A case study for effects of operational taxonomic units from intracellular endoparasites and ciliates on the eukaryotic phylogeny: phylogenetic position of the haptophyta in analyses of multiple slowly evolving genes. [PDF]

PLoS ONE, 2012
Recent multigene phylogenetic analyses have contributed much to our understanding of eukaryotic phylogeny. However, the phylogenetic positions of various lineages within the eukaryotes have remained unresolved or in conflict between different ...

Stable Bacterial Cores and Patchy Eukaryotic Communities Shape the Summer Microbiomes of Patagonian Fjord Ecosystems Across Spatial, Functional and Temporal Gradients

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Our study shows that microbial community diversity in Patagonian fjords varies with glacial influence and salinity, with a widespread bacterial core but a patchier eukaryotic core. Distinct co‐occurrence networks and marked short‐term community shifts occur in water‑ versus land‐terminating glacier fjords, underscoring meltwater influence in this ...

Microbial Community Restructuring Under Zinc Oxide Nanoparticle Stress in Membrane Bioreactors

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Long‐term ZnO nanoparticle exposure induced extracellular stress responses and restructured microbial communities, with reduced taxonomic and phylogenetic richness and loss of key nitrogen‐transforming taxa. These ecological changes were accompanied by impaired nitrification, demonstrating that prolonged ZnO exposure can compromise the functional ...

Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Groups without cultured representatives dominate eukaryotic picophytoplankton in the oligotrophic South East Pacific Ocean [PDF]

, 2009
Background: Photosynthetic picoeukaryotes (PPE) with a cell size less than 3 µm play a critical role in oceanic primary production. In recent years, the composition of marine picoeukaryote communities has been intensively investigated by molecular ...

Single cell genome analysis of an uncultured heterotrophic stramenopile [PDF]

Scientific Reports, 2014
A broad swath of eukaryotic microbial biodiversity cannot be cultivated in the lab and is therefore inaccessible to conventional genome-wide comparative methods. One promising approach to study these lineages is single cell genomics (SCG), whereby an individual cell is captured from nature and genome data are produced from the amplified total DNA. Here

Genomic investigations of Plocamiomonas psychrophila and Dictyochophyceae sp. CCMP2098 reveal organellar genome complexity in Arctic Stramenopiles

Scientific Reports
Stramenopiles (Heterokonta) comprise a diverse assemblage of mostly microbial eukaryotes, yet their organellar genomes remain poorly characterized.

Red and green algal origin of diatom membrane transporters: insights into environmental adaptation and cell evolution. [PDF]

PLoS ONE, 2011
Membrane transporters (MTs) facilitate the movement of molecules between cellular compartments. The evolutionary history of these key components of eukaryote genomes remains unclear.

tArp Is an Actin‐Related Protein Required for Ciliary Function That Is Conserved in Ciliates and Related Eukaryotic Groups

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Cells exhibit a wide range of behaviors due to their diverse molecular systems, which have been established through the molecular evolution of individual species. Protein families generated through gene duplications may be involved in this process. The actin cytoskeleton is no exception.

Internal Transcribed sequence (ITS) of Halocafeteria seosinensis (Bicosoecids)

Beni-Suef University Journal of Basic and Applied Sciences, 2017
The aim of the current study was to characterize and identify the smaller subunit (18S) and Internal Transcribed Spacer (ITS) regions, ITS1 and ITS2 (ITS1-5.8S-ITS2) of Halocafeteria seosinensis (Bicosoecida). Halocafeteria was isolated from the salterns
