Phytoplankton Under Pressure: Temperature, Precipitation and Cyanobacterial Blooms as Drivers of Chytrid Infections. [PDF]

Environ Microbiol Rep
Chytrid parasites of phytoplankton infect a wide range of species, including green algae, diatoms, and cyanobacteria. Infection patterns varied, indicating that chytrid occurrence is highly dynamic in space and time. Warmer temperatures, increased rainfall and cyanobacterial bloom events coincided with enhanced infection prevalence on green algae ...

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems. [PDF]

Mol Ecol Resour
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Quantification of the dark fungal taxon Cryptomycota using qPCR. [PDF]

Environ Microbiol Rep
In recent years, studies have shown that fungi, including the dark fungal taxon Cryptomycota, are abundant but poorly studied in aquatic ecosystems. We developed and validated a Cryptomycota‐specific qPCR primer pair targeting the 5.8S region that detects most Cryptomycota but not Microsporidia in environmental samples.

The Functional Role of Fungi and Bacteria in Sulfur Cycling During Kelp (Ecklonia Radiata) Degradation: Unconventional Use of PiCrust2. [PDF]

Environ Microbiol Rep
The microbial remineralization of Ecklonia radiata produces substantial amounts of climate‐relevant compounds, including dimethylsulfoniopropionate, carbon, sulphur and alkalinity. While bacterial metabolic pathways are well‐characterised and relatively predictable, fungal contributions remain underexplored due to the lack of metabolic predictive tools

Potential disruptive effects of zoosporic parasites on peatland-based organic freshwater aquaculture: Case study from the Republic of Ireland

Science of The Total Environment, 2023
Irish freshwater aquaculture holds great potential for aiding food security. However, its necessary expansion has been hampered by the adoption of important environmental EU directives. A novel peatland-based recirculating aquaculture multi-trophic pond system (RAMPS) was developed to assess its potential to assist in the sustainable development of ...

Symbiotic status alters fungal eco‐evolutionary offspring trajectories

Ecology Letters, Volume 26, Issue 9, Page 1523-1534, September 2023., 2023
Evolutionary transitions in symbiotic status alter the evolution and ecology of fungal spore size. First, transitions in symbiotic status correlate with shifts in spore size during fungal evolution while symbiotic status explains more variation in spore size than climate variables among extant taxa.

The Effect of Organic Compounds on the Encystment, Viability and Germination of Zoospores of Phytophthora cinnamomi [PDF]

Microbiology, 1982
SUMMARY: A number of organic compounds were tested to determine their ability to induce encystment or germination of zoospores of the fungus, Phytophthora cinnamomi. The basic amino acids, lysine and arginine, induced encystment at concentrations in the millimolar range.

Vertical and temporal distribution of chytrids infecting diatoms in the Gulf of Naples (Italy, Mediterranean Sea)

Marine Ecology, Volume 44, Issue 3, June 2023., 2023
Abstract The presence of phytoplankton parasites along the water column was explored at the Long‐Term Ecological Station MareChiara (LTER‐MC) in the Gulf of Naples (Mediterranean Sea) in October 2019. Microscopy analyses showed diatoms dominating the phytoplankton community in the upper layers (0–20 m).

Chytridiomycosis of marine diatoms : the role of stress physiology and resistance in parasite-host recognition and accumulation of defense molecules [PDF]

, 2017
Little is known about the role of chemotaxis in the location and attachment of chytrid zoospores to potential diatom hosts. Hypothesizing that environmental stress parameters affect parasite-host recognition, four chytrid-diatom tandem cultures ...
