Understanding how arbuscular mycorrhizal (AM) symbioses establish and function is one of the most important current challenges in microbial ecology. In AM symbiosis, the fungal symbiont and the plant partner benefit from each other in a number of ways. Indeed, availability, uptake and exchange of nutrients in biotrophic interactions will drive plant growth and modulate biomass allocation that are central to plant yield. Understanding mechanisms underlying nitrogen and phosphorus use efficiency by AM plants and carbon allocation in a context of mutualistic biotrophic interactions is critical for plant management. However, the establishment and the functioning of the plant-fungal interface as well as the local adaptation of the fungal mycelium rely on complex and highly coordinated regulations of plant and fungal gene expression that are not well understood. Here, we focus in particular on key players involved in the nutritional exchanges between the mycorrhizal plant and the associated AM fungi, and useful for developing future engineering of new agro-ecological systems.
