Sporocarp-associated fungal co-occurrence networks in a corn field revealed by long-read high-throughput sequencing

Soil Ecology Letters, Journal Year: 2024, Volume and Issue: 6(4)

Published: June 6, 2024

In forests, fungal sporocarps house the diverse fungicolous fungi; however, relationships of and associated communities are rarely explored in agroecosystems. a corn field near Gongzhuling City, Jilin Province, China, we found an epigeous sporocarp with agaricoid morphology that could grow next to living plants. Using PacBio metabarcoding combined updated bioinformatic pipeline, surveyed community profile along its cap, rhizomorph hyphosphere soil at much-improved taxonomic resolution. We identified sporocarp, high probability, as Agrocybe dura, this mushroom was significantly negatively correlated Trichoderma hamatum T. harzianum co-occurrence network. Fungal diversity habitat higher than cap habitats. Consistent pattern diversity, node number, edge network diameter average degree were other However, both negative positive cohesion Moreover, z-c plot A. dura only hub, linking multiple species. The results give us glimpse ecological relevance saprobic mushrooms across extensive northeastern black region China. Our findings will aid assessment forecasting hotspots their fertility 'Golden Corn Belt' northeast

Global diversity and biogeography of Lyophyllum inferred from amplicon datasets

Frontiers in Ecology and Evolution, Journal Year: 2024, Volume and Issue: 12

Published: June 18, 2024

Lyophyllum consists of rare edible and medicinal mushrooms. Considering this group’s economic ecological significance, understanding its biodiversity could be strategically important. Our analysis involved an extensive examination publicly available ITS sequences from NCBI-GenBank fungal amplicon sequencing data obtained NCBI-SRA. At a 98% sequence similarity level, we deliminated 88 OTUs, 49 which were not categorized as ‘known species’. The diversity is predominantly concentrated in the Northern Hemisphere tends to display endemic distribution, Europe particularly notable for high . Given escalating volume produced by sequencing, employing dataset can facilitate accurate survey species taxonomy. By using datasets, fieldwork time research funding taxonomists saved, thereby significantly advancing progress entire field research.

Drivers of wood‐inhabiting fungal diversity in European and Oriental beech forests

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(7)

Published: July 1, 2024

Abstract The hyperdiverse wood‐inhabiting fungi play a crucial role in the global carbon cycle, but often are threatened by deadwood removal, particularly temperate forests dominated European beech ( Fagus sylvatica ) and Oriental orientalis ). To study impact of abiotic drivers, factors, forest management biogeographical patterns both species on fungal composition diversity, we collected 215 deadwood‐drilling samples 18 from France to Armenia identified meta‐barcoding. In our analyses, distinguished driven rare, common, dominant using Hill numbers. Despite broad overlap species, with focus rare was determined type, diameter, precipitation, temperature, status decreasing order. Shifting common only climate variables type remained. richness within objects increased significantly decay stage. Gamma diversity higher than forests. We revealed highest gamma for old‐growth when focusing species. Our results implicate that retention efforts, critical process, should be distributed across precipitation temperature gradients Strategies additionally different diameters conservation

Host preference explains the high endemism of ectomycorrhizal fungi in a dipterocarp rainforest

Molecular Ecology, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 18, 2024

Abstract Ectomycorrhizal (ECM) fungi are important tree symbionts within forests. The biogeography of ECM remains to be investigated because it is challenging observe and identify species. Because most plant taxa have a Holarctic distribution, difficult evaluate the extent which host preference restricts global distribution fungi. To address this issue, we aimed assess whether enhances endemism that inhabit dipterocarp rainforests. Highly similar sequences 175 operational taxonomic units (OTUs) for were obtained from Lambir Hill's National Park, Sarawak, Malaysia, searched in nucleotide sequence database. Using two‐step binomial model, probability presence query OTUs registration rate barcode each country simultaneously estimated. results revealed respective countries increased with increasing species richness Dipterocarpaceae decreasing geographical distance study site (i.e. Lambir). Furthermore, shown endemic Malaysia neighbouring countries. These findings suggest not only dispersal limitation but also responsible high Moreover, likely determines areas where potentially expand creates distance–decay patterns suitable habitats. Although has received less attention than limitation, our support profound influence on

Variability in the dual mycorrhizal associations of tea tree, Melaleuca alternifolia

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 18, 2024

Background & aims. Tea tree (Melaleuca alternifolia) is an economically important crop plant with a limited natural distribution in eastern Australia. Coastal and upland tea ecotypes have been identified based on unique shoot root traits. Dual mycorrhization, the ability of plants to associate both arbuscular mycorrhizal (AM) ectomycorrhizal (ECM) fungi, particularly frequent among Australian Myrtaceae, including Melaleuca species. However, type currently unknown. Methods. We investigated associations three coastal two populations using ITS2 metabarcoding anatomical observations. Results. Our results revealed that dual showing variability symbioses populations. found ECM percentage colonisation was significantly lower compared populations, despite exhibiting higher levels fungal richness. In contrast, we showed moderate evidence AM richness than ecotypes, yet comparable were observed between ecotypes. Mycorrhizal community composition also differed plants. Conclusions. study provides dual-mycorrhizal species can host fungi simultaneously within individual findings suggest environmental factors sites, soil drainage nitrogen availability, affect traits native
