“…In addition to increasing the sugar content in roots, AMF can increase the concentration of soluble sugars in the plant's leaves. For example, the total sugars and starch content in Heptacodium miconioides Rehder leaves were enhanced after AMF inoculation [25]. It is worth noting that the AMF effects are highly functional under low nutrient availability, especially in P deficiency conditions [23].…”

Medicinal and aromatic plants (MAPs) are able to synthesize a diverse group of secondary metabolites (SMs) such as terpenoids or terpenes, steroids, phenolics, and alkaloids with a broad range of therapeutic and pharmacological potentials. Extensive use of MAPs in various industries makes it important to re-evaluate their research, development, production, and use. In intensive agricultural systems, increasing plant productivity is highly dependent on the application of chemical inputs. Extreme use of chemical or synthetic fertilizers, especially higher doses of N fertilization, decrease the yield of bioactive compounds in MAPs. The plant–soil microbial interaction is an eco-friendly strategy to decrease the demand of chemical fertilizers. Arbuscular mycorrhizal fungi (AMF), belongs to phylum Glomeromycota, can form mutualistic symbiotic associations with more than 80% of plant species. The AMF–plant symbiotic association, in addition to increasing nutrient and water uptake, reprograms the metabolic pathways of plants and changes the concentration of primary and secondary metabolites of medicinal and aromatic plants. The major findings reported that inoculation of AMF with MAPs enhanced secondary metabolites directly by increasing nutrient and water uptake and also improving photosynthesis capacity or indirectly by stimulating SMs’ biosynthetic pathways through changes in phytohormonal concentrations and production of signaling molecules. Overall, the AMF-MAPs symbiotic association can be used as new eco-friendly technologies in sustainable agricultural systems for improving the quantity and quality of MAPs.

“…AMF increases the root absorption surface area, thereby enhancing the uptake of nutrients such as nitrogen and phosphorus, promoting photosynthesis, and regulating photosynthetic product distribution, ultimately improving plant growth [ 12 , 13 , 14 , 15 ]. Furthermore, AMF promotes the host plant’s resistance to adverse environmental stressors, including drought, heavy metals, microplastics, and biotic stresses such as pathogens and herbivory insects [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. In reciprocation, plants supply AMF with the necessary carbon sources for their growth and survival [ 26 , 27 ].…”

In nature, plants frequently experience concurrent colonization with arbuscular mycorrhizal fungi (AMF) and grass endophytes (Epichloë). These two fungi assist in mineral uptake and stress tolerance by the host. Despite the abundance of recent studies exploring the individual functions of these fungi in diverse ecosystems, research on the effects of the interaction between these two symbiotic fungi on the host, particularly in agricultural production and ecological conservation. This review provides an overview of the current knowledge regarding the interaction between AMF and grass endophytes and their synergistic effects on host plants in response to abiotic and biotic stress, while also outlining prospects for future research in this field. This knowledge not only enhances our comprehension of complex interaction effects between the two fungi, but also facilitates the optimal utilization of fungal resources, contributing to ecological construction and higher agricultural production.
