In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya“ project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems. In addition, comparative genome analysis with saprotrophic, mycorrhizal and pathogenic fungi will provide new insights into the specific and conserved adaptations associated with each fungal lifestyle.

Bisporella sp. PMI857 (1113391)

Bisporella is a widespread genus of ascomycete fungi in the order Helotiales that produces small yellow apothecia on wood substrates1. Most Bisporella species are believed to be saprobic, however many species in this group are also frequently isolated as plant endophytes. Bisporella sp. PMI857 was isolated as an endophytic fungus from living roots of Populus trichocarpa3. Bisporella has been found associated with decaying wood being promoted by beetles, like Agathidium nigripenne4, but it has also been isolated from plants like Myrtus and Pinus2,5. Isolate PMI857 is related to other Bisporella species, but additional taxonomic study is still needed to confirm these relations.
