Ebriid Phylogeny and the Expansion of the Cercozoa

Protist, 2006
Ebria tripartita is a phagotrophic flagellate present in marine coastal plankton communities worldwide. This is one of two (possibly four) described extant species in the Ebridea, an enigmatic group of eukaryotes with an unclear phylogenetic position.

Ultrastructure of the Algivorous Amoeboflagellate Viridiraptor invadens (Glissomonadida, Cercozoa)

Protist, 2014
The family Viridiraptoridae represents a morphologically and ecologically distinct lineage of glissomonad flagellates (Cercozoa, Rhizaria). It currently comprises two highly specialised, algivorous genera inhabiting freshwater ecosystems, Orciraptor and Viridiraptor, for which ultrastructural data were lacking.

New Genera, Species, and Improved Phylogeny of Glissomonadida (Cercozoa)

Protist, 2011
Glissomonadida is an important cercozoan order of predominantly biflagellate gliding bacterivores found largely in soil and freshwater. Their vast diversity is largely undescribed. We studied 23 mostly newly isolated strains by light microscopy and sequenced their 18S rDNA genes; nine represent new species.

Transfer of the thecate amoebae Lecythium spinosum and Pamphagus armatus to Rhizaspis (Thecofilosea, Cercozoa, Rhizaria).

European Journal of Protistology, 2021
Thecofilosea is a class in Cercozoa (Rhizaria) comprising mainly freshwater-inhabiting algivores. Recently, numerous isolates of thecofilosean amoebae have been cultured and were characterized by an integrated morphological and molecular approach.

Polyubiquitin Insertions and the Phylogeny of Cercozoa and Rhizaria

Protist, 2005
A single or double amino acid insertion at the monomer-monomer junction of the universal eukaryotic protein polyubiquitin is unique to Cercozoa and Foraminifera, closely related 'core' phyla in the protozoan infrakingdom Rhizaria. We screened 11 other candidate rhizarians for this insertion: Radiozoa (polycystine and acantharean radiolaria), a ...

Cercozoa comprises both EF-1α-containing and EFL-containing members

European Journal of Protistology, 2011
Elongation factor 1α (EF-1α) and elongation factor-like protein (EFL) are considered to be functionally equivalent proteins involved in peptide synthesis. Eukaryotes can be fundamentally divided into 'EF-1α-containing' and 'EFL-containing' types. Recently, EF-1α and EFL genes have been surveyed across the diversity of eukaryotes to explore the origin ...

A novel parasitoid, Pseudopirsonia chaetoceri n. sp. (Imbricatea, Cercozoa), of marine diatoms discovered in Korean coastal waters

ALGAE
The cercozoan parasitoid Pseudopirsonia infects marine diatoms. Currently, only one species, P. mucosa, in the genus has been formally described in the North Sea.

Ultrastructure of Allapsa vibrans and the Body Plan of Glissomonadida (Cercozoa)

Protist, 2012
Biciliate, gliding zooflagellate Cercozoa are globally the most abundant and genetically diverse predators in soil (glissomonads and cercomonads). We present the first detailed ultrastructural study of a phylogenetically well-characterized glissomonad, Allapsa vibrans.

First record of Genus Sphenoderia Schlumberger, 1845 (Phylum Cercozoa: Euglyphida) from India

Zootaxa
The genus Sphenoderia Schlumberger, 1845 has been recorded for the first time in India. The type species Sphenoderia lenta Schlumberger, 1845 is noticed in the forest biotope of Arunachal Pradesh, and Sphenoderia minuta Deflandre, 1931 and Sphenoderia ...

Two marine protists (Rhizaria: Cercozoa: Phaeodaria) in the deep Fram Strait (Arctic Ocean)

Journal of the Marine Biological Association of the United Kingdom
We report on the collection of two phaeodarian protists from the deep Fram Strait (Arctic Ocean). Specimens were collected using high-volume plankton pumps in the Long-Term Ecological Observatory HAUSGARTEN in 2021.
