Freshwater fungi are key players in the decomposition of leaf litter in rivers and streams because they can secrete exoenzymes that breakdown cellulose, hemicellulose, polysaccharides and lignin. The water temperature fluctuations influence fungal abundance, metabolic functions, growth, and survival. Genome sequencing is an important tool to reveal the microorganism adaptation to the environment. Therefore, we sequenced the genomes of saprobe freshwater hyphomycetes belonging to the Nectriaceae family (Sordariomycetes) and Helotiales order (Leotiomycetes) and compared their genome properties with fungal genomes of terrestrial habitats. The CAZy enzymes were predicted using run_dbCAN4 and adaptation to environment temperature, was predicted with the Thermoprot tool for cold and thermo-adaptation of their proteins. In Nectriaceae, the saprobe fungi, CAZy enzymes showed to be less abundant than in fungi with another lifestyle. The saprobes were equipped with higher numbers of cold-adapted and lower abundance of thermo-adapted enzymes in their genome. On the other hand, the helotialean freshwater fungi, have more CAZy enzymes than fungi with other lifestyle, and have higher thermo-adapted enzymes than soil-saprobes (3777) and plant-pathogens (3478) but less than mycorrhiza (4649), and endophytes (4358) fungi, respectively. All fungal genomes from Helotiales show to have the same average number of cold-adapted proteins. Our results show that there are divergences in adaptation of freshwater fungi to the environment depending on the taxonomic group studied. These divergences can be an important factor to predict more competitive fungi in their associated environment, their biotechnological potential, and also select target species for conservation goals.
