Research Progress of Arbuscular Mycorrhizal Fungi Improving Plant Resistance to Temperature Stress

Abstract

Arbuscular mycorrhizal fungi (AMF) are beneficial microorganisms ubiquitous in soil that form symbiotic mycorrhizal structures with plant roots. When the host plant is exposed to temperature stress, arbuscular mycorrhizal fungi can improve the host plant’s resistance by helping regulate the growth of underground and aboveground parts. In recent years, due to climate change, extremely high and low temperatures have occurred more frequently and for longer durations, significantly impacting plant growth, antioxidant systems, osmotic balance, photosynthesis, and related gene expression. Consequently, numerous scholars have used arbuscular mycorrhizal fungi to aid plants, confirming that arbuscular mycorrhizal fungi can help host plants improve their ability to resist temperature stress. In this paper, the quantitative research method of Meta-analysis was used to collate and build a database of 129 relevant works to evaluate the effects of AMF on plant resistance to temperature stress and explore the response mechanism of AMF to host plants subjected to temperature stress, providing a theoretical basis for further exploring arbuscular mycorrhizal fungi in improving plant resistance to temperature stress.
