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.

Unilacryma unispora MAFF 240146

Unilacryma unispora is a conifer-inhabiting jelly-fungus of the order Dacrymycetes with inconspicuous minute fruiting bodies developing on dead coniferous wood. It is widely distributed in the temperate areas of the Northern Hemisphere. As its name suggests, Unilacryma unispora is unique among Dacrymycetes for having basidia with one sterigmata only, while other Dacrymycetes have two-sterigmatic basidia.

Unilacryma unispora is among the earliest diverging extant wood decomposing fungi. Considering that all other studied Dacrymycetes are brown-rotters, Unilacryma unispora is also likely a brown-rot fungus; the genome will help to confirm this. In phylogenetic analyses Unilacryma is the sister to the rest of the class Dacrymycetes (Shirouzu et al. 2013), which, in turn, are the earliest group of wood rotters in Agaricomycotina (Nagy et al. 2016). Shirouzu et al. (2013) described a separate order, Unilacrymales, for this species. In light of its phylogenetic position, the genome of this species is of major significance in understanding the evolution of wood decomposition in Basidiomycetes as well as creating a stable classification for the class Dacrymycetes.

The genome strain MAFF 240146 originates from a sample collected on Pinus densiflora in Nagano, Japan (TNS-F-15731).
