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.
