Sistotrema spB PMI390
Phylogenetic tree of Sistotrema and Clavulina species based on RPB2 genes (by Greg Bonito).
Within the framework of the JGI  CSP 'Metatranscriptomics of Forest Soil Ecosystems' project, we are aiming to explore the interaction of forest trees with communities of soil fungi, including ectomycorrhizal symbionts that dramatically affect bioenergy-relevant plant growth, and saprotrophic soil fungi impacting carbon sequestration in forests. We are sequencing the genome of the most abundant fungal species harvested from several long-term observatories to serve as the foundation for a reference database for analyzing metatranscriptomic profiling of soil fungi.

Sistotrema sp. PMI_390

The isolate PMI 390 whose genome was sequenced here is an environmental isolate cultured from a healthy Pinus taeda (loblolly pine) ectomycorrhiza collected in Duke Forest, NC, USA. Initially identified as a Clavulinaceae species, phylogenetic analysis of RPB2 indicated it is related to the Sistotrema clade B (see Figure). Sistotrema species are resupinate wood-rotting basidiomycetes belonging to the Hydnaceae (Cantharellales). They are often found in soil, moss, plant debris, and rotten wood as well as seedling pine roots and ectomycorrhizae. This species is being studied through the DOE Plant-Microbial Interfaces and NSF Dimensions of Biodiversity projects. 

Together with the genomes of Sistotrema muscicola OMC 1658 and Sistotrema sernanderi OMC 1753, this genome broadens the sampling of lineages of unknown wood decay mode in Cantharellales.
