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.

The genus Xylogone is classified in the Leotiomycetes, which is one of the most diverse groups in the Ascomycota. These fungi are understudied and many of them are characterized as dark septate endophytes or have potential for a mycorrhizal lifestyle. Xylogone is closely related to Scytalidium, but recent publications show that the phylogenetic relationship of these genera in relation to other Leotiomycetes is still poorly resolved. Xylogone has been described from plant roots and agricultural soil and with potential antimicrobial activity; however there was a recent report causing yellow rot on the fungus Ganoderma lucidum in Korea. This work is supported by the Genomic Science Program (U.S. Department of Energy) Plant Microbe Interfaces (PMI) Scientific Focus Area (http://pmi.ornl.gov) and by the Joint Genome Institute (U.S. Department of Energy) through their Community Sequencing Program (CSP 1974, 1KFG: Deep Sequencing of Ecologically-relevant Dikarya, F. Martin PI).
