Research progress of nitrogen cycle mechanism of ectomycorrhizal fungi
In order to adapt to the complex ecological environment,plants and soil fungi form a mutually beneficial symbiotic association-mycorrhiza.The establishment of mycorrhiza is based on the nutrient exchange between the plants and fungi.Fungi provide nutrients such as nitrogen and phosphorus sources for plants.In return,plants provide carbon source for fungus growth.The nutrient metabolism and communication between ectomycorrhizal fungi and symbiotic plants is a research hotspot at home and abroad.The article mainly summarized the research progress of ectomycorrhizal fungi nitrogen cycle at home and abroad and described the uptake of nitrogen sources in soil by ectomycorrhizal fungi and the interaction mechanism with plants.The article also listed the proven compounds and enzymes in the nitrogen cycle pathway of ectomycorrhizal fungi.The article looked forward to future research directions and discusses in depth the mutual nutrition and information exchange between ectomycorrhizal fungi and symbiotic plants.
