This genome was sequenced as part of the 1000 Fungal Genomes Project - Deep Sequencing of Ecologically-relevant Dikarya. Within the framework of this project, we are sequencing keystone lineages of saprophytic, mycorrhizal, and endophytic fungi that are of special ecological importance. Dozens of sequenced species were harvested from Long Term Observatories to serve as the foundation for a reference database for metagenomics of fungi and for a comprehensive survey of the soil fungal metatranscriptome.
Polyphilus sieberi
The recently described genus Polyphilus belongs to the family Hyaloscyphaceae (Helotiales, Leotiomycetes) and accommodates species considered as anamorphic helotialean ascomycetes without conidia nor spore production. Polyphilus sieberi is a globally distributed species colonizing different organisms: plant roots as endophytes, plant-parasitic nematodes and their cysts and eggs, and maybe inner parts of truffle ascomata. Polyphilus sieberi colonize roots of various plant species of gymnosperms and angiosperms in different ecosystems and are common in roots in woody patches of grassland ecosystems in Hungary, from where the P. sieberi strain DSE2052 originates. Due to its potential positive effect on plant nutrient uptake, performance and survival, and its potential effect on plant parasitic nematodes and other soil organisms, this endophyte might help us to get insight into these important mechanisms of multitrophic symbiosis.
