Microbotryomycetes incertae sedis (former Slooffia tsugae) - isolate P6C30

The Microbotryomycetes are within the Basidiomycota and include plant and mycoparasites and anamorphic yeasts (Oberwinkler, 2017; Toome et al., 2012). Yeasts of these groups have been found in the Arctic and Antarctic (Turchetti et al., 2011; Perini et al., 2021). The isolate P6C30 has been isolated from the sediment of thermokarst ponds in Abisko, Sweden. Thermokarst ponds, which emerge from the thawing permafrost, can be hotspots for microbial production and become an important source of greenhouse gasses emissions (Abnizova et al., 2012). However, little is known about the fungal contribution in such water bodies when it comes to carbon degradation. The genome sequencing of fungal isolates from these environments aims to assess their functional potential, and to better understand the fungal contribution in the permafrost carbon feedback.
