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.

Ophiostoma is a Sordariomycete in the family Ophiostomataceae, and members of this genus are wood-staining fungi often associated with insects, such as beetles. Other insects like mites could aid in spore dispersal. Ophiostoma has been found in different studies looking at endophytes on different tree species, and it is associated with its anamorph Sporothrix, which has been described as producing different secondary metabolites with antimicrobial activity.
