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 ...

First Draft Genome Sequence of a Polymyxa Genus Member, Polymyxa betae, the Protist Vector of Rhizomania. [PDF]

Microbiol Resour Announc, 2019
Polymyxa betae belongs to the Plasmodiophorida (Phytomyxea, Rhizaria). Here, we report the first draft genome sequence of a member of the Polymyxa genus, which includes two obligate root endoparasite species, vectors of important soilborne plant viruses.

Phagocytosis underpins the biotrophic lifestyle of intracellular parasites in the class Phytomyxea (Rhizaria). [PDF]

New Phytol, 2023
Summary Phytomyxea are intracellular biotrophic parasites infecting plants and stramenopiles, including the agriculturally impactful Plasmodiophora brassicae and the brown seaweed pathogen Maullinia ectocarpii. They belong to the clade Rhizaria, where phagotrophy is the main mode of nutrition.

Diurnal Rhythmicity in the Rhizosphere Microbiome-Mechanistic Insights and Significance for Rhizosphere Function. [PDF]

Plant Cell Environ
ABSTRACT The rhizosphere is a key interface between plants, microbes and the soil which influences plant health and nutrition and modulates terrestrial biogeochemical cycling. Recent research has shown that the rhizosphere environment is far more dynamic than previously recognised, with evidence emerging for diurnal rhythmicity in rhizosphere chemistry

Metagenomics approach for Polymyxa betae genome assembly enables comparative analysis towards deciphering the intracellular parasitic lifestyle of the plasmodiophorids [PDF]

, 2022
Genomic knowledge of the tree of life is biased to specific groups of organisms. For example, only six full genomes are currently available in the rhizaria clade.

Response of protists to nitrogen addition, arbuscular mycorrhizal fungi manipulation, and mesofauna reduction in a tropical montane rainforest in southern Ecuador

Journal of Eukaryotic Microbiology, Volume 70, Issue 6, November/December 2023., 2023
Abstract The tropical Andes are a species‐rich and nitrogen‐limited system, susceptible to increased nitrogen (N) inputs from the atmosphere. However, our understanding of the impacts of increased N input on belowground systems, in particular on protists and their role in nutrient cycling, remains limited.

Eelgrass (Zostera spp.) associated phytomyxids are host‐specific congeneric parasites and predominant eukaryotes in the eelgrass rhizosphere on a global scale

Environmental Microbiology, Volume 25, Issue 8, Page 1522-1537, August 2023., 2023
Abstract Together with increasing environmental and anthropogenic pressures, pathogenic diseases are one of the important factors contributing to the ongoing decline of seagrass meadows worldwide; yet the diversity and ecology of the microorganisms acknowledged as seagrass parasites remain critically understudied.

Alveolates (dinoflagellates, ciliates and apicomplexans) and Rhizarians are the most common microbial eukaryotes in temperate Appalachian karst caves

Environmental Microbiology Reports, Volume 14, Issue 4, Page 538-548, August 2022., 2022
Summary The purpose of this study was to survey the eukaryotic microbiome of two karst caves in the Valley and Ridge physiographic region of the Appalachian Mountains. Caves are known to harbour eukaryotic microbes but their very low densities and small cell size make them difficult to collect and identify.

Phylogenetic tree of the partial 18S rDNA gene sequences from the novel Maullinia sp. which is parasitic in Durvillaea antarctica. [PDF]

, 2013
Maullinia sp. (JX163857) is placed within the Phagomyxida and sister to the second brown algal parasitic species of Phytomyxea Maullinia ectocarpii. The phylogenetic tree was constructed using Bayesian analyses running the GTR+I+R model with 1000000 ...
