“…A significant decrease was observed in plants treated with AMF under both control and saline conditions. Analogous responses have been denoted by Fattahi et al (2021), who suggested that AMF contributes to the reduction of membrane lipid peroxidation in pistachio under salt stress. Furthermore, this reduction in MDA and EL is mainly due to AMF's ability to alleviate the negative effects of ROS on plant cells, as reported by Evelin et al (2019).…”

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.

“…Enhanced K + and decreased Na + uptake into shoot tissues may be observed as an additional mechanism for ion homoeostasis in sweet basil plants induced by the mycorrhizal fungus— Glomas intraradices (Zuccarini & Okurowska, 2008). Also, the inoculation of AMF to salt‐stressed pistachio rootstocks was reported to accelerate the uptake of phosphorous, calcium, and magnesium ions along with nitrogen uptake and decrease in Na + and Cl − (Fattahi et al, 2021). Similar effects on mineral uptake in case of salt‐stressed date palm seedlings inoculated with spore mixture of AMF containing Glomus sp., Sclerocystis sp., and Acaulospora sp.…”

Soil salinity severely affects plant growth and development and imparts inevitable losses to crop productivity. Increasing the concentration of salts in the vicinity of plant roots has severe consequences at the morphological, biochemical, and molecular levels. These include loss of chlorophyll, decrease in photosynthetic rate, reduction in cell division, ROS generation, inactivation of antioxidative enzymes, alterations in phytohormone biosynthesis and signaling, and so forth. The association of microorganisms, viz. plant growth‐promoting rhizobacteria, endophytes, and mycorrhiza, with plant roots constituting the root microbiome can confer a greater degree of salinity tolerance in addition to their inherent ability to promote growth and induce defense mechanisms. The mechanisms involved in induced stress tolerance bestowed by these microorganisms involve the modulation of phytohormone biosynthesis and signaling pathways (including indole acetic acid, gibberellic acid, brassinosteroids, abscisic acid, and jasmonic acid), accumulation of osmoprotectants (proline, glycine betaine, and sugar alcohols), and regulation of ion transporters (SOS1, NHX, HKT1). Apart from this, salt‐tolerant microorganisms are known to induce the expression of salt‐responsive genes via the action of several transcription factors, as well as by posttranscriptional and posttranslational modifications. Moreover, the potential of these salt‐tolerant microflora can be employed for sustainably improving crop performance in saline environments. Therefore, this review will briefly focus on the key responses of plants under salinity stress and elucidate the mechanisms employed by the salt‐tolerant microorganisms in improving plant tolerance under saline environments.

“…However, in vines growing under salinity stress, the oxidative reaction is caused by increasing reactive oxygen species in root tissue cells, leading to enhanced lipid peroxidation processes [ 43 ], a result of which is increased cell permeability afterward [ 44 ], as well as disrupting the metabolic equilibrium [ 45 ]. Salinity stress induces the creation of H 2 O 2 , which hydroperoxides the unsaturated fatty acids in bio-membranes and is produced as a byproduct of aldehyde breakdown, such as MDA [ 46 , 47 , 48 ].…”

The growth and quality of vines are negatively affected by soil salinity if enough salts accumulate in the root zone. As part of the current study, we estimated the remediating effects of rootstocks under salinity. For this reason, “superior seedless” vines were grafted onto three different rootstocks, such as SO4, 1103 Paulson, and own-root (“superior seedless” with their own-root). The experiment was conducted in the 2019 and 2020 seasons. This study examines the effects of different rootstocks on vine growth, yield, and quality using “superior seedless” vines grown in sandy soil with salinity. Four stages of berry development were examined (flowering, fruit set, veraison, and harvest time). At harvest, yield characteristics (clusters per vine and cluster weight) were also assessed. Each parameter of the growth season was influenced separately. The K+ and Na+ ratios were also significantly increased, as were the salinity symptoms index and bunch yield per vine and quality. Rootstock 1103 Paulson improved photosynthetic pigments, K+ accumulation, Na+ uptake, and cell membrane damage in “superior seedless” vines compared to other rootstocks, according to the study results. As determined in the arid regions of northwestern Egypt, the 1103 Paulson can mitigate salinity issues when planting “superior seedless” vines on sandy soil.
