“…Osmotic adjustment is one of the plant strategies to minimize the adverse effects of environmental stress [ 89 , 90 ]. Apart from osmoregulation, the metabolisms of organic acids may also act as ROS scavengers and signalling molecules in overcoming abiotic stress [ 91 , 92 ]. In agreement with these findings, the reduced accumulation of ROS and MDA (Fig.…”

Background Arbuscular Mycorrhizal Fungi (AMF) are beneficial microorganisms in soil-plant interactions; however, the underlying mechanisms regarding their roles in legumes environmental stress remain elusive. Present trials were undertaken to study the effect of AMF on the ameliorating of salt, drought, and cold stress in peanut (Arachis hypogaea L.) plants. A new product of AMF combined with Rhizophagus irregularis SA, Rhizophagus clarus BEG142, Glomus lamellosum ON393, and Funneliformis mosseae BEG95 (1: 1: 1: 1, w/w/w/w) was inoculated with peanut and the physiological and metabolomic responses of the AMF-inoculated and non-inoculated peanut plants to salt, drought, and cold stress were comprehensively characterized, respectively. Results AMF-inoculated plants exhibited higher plant growth, leaf relative water content (RWC), net photosynthetic rate, maximal photochemical efficiency of photosystem II (PSII) (Fv/Fm), activities of antioxidant enzymes, and K+: Na+ ratio while lower leaf relative electrolyte conductivity (REC), concentration of malondialdehyde (MDA), and the accumulation of reactive oxygen species (ROS) under stressful conditions. Moreover, the structures of chloroplast thylakoids and mitochondria in AMF-inoculated plants were less damaged by these stresses. Non-targeted metabolomics indicated that AMF altered numerous pathways associated with organic acids and amino acid metabolisms in peanut roots under both normal-growth and stressful conditions, which were further improved by the osmolytes accumulation data. Conclusion This study provides a promising AMF product and demonstrates that this AMF combination could enhance peanut salt, drought, and cold stress tolerance through improving plant growth, protecting photosystem, enhancing antioxidant system, and regulating osmotic adjustment.

“…For instance, the content of glycyrrhizic acid, a triterpenoid saponin used to alleviate bronchitis, gastritis, and jaundice (Pastorino et al 2018), was increased by 0.38-1.07-fold and by 1.34-1.43-fold after 4 and 30 months, respectively, in Glycyrrhiza glabra (liquorice) plants colonized by F. mosseae and D. epigaea alone or in combination, grown in sand under greenhouse conditions (Liu et al 2007). Similarly, Johny et al (2021) reported an increase of glycyrrhizic acid concentration in Glycyrrhiza glabra inoculated with C. etunicatum under greenhouse conditions.…”

Johny et al (2021) reported that association between the medicinal plant Withania somnifera and R. irregularis increased the concentration of withaferin-A as compared to non-inoculated plants under greenhouse conditions.…”

Arbuscular mycorrhizal fungi and production of secondary metabolites in medicinal plants

Medicinal plants are an important source of therapeutic compounds used in the treatment of many diseases since ancient times. Interestingly, they form associations with numerous microorganisms developing as endophytes or symbionts in different parts of the plants. Within the soil, arbuscular mycorrhizal fungi (AMF) are the most prevalent symbiotic microorganisms forming associations with more than 70% of vascular plants. In the last decade, a number of studies have reported the positive effects of AMF on improving the production and accumulation of important active compounds in medicinal plants.In this work, we reviewed the literature on the effects of AMF on the production of secondary metabolites in medicinal plants. The major findings are as follows: AMF impact the production of secondary metabolites either directly by increasing plant biomass or indirectly by stimulating secondary metabolite biosynthetic pathways. The magnitude of the impact differs depending on the plant genotype, the AMF strain, and the environmental context (e.g., light, time of harvesting). Different methods of cultivation are used for the production of secondary metabolites by medicinal plants (e.g., greenhouse, aeroponics, hydroponics, in vitro and hairy root cultures) which also are compatible with AMF. In conclusion, the inoculation of medicinal plants with AMF is a real avenue for increasing the quantity and quality of secondary metabolites of pharmacological, medical, and cosmetic interest.

“…In addition to using green manures in sustainable agricultural systems, the application of organic manures (such as vermicompost) [ 14 ] and biofertilizers (such as arbuscular mycorrhizal fungi) can positively affect the plant’s productivity and its quality [ 15 ]. Arbuscular mycorrhizal fungi (AMF) can establish symbiotic association with more than 80% of the plant’s roots and affect the plant’s performance through improving nutrient accessibility, especially P and other micro-nutrients such as Zn and Fe, increasing water uptake and promoting the photosynthesis rate and also enhancing plant tolerance in the face of stressful conditions [ 16 , 17 ]. It has been reported that the inoculation of different AMF species improves the EO quality and quantity of medicinal and aromatic plants [ 18 ].…”

Nowadays, the application of sustainable and eco-friendly fertilizers plays an important role in improving the essential oil (EO) quantity and quality of medicinal and aromatic plants. Hence, the study aimed to investigate the effects of green manures, organic manures and biofertilizers on the nutrient content, dry matter yield, EO productivity and quality of peppermint. The treatments included green manures [barley monoculture (Bm), hairy vetch monoculture (HVm) and replacement intercropping of 75%HV + 25%B, 50%HV + 50%B and 25%HV + 75%B], arbuscular mycorrhizal fungi (AMF) and vermicompost (VC). A 50%HV + 50%B green manure appears to be the most effective treatment, since it provides the greatest amount of nutrients (N and K, 18.8 g kg−1, and 18.1 g kg−1, respectively), the tallest plants (61.5 cm), the most nodes per plant (17.5), the lateral branches (24.4), the highest leaf greenness index (45.5) and dry yield (266.7 g m−2) in peppermint. Moreover, this treatment evidenced the larger EO content (1.8%) and EO yield (4.84 g m−2). Regardless of the treatments, the chemical composition of peppermint EO was characterized by menthol (32.35–37.73%), menthone (16.96–20.64%) and 1,8-cineole (6.18–7.78%). The maximum content of menthol and 1,8-cineole was obtained by the application of 50%HV + 50%B. Additionally, the highest content of menthone was observed in AMF treatment. These results indicate that the application of 50%HV + 50%B green manures could be suggested as an environmentally friendly strategy for improving EO quantity and quality of peppermint.
