“…The most abundant class of fungi in the chernevaya taiga soils were Mortierellomycetes, comprising only the Mortierella genus, followed by Agaricomycetes and Globeromycetes (Rayko et al 2021). The saprotrophic Mortierella species are also characteristic of the soils of the middle taiga zone in West Siberia (Filippova and Bulyonkova 2017).…”

Chernevaya taiga in Western Siberia, Russia, is a special environment with fertile soil, extraordinarily high herbaceous plant sizes, and incredibly quick rates of plant residues breakdown. We postulated that a unique rhizospheric fungal community would be created when growing crops on chernevaya soil, which has never been used for agriculture. These may be the source for the novel effective biostimulator and biocontrol fungal agents for modern agriculture. In this study, we analyzed the fungal communities in the rhizosphere of spring wheat and radish cultivated in greenhouse experiments on chernevaya and control soils using high-throughput ITS sequencing.Additionally reprehensive fungal strains were isolated and examined for the stimulation of wheat seedlings growth.The research shows that Ascomycota and Mortierellomycota were the most abundant phyla in the rhizospheric fungal community, mainly composed of Mortierella species. The control soils were abundant in Mucoromycota, represented mostly by Mucor and Umbelopsis. Potentially plant-pathogenic fungi Fusarium and Oidiodendron were found only in the rhizosphere of crops grown in the control soil. Whereas plants grown on chernevaya soil have a wide variety of possible biocontrol fungi. Novel fungal isolates demonstrated stimulating effect on the growth and biomass accumulation of wheat seedlings. The findings of the study imply that the creation of biorational products for crop growth and protection may depend on the taxonomic composition analysis of the rhizospheric mycobiota of the crops growing on the soil with the unique characteristics.

“…After breaking down these results to the species level, all of the Mortierellomycetes abundance was comprised of only 4 Mortierella species, which demonstrates the domination of a single genus across all of the fungal communities. It was followed by yeast Solicoccozyma (Tremellomycetes) and mushroom-forming Inocybe (Agaricomycetes) species, which is typical for boreal forests [25].…”

The Chernevaya taiga of Western Siberia is a unique and complex ecosystem, distinguished by the unusually large sizes of herbaceous plants, the reasons for which are poorly understood. Here, we explored the fungal diversity of the Chernevaya taiga soils in the Tomsk regions of Western Siberia in comparison with other soil types. The soil biomes of Chernevaya taiga and the control regions were investigated using Illumina ITS rRNA sequencing, and taxonomic analysis revealed a predominance of fungal phyla in the different soils. These results demonstrate that the fungi of the Chernevaya taiga regions have a higher species diversity (Faith’s PD) vs. the control soils, and the diversity is due more to the sampling sites rather than to the seasons (Bray-Curtis distance). We studied most of the differentially abundant taxa among the soil types, and we annotated the taxa with their ecological guilds and trophic types. Some of the abundant fungal taxa in the summer- and fall-Chernevaya taiga samples belong to the phylum Glomeromycota—arbuscular mycorrhizal symbiotrophs, which are known to establish symbiotic relationships and enhance plant growth. Additionally, several OTUs were assigned to novel genera in the Glomeraceae and Claroideoglomeraceae families. Our findings add a potential explanation of the high productivity and plant gigantism in Chernevaya taiga and expand our knowledge of fungal biodiversity.

“…In forest ecosystems, biological diversity is caused by the vital activity of many organisms, including macromycetes [14,15,16]. They are widespread in nature and are a permanent component of biogeocenoses [17,18]. As heterotrophic organisms, they take an active part in the biological cycle of substances and energy [19,20] Currently, the main commonly accepted characteristics of biodiversity are species composition, taxonomic structure and spatial organization.…”

The study and conservation of biodiversity is one of the global problems of modern biology, since currently in many regions of the planet there is a decrease in the species composition of various organisms, including fungi. The obtained data make a significant contribution to the knowledge of the diversity of macromycetes of oak forests in the middle reaches of the Ural River, information about which is still insufficient and fragmented on the territory of Kazakhstan.The article presents data on the biodiversity of mycobiota of the oak forests of the Ural River valley, growing not only in the floodplain of the river, but also in beams, that is, the ravine forests flowing into the central floodplain. We have registered 31 species belonging to 23 genera, 17 families and five orders. The leading families are Polyporaceae, Boletaceae, Russulaceae, Amanitaceae. As a result of our research, it has been found that the mycological composition in ravine oak forests is richer than in floodplain oak forests. The richness of the species composition of macromycetes appears to have been influenced by well-defined associations in ravine oak forests (22 associations), represented by forest boreal tree-shrub species absent in floodplain oak forests, as well as favorable microclimatic conditions, relief, soil cover and various ecotopes that are not observed in floodplain oak forests (16 associations).Ecological-trophic analysis showed the predominance of mycorrhizal (45.1%) and xylotrophs (41.9%) over humus saprotrophs (12.9%). The considered taxonomic composition of macromycetes of the studied area is collected, identified and presented for the first time for this region.
