“…Ascomycota, the dominant phylum in our study, includes > 3000 species that are specialized on a saprobic lifestyle in freshwater habitats where they successfully grow and sporulate (Shearer et al 2007, Kirk et al 2008, Shearer and Raja 2010. In line with this, many of the most dominant orders in our study belonging to the phylum Ascomycota were those known to represent aquatic fungi, such as Eurotiales, Hypocreales, Pezizales, Diaporthales, Sordariales, Xylariales, Mucorales, Chaetothyriales, Helotiales, Saprolegniales, Peronosporales and Pleosporales (Shearer et al 2007, Shearer and Raja 2010, Embree and Indoh 1967, Chandrasiri et al 2021, Kohout et al 2012, Beakes and Sekimoto 2009, and could represent indwellers in the lakes. Aquatic Saprolegniales are widespread animal pathogens of salmonids, amphibians and crustaceans (Bruno et al 2011, Hussein and Hatai, 2002, Fregeneda-Grandes et al 2007).…”

“…In contrast, Agaricales, Polyporales, Boletales, Russulales, Mortierellales and Botryosphaeriales within the phylum Basidiomycota which were among the most abundant orders found in our lakes, is more likely to be an inactive community member. While there are some true aquatic Agaricales and Mortierellales (Frank et al 2010, Embree and Indoh 1967), this order typically comprises terrestrial fungi. Manymembers of Russulales, Cantharellales and Boletales are mycorrhizal fungi which depend on plant hosts to sustain growth (Halling 2001, Bonito et al 2013, Xu et al 2021, Floudas 2021).…”

Fungi are essential components in a wide range of ecosystems and while major efforts have been spent on disentangling the diversity and functional roles of fungi in terrestrial environments, our knowledge about aquatic fungi is lagging. To address this knowledge gap, we explored meta-genomes from 25 lakes from the arctic and boreal zone and one tropical reservoir with the aim of describing the community structure of fungi and fungi-like organisms (Oomycota). A second ob-jective was to identify possible environmental factors influencing the composition of the fungal communities. Our results show that the main fungal phyla and orders are the same across all the lakes despite the differences in geographic location and prevailing climate. Still, there was differ-ential distribution of more highly resolved taxa across the lakes that accordingly featured distinct communities, possibly caused by differential availability of carbon substrates in the lakes. A more detailed classification of sequences related to the pathogenic Oomycota genus Phytophthora clear-ly demonstrated that while technologies now exist for sequencing entire microbial communities in great detail, we are still severely limited by insufficient coverage of eukaryotic sequences and genomes in public databases.

Fungal evolution: diversity, taxonomy and phylogeny of the Fungi

2019

View full text Add to dashboard Cite

The fungal kingdom comprises a hyperdiverse clade of heterotrophic eukaryotes characterized by the presence of a chitinous cell wall, the loss of phagotrophic capabilities and cell organizations that range from completely unicellular monopolar organisms to highly complex syncitial filaments that may form macroscopic structures. Fungi emerged as a 'Third Kingdom', embracing organisms that were outside the classical dichotomy of animals versus vegetals. The taxonomy of this group has a turbulent history that is only now starting to be settled with the advent of genomics and phylogenomics. We here review the current status of the phylogeny and taxonomy of fungi, providing an overview of the main defined groups. Based on current knowledge, nine phylum-level clades can be defined: Opisthosporidia, Chytridiomycota, Neocallimastigomycota, Blastocladiomycota, Zoopagomycota, Mucoromycota, Glomeromycota, Basidiomycota and Ascomycota. For each group, we discuss their main traits and their diversity, focusing on the evolutionary relationships among the main fungal clades. We also explore the diversity and phylogeny of several groups of uncertain affinities and the main phylogenetic and taxonomical controversies and hypotheses in the field.

“…Originally, this fungal group was considered as a family of the Mucorales, named Mortierellaceae [13] containing two genera, Herpocladium [14] and Mortierella [15]. Subsequently, several genera were added to the family or segregated from the genus Mortierella , such as Dissophora , Haplosporangium [16], Azygozygum [17], Umbelopsis [18], Aquamortierella [19], Echinosporangium [20], Actinomortierella [21], Modicella and Gamsiella [22]. Echinosporangium is now regarded as a synonym of Lobosporangium [22].…”

Data Partitions, Bayesian Analysis and Phylogeny of the Zygomycetous Fungal Family Mortierellaceae, Inferred from Nuclear Ribosomal DNA Sequences

Although the fungal order Mortierellales constitutes one of the largest classical groups of Zygomycota, its phylogeny is poorly understood and no modern taxonomic revision is currently available. In the present study, 90 type and reference strains were used to infer a comprehensive phylogeny of Mortierellales from the sequence data of the complete ITS region and the LSU and SSU genes with a special attention to the monophyly of the genus Mortierella. Out of 15 alternative partitioning strategies compared on the basis of Bayes factors, the one with the highest number of partitions was found optimal (with mixture models yielding the best likelihood and tree length values), implying a higher complexity of evolutionary patterns in the ribosomal genes than generally recognized. Modeling the ITS1, 5.8S, and ITS2, loci separately improved model fit significantly as compared to treating all as one and the same partition. Further, within-partition mixture models suggests that not only the SSU, LSU and ITS regions evolve under qualitatively and/or quantitatively different constraints, but that significant heterogeneity can be found within these loci also. The phylogenetic analysis indicated that the genus Mortierella is paraphyletic with respect to the genera Dissophora, Gamsiella and Lobosporangium and the resulting phylogeny contradict previous, morphology-based sectional classification of Mortierella. Based on tree structure and phenotypic traits, we recognize 12 major clades, for which we attempt to summarize phenotypic similarities. M. longicollis is closely related to the outgroup taxon Rhizopus oryzae, suggesting that it belongs to the Mucorales. Our results demonstrate that traits used in previous classifications of the Mortierellales are highly homoplastic and that the Mortierellales is in a need of a reclassification, where new, phylogenetically informative phenotypic traits should be identified, with molecular phylogenies playing a decisive role.
