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.

Perenniporia subacida (Peck) Donk

The genus Perenniporia (order Polyporales) is most likely polyphyletic, with ca. 90 species across eight clades, fruiting on dead and living hardwood and conifers, causing white rots. The species (Group) Perenniporia subacida produces perennial effused tough sporocarps with a whitish to ivory margin, soft and up to 2-mm wide. Widely distributed in forest regions of Asia and North America, in Europe it is mainly a boreal eastern species where it usually grows on spruce (Picea abies), but has also been found on Larix and Pinus, with occasional records on hardwood (Populus and Prunus).

The strain PersubVin-SM18 was isolated from a sporocarp of Perenniporia subacida fruiting on dead spruce, sampled in Vinterbro (Viken), Norway.

Why sequence the genome?

Perenniporia subacida was traditionally accepted in Perenniporia, but the species did not appear to belong to Perenniporia based on the unbranched skeletal hyphae and ellipsoid and non-truncate basidiospores. Some studies have found that P. subacida is monophyletic and distinct from Perenniporia sensu stricto. The genome will be included in a large comparative genomics study of Polyporales.

Researchers who wish to publish analyses using data from unpublished CSP genomes are respectfully required to contact the PI and JGI to avoid potential conflicts on data use and coordinate other publications with the CSP master paper(s).
