“…Because reduced growth under salinity is partially caused by ion imbalances and/or non-availability of nutrient ions due to their competition with major ions (Na + and Cl − ) in the soil [ 99 ], the sustained growth of AMF+ plants under salinity is partially based on improved uptake of nutrients and maintaining favorable ionic ratios [ 100 ]. AMF inoculation can maintain the K + /Na + balance under salt stress.…”

Population growth and food necessity envisaged the dire need for supplementation to a larger community balance in food production. With the advent of the green revolution, agriculture witnessed the insurrection of horticultural fruit crops and field crops in enormous modes. Nevertheless, chemical fertilizer usage foresees soil pollution and fertility loss. Utilization of biocontrol agents and plant growth promotion by microbial colonization enrooted significant restoration benefits. Constant reliability for healthy foods has been emancipated across the globe stressing high nutritive contents among indigenous field crops like tomato (Solanum lycopersicum). However, stress tolerance mechanisms and efficient abatement require deeper insights. The applicability of arbuscular mycorrhizal fungi (AMF) poses as an ultimate strategy to minimize the deleterious consequences of abiotic stress such as salt, drought, temperature and heavy metal stress sustainably. The rational modality employing the application of AMF is one of significant efforts to lessen cell damages under abiotic stress. The novelty of the compilation can be redressed to cohesive literature for combating stress. The literature review will provide agricultural scientists worldwide in providing a rational approach that can have possible implications in not only tomato but also other vegetable crops.

“…Several studies have indicated that AMF have the ability to enhance plant tolerance to saline-alkaline stress through promoting plant growth, improving gas exchange, enhancing nutrient uptake and maintaining ion balance (Evelin et al 2009;Tisarum et al 2020). Mycorrhizal plants had higher net photosynthetic rate, stomatal conductance and chlorophyll content compared to non-mycorrhizal plants under saline-alkaline stress (Lin et al 2017;Kong et al 2020). AMF inoculation improves nutritional status of plants by absorbing and translocating mineral nutrients beyond rhizospheric zone (Rouphael et al 2015).…”

“…Although many studies have indicated the beneficial effects of AMF on salt stress alleviation in various plants (Shi-chu et al 2019;Tisarum et al 2020;Kong et al 2020), but the magnitudes of effect greatly differ among these studies. Simultaneously, the different impacts of AMF inoculation on the alleviation of salt stress have been also found in citrus seedlings with differential salinity tolerance (Navarro et al 2014).…”

Arbuscular mycorrhizal fungi (AMF) was considered as a biotechnological tool for plant stress tolerance improvement and degraded ecosystem restoration. However, the variations in the effects of AMF species and abundance on plant performance under stress condition have to be still investigated. The study was conducted to evaluate the mechanisms of five AMF species, single or mixture, on Leymus chinensis stress tolerance along a saline-alkaline gradient. The results showed that AMF enhanced plant stress tolerance by promoting plant growth, enhancing nutrient absorption, maintaining ion balance, and improving photosynthetic efficiency. Funneliformis mosseae, Rhizophagus intraradices and the mixture treatments had more beneficial effects than Diversispora versiformis and Acaulospora scrobiculata inoculations. Plant grown under high stress level exhibited more benefits from AMF symbiosis. Our study suggests that not only presence of AMF, but also the species and abundance should be considered to reveal the exact effects of AMF on plant saline-alkaline tolerance and degraded grassland restoration.

“…AMF endow soil and roots with a direct connection, enhance plant mineral nutrition, water acquisition and photosynthesis, and alleviate the adverse effects of abiotic stresses, such as heavy metals and drought stress [11][12][13]. Our previous study showed that AMF inoculation on seedling substrates can reduce the harm of saline-alkali land exerted on processing tomato [14]. In addition, the application of AMF can effectively overcome the continuous cropping obstacles in continuous cropping soil, to promote growth and development of many crops, such as pepper [15], soybean [16], and cucumber [17].…”

Background Despite significant limitations of growth medium reuse, a large amount of organic substrate is reused in soilless cultivation of horticultural crops in China. Arbuscular mycorrhizal fungi (AMF) can promote nutrient absorption and improve plant tolerance to biotic and abiotic stresses. However, the mechanisms governing the effects of AMF on crop growth in organic continuous cropping substrates have not been elucidated. Results In this study, we showed that the inoculation of AMF in continuous cropping substrates promoted growth and root development, and increased the root and NADP-malic enzyme (NADP-ME) activity of tomato seedlings. Root transcriptome analysis demonstrated that the plant hormone signal transduction pathway was highly enriched, and 109 genes that positively correlated with the AMF-inoculated plant phenotype were obtained by gene set enrichment analysis (GSEA), which identified 9 genes related to indole acetic acid (IAA). Importantly, the levels of endogenous IAA in tomato seedlings significantly increased after AMF inoculation. Furthermore, the application of AMF significantly increased the expression levels of NADP-ME1 and NADP-ME2, as well as the activity of NADP-ME, and enhanced the root activity of tomato seedlings in comparison to that observed without inoculation of AMF. However, these effects were blocked in plants treated with 2,3,5-triiodobenzoic acid (TIBA), a polar transport inhibitor of IAA. Conclusions These results suggest that IAA mediates the AMF-promoted tomato growth and expression of NADP-MEs in continuous cropping substrates. The study provides convincing evidence for the reuse of continuous cropping substrates by adding AMF as an amendment.
