Special Issue Information

Dear Colleagues,

In natural environments, plant roots are usually associated with various soil microbes, such as arbuscular mycorrhizal (AM) fungi. AM fungi are ubiquitous soil fungi that form symbiotic associations with most terrestrial plants. The growth and functions of AM fungi depend on carbohydrates supplied by the plants; in return, the fungi assist the plants to acquire mineral nutrients (e.g., phosphorus) from soil. In addition, the beneficial effects of AM symbiosis have also been reported to improve plant tolerance to various environmental stresses, such as drought, salinity, and soil pollution. Recent studies have shown that plants grew better in poor or contaminated soils when their roots were colonized by AM fungi. Obviously, for potential use of AM fungi to alleviate stress and remedy poor or contaminated soils, it is important to uncover the physiological and biochemical mechanisms of metabolism and detoxification in mycorrhizal symbiont under stress. This Special Issue of the Journal of Fungi will present original research progress on the topic of “Arbuscular Mycorrhizal under Stress”, expecting to promote the process of development in the tolerance mechanisms of AM symbiont under stress.

Moringa oleifera (LAM) is a multipurpose tree species with extensive pharmacological and ethnomedicinal properties. Production of important medicinal plants is facing decline under changing climatic conditions, which brings along exacerbated abiotic stresses like salinity and intraspecific competition, particularly high planting densities. Increasing plant density is seen as a strategy to increase production; however, the intraspecific competition and a lack of arable land limit productivity. Salinity has been estimated to harm approximately six percent of the Earth’s landmass. This leads to a loss of over 20% of agricultural output annually. These stressors can significantly curtail moringa’s growth and yield potential. Literature designates that Arbuscular Mycorrhizal Fungi (AMF), ubiquitous soil microorganisms forming symbiotic associations with plant roots, offer a promising avenue for mitigating these stresses. This narrative review aims to investigate the utilization of AMF to alleviate the detrimental effects of salinity and high planting density on Moringa oleifera. The different adaptive strategies M. oleifera undergoes to mitigate both stressors are explored. The review found that AMF inoculation enhances plant tolerance to these stressors by improving nutrient acquisition, water relations, and activating stress response mechanisms. By facilitating improved nutrient and water absorption, AMF enhance root architecture, modulate ROS scavenging mechanisms, and promote optimal biomass allocation, ensuring better survival in high-density plantings. Furthermore, AMF-mediated stress alleviation is linked to enhanced physiological efficiency, including increased chlorophyll content, root–shoot biomass balance, and ion homeostasis. This review is important because it could provide insights into a sustainable, natural solution for improving the resilience of Moringa oleifera under adverse environmental conditions, with potential applications in global agriculture and food security. Future research should prioritize identifying and characterizing moringa-specific AMF species and evaluate the long-term efficacy, feasibility, and economic viability of AMF application in real-world moringa cultivation systems to fully harness the potential of AMF in moringa cultivation.
