Research Progress of Mycorrhizal Fungi Promoting Nitrogen and Phosphorus Uptake in Plants

Mycorrhizal fungi are a kind of plant symbiont ubiquitous in nature. The mutual-symbiotic relationship between mycorrhizal fungi and plants can promote the activation and release of mineral nutrients in soil, improve the biological availability of soil nutrients, and thus improve the nutritional status of plants. In this paper, the research progress of how mycorrhizal fungi take up nitrogen and phosphorus, the molecular mechanism of nitrogen and phosphorus metabolism and transport, and the influence of mycorrhizal fungi on plant uptake of nitrogen and phosphorus from the aspects of mycelial structure, physiology, biochemistry and molecular biology were introduced. And the main problems and future research priorities were also analyzed.
