“…It is worth noting that the nutrient concentration of thyme under well-watered and water stress conditions sharply increased by co-application of AMF+CHT NPs. It seems that the symbiotic association of AMF with thyme roots enhances nutrient concentration by increasing the absorption rate and area as a result of extensive underground extra-radical mycelia and also acidification of the rhizosphere area by the release of H + [ 30 ]. Additionally, the higher nutrient content by CHT NPs application could be attributed to the higher surface area to the volume and slower diffusion of nanoparticles [ 31 ].…”

Water stress is one of the critical abiotic stresses and limiting factors in the productivity of plants, especially in arid and semi-arid regions. In recent years, the application of bio-fertilizer and stress-modulating nanoparticles (NPs) is known as one of the eco-friendly strategies for improving plants quantity and quality under stressful conditions. In order to achieve the desirable essential oil (EO) quality and quantity of thyme in water deficit conditions, a 2-year field experiment was carried out as a split plot based on the randomized complete block design (RCBD), with 12 treatments and three replications. The treatments included different irrigation levels, containing irrigation at 80% field capacity (FC80) as no stress, 60% FC as moderate water stress (FC60) and 40% FC as severe water stress (FC40), as well as four different fertilizer sources, including non-application of fertilizer (control), application of arbuscular mycorrhizal fungi (AMF), chitosan NPs (CHT) and co-application of AMF+CHT NPs. The results demonstrated that the dry yield of thyme decreased by 13% and 40.3% under FC60 and FC40 water stress conditions. However, co-application of AMF+CHT NPs enhanced the dry yield of thyme by 21.7% in comparison to the control (non-application of fertilizer). The maximum EO content (2.03%) and EO yield (10.04 g 7 g m−2) of thyme were obtained under moderate water stress (FC60) fertilized with AMF+CHT NPs. Co-application of AMF+CHT NPs enhanced the EO content and EO yield of thyme by 17.1% and 42.7%, respectively. Based on the GC-MS and GC-FID analysis, 38 constituents were identified in the thyme EO, with the major constituents being thymol (35.64–41.31%), p-cymene (16.35–19.38%), γ-terpinene (12.61–13.98%) and carvacrol (2.78–3.93%) respectively. The highest content of thymol and γ-terpinene was obtained under moderate water stress (FC60) fertilized with AMF+CHT NPs. In addition, the highest content of p-cymene and carvacrol was observed in the severe water stress (FC40) fertilized with AMF+CHT NPs. The present research suggests that the co-application of AMF+CHT NPs represents a sustainable and eco-friendly strategy for improving the EO quantity and quality of thyme under water stress conditions.

“…The ability of AMF to mitigate heavy metal toxicity is attributed to their extensive hyphal network, which extends beyond the root zones, effectively reducing the concentration and leaching of toxic metal like Cd, Zn and Pb [11]. The organic compounds they release, such as polysaccharides and proteins, further enhance soil adsorption of heavy metals, thus reducing their bioavailability [12,13]. Notably, AMF has been shown to decrease plant uptake of heavy metals, enhancing growth in metal-stressed environments [10] This has been observed in various crops, including maize, where studies have demonstrated the beneficial effects of AMF in mitigating heavy metal stress [10,14].…”

The rise in industrial activity has resulted in an escalating threat antimony (Sb) buildups and biomagnifications in both plants and humans. Arbuscular mycorrhizal fungi (AMF) have been thoroughly investigated as a soil enhancement due to their ability to decrease the accumulation of many heavy metals in plant tissues. However, a quantitative and data-based consensus has yet to be reached on the effect of AMF application on maize plants, focusing on plant growth, nutrient content, and antioxidant properties in maize grains subjected to antimony treatment. A notable decrease in AMF-related parameters, including colonization, hyphal length, and arbuscules, was noted when AMF was combined with Sb compared to AMF alone. The AMF treatment alone enhanced plant growth, as indicated by the increased fresh and dry biomass, while Sb treatment alone reduced substantially the total fresh (66%) and dray weight (65%). However, combining AMF with Sb resulted in significant variations in macro- and micronutrients in maize grains. Notably, the combined AMF and Sb treatment influenced the nutritional value of maize grains, showing increased levels of organic acids, amino acids, and fatty acids compared to control. Furthermore, antioxidant activity of maize grains was enhanced by AMF inoculation, as indicated by high levels of polyphenols (39%), flavonoids (63%), ascorbic acid (ASC) (71%), and glutathione (GSH) (28%) content as response to Sb application. Also, a 33% rise in total tocopherol was noted, reflecting comparable upward trends. These findings suggest that the co-application of AMF and Sb can positively influence maize nutritional quality and antioxidant properties of maize grains, offering benefits for sustainable agricultural practices.

“…In contrast to nematode, arbuscular mycorrhizal fungi form beneficial interaction with plant roots to complete their life cycle [11]. These fungi improve plant's water and nutrient uptake, especially phosphorus (P), while the plant provides 10-20% of the photosyntates to the fungi [12,13]. These fungi are characterized by the formation of highly branched structures for nutrient exchange between the symbionts, called arbuscules.…”

The arbuscular mycorrhiza fungus Glomus can increase plant’s water and nutrient uptake and provide protection against plant parasitic nematodes. This study aimed to determine the response of soybean and tomato plants under inoculation with Glomus sp. and root-knot nematode Meloidogyne incognita at different application times in pot experiments. On soybean, Glomus sp. alone or in combination with M. incognita significantly increased plant height, while simultaneous inoculation of both microorganisms significantly increased the root dry weight. The total leaf P content of soybean however, significantly decreased in response to all inoculation methods. On tomato plants, Glomus alone significantly increased tomato shoot dry weight, total plant dry weight, and the total leaf P content. The final nematode population, the number of nematodes penetrating the root, and the root gall scores were not significantly impacted by either Glomus or M. incognita inoculation The inconsistent effect of Glomus inoculation on plant growth and total leaf P content as well as the inability of Glomus to reduce M. incognita infestation may be contributed by the extent of root colonization by Glomus and variability in the species of Glomus.
