Mycorrhizal fungi are a type of fungi that develop multiple symbioses with different plants. Their role is central in the majority of the forests and ecosystems around the world, forming Mycorrhizal Networks, large groups of plants and fungi interconnected underground at the root level. Resources and signals are exchanged between plants and fungi in these networks, increasing the members’ chances of survival and their resistance to external stresses and disturbances. Further understanding of the behaviour and dynamics of arbuscular mycorrhizal fungi can help us interact with these networks and address the climate change crisis through indirect control of forests and ecosystems.
