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.

Phellinidium ferrugineofuscum (=Phellinus ferrugineofuscus; Hymenochaetaceae, Hymenochaetales) is a white-rot basidiomycete species colonizing fallen logs of conifers. It is distributed throughout the boreal conifer forest region, and in Europe it follows the natural stands of spruce (Picea abies). It is considered an indicator of old-growth forest with long ecological continuity and is found on the national red lists of several European countries. The basidiocarps of the species are annual or short-lived perennial, effused dark rusty brown with soft tomentose yellowish edges, not easily separable from the bark. Microscopically, characteristics are cylindrical and hyaline basidiospores 4.5-5.5 x 1-1.5 µm and setal hyphae.

Why sequence the genome?

The species has been sequenced in the framework of the 1KB Fungal Genomes Project, which aims to increase knowledge of phylogenetic relationships and functional diversity among fungi. On-going research based on a meta-population genomics study in Fennoscandia using RAD sequencing will be facilitated by complete reference genome of Phellinidium ferrugineofuscum. Like many other members of the family Hymenochaetaceae, P. ferrugineofuscum is a primary colonizer, hence playing a major role in creating favorable conditions that will have positive effects on the colonization of the successional fungal species. Consequently, the genome of P. ferrugineofuscum will increase our knowledge of white rot biochemistry in primary colonizing and it will create new opportunities for comparative studies on wood degradation biochemistry with other Phellinus sensu lato species P. viticola and P. nigrolimitatus that are being sequenced.

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 Please contact the PI associated with unpublished 1KFG genomes for permission prior to the use of any data in publications.
