Fungi play major roles in ecosystem processes, but the determinants of fungal diversity and biogeographic patterns remain poorly understood. Using DNA metabarcoding data from hundreds globally distributed soil samples, we demonstrate that richness is decoupled plant diversity. The plant-to-fungus ratio declines exponentially toward poles. Climatic factors, followed by edaphic spatial variables, constitute best predictors community composition at global scale. show similar latitudinal...
Zygomycete fungi were classified as a single phylum, Zygomycota, based on sexual reproduction by zygospores, frequent asexual sporangia, absence of multicellular sporocarps, and production coenocytic hyphae, all with some exceptions. Molecular phylogenies one or few genes did not support the monophyly however, phylum was subsequently abandoned. Here we present phylogenetic analyses genome-scale data set for 46 taxa, including 25 zygomycetes 192 proteins, demonstrate that comprise two major...
We present a 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum Fungi. This analysis is most taxonomically complete to date with species sampled from all 15 currently circumscribed classes. A number superclass-level nodes that have previously evaded resolution and were unnamed in classifications Fungi are resolved for first time. Based on 6-gene we conducted phylogenetic informativeness 6 genes series ancestral character state reconstructions focused...
Mycorrhizal fungi are mutualists that play crucial roles in nutrient acquisition terrestrial ecosystems. symbioses arose repeatedly across multiple lineages of Mucoromycotina, Ascomycota, and Basidiomycota. Considerable variation exists the capacity mycorrhizal to acquire carbon from soil organic matter. Here, we present a combined analysis 135 fungal genomes 73 saprotrophic, endophytic pathogenic species, 62 including 29 new genomes. This study samples ecologically dominant guilds for which...
Bacterial and fungal communities associated with plant roots are central to the host health, survival growth. However, a robust understanding of root-microbiome factors that drive microbial community structure have remained elusive, especially in mature perennial plants from natural settings. Here, we investigated relationships bacterial rhizosphere root endosphere riparian tree species Populus deltoides, influence soil parameters, environmental properties (host phenotype aboveground...
Microbial communities in plant roots provide critical links between above- and belowground processes terrestrial ecosystems. Variation root has been attributed to host effects microbial preferences, as well factors pertaining soil conditions, biogeography the presence of viable propagules. To address hypotheses regarding influence on fungal bacterial communities, we designed a trap-plant bioassay experiment. Replicate Populus, Quercus Pinus plants were grown three soils originating from...
Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates morphological evolution accompany the transition to truffle form, closely related remain unknown for most lineages. This is case quintessential genus Tuber, which includes species with socio-economic importance and esteemed culinary attributes. Ecologically, Tuber spp. form obligate mycorrhizal symbioses diverse plant hosts including pines, oaks, poplars,...
Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns conservation needs of fungi have been little explored. Here, we examined endemicity patterns, global change vulnerability priority areas for functional groups soil based on six surveys using a high-resolution, long-read metabarcoding approach. We found that all most peaks in tropical habitats, including Amazonia, Yucatan, West-Central...
Endosymbiosis of bacteria by eukaryotes is a defining feature cellular evolution. In addition to well-known bacterial origins for mitochondria and chloroplasts, multiple endosymbiosis are known within the cells diverse animals, plants fungi. Early-diverging lineages terrestrial fungi harbor endosymbiotic belonging Burkholderiaceae. We sequenced metagenome soil-inhabiting fungus Mortierella elongata assembled complete circular chromosome its endosymbiont, Mycoavidus cysteinexigens, which we...
Novel species of fungi described in this study include those from various countries as follows: Australia , Austroboletus asper on soil, Cylindromonium alloxyli leaves Alloxylon pinnatum, Davidhawksworthia quintiniae Quintinia sieberi, Exophiala prostantherae Prostanthera sp., Lactifluus lactiglaucus Linteromyces (incl. gen. nov.) sieberi Lophotrichus medusoides stem tissue Citrus garrawayi Mycena pulchra Neocalonectria tristaniopsidis nov.)and Xyladictyochaeta Tristaniopsis collina,...
Knowledge of the factors controlling diverse chemical emissions common environmental bacteria and fungi is crucial because they are important signal molecules for these microbes that also could influence humans. We show here not only a high diversity mVOCs but their abundance can differ greatly in different contexts. Microbial volatiles exhibit dynamic changes across microbial growth phases, resulting variance composition emission rate species-specific generic mVOCs. In vitro experiments...
One of the most crucial steps in high-throughput sequence-based microbiome studies is taxonomic assignment sequences belonging to operational units (OTUs). Without classification, functional and biological information microbial communities cannot be inferred or interpreted. The internal transcribed spacer (ITS) region ribosomal DNA conventional marker for fungal community studies. While bioinformatics pipelines that cluster reads into OTUs have received much attention literature, less has...
Summary Endogonales (Mucoromycotina), composed of Endogonaceae and Densosporaceae, is the only known non‐Dikarya order with ectomycorrhizal members. They also form mycorrhizal‐like association some nonspermatophyte plants. It has been recently proposed that were among earliest mycorrhizal partners land remains unknown whether possess genomes mycorrhizal‐lifestyle signatures originated around same time as plants did. We sampled sporocarp tissue from four collections performed shotgun genome...
Mutualistic interactions between free-living algae and fungi are widespread in nature hypothesized to have facilitated the evolution of land plants lichens. In all known algal-fungal mutualisms, including lichens, algal cells remain external fungal cells. Here, we report on an interaction which Nannochloropsis oceanica become internalized within hyphae fungus Mortierella elongata. This apparent symbiosis begins with close physical contact nutrient exchange, carbon nitrogen transfer as...
Viruses are key drivers of evolution and ecosystem function increasingly recognized as symbionts fungi. Fungi in early-diverging lineages widespread, ecologically important, comprise the majority phylogenetic diversity kingdom. infecting fungi have been almost entirely unstudied. In this study, we screened for viruses by two alternative approaches: a classic culture-based method transcriptome-mining. The results our large-scale survey demonstrate that higher infection rates than previously...
How the multiple facets of soil fungal diversity vary worldwide remains virtually unknown, hindering management this essential species-rich group. By sequencing high-resolution DNA markers in over 4000 topsoil samples from natural and human-altered ecosystems across all continents, we illustrate distributions drivers different levels taxonomic phylogenetic fungi their ecological groups. We show impact precipitation temperature interactions on local species richness (alpha diversity)...
Abstract Background The colonization of land and the diversification terrestrial plants is intimately linked to evolutionary history their symbiotic fungal partners. Extant representatives these lineages include mutualistic plant symbionts, arbuscular mycorrhizal (AM) fungi in Glomeromycota fine root endophytes Endogonales (Mucoromycota), as well with saprotrophic, pathogenic endophytic lifestyles. These groups separate into three monophyletic but relationships remain enigmatic confounding...
Although microalgal biofuels have potential advantages over conventional fossil fuels, high production costs limit their application in the market. We developed bio-flocculation and incubation methods for marine alga, Nannochloropsis oceanica CCMP1779, oleaginous fungus, Mortierella elongata AG77, resulting increased oil productivity. By growing separately then combining cells, M. mycelium could efficiently capture N. due to an intricate cellular interaction between two species leading...
