Abstract
Arbuscular mycorrhizal (AM) fungi, as obligate biotrophs, rely for their growth and activity on carbon provided by their host plant and, in exchange, they improve the mineral nutrition of the plant, in particular the acquisition of phosphorus and to some extent of nitrogen and other minor nutrients. This nutrient exchange takes place across the symbiotic interfaces that are developed as the fungus colonizes the root system. In this chapter, we provide an overview of the biochemical and molecular mechanisms involved in nutrient transport processes in AM, with special emphasis on those underlying the bidirectional nutrient exchange between symbionts at the symbiotic interfaces.
