The exchange of nutrients between host plants and arbuscular mycorrhizal fungi is presumed to be the main benefit for the two symbiotic partners. In this review article, we outline the current concepts of nutrient exchanges within this symbiosis (mechanisms and regulation). First, we focus on phosphorus and nitrogen transfer from the fungal partner to the host plant and on the reciprocal transfer of carbon compounds, with a highlight on a possible interplay between nitrogen and phosphorus nutrition during arbuscular mycorrhizal symbiosis. We further discuss potential mechanisms of regulation of these nutrient exchanges linked to membrane dynamics. The review finally addresses the common mycorrhizal networks formed by arbuscular mycorrhizal fungi, which inter-connect plants from similar and/or different species. Then the best way to integrate this knowledge and the ensuing potential benefits of arbuscular mycorrhiza in a sustainable agriculture is discussed. This article is protected by copyright.
