[Research progress on ecological function of arbuscular mycorrhizal network]

Area of Science:

• Ecology
• Soil Science
• Mycology

Background:

• Arbuscular mycorrhizal (AM) fungi are crucial soil microorganisms forming extensive underground networks (AMN).
• AMN influences soil properties, microbial communities, and plant dynamics within terrestrial ecosystems.

Purpose of the Study:

• To review the multifaceted functions of AMN in ecosystems.
• To explore AMN's role in soil structure, microbial regulation, resource distribution, plant competition, and ecosystem stability.

Main Methods:

• Literature review synthesizing existing research on AMN.
• Analysis of AMN formation, regulation of soil microorganisms, resource distribution, and responses to global changes.

Main Results:

• AMN formation involves hyphal fusion, creating extensive underground networks.
• AMN significantly alters soil physical and chemical properties, influencing microbial community structure and function.
• AMN mediates nutrient transport, affecting plant competition, diversity, and abundance.
• AMN plays a role in ecosystem stability concerning nitrogen deposition, CO2, and temperature.

Conclusions:

• AMN are key players in ecosystem functioning, influencing soil health, plant communities, and stability.
• Understanding AMN is vital for predicting ecosystem responses to global environmental changes.
