“…Under the influence of this symbiotic microbial effect, the abundance of Ectomycorrhizal fungi increased significantly with the increase in radiation intensity. Because Ectomycorrhizal fungi form a biofilm on the root surface, this biofilm not only helps plants resist the invasion of pathogens, toxins, and drought ( Peter et al, 2016 ; Vincent and Declerck, 2021 ; Zheng and Song, 2022 ) but also promotes soil carbon sequestration by sequestering as microbial residues in the soil for a long period of time because of the difficulty of decomposition of its constituents ( Liang et al, 2017 ; Liang, 2020 ; Song et al, 2023 ). Moreover, Rhizobiales can also exchange nutrients with plants and have the ability to promote soil carbon sequestration ( Song et al, 2020 ).…”

As the environmental nuclear radiation pollution caused by nuclear-contaminated water discharge and other factors intensifies, more plant–microorganism–soil systems will be under long-term low-dose ionizing radiation (LLR). However, the regulatory mechanisms of the plant–microorganism–soil system under LLR are still unclear. In this study, we study a system that has been stably exposed to low-dose ionizing radiation for 10 years and investigate the response of the plant–microorganism–soil system to LLR based on the decay of the absorbed dose rate with distance. The results show that LLR affects the carbon and nitrogen migration process between plant–microorganism–soil through the “symbiotic microbial effect.” The increase in the intensity of ionizing radiation led to a significant increase in the relative abundance of symbiotic fungi, such as Ectomycorrhizal fungi and Rhizobiales, which is accompanied by a significant increase in soil lignin peroxidase (LiP) activity, the C/N ratio, and C%. Meanwhile, enhanced radiation intensity causes adaptive changes in the plant functional traits. This study demonstrates that the “symbiotic microbial effect” of plant–microorganism–soil systems is an important process in terrestrial ecosystems in response to LLR.

“…When natural ecosystems are replaced by human developments, the original soil and belowground biodiversity are signi cantly altered (Rusterholz et al, 2020). Poor agricultural practices such as excessive use of fertilizers and pesticides change these networks (Vincent & Declerck, 2021). Chemical pollution from farms severely affects ECM (Arnolds, 1991).…”

Ectomycorrhizae (ECM) are important symbionts for multiple host plants. This study used morphology and DNA metabarcoding to identify ECM in Dipterocarpaceae, the dominant tree family of Southeast Asian forests. ECM fruiting bodies were first visually documented and identified across five urban parks in Singapore. Under host Dipterocarp Hopea odorata trees, 50 soil and root samples were collected. This was done together with another 50 root samples taken from ten species of host Dipterocarp seedlings at the Singapore Botanic Gardens’ Plant Resource Centre nursery. Eight genera of ECM were found in parks, one was identified to species level and three genera were only found from fungal Amplicon Sequence Variants (ASVs) using DNA metabarcoding. Although the nursery had more Dipterocarp species, only four genera of ECM were present. ECM communities differed slightly across host species, but not host genera. Tomentella spp. were the most common ECM found in parks and Dipterocarp seedlings.

“…In forest ecology, ectomycorrhizal fungi (EMF) are an interface between the soil matrix and the host tree species. They often regulate the carbon and nutrients balance ( Lindahl and Tunlid, 2015 ; Lilleskov et al, 2019 ), and therefore are of significant importance in network building and maintaining the health and stability of the forest ecosystem ( Nash et al, 2020 ; Vincent and Declerck, 2021 ). In turn, the various biotic (plants and other organisms) and abiotic factors (e.g., the soil pH and niche specific microclimatic conditions) within the forest ecosystem affect the dynamics of EMF communities ( Roy et al, 2013 ; Pei et al, 2016 ; Glassman et al, 2017 ).…”

The symbiotic relationship between ectomycorrhizal fungi (EMF) and the roots of host plants is significantly important in regulating the health and stability of ecosystems, especially of those such as the climate warming affected subalpine forest ecosystems. Therefore, from the coniferous forest systems located in the Southern Qinghai-Tibetan Plateau, root tips from three forest tree species: Pinus wallichiana, Abies spectabilis and Picea spinulosa, were collected to look for the local causes of EMF community composition and diversity patterns. The EMF colonization rate, diversity and taxonomic community structure were determined by morphotyping and sanger sequencing of the fungal ITS gene from the root tip samples. Soil exploration types were identified based on the morphologies of the ectomycorrhizas, coupled with soil properties analysis and plant diversity survey. Contrasting patterns of EMF community and functional diversity were found across the studied three forests types dominated by different coniferous tree species. In terms of associations between soil and EMF properties, the total phosphorus (TP) and nitrate (NO3−) contents in soil negatively correlated with the colonization rate and the Shannon diversity index of EMF in contrast to the positive relationship between TP and EMF richness. The soil total nitrogen (TN), ammonium (NH4+) and plant diversity together caused 57.6% of the total variations in the EMF taxonomic community structure at the three investigated forest systems. Whereas based on the soil exploration types alone, NH4+ and TN explained 74.2% of variance in the EMF community structures. Overall, the findings of this study leverage our understanding of EMF dynamics and local influencing factors in coniferous forests dominated by different tree species within the subalpine climatic zone.
