Mycelial dynamics in arbuscular mycorrhizal fungi

mycolabadmin

This review examines the intricate underground networks formed by arbuscular mycorrhizal fungi, which partner with most land plants to help them absorb nutrients from soil. These fungal networks are far more complex and dynamic than previously recognized, expanding through the soil in coordinated wave-like patterns and responding flexibly to changing environmental conditions. The research highlights that viewing these fungal networks as a unified, responsive system rather than separate parts can help us better understand how they support plant growth and maintain healthy ecosystems.

Legume-specific recruitment of rhizobia by hyphae of arbuscular mycorrhizal fungi

mycolabadmin

Underground fungal networks connect different legume plants and act like sophisticated GPS systems for helpful bacteria. These fungi transport chemical signals (flavonoids) from plant roots along their hyphae, guiding specific types of nitrogen-fixing bacteria to their correct host plants. This discovery shows how fungi help bacteria find the right plants to form symbiotic partnerships, improving natural nitrogen fixation and potentially reducing the need for chemical fertilizers in agriculture.

The influence of mycorrhizal hyphal connections and neighbouring plants on Plantago lanceolata physiology and nutrient uptake

mycolabadmin

Fungi that live in soil form partnerships with plant roots and can extend underground networks connecting multiple plants. In this study, plants with access to expanded fungal networks captured more carbon through photosynthesis, accumulated more nutrients like phosphorus and zinc, and released more carbon into the soil. However, whether neighboring plants were present or what type they were did not significantly change these benefits, suggesting that soil exploration volume matters more than plant-to-plant connections through fungal networks.
