Abstract In an attempt to reconstruct early alveolate evolution, we have examined the phylogenetic position of colpodellids by analyzing small subunit rDNA sequences from Colpodella pontica Myl’nikov 2000 and Colpodella sp. (American Type Culture Collection 50594). All phylogenetic analyses grouped the colpodellid sequences together with strong support and placed them strongly within the Alveolata. Most analyses showed colpodellids as the sister group to an apicomplexan clade, albeit with weak… 

Molecular Phylogeny and Surface Morphology of Colpodella edax (Alveolata): Insights into the Phagotrophic Ancestry of Apicomplexans

P phylogenetic analyses of small subunit rRNA gene sequences from Colpodella edax and three unidentified eukaryotes published from molecular phylogenetic surveys of anoxic environments showed C. edax was the sister group to (eu)apicomplexans and dinoflagellates.


This work addressed the earliest stages of alveolate evolution by sequencing heat shock protein 90 genes from several ciliates, apicomplexans, and dinoflagellates, including key species thought to represent early diverging lineages: Oxyrrhis marina, Perkinsus marinus, Cryptosporidium parvum, and the eugregarine Monocystis agilis.

Alveolate Phylogeny Inferred using Concatenated Ribosomal Proteins

Constant concatenated protein‐coding genes from expressed sequence tags or genomic data are used to construct phylogenies including “typical” dinophycean dinoflagellates, a parasitic syndinian dinof lagellate, Amoebophrya sp.

Molecular Phylogeny of Parvilucifera prorocentri (Alveolata, Myzozoa): Insights into Perkinsid Character Evolution

Molecular phylogenetic analyses demonstrated that P. prorocentri branched as a sister lineage to a divergent clade consisting of Parvilucifera infectans and Parviluca sinerae, and built a more comprehensive framework for understanding the earliest stages in the evolution of myzozoans.


Eugregarines formed a monophyletic group with the neogregarine Ophryocystis, suggesting that trophozoites with elaborate cortex folds and gliding motility evolved only once.

Description of Colponema vietnamica sp.n. and Acavomonas peruviana n. gen. n. sp., Two New Alveolate Phyla (Colponemidia nom. nov. and Acavomonidia nom. nov.) and Their Contributions to Reconstructing the Ancestral State of Alveolates and Eukaryotes

The morphological data presented here suggests that colponemids are central to the authors' understanding of early alveolate evolution, and suggest they also retain features of the common ancestor of all eukaryotes.



Molecular Determination of the Phylogenetic Position of a Species in the Genus Colpodella (Alveolata)

These findings, and the nearly identical ultrastructural characteristics of Colpodella, Perkinsus, and Parvilucifera species, suggest that this morphology is the ancestral condition for all of Alveolata.

Phylogeny of gregarines (Apicomplexa) as inferred from small-subunit rDNA and beta-tubulin.

The congruence of SSU rDNA and beta-tubulin trees with one another and with morphological data does suggest that further sampling of molecular data will eventually put gregarine diversity into a phylogenetic context.

Re-examining Alveolate Evolution Using Multiple Protein Molecular Phylogenies

Six genes from the non-photosynthetic dinoflagellate, Crypthecodinium cohnii: actin, beta-tubulin, hSp70, BiP, hsp90, and mitochondrial hsp10 were found to be useful for intra-alveolate phylogeny, and trees were inferred from these genes individually and in combination.

Multiple protein phylogenies show that Oxyrrhis marina and Perkinsus marinus are early branches of the dinoflagellate lineage.

Together, these two organisms can be instrumental in reconstructing the early evolution of dinoflagellates and apicomplexans by helping to reveal aspects of the ancestors of both groups.

Phylogeny of Ultra-Rapidly Evolving Dinoflagellate Chloroplast Genes: A Possible Common Origin for Sporozoan and Dinoflagellate Plastids

The results for all three genes fit the idea that dinoflagellate chloroplasts originated from red algae by a secondary endosymbiosis, possibly the same one as for chromists and Sporozoa.

‘Total evidence’ refutes the inclusion of Perkinsus species in the phylum Apicomplexa

The phylogenetic affinities of the oyster pathogen Perkinsus marinus were investigated with morphology, 18S-like rDNA data and actin sequence data and the resulting cladogram strongly corroborates the placement of Perkinsus species with the Dinoflagellida and not with the Apicomplexa.

Evolutionary Relationships Among the Eukaryotic Crown Taxa Taking into Account Site-to-Site Rate Variation in 18S rRNA

A bootstrapped distance tree of 500 small subunit ribosomal RNA sequences from organisms belonging to the so-called crown of eukaryote evolution suggests that animals, true fungi, and choanoflagellates share a common origin and that the animals no longer appear as a monophyletic grouping in most distance trees.

Phylogenetic analysis of Perkinsus based on actin gene sequences.

Phylogenetic comparisons of nucleotide sequence data for actin genes from Perkinsus marinus and 2 dinoflagellates and Amphidinium carterae indicated a closer affinity of P. marinus to din oflageLLates than to apicomplexans.

Ultrastructure and identification of the predatory flagellateColpodella pugnax Cienkowski (Apicomplexa) with a description ofColpodella turpis n. sp. and a review of the genus

It is confirmed that Colpodella is the genus with free-living species most closely related to the apicomplexan parasites (i.e. the “Euapicom Complexa” and “Perkinsus”), and no unambiguous synapomorphy supports an “apicOMplexan parasite” clade.
