The increasing challenges due to climate change and environmental stresses, such as drought, salinity, soil degradation, phytopathogens and insect pests necessitate innovative approaches for increasing crop resilience and productivity. This chapter focuses on the role of soil-inhabiting beneficial fungi in promoting plant growth and protecting crops against various biotic and abiotic stresses in Iran. Various types of beneficial fungi are recognized with the ability to enhance nutrients uptake, improve soil structure, growth stimulation and resistance induction in the host plant via various modes of action. Numerous mechanisms might be involved in functioning these beneficial microbes, including production or regulation of phytohormones and antimicrobial compounds, also affecting the host defense components, such as antioxidant systems, phenolics, flavonoids, lignin, callose and complex networks of defense-related signaling pathways. These fungi also contribute to soil health by enhancing microbial diversity and activity, which is crucial for nutrient cycling and soil fertility. In Iran, application of soil-inhabiting beneficial fungi has been considered as an effective strategy for improving plant protection and producing organic agricultural products with high quantity and quality. Present chapter discusses the current status of research on the soil-inhabiting endophytic, rhizospheric and mycorrhizal fungi in Iran, their mechanisms of action, and applications strategies in sustainable agriculture. Furthermore, it highlights the need for integrated approaches, which combine the use of beneficial fungi or their metabolites with other sustainable practices to enhance plant production and crop protection via decreasing the adverse effects of environmental stimuli. Overall, this section of the book aims to provide a comprehensive overview on the potential of soil-inhabiting beneficial fungi as a main component in promoting plant growth, protecting crops, and contributing to the development of sustainable agricultural systems in the face of increasing environmental challenges.

摘要

The increasing challenges due to climate change and environmental stresses, such as drought, salinity, soil degradation, phytopathogens and insect pests necessitate innovative approaches for increasing crop resilience and productivity. This chapter focuses on the role of soil-inhabiting beneficial fungi in promoting plant growth and protecting crops against various biotic and abiotic stresses in Iran. Various types of beneficial fungi are recognized with the ability to enhance nutrients uptake, improve soil structure, growth stimulation and resistance induction in the host plant via various modes of action. Numerous mechanisms might be involved in functioning these beneficial microbes, including production or regulation of phytohormones and antimicrobial compounds, also affecting the host defense components, such as antioxidant systems, phenolics, flavonoids, lignin, callose and complex networks of defense-related signaling pathways. These fungi also contribute to soil health by enhancing microbial diversity and activity, which is crucial for nutrient cycling and soil fertility. In Iran, application of soil-inhabiting beneficial fungi has been considered as an effective strategy for improving plant protection and producing organic agricultural products with high quantity and quality. Present chapter discusses the current status of research on the soil-inhabiting endophytic, rhizospheric and mycorrhizal fungi in Iran, their mechanisms of action, and applications strategies in sustainable agriculture.
