Dothideomycetes are a large group of fungi that comprises about 19000 species (Wijayawardene, et al., 2017). These are ubiquitous fungi which can occupy different ecological niches, such as plant-pathogens, endophytes, mycorrhizal symbionts, and saprobes (Haridas et al., 2020). Dothideomycetes have been identified in extreme, cold environments (Onofri et al 2008), and have been found to be dominant in the Antarctic permafrost (Chen et al., 2017; Goordial et al., 2016). The isolate P12C66 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.
