Long-term trends and seasonal variation in host density, temperature, and nutrients differentially affect chytrid fungi parasitising lake phytoplankton

Alena S. Gsell et al.

Summary: Parasites, specifically chytrids, were found to be prevalent in the pelagic plankton community of the lake studied. Chytrid infections occurred throughout the year with the highest prevalence in spring. The prevalence of infections was influenced by factors such as phytoplankton biomass, temperature, and phosphorus concentrations.

Fate of hepatotoxin microcystin during infection of cyanobacteria by fungal chytrid parasites

Ramsy Agha et al.

Summary: Chytrid parasites are recognized as effective control agents of cyanobacteria, but their infection does not lead to a significant increase in toxin production. This suggests that chytrid epidemics do not result in massive toxin release.

Genomic comparison of Planktothrix agardhii isolates from a Lake Erie embayment

Katelyn M. McKindles et al.

Summary: In this study, 20 new Planktothrix agardhii isolates were obtained from early blooms and subjected to genomic sequencing and analysis. The study found that each genome of these isolates had unique characteristics, demonstrating the unexplored diversity of this genus.

Isolation and Characterization of Rhizophydiales (Chytridiomycota), Obligate Parasites of Planktothrix agardhii in a Laurentian Great Lakes Embayment

Katelyn M. McKindles et al.

Summary: Planktothrix agardhii dominates the cyanobacterial harmful algal bloom community in Sandusky Bay, Lake Erie, USA, from May through September, being host to a known obligate parasite, the chytrid Rhizophydium sp. Specific infections by isolated chytrids were limited to Planktothrix planktonic species, with varying degrees of infectivity and preferences for different host isolates, suggesting possible ecological partitioning even within the same sample population. Infection mechanisms by chytrid parasites led to the release of intracellular microcystin toxins from the hosts, highlighting the importance of medium choice for experimental outcomes and the need to understand host-pathogen relationships to effectively model the ecology of cyanobacterial harmful algal blooms.

Co-occurring microorganisms regulate the succession of cyanobacterial harmful algal blooms*

Kai Wang et al.

Summary: CyanoHABs in Harsha Lake shifted from N2 fixer-dominated Anabaena to non-N2 fixer-dominated Microcystis and Planktothrix as nitrogen supply decreased. The concentrations of cyanotoxins were significantly higher when nitrogen became limited. Water quality results indicated significant correlations between nitrogen species, water temperature, and cyanobacterial biomass. Additionally, the expression levels of certain C- and N-processing-related cyanobacterial genes were highly predictive of species biomass.

Environmental factors affecting chytrid (Chytridiomycota) infection rates on Planktothrix agardhii

Katelyn M. McKindles et al.

Summary: Planktothrix-specific chytrids are prevalent throughout the bloom period and can exert parasitic pressure on their hosts. Experiment results show that temperatures above 27.1 degrees Celsius can inhibit chytrid infection, while increased conductivity and turbulence in lab also have inhibitory effects on fungal infections.
