Contrasting Community Composition of Active Microbial Eukaryotes in Melt Ponds and Sea Water of the Arctic Ocean Revealed by High Throughput Sequencing

Frontiers in Microbiology, 2020
Melt ponds (MPs), form as the result of thawing of snow and sea ice in the summer, have lower albedo than the sea ice and are thus partly responsible for the polar amplification of global warming.

Contrasting Community Composition and Co-Occurrence Relationships of the Active Pico-Sized Haptophytes in the Surface and Subsurface Chlorophyll Maximum Layers of the Arctic Ocean in Summer

Microorganisms, 2022
Haptophytes (Hacrobia: Haptophyta), which can perform phototrophic, phagotrophic, or mixotrophic nutritional modes, are critical for element cycling in a variety of aquatic ecosystems.

An 18S V4 rDNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth

bioRxiv, 2021
Arctic marine protist communities have been understudied due to challenging sampling conditions, in particular during winter and in deep waters. The aim of this study was to improve our knowledge on Arctic protist diversity through the year, both in the ...

Congruence of chloroplast- and nuclear-encoded DNA sequence variations used to assess species boundaries in the soil microalga Heterococcus (Stramenopiles, Xanthophyceae). [PDF]

, 2013
BackgroundHeterococcus is a microalgal genus of Xanthophyceae (Stramenopiles) that is common and widespread in soils, especially from cold regions. Species are characterized by extensively branched filaments produced when grown on agarized culture medium.

Reduced and Nonreduced Genomes in Paraburkholderia Symbionts of Social Amoebas

mSystems, 2022
The social amoeba Dictyostelium discoideum is a predatory soil protist frequently used for studying host-pathogen interactions. A subset of D. discoideum strains isolated from soil persistently carry symbiotic Paraburkholderia, recently formally ...

Endogenous virophages are active and mitigate giant virus infection in the marine protist Cafeteria burkhardae

Proceedings of the National Academy of Sciences of the United States of America
Significance Single-celled eukaryotes are parasitized by viruses just like other life forms, but compared to bacteria or animals, their defense systems against viral infection remain unknown.

Animals and Fungi are Each Other's Closest Relatives: Congruent Evidence from Multiple Proteins [PDF]

, 1993
Phylogenetic relationships among plants, animals, and fungi were examined by using sequences from 25 proteins. Four insertions/deletions were found that are shared by two of the three taxonomic groups in question, and all four are uniquely shared by ...

A New Dawn for Protist Biogeography

Global Ecology and Biogeography
Biogeographers have believed for a long time that the geographical distributions of protists are only determined by environmental conditions, because dispersal is not limited.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

Advanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Establishment and Effect of a Protist Consortium on the Maize Rhizosphere

Phytobiomes Journal
Protists are abundant in the rhizosphere, and protist inoculation onto plants has revealed protists’ roles in plant growth and development, disease suppression, and relationships with plant-beneficial bacteria.
