... one species was collected in Inner Mongolia, and most species came from Yunnan and Zhejiang. Moreover, the diversity of species collected in Yunnan was significantly higher than that in Zhejiang and Inner Mongolia (Figure 2). The number of species isolated from shoots of Poaceae is more than that from roots (Figure 3). ...

... species were uncovered from the roots of Poaceae grass in the New Jersey Pine Barrens of United States as fungal endophytes (Luo et al., 2014(Luo et al., , 2015b. Five strains belonging to Pseudophialophora eragrostis, Pseudophialophora schizachyrii, and an unidentified Pseudophialophora clade 1 (presumably novel species) were recovered from the roots of Poaceae grass in the Zhejiang and Yunnan provinces (Figures 2, 3), and an unidentified Pseudophialophora clade 1 was also recovered from the root of Cyperaceae host plant by meta-analysis (Figure 4). It indicated that Pseudophialophora species may be specifically colonized in the plant roots and not only in Poaceae plants but also in other monocotyledonous herbaceous plants with global distribution. ...

In sagebrush steppes of Western North America, dark septate endophytic fungi (DSEs) are typical components of the soil microbiota. To study the response of native plants to these fungi, a DSE was first isolated from the roots of the dominant shrub Artemisia tridentata. The isolate was a non-described species within the Darksidea or a closely relate...

Fomes fomentarius is a widespread, wood-rotting fungus of temperate, broadleaved forests. Although the fruiting bodies of F. fomentarius persist for multiple years, little is known about its associated microbiome or how these recalcitrant structures are ultimately decomposed. Here we used metagenomics and metatranscriptomics to analyse the microbial community associated with healthy living and decomposing F. fomentarius fruiting bodies to assess the functional potential of the fruiting body-associated microbiome and to determine the main players involved in fruiting body decomposition. F. fomentarius sequences in the metagenomes were replaced by bacterial sequences as the fruiting body decomposed. Most CAZymes expressed in decomposing fruiting bodies targeted components of the fungal cell wall with almost all chitin-targeting sequences, plus a high proportion of beta-glucan-targeting sequences, belonging to Arthropoda. We suggest that decomposing fruiting bodies of F. fomentarius represent a habitat rich in bacteria, while its decomposition is primarily driven by Arthropoda. Decomposing fruiting bodies thus represent a specific habitat supporting both microorganisms and microfauna.
... Organic-based fertilizers were most strongly associated with fungal family Chaetomiaceae, the majority of which are saprotrophs (decomposers) and some species are used to decompose plant biomass (reviewed in [69]). Family Magnaporthaceae was also strongly associated with organic fertilizers and this family contains species found in plant tissues including roots and have a nectrotroph lifestyle [70]. These taxa may contribute to the decomposition of greater organic residues occurring from manure and legume fertility sources. ...
Background: Soil microbiomes are critical to soil health and sustainable agriculture. Microbiome structures differ across agricultural soils that experience different management practices, such as tillage, fertilizers, and cover crops. Environmental factors, including those related to soil management, and microbiome-interactions alter these microbial communities. However, the full extent of these influences and relationships is not comprehensively understood. Here, we applied machine learning-based methods to identify prokaryotic and fungal assembly and distribution across various soil depths from fields under different agricultural practices.
Results: Fertility source was the most pronounced agricultural factor for microbial assembly, especially for fungal communities, and this impact lessened as soil depth increased. Furthermore, fertility source shaped co-occurrence patterns within the microbial community, leading to fertility source-sensitive modules dominated by fungi down to 30 cm soil depth. Tillage predominantly affected microbial communities in soil depths of 0-20 cm, and not only enhanced microorganism dispersal but also amplified stochastic processes, especially in the prokaryotic community. However, tillage potentially jeopardized interactions within the microbiome. In contrast to the fertility source and tillage, cover crops had a less pronounced effect on microbial communities, with no clear depth-dependent patterns; however, they still affect microbial co-occurrence patterns to some extent. Additionally, microorganisms at varying depths, specifically 0-20 cm for tillage and cover crops and 0-60 cm for fertility sources, were indicative of different agricultural practices.
Conclusions: Our result showed that the impact of agricultural practices on microbial communities is multifaceted, including the assembly process, interactions, and recruitment of specific microorganisms. We also demonstrated that machine learning models can overcome certain limitations of traditional methods, offering enhanced insights into the mechanisms underlying microbial assembly and distribution in agriculture soils.
... Hence, Magnaporthales contains five families Ceratosphaeriaceae, Magnaporthaceae, Ophioceraceae, Pseudohalonectriaceae, and Pyriculariaceae. Members of Magnaporthales are plant pathogens, endophytes, and saprobes, and most species have geographical, host, and tissue specificity (Feng et al. 2021). ...

Freshwater fungi comprises a highly diverse group of organisms occurring in freshwater habitats throughout the world. During a survey of freshwater fungi on submerged wood in streams and lakes, a wide range of sexual and asexual species were collected mainly from karst regions in China and Thailand. Phylogenetic inferences using partial gene regions of LSU, ITS, SSU, TEF1α, and RPB2 sequences revealed that most of these fungi belonged to Dothideomycetes and Sordariomycetes and a few were related to Eurotiomycetes. Based on the morphology and multi-gene phylogeny, we introduce four new genera, viz. Aquabispora, Neocirrenalia, Ocellisimilis and Uvarisporella, and 47 new species, viz. Acrodictys chishuiensis, A. effusa, A. pyriformis, Actinocladium aquaticum, Annulatascus tratensis, Aquabispora setosa, Aqualignicola setosa, Aquimassariosphaeria vermiformis, Ceratosphaeria flava, Chaetosphaeria polygonalis, Conlarium muriforme, Digitodesmium chishuiense, Ellisembia aquirostrata, Fuscosporella atrobrunnea, Halobyssothecium aquifusiforme, H. caohaiense, Hongkongmyces aquisetosus, Kirschsteiniothelia dushanensis, Monilochaetes alsophilae, Mycoenterolobium macrosporum, Myrmecridium splendidum, Neohelicascus griseoflavus, Neohelicomyces denticulatus, Neohelicosporium fluviatile, Neokalmusia aquibrunnea, Neomassariosphaeria aquimucosa, Neomyrmecridium naviculare, Neospadicoides biseptata, Ocellisimilis clavata, Ophioceras thailandense, Paragaeumannomyces aquaticus, Phialoturbella aquilunata, Pleurohelicosporium hyalinum, Pseudodactylaria denticulata, P. longidenticulata, P. uniseptata, Pseudohalonectria aurantiaca, Rhamphoriopsis aquimicrospora, Setoseptoria bambusae, Shrungabeeja fluviatilis, Sporidesmium tratense, S. versicolor, Sporoschisma atroviride, Stanjehughesia aquatica, Thysanorea amniculi, Uvarisporella aquatica and Xylolentia aseptata, with an illustrated account, discussion of their taxonomic placement and comparison with morphological similar taxa. Seven new combinations are introduced, viz. Aquabispora grandispora (≡ Boerlagiomyces grandisporus), A. websteri (≡ Boerlagiomyces websteri), Ceratosphaeria suthepensis (≡ Pseudohalonectria suthepensis), Gamsomyces aquaticus (≡ Pseudobactrodesmium aquaticum), G. malabaricus (≡ Gangliostilbe malabarica), Neocirrenalia nigrospora (≡ Cirrenalia nigrospora), and Rhamphoriopsis glauca (≡ Chloridium glaucum). Ten new geographical records are reported in China and Thailand and nine species are first reported from freshwater habitats. Reference specimens are provided for Diplocladiella scalaroides and Neocirrenalia nigrospora (≡ Cirrenalia nigrospora). Systematic placement of the previously introduced genera Actinocladium, Aqualignicola, and Diplocladiella is first elucidated based on the reference specimens and new collections. Species recollected from China and Thailand are also described and illustrated. The overall trees of freshwater Dothideomycetes and Sordariomycetes collected in this study are provided respectively and genera or family/order trees are constructed for selected taxa.
