Outline of Final Research Achievements

We developed Single-spore PCR methods to reveal the diversity of chytridiomycota in lakes and Oceans. In Lake Biwa and Lake Inba, we detected quite diverse fungi, including including novel lineages clades of chytridiomycota and other fungi such as Cryptomycota, infecting dominant diatoms, The extent of host specificity differed among species, that some fungi could infect various hosts. In Tokyo bay, various fungi including Cryptomycota were detected in the surface water. Quantitative PCR together with incubation experiments and mathematical models are useful approach for quantifying the importance of chytrids and roles of chytrids in material cycling in lakes and oceans.
