“…In the tundra, where nutrient availability is restricted, most plants form symbioses with mycorrhizal fungi; plants provide fungi with photosynthesised carbon in exchange for enhanced nutrient and water uptake provided by the fungi (Gardes & Dahlberg, 1996). Different groups of mycorrhizal fungi vary in their impact on the ecosystem carbon (C) balance and response to environmental conditions (Girlanda et al, 2007;Vohn ık, 2020;Fall et al, 2022). In grasslands, the predominant type is arbuscular mycorrhiza (AM), since they associate with most forbs and graminoids (Smith & Read, 2008).…”

Summary Climate warming is severely affecting high‐latitude regions. In the Arctic tundra, it may lead to enhanced soil nutrient availability and interact with simultaneous changes in grazing pressure. It is presently unknown how these concurrently occurring global change drivers affect the root‐associated fungal communities, particularly mycorrhizal fungi, and whether changes coincide with shifts in plant mycorrhizal types. We investigated changes in root‐associated fungal communities and mycorrhizal types of the plant community in a 10‐yr factorial experiment with warming, fertilisation and grazing exclusion in a Finnish tundra grassland. The strongest determinant of the root‐associated fungal community was fertilisation, which consistently increased potential plant pathogen abundance and had contrasting effects on the different mycorrhizal fungal types, contingent on other treatments. Plant mycorrhizal types went through pronounced shifts, with warming favouring ecto‐ and ericoid mycorrhiza but not under fertilisation and grazing exclusion. Combination of all treatments resulted in dominance by arbuscular mycorrhizal plants. However, shifts in plant mycorrhizal types vs fungi were mostly but not always aligned in their magnitude and direction. Our results show that our ability to predict shifts in symbiotic and antagonistic fungal communities depend on simultaneous consideration of multiple global change factors that jointly alter plant and fungal communities.

Mycorrhizae are symbiotic associations between soil fungi belonging to diverse taxa and the roots of about % of all terrestrial plant species. The mutualistic nature of these symbioses is based on the nutritional exchanges between the partners. However, the benefits to the plant partner are not limited to an improved mineral nutrition because they also include a general increase in stress tolerance and health. Because of these benefits, mycorrhizae are of great interest in sustainable agriculture and forestry. In the past few years, the development of highthroughput molecular tools, in addition to the advancements in microscopy techniques, has allowed us to gain a deeper insight on the molecular mechanisms underlying the establishment and functioning of these symbioses. In this chapter, we focus on the use of proteomic tools to better understand the molecular bases of cell communication and the regulation of developmental and metabolic pathways in mycorrhizal associations.
