Salinization of soil is a major problem affecting many plant physiological processes. The use of arbuscular mycorrhizal fungi (AMF) plays a key role in improving the growth and the crops yield. The aim of this study was to evaluate the combined effects of salt stress and AMF on agro-physiological and biochemical responses of Stevia rebaudiana Bertoni. The experiment was carried out in a completely randomized design with ten replicates under the green house conditions. Stevia plants were inoculated with AMF consortium (MC) or with Rhizophagus irregularis (Ri) on the presence (80 mM of NaCl) or the absence (0 mM of NaCl) of salt stress. The results showed that plant height, dry biomass of shoots and roots parts, mycorrhizal frequency and intensity, relative water content, chlorophyll fluorescence, stomatal conductance, chlorophyll a, and total chlorophyll were significantly reduced by 29%, 72%, 36%, 84%, 65%, 24%, 17%, 60%, 28.50%, and 40.9% respectively under salt stress. These changes were associated with a significant increase in antioxidant enzymes (activity of polyphenol oxidase, peroxidase, superoxide dismutase, and catalase), electrolyte leakage, lipid peroxidation, and hydrogen peroxide contents. The application of AMF (MC and Ri) improved growth and physiological parameters through rising the activities of antioxidant enzymes and reduction of the oxidative damage caused by the salt stress. The better results were recorded with MC-inoculated plants. These findings suggested that AMF could be an effective strategy to alleviate the adverse effects of salt stress on Stevia rebaudiana.

“…In this study, the effect of salt stress on superoxide dismutase activity in non-mycorrhizal chia plants was lower than that in mycorrhizal plants (Table 1). Shahvali et al (2020) reported that the application of arbuscular mycorrhizal fungi enhances the antioxidant system rendering them more Catalase activity occurred at the beginning of the symbiosis between G. mossae and asparagus plant roots (He et al, 2020). Soybean plants inoculated with G. intraradices in sufficient water or dry growing media showed high catalase activity (Etesami & Shafiei, 2020).…”

Plant productivity is often constrained by abiotic stress in the form of high salt levels. However, a symbiosis between plant and arbuscular mycorrhizal fungi can reduce the severity of the effect of salt stress on cultivated plants. The aim of this study was to determine the impact of salt stress on the antioxidant substances and biochemical parameters of chia (Salvia hispanica L.) plants that had been inoculated with the fungus Glomus manihotis. A factorial completely randomized design with seven replicates was used with status of inoculation by the fungus G. manihotis (inoculated vs. not inoculated) as one of factors and the concentration of sodium chloride (NaCl) (0, 50, 100, and 200 mM) as the other status factor. Several parameters in the chia plants were measured including: root infection, phosphorus content, chlorophyll and carotenoid contents, antioxidant enzyme activities (superoxide dismutase and catalase), and malondialdehyde content. The results showed that chia plants inoculated with G. manihotis (mycorrhizal plants), even under salt stress conditions, had higher phosphorus content than non-mycorrhizal plants. High salt levels reduced the percentage of root infection by the mycorrhizal fungus of G. manihotis. Under salt stress conditions, chlorophyll and carotenoid contents of chia leaves were higher in mycorrhizal plants than in non-mycorrhizal plants. The activities of superoxide dismutase and catalase of mycorrhizal chia plants were higher than those of non-mycorrhizal plants, even though they were grown under conditions of high salt levels. The malondialdehyde content of chia plants increased with salt concentration, but decreased in chia plants inoculated with G. manihotis. The findings of this study indicate that G. manihotis inoculation is effective in reducing the effect of salt stress on chia plants.

“…Increases in shoot dry weight and chlorophyll contents, and less accumulation of Na + and Cl − in photosynthetic organs were reported. Salt tolerance of almond rootstocks was increased by the AM fungi R. intraradices and Funneliformis mosseae through the improvement of diverse physiological parameters like chlorophyll, soluble sugars and proline content, osmotic parameters, and increased activity of antioxidant enzymes (Shahvali et al, 2020).…”

Global climate changes have serious consequences on natural ecosystems and cause diverse environmental abiotic stressors that negatively affect plant growth and development. Trees are dependent on their symbiosis with mycorrhizal fungi, as the hyphal network significantly improves the uptake of water and essential mineral nutrients by colonized roots. A number of recent studies has enhanced our knowledge on the functions of mycorrhizal associations between fungi and plant roots. Moreover, a series of timely studies have investigated the impact and benefit of root symbioses on the adaptation of plants to climate change-associated stressors. Trees in temperate and boreal forests are increasingly exposed to adverse environmental conditions, thus affecting their durable growth. In this mini-review, we focus our attention on the role mycorrhizal symbioses play in attenuating abiotic stressors imposed on trees facing climatic changes, such as high temperatures, drought, salinity, and flooding.
