Long transposon-rich centromeres in an oomycete reveal divergence of centromere features in Stramenopila-Alveolata-Rhizaria lineages.

PLoS Genetics, 2020
Centromeres are chromosomal regions that serve as platforms for kinetochore assembly and spindle attachments, ensuring accurate chromosome segregation during cell division.

New evaluation of vertical particulate organic carbon fluxes of submillimeter-sized phaeodarians in the mesopelagic twilight zone of the western North Pacific Ocean

Progress in Earth and Planetary Science
The western subarctic North Pacific is one of the areas where substantial amounts of CO2 are photosynthetically taken up and effectively transferred to the ocean interior.

Comparative genomics reveals the unique evolutionary status of Plasmodiophora brassicae and the essential role of GPCR signaling pathways

Phytopathology Research, 2019
Plasmodiophora brassicae is an important biotrophic eukaryotic plant pathogen and a member of the rhizarian protists. This biotrophic pathogen causes clubroot in cruciferous plants via novel intracellular mechanisms that are markedly different from those

Collect of Collodarian (Rhizaria, Radiolaria) nuclei for genomic analyses v1 [PDF]

, 2019
Collodaria are ubiquitous and abundant marine radiolarian (Rhizaria) protists (Biard et al. 2015). They occur as large colonies (a few millimeters up to 3 meters long) or as solitary specimens. Collodarians are known to play an important role in oceanic food webs both as active predators and as hosts of intracellular endosymbiotic microalgae primarily ...

Functional Traits and Spatio-Temporal Structure of a Major Group of Soil Protists (Rhizaria: Cercozoa) in a Temperate Grassland

Frontiers in Microbiology, 2019
Soil protists are increasingly appreciated as essential components of soil foodwebs; however, there is a dearth of information on the factors structuring their communities. Here we investigate the importance of different biotic and abiotic factors as key

Radiolaria divided into Polycystina and Spasmaria in combined 18S and 28S rDNA phylogeny.

PLoS ONE, 2011
Radiolarians are marine planktonic protists that belong to the eukaryote supergroup Rhizaria together with Foraminifera and Cercozoa. Radiolaria has traditionally been divided into four main groups based on morphological characters; i.e.

Rhizaria marine protists are unexpectedly abundant and exhibit taxonomic and trophic diversity in the northern Gulf of Alaska [PDF]

Rhizaria are a diverse supergroup of large marine protists that are often overlooked due to their lower abundances and wide size range relative to other plankton, and fragility.
