“…In addition to plant diversity, the local soil properties in the studied forest soils also control the EMF taxonomic community composition. Among these soil variables, soil nitrogen and it’s form such as the ammonium (NH 4 + ) and total nitrogen (TN) were the key regulators in our study, and this is in line with the results of previous studies displaying close relationship between soil NH 4 + and EMF community composition in forest soil systems ( Suz et al, 2017 ; Baeza-Guzmán et al, 2022 ). Different EMF taxa respond differently to the varying N availability.…”

“…This indicated the sensitivity and adaptability of EMF mycelium to shift their functional role depending on soil nutrients status and availability. A similar result was reported in a recent study conducted in high altitude regions with poor nutrients and harsh environment ( Baeza-Guzmán et al, 2022 ). The same study showed that the EMF communities developed abundant mycelium in order to acquire more nutrients for the host plant.…”

“…Each of the exploration types may represent a distinct foraging strategy under different soil and environmental conditions ( Lilleskov et al, 2011 ). Hence, exploring the patterns of EMF exploration types would highlight EMF responses to environmental changes, and changing EMF functional diversity across different forest ecosystems ( Rosinger et al, 2018 ; Baeza-Guzmán et al, 2022 ). Nevertheless, little is known about the environmental regulators of EMF functional traits under different forests within the subalpine climatic zone.…”

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.
