It is a dual-mycorrhizal tree associated with both arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) fungi. To understand how ECM communities associated with Sal roots are structured, we studied their diversity, composition, and root colonisation in four tropical forests along an elevation gradient (82 to 950 m a.s.l.). The ECM community was not found to be very diverse: we obtained 155 ECM operational taxonomic units (OTUs) belonging to 13 ECM genera in 8 families of Basidiomycota. The genus Tomentella was the most dominant, followed by Russula and Inocybe. Elevation explained 10.2% of variability in ECM composition, and significant effects of forest type, geographic position, soil temperature and moisture were confirmed. The forest at the highest elevation had ECM communities whose community structure was divergent from those at lower elevation. ECM root colonisation significantly decreased with increasing elevation and decreasing available P content. Whereas a low number of ECM species produced a high ECM colonisation of Shorea roots in low-elevation forests, a more diverse ECM community formed a low ECM colonization in high-elevation forests. The identified dominant species may be potentially used as inoculum for Sal forest restoration.</p>","PeriodicalId":18965,"journal":{"name":"Mycorrhiza","volume":"35 4","pages":"50"},"PeriodicalIF":3.8,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144822089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the influence of arbuscular mycorrhizal (AM) fungal consortia on microbial community dynamics across two stages of soil recovery - 2 years (2Y) and 15 years (15Y) post-disturbance - using a secondary succession forest (SSR) as a reference. We analyzed bacterial community composition via 16 S rRNA gene amplicon sequencing and evaluated key soil quality indicators. While inoculation with AM fungal consortia had minimal effects on most soil parameters, significant differences were observed between recovery stages. The 15Y recovery site exhibited improved soil structure, microbial activity, and aggregate stability compared to the 2Y site, highlighting the importance of long-term restoration. However, potential overlap in ecological roles among native microorganisms likely mitigates the impact of AMF inoculation. These findings suggest that AM fungal consortia alone may not drive immediate improvements in soil quality but can contribute to microbial interactions and recovery processes over time. This study highlights the complexity of soil restoration and emphasizes the need for strategies that integrate plant cover with microbial community development to enhance long-term ecosystem stability.

These interactions can impact plant health and ecosystem function, yet the role of these radial plants in mycorrhizal interactions and subsequent plant performance remains underexplored. Here we investigated the influence of hyphal exploration and interaction with neighbouring mycorrhizal plants, plants that are weakly mycorrhizal, and a lack of neighbouring plants on the performance of Plantago lanceolata, a mycotrophic perennial herb common to many European grasslands, using mesh cores and the manipulation of neighbouring plant communities. Allowing growth of hyphae beyond the mesh core increased carbon capture above-ground and release below-ground as root exudates and resulted in the greater accumulation of elements relevant to plant health in P. lanceolata. However, contrary to expectations, the presence of mycorrhizal, or weakly mycorrhizal neighbours as well as an absence of neighbours did not significantly alter the benefits of hyphal networks to P. lanceolata. Our findings demonstrate that enabling the development of a fungal network beyond the immediate host rhizosphere significantly influences plant leaf elemental stoichiometry, enhances plant carbon capture, and increases the amount of carbon they release via their roots as exudates.

Our results showed that, although ECM fungal richness and Shannon diversity were similar among spruce species at each site, their ECM fungal community composition differed. The differences in ECM fungal community composition between paired spruce species were not significant at the wettest site, but were significant at two dry sites, with the main difference observed between P. asperata and other spruce species (p < 0.05). The Mantel test indicated a weak positive correlation between ECM fungal community composition differences and the phylogenetic distance among host species.

The first step to confirm the existence of such networks is to assess the extent and nature of symbiont sharing in the mycelial community. To address this question, we incubated in-growth mesh bags under the native Ostrya carpinifolia and Quercus pubescens, and the non-native Pinus nigra, over two consecutive years. In Q. pubescens and P. nigra, but not in O. carpinifolia, mycelium production was significantly higher in the year with higher spring precipitation, indicating the influence of climatic conditions, but also the identity of the host tree. We observed a complex interaction between tree species and sampling year in structuring the composition and diversity of mycelial communities. Local environmental conditions contributed additionally and were responsible for 21.46% of the community variation between samples. Although ~ 70% of fungal operational taxonomic units were shared across the studied tree species, distinct community compositions emerged, emphasizing the role of host tree specificity. Q. pubescens exhibited greater stability in EcM richness between sampling years, whereas P. nigra showed lower EcM richness, likely due to limited availability of compatible fungi and reliance on introduced fungal partners. Additionally, differences in EcM fungal exploration strategies were observed. O. carpinifolia and Q. pubescens mainly hosted non-specific EcM fungi with short distance exploration types. In contrast, EcM fungi of P. nigra had higher spatial spread, and were predominantly conifer specific.

Therefore, this study explored the relationships among GRSP and SOC with climatic and edaphic factors along elevation gradients (666-3892 m) spanning diverse forest types in tropical rainforest, subtropical forest, and subalpine forest in Yunnan, Southwest China. Our findings revealed that AMF spore abundance declined, whereas AMF root colonization and GRSP concentrations increased with increasing elevation. GRSP showed a stronger positive correlation with AMF root colonization than with spore abundance, particularly in subtropical and subalpine forests where nutrient availability was higher. A significant positive relationship was observed between GRSP and SOC across all three forest sites, with the strongest association in subtropical forests.

Recent stable isotope analyses of fungal pelotons isolated from roots have advanced our understanding of this nutritional strategy; however, concerns remain regarding potential isotopic biases, particularly ¹⁵N depletion during lysis or extraction. To address these concerns, we focused on Gastrodia pubilabiata, a fully mycoheterotrophic orchid that associates with saprotrophic fungi. This species offers an ideal system to test whether peloton tissues reliably reflect fungal isotope signatures, as its mycorrhizal roots occasionally occur in direct contact with the fruiting bodies of its fungal partner. We measured δ¹³C and δ¹⁵N values in the aboveground tissues of G. pubilabiata, pelotons extracted from its roots, and fruiting bodies of the associated wood-decaying fungus Cyanotrama gypsea, along with neighboring autotrophic reference plants. The stable isotope analysis revealed that δ¹³C values were nearly identical between pelotons and fruiting bodies, while δ¹⁵N values were slightly higher in pelotons, indicating that peloton-derived isotopic data reliably reflect the fungal source. Moreover, the ¹³C and ¹⁵N enrichment observed in the orchid relative to the fungal fractions was broadly consistent with expected trophic-level fractionation, suggesting a predator-prey-like mode of nutrient transfer.

Although a shift from predominance of arbuscular mycorrhizal to ectomycorrhizal colonization with plant development has been demonstrated on other dual-mycorrhizal hosts, it is not known how mycorrhizal colonization shifts with plant age in Populus species. We performed a controlled growth experiment with natural field-sourced inocula to test for age-dependent shifts in fungal colonization rates and for host-specific patterns of colonization in two species of Populus (P. tremuloides and P. trichocarpa). We found that only P. trichocarpa displayed dual-mycorrhizal colonization, while P. tremuloides associated with ectomycorrhizal fungi, but not arbuscular mycorrhizal fungi. Both guilds of mycorrhizal fungi increased in abundance with plant age, while root endophytic fungal colonization decreased. Many of the early-colonizing endophytic fungi that we documented have strong saprotrophic capabilities, which may be an important trait for fast colonization. Dark septate endophytes were more abundant than either guild of mycorrhizal fungi, and are likely to be functionally important members of the Populus root fungal community.
