Mycorrhizal networks are underground systems formed by the symbiotic relationship between fungi and the roots of plants. These networks allow for the exchange of nutrients, water, and information between different plants, enhancing their growth and resilience. The fungi extend their hyphae, or thread-like structures, into the soil, connecting multiple plants and facilitating communication. These networks play a crucial role in ecosystems by promoting biodiversity and supporting plant health. They help plants share resources, such as carbon and nitrogen, and can even warn neighboring plants of potential threats, like pests or diseases, thereby improving their chances of survival.
