“…Bioinoculants are interesting alternatives that contribute to achieving this goal owing to the prominent role they play in the ecological fitness of crops and soil health. Inoculation with AMF has the potential to promote crop yield and quality, and to protect crops against abiotic stress and pathogen attacks [46][47][48][49]. AMF also promote soil health by enhancing soil aggregate formation through the production of glomalin-related proteins, facilitating the biogeochemical cycle of soil minerals, controlling the turnover of soil organic matter, and promoting carbon sequestration [50][51][52].…”

Interventions with commercial inoculants have the potential to reduce the environmental footprint of agriculture, but their indiscriminate deployment has raised questions on the unintended consequences of microbial invasion. In the absence of explicit empirical reports on arbuscular mycorrhizal fungi (AMF) invasion, we examine the present framework used to define AMF invasion and offer perspectives on the steps needed to avoid the negative impacts of AMF invasion. Although commercial AMF isolates are potential invaders, invasions do not always constitute negative impacts on native community diversity and functions. Instead, the fates of the invading and resident communities are determined by ecological processes such as selection, drift, dispersal, and speciation. Nevertheless, we recommend strategies that reduce overdependence on introduced inoculants, such as adoption management practices that promote the diversity and richness of indigenous AMF communities, and the development of native propagules as a supplement to commercial AMF in applicable areas. Policies and regulations that monitor inoculant value chains from production to application must be put in place to check inoculant quality and composition, as well as the transport of inoculants between geographically distant regions.

“…AMF colonization improves root hydraulic conductivity and root development in onions, resulting in a larger surface area for nutrient and water absorption [8]. Additionally, AMF enhances resistance to water stress by boosting the absorption of critical plant nutrients such as N and P, which encourages the host plant's development and increases tolerance to water stress [9].…”

Water stress negatively impacts the physiology of plants, affecting their growth and development. It is considered among the most important environmental factors responsible for reduced crop production. In this regard, biofertilizers may be considered significant for their reparative properties to increase stress tolerance in crop plants. We studied the effects of water stress on the morphological and biochemical characteristics of onion plants with AMF (Funneliformis mosseae) and potassium silicate application. The water stress significantly affected all the studied traits, each with minimum recorded levels. Plants that received combined treatments of AMF and potassium silicate showed maximum percent increments in all the studied characteristics, e.g., plant height (156.7%), weight of bulb (416.8%), antioxidant activity (224.0%), membrane stability index (74.5%), relative water content (87.3%), and total soluble solids (63.71%). Therefore, the study demonstrated that all the investigated variables were affected negatively by water stress. However, bio-fortification of onion plants with silicates and AMF inoculation may be considered useful for functional food production, with numerous health promoting properties.

But at elevated CO 2 AM sour orange plants were 15% larger than non-mychorrhizal plants.…”

Agriculture is the mainstay between humans and the environment. The existence of arbuscular mycorrhizal fungi (AMF), on the earth, is about 600 million years ago. The application of mycorrhizae as biofertilizer is in increasing trend. Mycorrhizae improve several agricultural practices like better nutrient cycling, improving crop yield, and remediation of toxic heavy metals from soil. There is much variation in arbuscular mycorrhizal association although 80% of the plant species are infected with mycorrhizae. Mycorrhizal dependency (MD) is defined as the degree to which a host plant is dependent on AMF to produce maximum growth or yield at a given level of soil fertility. Plant with high MD need to feed with a higher amount of carbon and lipid to the fungus than a plant with less MD. Mycorrhizae modify, maintain, and create habitat by directly and indirectly regulating biotic and abiotic environments. Mycorrhizae derived photosynthetically formed C for the growth and uptake, tolerance against abiotic stress such as drought, heavy metals, salinity as well as protecting from pathogen attack to host plant and preventing from erosion. Application of ZnO would have been the probable solution of mitigating drought.ZnO treatment decreased the adverse effects of drought stress in plants by enhancing antioxidant enzyme activity and changing physiological parameters. Heat stress affects many processes in a variety of plants as water relations, nutrient uptake, photosynthesis, assimilate partitioning, respiration, growth, and reproduction, and induced oxidative damage. Foliar application of ZnSO4.7H2O effectively alleviated by enhancing Zn concentration, superoxide dismutase activity, chlorophyll content, Fv/Fm ratio, and photosystem II under heat stress. In maize, there is a substantial reduction of germination above 37oC. All the parameters recorded in wheat, namely, no of tillers, plant height, spike length, no of spikelets per spike, no of grains per spike, 1000 grain weight, biological yield, grain yield and harvesting index, Ca, Mg, Fe, Zn, Cu and protein content are significantly affected by the mycorrhizal application. Almost 25% of recommended dose of phosphate fertilizer could be saved as in Niger(Guizotia abyssinica)by inoculating Glomusmosseae. Zinc is a vital micronutrient for many plants but its excess can be calamitous.AMF contributes to plant Zn uptake but their role in the edible portion of the crop has not been studied yet. The mycorrhizal pathway of Zn uptake contributed up to 24.3% of the total above-ground Zn in wheat and up to 12% of that Zn in Barley. The greatest contribution by the mycorrhizal pathway was observed in Barley at the lowest Zn addition and in wheat at the .highest one. Besides the grain yield of bread wheat was increased by AMF.
