A Reassessment of Phylogenetic Relationships in Class Oligohymenophorea (Protista, Ciliophora) Based on Updated Multigene Data [PDF]

Ecology and Evolution
Within the ciliate class Oligohymenophorea, many evolutionary relationships among taxa remain unresolved. This study incorporates 97 new sequences from 30 oligohymenophorean populations, including nuclear small subunit ribosomal (SSU‐rRNA) genes, nuclear

Further insights into the phylogeny of facultative parasitic ciliates associated with tetrahymenosis (Ciliophora, Oligohymenophorea) based on multigene data [PDF]

Ecology and Evolution, 2023
Tetrahymenosis, caused by about 10 Tetrahymena species, is an emerging problem inflicting a significant economic loss on the aquaculture industry worldwide.

Identification of a non-canonical ciliate nuclear genetic code where UAA and UAG code for different amino acids. [PDF]

PLoS Genetics, 2023
The genetic code is one of the most highly conserved features across life. Only a few lineages have deviated from the "universal" genetic code. Amongst the few variants of the genetic code reported to date, the codons UAA and UAG virtually always have ...

Soil Alveolata diversity in the undisturbed steppe and wheat agrocenoses under different tillage [PDF]

Вавиловский журнал генетики и селекции, 2023
Microeukaryotes are vital for maintaining soil quality and ecosystem functioning, however, their communities are less studied than bacterial and fungal ones, especially by high throughput sequencing techniques.

Morphology and molecular phylogeny of two freshwater ciliates, with notes on a new species and redescription of a known species (Ciliophora, Oligohymenophorea) [PDF]

BMC Microbiology
The class Oligohymenophorea comprises a diverse array of ciliates, however, the diversity and phylogeny of freshwater taxa, particularly from inland waters, remain inadequately explored.

Genetic Features of the Scuticociliate Pathogen Philaster sp. Isolate FWC2 That Causes Sea Urchin Mass Mortality. [PDF]

J Eukaryot Microbiol
ABSTRACT A scuticociliate most closely related to Philaster apodigitiformis caused mass mortalities of diadematoid sea urchins and was cultured as Philaster sp. isolate FWC2. We sequenced the metagenomic content of this isolate, which was predicted to represent ≤ 56% of the complete genome.

Environmental RNA-Based Metatranscriptomics as a Novel Biomonitoring Tool: A Case Study of Glyphosate-Based Herbicide Effects on Freshwater Eukaryotic Communities. [PDF]

Mol Ecol
ABSTRACT Traditional morphology‐ and molecular‐based biodiversity surveys provide essential information on species composition and diversity, but they rarely provide information about the physiological states of organisms, which are key indicators of ecosystem health.

Parasitic taxa are key to the vertical stratification and community variation of pelagic ciliates from the surface to the abyssopelagic zone [PDF]

Environmental Microbiome
Background An increase in upper-ocean thermal stratification is being observed worldwide due to global warming. However, how ocean stratification affects the vertical profile of plankton communities remains unclear.

Isolation and Characterisation of Serotype III in Miamiensis avidus (Ciliophora: Scuticociliatida) From Olive Flounder (Paralichthys olivaceus). [PDF]

J Fish Dis
ABSTRACT Miamiensis avidus (Ciliophora: Scuticociliatida, syn. Philasterides dicentrarchi) is a significant pathogen causing scuticociliatosis in olive flounder (Paralichthys olivaceus) in Korea and Japan. In this study, the BB19 strain, isolated from olive flounder, was identified as M.

Morphology and Molecular Phylogeny of Endosymbiotic Ciliates (Peritrichia, Mobilida) of Marine Invertebrates with Descriptions of Two Novel Species Urceolaria clepsydra n. sp. and Urceolaria bratalia n. sp. [PDF]

J Eukaryot Microbiol
ABSTRACT Mobilid ciliates are a morphologically distinct group of protists that form a wide range of symbiotic relationships with aquatic animals and includes three subgroups: Trichodinidae, Urceolariidae, and Polycyclidae. Trichodinids are best known for infecting fishes, whereas urceolariids infect diverse marine invertebrates.
