Abstract:

Nitrogen is an essential element for plant growth and development.It is the main limiting factor of the primary productivity of terrestrial ecosystem and has important significance for plant growth and development.Mycorrhizal fungi form a symbiotic relationship with plants,promote plants to absorb nitrogen from the soil,reduce the restriction of nitrogen on plant growth,and enhance the nitrogen exchange between soil,mycorrhizal fungi,and plants,playing an important role in the nitrogen cycle.It reviewed the utilization of different forms of nitrogen by mycorrhizal fungi,their effects on plant nitrogen metabolism,and their ecological significance on soil nitrogen cycle.Based on the current research status of mycorrhizal fungi' impact on plant nitrogen utilization,it is suggested to combine genomics,transcriptome,proteomics and environmental genomics technologies,focus on studying the nitrogen transport mechanism of mycorrhizal fungi plant symbiosis,analyze the main path of nitrogen exchange and gene interaction network between mycorrhizal fungi, plant, and soil,so as to promote plant nitrogen utilization rate,reduce nitrogen fertilizer application,and promote sustainable agricultural development.

Key words: Mycorrhizal fungi, Nitrogen, Glutamine synthetase, Symbiosis, Metabolic mechanism
