Special Issue Information

Dear Colleagues,

Two aspects make this Special Issue proposal especially relevant, scientifically as well as in terms of its applications. Scientifically: Huge concerted efforts have been invested into genome sequencing, hereby unravelling the evolutionary structures of the Tree of Life. However, the basal lineages of the Tree of Life remain unresolved, not least that of the zoosporic fungi and the Straminopiles Protists. The tools are ready for making breakthroughs in this exciting area. Health: Zoosporic fungi are causal agents of the most devastating diseases among all vertebrates (e.g., Batrachochytrium dendrobatidis). Its pathogenicity has not been fully elucidated. Biodiversity: Zoosporic fungi and protists are prominent and widespread among the aquatic (and also soil) ecological systems. However, their ecological role remains heavily understudied. Zoosporic microorganisms have an underutilized potential for serving as markers for the health of oceans and freshwaters. Their naked zoospore react promptly to ecosystem disturbances, unbalances and toxins. Applied: Zoosporic fungi are also of relevance for the green turn around and climate change mitigation: feeding a growing population and at the same time setting aside sufficient space for biodiversity has resulted in a renewed focus on the sustainable use of marine and freshwater aquatic biological resources. Cultivating microalgae is one of the promising areas; however, zoosporic chytrid fungi constitute a threat and a limiting factor for upscaled cultivation. Furthermore, recent studies have revealed zoosporic fungi (and maybe also protists) have a surprisingly rich and diverse enzyme portfolio. Such enzymes remain unexploited. The papers invited for this volume will focus on a broad selection of topics: the evolution as well as taxonomy and phylogeny of the basal zoosporic lineages. The ecology of zoosporic fungi and protists. The molecular biology of such aquatic microorganisms, highlighting new discoveries of e.g., a range of light-sensing molecules, health-promoting oils, and biomass-modifying, secreted enzymes, including CAZymes, lipases and proteases.

The Chytridiomycota phylum contributes to nutrient cycling and the flow of energy between trophic levels in terrestrial and aquatic ecosystems yet remains poorly described or absent from publications discussing fungal communities in these environments. This study contributes to the understanding of three species of soil chytrids in vitro—Gaertneriomyces semiglobifer, Spizellomyces sp. and Rhizophlyctis rosea—in the presence of elevated concentrations of nitrogen and phosphorus and with different sources of nitrogen. Colony growth was measured after 4 weeks as dry weight and total protein. To determine the impacts on zoospore reproduction, motility, lipid content, and attachment to organic substrates, 4- and 8-week incubation times were investigated. Whilst all isolates were able to assimilate ammonium as a sole source of nitrogen, nitrate was less preferred or even unsuitable as a nutrient source for G. semiglobifer and R. rosea, respectively. Increasing phosphate concentrations led to diverse responses between isolates. Zoospore production was also variable between isolates, and the parameters for zoospore motility appeared only to be influenced by the phosphate concentration for Spizellomyces sp. and R. rosea. Attachment rates increased for G. semiglobifer in the absence of an inorganic nitrogen source. These findings highlight variability between the adaptive responses utilised by chytrids to persist in a range of environments and provide new techniques to study soil chytrid biomass and zoospore motility by total protein quantification and fluorescent imaging respectively.

Although aquatic and parasitic fungi have been well known for more than 100 years, they have only recently received increased awareness due to their key roles in microbial food webs and biogeochemical cycles. There is growing evidence indicating that fungi inhabit a wide range of marine habitats, from the deep sea all the way to surface waters, and recent advances in molecular tools, in particular metagenome approaches, reveal that their diversity is much greater and their ecological roles more important than previously considered. Parasitism constitutes one of the most widespread ecological interactions in nature, occurring in almost all environments. Despite that, the diversity of fungal parasites, their ecological functions, and, in particular their interactions with other microorganisms remain largely speculative, unexplored and are often missing from current theoretical concepts in marine ecology and biogeochemistry. In this review, we summarize and discuss recent research avenues on parasitic fungi and their ecological potential in marine ecosystems, e.g., the fungal shunt, and emphasize the need for further research.
