Foraminifera and Cercozoa share a common origin according to RNA polymerase II phylogenies [PDF]
INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2003 Phylogenetic analysis of small and large subunits of rDNA genes suggested that Foraminifera originated early in the evolution of eukaryotes, preceding the origin of other rhizopodial protists. This view was recently challenged by the analysis of actin and ubiquitin protein sequences, which revealed a close relationship between Foraminifera and Cercozoa,

Microorganisms, 2021 Marine protists are essential for globally critical biological processes, including the biogeochemical cycles of matter and energy. However, compared with their prokaryotic counterpart, it remains largely unclear how environmental factors determine the ...

Confirmation that the Novel Cercozoa Phytocercomonas venanatans Is the Cause of the Disease Chlorotic Streak in Sugarcane [PDF]
Phytopathology®, 2018 A cercomonad, named Phytocercomonas venanatans, is confirmed as the cause of the sugarcane disease chlorotic streak. This was achieved by establishing aseptic liquid cultures of the pathogen isolated from internal pieces of sugarcane stalk tissue. Actively motile cultures of the pathogen were inoculated into sugarcane roots, stalks, and leaf whorls ...

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments
Environmental DNA, Volume 8, Issue 3, May–June 2026.We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

Diversity of protist genera in periphyton of tufa-depositing karstic river
Annals of Microbiology, 2023 Purpose In aquatic ecosystems, protists play a crucial role and cover numerous ecological functions. The karstic Krka River (Croatia) is a unique hotspot for high diversity of aquatic organisms, especially protists.

Soil microbial communities shift along an urban gradient in Berlin, Germany
Frontiers in Microbiology, 2022 The microbial communities inhabiting urban soils determine the functioning of these soils, in regards to their ability to cycle nutrients and support plant communities. In an increasingly urbanized world these properties are of the utmost importance, and

Environmental DNA, Volume 8, Issue 3, May–June 2026.There are many environmental DNA (eDNA) sources within and around a seabird nest. These DNA traces from soil, plant material, feathers, feces, and other nest components enable detection of a wide range of taxa, including plants, fungi, insects, arachnids, mollusks, reptiles, and other vertebrates. Here, we used DNA from nest box feces to obtain signals

Environmental DNA, Volume 8, Issue 3, May–June 2026.Direct eDNA metabarcoding is the most scalable method for large benthic monitoring programs, provided that sampling effort is increased to compensate for slightly lower per‐sample biodiversity recovery. ABSTRACT DNA metabarcoding offers prospects to assess benthic biodiversity in a more scalable and comprehensive way, but processing methods remain ...
