Why are AMF such effective colonizers? 🌱🍄
Arbuscular Mycorrhizal Fungi (AMF), including Glomus and related genera, have evolved a remarkable strategy for establishing symbiosis with plant roots.
From persistent spores and root-derived strigolactone signals to molecular recognition, controlled root penetration, arbuscule formation, and extensive extraradical hyphae, AMF effectively extend the plant’s root system into the surrounding soil.
Inside the root, the arbuscule acts as a nutrient-exchange interface, enabling carbon transfer from the plant while supporting the acquisition of phosphorus, nitrogen, sulfur, micronutrients and water by the plant.
Outside the root, the extensive fungal network explores soil beyond the normal root depletion zone—making AMF powerful partners for nutrient acquisition, plant establishment, soil health and stress resilience.
This sophisticated plant–fungus partnership explains why AMF are among the most promising biological tools for sustainable agriculture.
