.

Evolutionary relationships of apusomonads inferred from taxon-rich analyses of 6 nuclear encoded genes.

TLDR
The data suggest that unikonts (=Opisthokonta and Amoebozoa) are not strictly monophyletic and are descended from biflagellate ancestors, rather than the current model that eukaryotes are divided into primary "unikent" and "bikont" clades.

Analysis of Rare Genomic Changes Does Not Support the Unikont–Bikont Phylogeny and Suggests Cyanobacterial Symbiosis as the Point of Primary Radiation of Eukaryotes

TLDR
The RGC analysis suggests that excavates are significantly more likely to cluster with the unikont–Chromalveolata assemblage than with the Plantae, and the first split in eukaryotic evolution might lie between photosynthetic and nonphotosynthetic forms and so could have been triggered by the endosymbiosis between an ancestral unicellular eUKaryote and a cyanobacterium that gave rise to the chloroplast.

Inference of the phylogenetic position of oxymonads based on nine genes: support for metamonada and excavata.

TLDR
It is demonstrated that the genes are in conflict regarding the position of oxymonads, and a well-supported group of Metamonada that branched weakly with euglenozoans is recovered, providing conditional support for the existence of Excavata.

Retortamonad flagellates are closely related to diplomonads--implications for the history of mitochondrial function in eukaryote evolution.

TLDR
The robust phylogenetic association between diplomonad and retortamonads suggests that they share an amitochondriate ancestor, and strong evidence indicates that diplomonads have secondarily lost their mitochondria.

TLDR
An overview of the controversial proposal for the major eukaryote taxon "Excavata" is presented, with phylogenetic diagnoses for Excavata and for two novel taxon names, Fornicata (Carpediemonas, retortamonads, diplomonads) and Preaxostyla (Trimastix, oxymonads).

Oxymonads are closely related to the excavate taxon Trimastix.

TLDR
Rigorous phylogenetic analyses indicate that oxymonads and Trimastix are sister taxa and are not clearly related to any currently established eukaryotic lineages, a surprising result that has important implications for the understanding of cellular evolution and high-level eUKaryotic phylogeny.

The analysis of 100 genes supports the grouping of three highly divergent amoebae: Dictyostelium, Entamoeba, and Mastigamoeba

The phylogenetic relationships of amoebae are poorly resolved. To address this difficult question, we have sequenced 1,280 expressed sequence tags from Mastigamoeba balamuthi and assembled a large

Evolutionary relationships among "jakobid" flagellates as indicated by alpha- and beta-tubulin phylogenies.

TLDR
Tubulin gene phylogenies were in general agreement with mitochondrial gene phylogenIES and ultrastructural data in indicating that the "jakobids" may be polyphyletic.

The chaperonin genes of jakobid and jakobid-like flagellates: implications for eukaryotic evolution.

TLDR
The Reclinomonas and Malawimonas sequences presented here are among the first nuclear protein-coding genes to be described from these organisms, and unlike other putative early diverging protist lineages, a high density of spliceosomal introns was found in the jakobid and malawimonad CCTs-similar to that observed in vertebrate protein- coding genes.

Phylogenomics of eukaryotes: impact of missing data on large alignments.

TLDR
This large data set provides a reliable phylogenetic framework for studying eukaryotic and animal evolution and will be easily extendable when large amounts of sequence information become available from a broader taxonomic range.

TLDR
Investigation of the nuclear genomes of entamoebae, Microsporidia, parabasalids, and diplomonads suggests that these organisms likely descend from mitochondrion‐bearing ancestors, and most evidence suggests that the mitochondrial endosymbiosis took place prior to the divergence of all extant eukaryotes.
