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

Post-LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor. [PDF]
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

Microbial Community Dynamics in Early Tufa Biofilms. [PDF]
Microbial succession shapes the early development of tufa biofilms in karst freshwater systems, with prokaryotic communities stabilizing rapidly and microeukaryotes contributing to extracellular polymeric substance production and carbonate entrapment. Site‐specific hydrodynamics and organic inputs drive community specialization, ultimately influencing ...

The alveolates (Superphylum Alveolata) comprise a group of primarily single-celled eukaryotes that have adopted extremely diverse modes of nutrition, such as predation, photoautotrophy and parasitism.

Reassessing Interkingdom Horizontal Gene Transfer Suggests Limited Influence on Plant Genomes. [PDF]
Horizontal gene transfer (HGT) has been proposed as an important contributor to plant genome evolution, with hundreds of candidate genes reported across kingdoms. By reanalyzing published cases with updated genomic data and phylogenetic reconstructions, we found that only 29.3% remain consistent with interkingdom HGT.

Unveiling Protist Composition and Diversity Patterns With eDNA Metabarcoding: Comparing Short- and Long-Read Approaches. [PDF]
Environmental DNA (eDNA) metabarcoding is widely used for biodiversity monitoring, but short‐read sequencing limits detailed taxonomic identification, especially for protists. In a comparison of short‐ and long‐read approaches in the Belgian North Sea, long‐read metabarcoding provided deeper taxonomic assignment under the applied workflows and improved

Somatic infraciliature in tintinnid ciliates (Alveolata, Ciliophora, Spirotricha): An ultrastructural comparison* [PDF]
AbstractA recent ultrastructural study on the tintinnid ciliate Schmidingerella meunieri displayed unique types of somatic kinetids. The dikinetids (paired basal bodies) have, besides kinetodesmal fibrils and transverse ribbons, some special features, that is, overlapping postciliary ribbons and three extraordinary microtubular ribbons, which together ...

Protist community composition during early phytoplankton blooms in the naturally iron-fertilized Kerguelen area (Southern Ocean) [PDF]
Microbial eukaryotic community composition was examined by 18S rRNA gene tag pyrosequencing, during the early phase of spring phytoplankton blooms induced by natural iron fertilization, off Kerguelen Island in the Southern Ocean (KEOPS2 cruise).
