Venturiales, an order from Dothideomycetes, comprises of a group found as plant and animal parasites or saprobes in plant debris and soil (Zhang et al., 2011; Shen et al., 2020), including in the Arctic (Semenova et al., 2016; Christiansen et al., 2017). The isolate P10P74 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 gas 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.
