Protist phylogeny and the high-level classification of Protozoa

  title={Protist phylogeny and the high-level classification of Protozoa},
  author={T Cavalier-smith},
  journal={European Journal of Protistology},
Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Protozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eukaryotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the ancestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont…

Multigene phylogeny and cell evolution of chromist infrakingdom Rhizaria: contrasting cell organisation of sister phyla Cercozoa and Retaria

The authors' multiprotein trees confirm that Rhizaria are sisters of infrakingdom Halvaria within chromist subkingdom Harosa (= SAR, and are consistent with holophyly of Chromista as sister of kingdom Plantae.

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

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.

Evolution of Rhizaria: new insights from phylogenomic analysis of uncultivated protists

This study provides new insights into the evolution of Rhizaria based on phylogenomic analyses of ESTs from three groups of previously under-sampled protists, and illustrates the potential of this method to elucidate the early evolution of eukaryotes by providing large amount of data for uncultivable free-living and parasitic protists.

Phylogeny and Megasystematics of Phagotrophic Heterokonts (Kingdom Chromista)

Four new biciliate bicoecean genera and five new species are described and the zooflagellate class Bicoecea (perhaps the ancestral phenotype of Bigyra) is unexpectedly diverse and a major focus of this study.

Megaphylogeny, Cell Body Plans, Adaptive Zones: Causes and Timing of Eukaryote Basal Radiations 1

Eukaryote megaphylogeny and the timing of major innovations in the light of multigene trees and the rarity of marine/freshwater evolutionary transitions are discussed.

Higher classification and phylogeny of Euglenozoa.

Deep relationships of Rhizaria revealed by phylogenomics: a farewell to Haeckel's Radiolaria.




Phylogeny of Choanozoa, Apusozoa, and Other Protozoa and Early Eukaryote Megaevolution

The taxon-rich rRNA phylogeny for eukaryotes allowing for intersite rate variation strongly supports the opisthokont clade and agrees with the view that Choanozoa are sisters of or ancestral to animals and reveals a novel nonflagellate choanozoan lineage, Ministeriida, sister either to choanoflagellates, traditionally considered animal ancestors, or to animals.

Molecular Phylogeny of Centrohelid Heliozoa, a Novel Lineage of Bikont Eukaryotes That Arose by Ciliary Loss

Phylogenetic analysis by distance and maximum likelihood methods allowing for intersite rate variation and invariable sites confirms that centrohelid heliozoa are a robust clade that does not fall within any other phyla.

Phylogeny and classification of phylum Cercozoa (Protozoa).

The protozoan phylum Cercozoa embraces numerous ancestrally biciliate zooflagellates, euglyphid and other filose testate amoebae, chlorarachnean algae, phytomyxean plant parasites, the animal-parasitic Ascetosporea, and Gromia.

Evolutionary relationships among protozoa.

The molecular phylogeny of protozoa has implications for the epidemiology and generation of human sleeping sickness epidemics, and the karyorelictids, a unique and enigmatic assemblage of marine, interstitial ciliates, are reviewed emphasizing ciliary patterns and evolution.

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.

Foraminifera and Cercozoa are related in actin phylogeny: two orphans find a home?

The union of Cercozoa and Foraminifera suggested by actin phylogeny represents a novel step in the long process of determining the broad relationships between all major eukaryotic groups.

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

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.

Principles of Protein and Lipid Targeting in Secondary Symbiogenesis: Euglenoid, Dinoflagellate, and Sporozoan Plastid Origins and the Eukaryote Family Tree 1 , 2

It is argued that dinoflagellate and sporozoan plastids are directly related and that the common ancestor of dinof lagellates and Sporozoa was photosynthetic, and a novel theory for the function of periplastid vesicles in membrane biogenesis of chlorarachneans and chromists is proposed.
