“…A negative correlation between CTC, V%, Ca2+, Mg2+ and Acidipila-Silvibacterium was found in our results. In the study by Zhou et al , Acidipila-Silvibacterium presented a positive and negative presentation with K, P and N. Although in our study we did not evaluate P and N, the result for nutrient K corroborated this, indicating that this group of bacteria has a potential relationship with soil nutrients [ 75 ]. Regarding the negative correlation of CEC and V% with the genus Geothermomicrobium , a genus broadly found in soils, our study is the first that shows the correlation between this bacterium and the macro and micronutrients present in the soil of grapevines [ 76 ].…”

“…Changes in soil physicochemical properties caused by fire disturbances may lead to the disappearance of or a reduction in certain fungal species in the soil, and this affects the alpha diversity of soil fungi [51]. In some studies, MC, AP, AK and TN were found to correlate with changes in the alpha diversity of soil fungi [52,53]. In our study, the differences in the soil physical and chemical properties of the fire sites did not change the total number of soil fungal species in this study, which is in line with the results of others [51].…”

Fungi have important ecological functions in the soil of forests, where they decompose organic matter, provide plants with nutrients, increase plant water uptake, and improve plant resistance to adversity, disease, and disturbance. A forest fire presents a serious disturbance of the local ecosystem and can be considered an important component affecting the function of ecosystem biomes; however, the response of soil fungi to fire disturbance is largely unknown. To investigate the effects of fire disturbance on the community composition and diversity of soil fungi in a taiga forest, we collected soil from plots that had undergone a light, moderate, and heavy fire 10 years previously, with the inclusion of a fire-free control. The present soil fungi were characterized using Illumina MiSeq technology, and the sequences were analyzed to identify differences in the community composition and diversity in response to the changed soil physicochemical properties. The results showed that the Chao1 index, which characterizes the alpha diversity of the fungi, did not change significantly. In contrast, the Shannon index increased significantly (p < 0.05) and the Simpson index decreased significantly (p < 0.05) following a light or heavy fire disturbance compared to the control. The relative abundance of Basidiomycota was significantly higher in the soil of the fire sites than that in the control (p < 0.01), and the relative abundance of Ascomycota was significantly lower (p < 0.01). The results of principal coordinates analyses (PCoAs) showed that fire disturbance highly significantly affected the beta diversity of soil fungi (p < 0.001), while the results of canonical correlation analysis (CCA) indicated that the available nitrogen (AN), moisture content (MC), pH, available potassium (AK), and total nitrogen (TN) contents of the soil significantly affected the compositional structure and diversity of the soil fungal communities. The results of functional prediction showed that the majority of the detected soil fungi were symbiotrophs, followed by saprotrophs and saprotroph–symbiotrophs, with ectomycorrhiza being the dominant functional taxon. Fire disturbance significantly reduced the relative abundance of ectomycorrhiza (p < 0.05). This study illustrates that fire disturbance alters the structural composition, diversity, dominance, and relative abundance of the guilds of soil fungal communities in taiga forest, and strongly affected the beta diversity of soil fungi, with AN, MC, pH, AK, and TN being the most important factors affecting their community structure. The results may provide a useful reference for the restoration and rehabilitation of taiga forests after fire disturbance.

“…The mycorrhizal system is well known for its rich diversity of microorganisms within its associated microbiomes ( van der Heijden et al., 2015 ; Shi et al., 2023 ), which makes it an intriguing subject of research. The previous study of S. luteus -related biodiversity was mainly focused on the bacteria characterization ( Bending et al., 2002 ; Zhou et al., 2022 ), however, another layer of complexity contributed by mycoviruses infecting S. luteus remains unknown. Therefore, further research on mycoviruses associated with S. luteus is warranted.…”

Suillus luteus is a widespread edible ectomycorrhizal fungus that holds significant importance in both ecological and economic value. Mycoviruses are ubiquitous infectious agents hosted in different fungi, with some known to exert beneficial or detrimental effects on their hosts. However, mycoviruses hosted in ectomycorrhizal fungi remain poorly studied. To address this gap in knowledge, we employed next-generation sequencing (NGS) to investigate the virome of S. luteus. Using BLASTp analysis and phylogenetic tree construction, we identified 33 mycovirus species, with over half of them belonging to the phylum Lenarviricota, and 29 of these viruses were novel. These mycoviruses were further grouped into 11 lineages, with the discovery of a new negative-sense single-stranded RNA viral family in the order Bunyavirales. In addition, our findings suggest the occurrence of cross-species transmission (CST) between the fungus and ticks, shedding light on potential evolutionary events that have shaped the viral community in different hosts. This study is not only the first study to characterize mycoviruses in S. luteus but highlights the enormous diversity of mycoviruses and their implications for virus evolution.
