In the project “1KFG: Deep Sequencing of Ecologically-relevant Dikarya” (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.

With a circumboreal distribution, Fomitopsis rosea Alb. & Schwein. P.Karst. 1881 (= Rhodofomes roseus (Alb. & Schwein.) Kotl. & Pouzar) (Polyporales) produces perennial fruit bodies on dead wood of conifers, especially on Picea abies. The species is mostly confined to well preserved old-growth coniferous forests and is considered as a threatened polypore species in Fennoscandian forests. It is characterized by producing tough and sessile basidiocarps with pale pink to brownish pink pore surface. The hyphal system is trimitic with generative hyphae bearing clamps. Basidiospores, 5.5-7.5 x 2-2.5 µm, are sub-cylindrical to ovoid. The sequenced strain has been provided by Dr. Sundy Maurice and Prof. Håvard Kauserud at the University of Oslo.

The availability of a reference genome will first help to support our ongoing research based on population genetics study of wood decay fungi at a European scale (Norway, Sweden, Finland, Russia and Poland) using RAD sequencing. Using a reference genome, we will investigate the effect of forest fragmentation and habitat loss on genetic diversity as well as long and recent population trends. Biological knowledge arising from this genomics project is of significant interest in a forest management context and may influence the conservation of the Red List of threatened species. Analysis of the sequenced genome of F. rosea will help to determine its phylogenetic placement within the order Polyporales.

The 1KFG project is a large collaborative effort aiming for master publication(s). Please do contact the PI associated with unpublished 1KFG genomes for permission prior to the use of any data in publications.
