Pythium intermedium, a species complex consisting of three phylogenetic species found in cool-temperate forest ecosystems.

Pythium intermedium plays a vital role in the carbon cycle of cool-temperate forests and is widely distributed in Japan's forest soils. In this study, we performed a phylogenetic analysis of the P. intermedium species complex using DNA sequences from multiple loci.

Genetic Differentiation Associated with Fumonisin and Gibberellin Production in Japanese .

is a pathogenic fungus that infects rice. It produces several important mycotoxins, such as fumonisins. Fumonisin production has been detected in strains of maize, strawberry, and wheat, whereas it has not been detected in strains from rice seedlings infested with bakanae disease in Japan.

Pythium rishiriense sp. nov. from water and P. alternatum sp. nov. from soil, two new species from Japan.

In an investigation of Pythium species in natural ecosystems of Rishiri Island in Northern Japan, two new species, Pythium rishiriense and P. alternatum, were identified based on morphological and molecular analyses. Pythium rishiriense differed morphologically from other Pythium species by its characteristic oogonial formation which occasionally arranged in chains.

Development of microsatellite markers for Pythium helicoides.

A strategy combining dual-suppression PCR and thermal asymmetric interlaced PCR was used to determine sequences flanking microsatellite regions in Pythium helicoides. The primer pairs were designed to amplify loci containing (AC)n, (GA)n, (AGC)n, (CAC)n(CAA)n, (TCA)n and (CTTT)n repeats from the P. helicoides nuclear genome.
