Reticulamoeba is a long-branched Granofilosean (Cercozoa) that is missing from sequence databases. [PDF]

PLoS ONE, 2012
We sequenced the 18S ribosomal RNA gene of seven isolates of the enigmatic marine amoeboflagellate Reticulamoeba Grell, which resolved into four genetically distinct Reticulamoeba lineages, two of which correspond to R. gemmipara Grell and R. minor Grell,

Intestinal Parasite Community Dynamics in the Critically Endangered Chinese Alligator (<i>Alligator sinensis</i>): Multifactorial Insights From 18S rRNA Amplicon Sequencing. [PDF]

Ecol Evol
Our results firstly demonstrate the structure of parasite communities in A. sinensis and clarify how they are shaped by interacting ecological and management factors, providing critical baseline data for future research. ABSTRACT The intestinal parasite communities of vertebrates are shaped by complex interactions among biological, environmental, and ...

Legacies of consecutive summer droughts on soil-borne plant parasitic protists (Oomycota: Stramenopila and Phytomyxea: Rhizaria) and protistan consumers (Cercozoa: Rhizaria) along an experimental plant diversity gradient. [PDF]

New Phytol
Summary Increasing frequencies of severe summer droughts and plant diversity loss disrupt ecosystem functioning and stability of European grasslands. Understanding how these factors interact with pathogens is crucial. We investigated the effects of plant diversity and repeated summer drought on soil‐borne parasites within a grassland biodiversity ...

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 ...

Uncovering the Community Structure and Adaptive Characteristics of Soil Protists Across Natural, Semi-Natural and Highly Degraded Habitats. [PDF]

Environ Microbiol
Habitat type influences protistan diversity and community structure and its effect is stronger than that of geographic distance at large spatial scales. We revealed 9 ecological clusters of soil protists and their environmental preferences and found protistan consumers foraging targets may concentrate under degraded environments.

Functional Roles of Cercozoa in the Rhizosphere and Phyllosphere of Plants [PDF]

Molecular Biology and Evolution, 2017
Protists are a group of highly diverse unicellular eukaryotic organisms. They are globally distributed and inhabit all types of terrestrial and aquatic habitats. Protists represent an enormous functional diversity and occupy various ecological niches as bacterivores, fungivores, algivores, predators, primary producers, saprotrophs or parasites of ...

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater. [PDF]

J Eukaryot Microbiol
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

Assembly Patterns of the Rhizosphere Microbiome Along the Longitudinal Root Axis of Maize (Zea mays L.)

Frontiers in Microbiology, 2021
It is by now well proven that different plant species within their specific root systems select for distinct subsets of microbiota from bulk soil – their individual rhizosphere microbiomes.

A Call for Research: A Resource of Core Microbial Symbionts of the Arabidopsis thaliana Microbiome Ready and Awaiting Experimental Exploration

Phytobiomes Journal, 2021
The characterization of specific subsets of soil microbiota in the rhizosphere and endosphere has led to the recognition of plant species-specific microbiomes. Most attention has been given to microbial prokaryotes and fungi. Only recently was convincing

Phytocercomonas venanatans, a New Species of Cercozoa Associated with Chlorotic Streak of Sugarcane [PDF]

Phytopathology®, 2018
Chlorotic streak is a global disease of commercial sugarcane (Saccharum spp. hybrids). The disease is transmitted by wet soil, water, as well as in diseased planting material. Although first recognized almost 90 years ago and despite significant research effort, the identity of the causal agent has been elusive. Metagenomic high throughput sequencing (
