Abstract Peniculine ciliates have been recognized as a distinct higher taxon of ciliates for almost 50 years. However, phylogenetic relationships within the Subclass Peniculia are still unsettled. To contribute to our understanding of their phylogeny and provide evidence for the position of Urocentrum turbo, we sequenced its small subunit (SS) rRNA gene and the SSrRNA genes from Lembadion bullinum, Frontonia sp., Paramecium caudatum, Paramecium multimicronucleatum, Paramecium putrinum, and… Expand
Phylogenetic Relationships of the Subclass Peritrichia (Oligohymenophorea, Ciliophora) with Emphasis on the Genus Epistylis, Inferred from Small Subunit rRNA Gene Sequences
TLDR
It is concluded that the perstomial area, especially the peristomial lip, might be the important phylogenetic character within the genus Epistylis. Expand
Phylogenetic Relationships of the Subclass Peritrichia (Oligohymenophorea, Ciliophora) Inferred from Small Subunit rRNA Gene Sequences1
TLDR
The phylogenetic relationships among peritrichs remain unresolved and trees were constructed using distance-matrix, maximum-likelihood and maximum-parsimony methods, all of which strongly supported the monophyly of the subclass Peritrichia. Expand
Reconsideration of the Phylogenetic Position of Frontonia-related Peniculia (Ciliophora, Protozoa) Inferred from the Small Subunit Ribosomal RNA Gene Sequences
TLDR
The SS rRNA gene sequence determines that the well-outlined genus Frontonia appears to be a paraphyletic assemblage, in which the morphotype Frontonia didieri is more closely related to Apofrontonia than to its congeners. Expand
Phylogenetic position of the marine ciliate, Cardiostomatella vermiforme (Kahl, 1928) Corliss, 1960 inferred from the complete SSrRNA gene sequence, with establishment of a new order Loxocephalida n. ord. (Ciliophora, Oligohymenophorea).
TLDR
The present work indicates that Cardiostomatella vermiforme, together with a closely related species, Dexiotrichides pangi, always form a separate assemblage as a sister group to the scuticociliates sensu stricto, and suggests that this group represents a new order, Loxocephalida n. Expand
Further insights into the phylogeny of peniculid ciliates (Ciliophora, Oligohymenophorea) based on multigene data.
TLDR
27 new sequences are reported, including 18S r RNA, ITS1-5.8S- ITS2 rRNA, 28S rRNA and the mitochondrial cox1 genes of eight peniculids, and multi-gene analyses of Parameciidae support five previously established subgenera. Expand
Phylogeny of Neobursaridium reshapes the systematics of Paramecium (Oligohymenophorea, Ciliophora)
TLDR
To increase the sampling effort for the Paramecium clade, several newly obtained 18S rDNA sequences of parameciids are presented and Hypotheses on the evolution of giant morphologies in ciliates are also discussed. Expand
Reconsideration of the systematics of Peniculida (Protista, Ciliophora) based on SSU rRNA gene sequences and new morphological features of Marituja and Disematostoma
TLDR
It is argued that more diversified morphological features should be considered when assessing diagnostic traits for ciliate taxa during systematic revisions, and the systematic relationships of the genera and families of Peniculida were hypothesized. Expand
Phylogenetic position of the marine ciliate, Certesia quadrinucleata (Ciliophora; Hypotrichia; Hypotrichida) inferred from the complete small subunit ribosomal RNA gene sequence.
The complete small subunit rRNA (SSrRNA) gene sequence of the rare marine hypotrich, Certesia quadrinucleata Fabre-Domergue, 1885, was determined, and found to be 1752 nucleotides long. TheExpand
Large-scale phylogenomic analysis provides new insights into the phylogeny of the class Oligohymenophorea (Protista, Ciliophora) with establishment of a new subclass Urocentria nov. subcl.
TLDR
It is hypothesized that Peritrichia is the earliest diverging clade within Oligohymenophorea while Scuticociliatia and Hymenostomatia share the most common ancestor, followed successively by Urocentria and Peniculia, supporting the evolutionary hypothesis. Expand
Phylogenetic positions of two marine ciliates, Metanophrys similis and Pseudocohnilembus hargisi (Protozoa, Ciliophora,Scuticociliatia), inferred from complete small subunit rRNA gene sequences
TLDR
The results show that this gene comprises 1763 and 1753 nucleotides in the two marine ciliates respectively, which are phylogenetically closely related to the clade containing Mesanophrys carcini and Anophyroides haemophila, which branches basally to other species within the order Philasterida.

Phylogenetic relationships of the genus Paramecium inferred from small subunit rRNA gene sequences.
TLDR
The genus Paramecium includes species that are well known and very common in freshwater environments and are closely related and strongly supported as a monophyletic group. Expand
Phylogenetic position of the ciliates Phacodinium (Order Phacodiniida) and Protocruzia (Subclass Protocruziidia) and systematics of the spirotrich ciliates examined by small subunit ribosomal RNA gene sequences
TLDR
Halteria groups within the stichotrich clade, supporting the argument that the oligotrichs are not monophyletic as currently conceived, and Phacodinium branches after Euplotes at a deep level, confirming the conclusion that others have reached that this genus is related to the hypotrich and stichOTrich spirotrichs.

Phylogeny of the fish parasite Ichthyophthirius and its relatives Ophryoglena and Tetrahymena (Ciliophora, Hymenostomatia) inferred from 18S ribosomal RNA sequences.
TLDR
Phylogenetic relationships within the subclass Hymenostomatia were inferred from the comparisons of three new SSrRNA gene sequences from Ichthyophthirius multifiliis, Ophryoglena catenula, and Tetrahymena corlissi, consistent with their placement in theOphryoglenina. Expand
Evolution of 16S-like ribosomal RNA genes in the ciliophoran taxa litostomatea and phyllopharyngea
TLDR
Using the rRNA phylogenies as framework to understand the evolution of non-molecular features, the low complexity of their oral structures can be interpreted as a secondary adaptation — possibly caused by a shift towards macro-phagous feeding behavior. Expand
Phylogenetic relationships between prostome and colpodean ciliates tested by small subunit rRNA sequences.
TLDR
In all analyses, these four classes branch late in the ciliate tree, which supports the new view of ciliate phylogeny that so-called ancestral taxa, such as the "primitive" prostomes, are in fact derived and thatSo-called "highly evolved" groups,such as the heterotrichs, branch off very early in theciliate tree.

Protein coding gene trees in ciliates: comparison with rRNA-based phylogenies.
TLDR
If alpha-tubulin phylogeny is not informative at the interclass level, the preliminary data from the phosphoglycerate kinase molecule appear more promising, and the resolved phylogenetic relationships inferred from both protein and rRNA sequence data are congruent. Expand
