Taxonomic and Functional Diversity of Heterotrophic Protists (Cercozoa and Endomyxa) from Biological Soil Crusts [PDF]

Microorganisms, 2021
Biological soil crusts (biocrusts) accommodate diverse communities of phototrophic and heterotrophic microorganisms. Heterotrophic protists have critical roles in the microbial food webs of soils, with Cercozoa and Endomyxa often being dominant groups ...

On the phenology of protists: recurrent patterns reveal seasonal variation of protistan (Rhizaria: Cercozoa and Endomyxa) communities in tree canopies [PDF]

FEMS Microbiology Ecology, 2021
ABSTRACT Tree canopies are colonized by billions of highly specialized microorganisms that are well adapted to the highly variable microclimatic conditions, caused by diurnal fluctuations and seasonal changes. In this study, we investigated seasonality patterns of protists in the tree canopies of a temperate floodplain forest via high-

Revised Taxonomy and Expanded Biodiversity of the Phytomyxea (Rhizaria, Endomyxa)

Journal of Eukaryotic Microbiology, 2020
AbstractPhytomyxea (phytomyxids) is a group of obligate biotrophic pathogens belonging to the Rhizaria. Some phytomyxids are well studied and include known plant pathogens such as Plasmodiophora brassicae, the causal agent of clubroot disease. Despite this economic importance, the taxonomy and biodiversity of this group are largely cryptic, with many ...

Contrasting Responses of Protistan Plant Parasites and Phagotrophs to Ecosystems, Land Management and Soil Properties

Frontiers in Microbiology, 2020
Functional traits are increasingly used in ecology to link the structure of microbial communities to ecosystem processes. We investigated two important protistan lineages, Cercozoa and Endomyxa (Rhizaria) in soil using Illumina sequencing and analyzed ...

Shedding Light on Vampires: The Phylogeny of Vampyrellid Amoebae Revisited [PDF]

PLoS ONE, 2012
With the advent of molecular phylogenetic techniques the polyphyly of naked filose amoebae has been proven. They are interspersed in several supergroups of eukaryotes and most of them already found their place within the tree of life.

Dinopallor Comventus n. gen., n. sp., a Novel Parasitoid of Marine Dinoflagellates Representing a Sister Lineage to Seagrass Parasites and Expanding the Host Range of Phytomyxea (Rhizaria, Endomyxa)

Microbial Ecology
Phytomyxea (SAR: Rhizaria: Endomyxa) is a group of obligate biotrophic parasitic protists comprised of two orders: Plasmodiophorida, found in terrestrial or freshwater environments, and Phagomyxida, found in marine environments. While Plasmodiophorida has been extensively studied due to its economic importance as plant pathogens, Phagomyxida remains ...

Comparative genomics of Ascetosporea gives new insight into the evolutionary basis for animal parasitism in Rhizaria

BMC Biology
Background Ascetosporea (Endomyxa, Rhizaria) is a group of unicellular parasites infecting aquatic invertebrates. They are increasingly being recognized as widespread and important in marine environments, causing large annual losses in invertebrate ...

Sorosphaerula nom. n. for the plasmodiophorid genus Sorosphaera J. Schröter 1886 (Rhizaria: Endomyxa: Phytomyxea: Plasmodiophorida). [PDF]

The Journal of eukaryotic microbiology, 2012
Sorosphaerula nom. n. is introduced to replace the phytomyxean generic name Sorosphaera J. Schröter, which is preoccupied by the foraminiferan genus Sorosphaera Brady. As it is agreed now that both the Foraminifera and the Phytomyxea belong to the Rhizaria, this homonomy within the same supergroup of eukaryotes needs to be revised.

Long amplicons as a tool to identify variable regions of ribosomal RNA for improved taxonomic resolution and diagnostic assay design in microeukaryotes: using ascetosporea as a case study

Frontiers in Ecology and Evolution, 2023
IntroductionThere is no universally appropriate basis for delimiting species in protists, including parasites. Many molecular markers used for species delimitation are part of the ribosomal RNA (rRNA) array, with different regions of the array being used

Making sense of environmental sequencing data: Ecologically important functional traits of the protistan groups Cercozoa and Endomyxa (Rhizaria) [PDF]

Molecular Ecology Resources, 2019
AbstractWe have compiled a database of functional traits for two widespread and ecologically important groups of protists, Cercozoa and Endomyxa (Rhizaria). The functional traits of microorganisms are crucially important for interpreting results from environmental sequencing surveys.
