“…Although these records could, in principle, derive from soil residues on roots, we did clean the roots to the best of our abilities (see Materials and Methods). Other studies have shown hyphal colonization of non‐AM plants with no associated benefit to the plants (Cosme et al ., 2018; Wang et al ., 2021, 2022), and potentially this could be the case here, too. Nevertheless, the occurrences detected highlight the importance of further exploring the diversity of AM fungi in plant species otherwise considered non‐AM.…”

“…Taken at face value, higher frequencies of AM fungi at higher elevations might suggest a higher need for beneficial AM fungal symbioses in a more stressful environment (Menge et al ., 1978; Abrego et al ., 2020a,b). Yet, we stress that many AM fungal–plant associations may not be symbiotic at all (Cosme et al ., 2018; Wang et al ., 2022), and that further studies thereby are needed to determine the actual nature of the relationship. By comparison, the species richness of AM fungi differed among plant species, whereas the community composition of AM fungi proved to be jointly shaped by plant species and elevation.…”

“…Given the nature of our data, and given prior demonstrations of nonmutualistic colonization of nonhost plant roots by AM fungi (e.g. Cosme et al, 2018;Wang et al, 2021Wang et al, , 2022, we explicitly avoid using the presence of DNA of AM fungi (Glomeromycotina) as evidence for the existence of arbuscular mycorrhizal structures or symbiotic relations between plants and AM fungi.…”

“…Arbuscular mycorrhizal (AM) fungi are important root symbionts found in the majority of terrestrial plant roots (van der Heijden et al ., 2015). Arbuscular mycorrhizal fungi can have significant impacts on plant fitness (Klironomos et al ., 2000), plant community composition (Hartnett & Wilson, 1999; van der Heijden et al ., 2008) and ecosystem functioning (van der Heijden et al ., 2015) – although in other cases, AM fungi have been found to colonize plant roots with few benefits for the plant (Cosme et al ., 2018; Wang et al ., 2021, 2022). Since the advent of modern sequencing techniques, the global diversity patterns of AM fungi have become increasingly well understood (Kivlin et al ., 2011; Davison et al ., 2015, 2018).…”

Knowledge about the distribution and local diversity patterns of arbuscular mycorrhizal (AM) fungi are limited for extreme environments such as the Arctic, where most studies have focused on spore morphology or root colonization. We here studied the joint effects of plant species identity and elevation on AM fungal distribution and diversity.We sampled roots of 19 plant species in 18 locations in Northeast Greenland, using next generation sequencing to identify AM fungi. We studied the joint effect of plant species, elevation and selected abiotic conditions on AM fungal presence, richness and composition.We identified 29 AM fungal virtual taxa (VT), of which six represent putatively new VT. Arbuscular mycorrhizal fungal presence increased with elevation, and as vegetation cover and the active soil layer decreased. Arbuscular mycorrhizal fungal composition was shaped jointly by elevation and plant species identity.We demonstrate that the Arctic harbours a relatively species-rich and nonrandomly distributed diversity of AM fungi. Given the high diversity and general lack of knowledge exposed herein, we encourage further research into the diversity, drivers and functional role of AM fungi in the Arctic. Such insight is urgently needed for an area with some of the globally highest rates of climate change.

“…However, morphological identification such as AM arbuscules and EM Hartig net needs to be found on the same root to confirm the dual-colonization. The interaction between roots and fungi is not limited to symbiosis; hyphae can access additional roots without forming classical mycorrhizal morphology (Wang et al 2021). This interaction can serve as a relay or hub to create well distributed mycorrhizal networks in the forest.…”

Mechanisms of host-microbe interactions and their direct impact on both parties have been extensively researched, however, much less is known on the effect of these interactions on the ecology of the host-community. Here we investigate tree-fungi mycorrhizal interactions, focusing on mycorrhizal-meditated resource sharing among trees, while examining the dynamics between specialist and generalist fungi and their implications on the forest ecology. Using genetic meta-barcoding, we identified the fungal community colonizing different trees in a mixed forest, and generated an extensive mapping connecting fungal sequences to their tree hosts. The mycorrhizal fungal community diverged between ectomycorrhizal and arbuscular host trees, but, unexpectedly, multiple ectomycorrhizal species colonized roots of non-ectomycorrhizal host trees. We complemented these findings by a novel computational framework, modeling competition between generalist and specialist mycorrhizal fungi, accounting for fungal-mediated resource sharing among neighboring trees. The analysis of the model revealed that generalist mycorrhizal networks may affect the entire tree community, and contribute to the maintenance of forest diversity in the long run. Furthermore, higher initial spatial mixing of trees can promote the evolution of generalist mycorrhizal species. These novel belowground interactions among trees and fungi may significantly impact forest biodiversity.
