Project Abstract
Most plants have coevolved alongside soil fungi which form mycorrhizal symbioses. Mycorrhizal symbiosis regulates numerous ecosystem functions and services related to nitrogen, phosphorus and carbon cycling, including greenhouse gas production and mitigation, and maintenance of soil biodiversity. A critical feature of the symbiosis is their ability to form �common mycorrhizal networks� (CMNs), where the belowground network formed by the fungal mycelium interconnects individual plants. In the laboratory, CMNs have been shown to affect nutrient distribution, plant competition and transfer of signals in response to above-ground plant pests as well as other molecules. Yet, our understanding of the ubiquity and function of fungal networks in agri-ecosystems is poorly understood, especially under �real-world� conditions. In this proposal, we focus on gaining a better understanding of the extent and ubiquity of CMNs, and their role in regulating key ecosystem functions relevant to sustainable food production. We will focus on grazed permanent grassland systems because of their global extent, importance for agriculture and in providing numerous ecosystem services, and the urgent need for solutions to tackle grassland degradation. Moreover, most grassland plant species form mycorrhizal associations, and a range of management strategies are available to modify the extent and function of fungal networks. Our international collaborative network provides the expertise required to conduct manipulation experiments and field assessments together with cutting-edge isotopic and molecular methods to interrogate mycorrhizal fungal networks and their function. SOIL-HEAL will generate fundamental new knowledge and applied understanding of a critical component of soil biodiversity that regulates numerous ecosystem services
