SSU rDNA divergence in planktonic foraminifera: molecular taxonomy and biogeographic implications. [PDF]

PLoS ONE, 2014
The use of planktonic foraminifera in paleoceanography requires taxonomic consistency and precise assessment of the species biogeography. Yet, ribosomal small subunit (SSUr) DNA analyses have revealed that most of the modern morpho-species of planktonic ...

Ciliate Environmental Diversity Can Be Underestimated by the V4 Region of SSU rDNA: Insights from Species Delimitation and Multilocus Phylogeny of Pseudokeronopsis (Protist, Ciliophora) [PDF]

Microorganisms, 2019
Metabarcoding and high-throughput sequencing methods have greatly improved our understanding of protist diversity. Although the V4 region of small subunit ribosomal DNA (SSU-V4 rDNA) is the most widely used marker in DNA metabarcoding of eukaryotic ...

Taxonomy and SSU rDNA-Based Phylogeny of Two Heterotrich Ciliates (Ciliophora, Heterotrichea) Collected From Subtropical Wetlands of China, Including the Description of a New Species, Linostomella pseudovorticella n. sp. [PDF]

Frontiers in Microbiology, 2021
The Heterotrichea Stein, 1859 are a group of ciliated protists (single-celled eukaryotes) that occur in a wide variety of aquatic habitat where they play important roles in the flow of nutrients and energy within the microbial food web.

A Revised Understanding of Petalomonad Diversity (Petalomonadida; Euglenida) Enabled by a Cultivation Approach, With Five New Species and Two New Genera. [PDF]

J Eukaryot Microbiol
ABSTRACT Euglenids are an important group of free‐living phototrophic, osmotrophic, or phagotrophic protists, with most of the phylogenetic diversity represented by phagotrophs. One major subgroup of phagotrophs is the petalomonads: rigid, often relatively small cells with few pellicle strips (usually 4–8).

Morphomolecular Characterization of Two New Species of the Genus Bothrostoma Stokes, 1887 (Ciliophora: Metopidae). [PDF]

J Eukaryot Microbiol
ABSTRACT Although species diversity has been extensively studied in anaerobic ciliates, their full diversity is incompletely understood. More research is required to gain further insights into their diversity. In this study, two new metopid ciliates, namely, Bothrostoma oryzaforme nov. sp. and Bothrostoma turgidoryzaforme nov.

Morphology, Ultrastructure, and Classification of Barthelonids (Metamonada Incertae Sedis): With Descriptions of Microbarthelona Gen. Nov., and Parabarthelona Gen. Nov. [PDF]

J Eukaryot Microbiol
ABSTRACT Barthelona is a genus of anaerobic flagellates that forms a sister lineage to Fornicata along with Skoliomonas. Although “Barthelona spp.” are known to separate into three distinct lineages, their detailed morphology has not been examined, and their taxonomic classification is incomplete.

OligoN-Design: A Simple and Versatile Tool to Design Specific Probes and Primers From Large Heterogeneous Datasets. [PDF]

Mol Ecol Resour
ABSTRACT High‐throughput environmental DNA sequencing has ushered ecological and evolutionary studies into the big data era. With thousands to millions of DNA sequences, designing taxon‐specific oligonucleotides is a current bottleneck of molecular studies that rely on primers for Polymerase Chain Reactions (PCRs) or probes for Fluorescence in situ ...

Morphology and molecular phylogeny of a new ciliate Anteholosticha nanjiensis sp. nov. (Ciliophora, Hypotrichia) collected from the coastal intertidal zone of the East China Sea [PDF]

ZooKeys
A new hypotrich ciliate, Anteholosticha nanjiensis sp. nov., was isolated from a sandy beach in Wenzhou, China. Its morphology was investigated using detailed live observation and protargol staining, and its phylogenetic position was assessed through ...

Single-Strand Conformation Polymorphism Fingerprint Method for Dictyostelids

Frontiers in Microbiology, 2021
Dictyostelid social amoebae are a highly diverse group of eukaryotic soil microbes that are valuable resources for biological research. Genetic diversity study of these organisms solely relies on molecular phylogenetics of the SSU rDNA gene, which is not
