Comparative analysis of the mitochondrial cytochrome c oxidase subunit I (COI) gene in ciliates (Alveolata, Ciliophora) and evaluation of its suitability as a biodiversity marker
TLDR
The resolution of COI at the intraspecific level is much greater than that of any nuclear genes and shows great potential to identify species based on molecular data if a reliable database exists, and resolve the relationships of closely related ciliate taxa and uncover cryptic species.
Sequence analyses of the small subunit rRNA gene confirm the paraphyly of oligotrich ciliates sensu lato and support the monophyly of the subclasses Oligotrichia and Choreotrichia (Ciliophora,
TLDR
The choreotrichs are confirmed as a monophyletic subclass whereas the halteriids do not cluster with the strombidiids, but within the subclass Stichotrichia, and the family Halteriidae is transferred to the order Sporadotrichida in the subclass OligotrichIA.
Parallel evolution of histophagy in ciliates of the genus Tetrahymena
TLDR
There has been parallel evolution of histophagy in the genus Tetrahymena and the three classical species complexes are paraphyletic, and the genus Lambornella is not likely a defensible one.
Phylogenetic Position of Species in the Genera Anoplophrya, Plagiotoma, and Nyctotheroides (Phylum Ciliophora), Endosymbiotic Ciliates of Annelids and Anurans
TLDR
It is confirmed that the astome Anoplophrya marylandensis is related to ciliates in the Class Oligohymenophorea, supporting the view that astomes are derived from hymenostome-like ancestors.
What Morphology and Molecules Tell Us about the Evolution of Oligotrichea (Alveolata, Ciliophora)
TLDR
The evolution of the dominant marine plankton ciliates, the oligotrichids and choreotrichidids, is analysed for morphologic and genetic convergences and apomorphies based on literature and data and has taxonomic implications.
Morphologic and Genetic Variability in the Marine Planktonic Ciliate Laboea strobila Lohmann, 1908 (Ciliophora, Oligotrichia), with Notes on its Ontogenesis
TLDR
The morphology of specimens from the Mediterranean Sea, North Sea, and Irish Sea was investigated using live observation, protargol impregnation, and scanning electron microscopy, and the PCR-amplified products of the SSrRNA gene from a monoclonal culture of L. strobila were sequenced and aligned with sequences of other oligotrichs.
Pelagostrobilidium neptuni (Montagnes and Taylor, 1994) and Strombidium biarmatum nov. spec. (Ciliophora, Oligotrichea): phylogenetic position inferred from morphology, ontogenesis, and gene sequence
TLDR
The phylogenetic analysis of the small subunit ribosomal RNA genes matched the morphologic and ontogenetic assigning of P. neptuni to the choreotrichid family Strobilidiidae and S. biarmatum is placed within the order Oligotrichida by gene sequence analysis.
Species of Tetrahymena Identical by Small Subunit rRNA Gene Sequences are Discriminated by Mitochondrial Cytochrome c Oxidase I Gene Sequences
TLDR
The CO1 genes of two isolates of each of the seven mating types of Tetrahymena thermophila were sequenced and found to differ by < 1% in nucleotide sequence and to be identical by putative protein sequence.
