Metabolism and interaction of C and N in the arbuscular mycorrhizal symbiosis
The arbuscular mycorrhiza (AM) is the symbiont formed by the host plant and the arbuscular mycorrhizal fungi (AMF).The transfer and metabolism of C and N in the symbiosis plays an important role in keeping nutrient balance and resource reallocation between the host plant and the fungi.The carbohydrates produced by plant photosynthesis are transferred to the fungi,where they are metabolized as materials and energy used for fungal spore germination,mycelium growth and uptake of nitrogen and other nutrients.At the same time,N is transferred and reallocated from the fungi to the host plant,where the final released ammonium is used for plant growth.Accordingly,we reviewed the current progress in C and N transfer and metabolism in the AM symbiosis,and the crosstalk between them as well as some key issues to elucidate the mechanism of the interaction between C and N transport in the symbiosis,so as to provide the theory foundation for the application of AM in sustainable agriculture and ecosystem.
