“…These include arbuscular mycorrhizal fungi (AMF) and plant growthpromoting rhizobacteria (PGPR), which exhibit considerable salt tolerance and have great potential to promote plant growth in saline and sodic soils (Arora 2021). Many problems occur for cultivated plants under salinity/alkalinity, including high uptake and accumulation of Na + in leaves, which increase the reactive oxygen species (ROS) and decrease the uptake of essential nutrients, which reduces plant productivity (Munir et al 2021).…”

“…The role of nanofertilizers or nutrient nanoparticles under stresses has been investigated for crops such as rice (Kheir et al 2019), faba bean (El-Sharkawy et al 2021), and banana (Ding et al 2022). In addition to nanofertilizers, halophytic-based nanoparticles have been shown to improve crop productivity under salinity stress by improving water use efficiency and enhancing the plants' ion flux, plant photosynthesis efficiency, the production of proteins involved in oxidation-reduction reactions, detoxification of ROS, and hormonal signaling pathways (Mall et al 2021;Munir et al 2021). Integrated management using both nano-Zn, and nano-Si in addition to using straw-filled ditches The following strategies are proposed to develop sustainable approaches and solutions, separately and/or in combination, to improve productivity of crops and their nutrition under saline conditions (Ondrasek et al 2022): 1-Production of genotypes or varieties tolerant to salinity or transfer genes for salinity tolerance from halophytes through breeding and genetic approaches, 2-Management of soil, water, and crops to control and avoid the detrimental effects of salinity to crops by application of specific agro/technical/technological options such as application of modern, low pressure, localized irrigation, improved drainage and tillage, grafting onto salt -tolerant rootstocks, and seed priming, 3-Application of organic and inorganic soil amendments such as organic fertilizers (compost), ZnSO 4 , gypsum, lime, Si-enriched materials, phytohormones, nanomaterials like nanofertilizers and nano-based growth promotors, and 4-Detection and monitoring of soil salinity using remote sensing, salinity monitoring, ecological indicators, and mega-data analyses.…”

oil is the main source of human food, feed for our animals, fiber, and a major source of fuel. The ability of soil to supply life essentials can be impacted by several obstacles that reduce or prevent plant production. Salt-affected soils are common under arid and semi-arid climates, which often produce soils that have salinity and/or alkalinity problems. Salinity and alkalinity are important stresses, mainly including oxidative and osmotic stress, which threaten crop productivity under such soil conditions and can cause significant yield reductions. Successful production in such soils needs a deep understanding of their formation and productivity challenges. Due to the increased areas of salt-affected soils in the world, the management of these soils is a crucial global issue. This paper is a mini-review on salt-affected soils, which include their characterization and suitable management approaches. Nano-management of salt-affected soils as a promising approach will also be discussed and new perspectives and challenges in reclamation of salt-affected soils will be highlighted.

“…The well-known sea (salt-tolerant) rice cultivation has been confirmed as improving the potential of saline-alkali land and ensuring food security [ 6 ]. Therefore, screening good salt-tolerant varieties and mining salt-tolerant genes are the effective approaches to dealing with environmental stress in recent years [ 7 ].…”

Soil salinization seriously affects the growth and distribution of flax. However, there is little information about the salt tolerance of flax. In this study, the salt tolerance of 200 diverse flax accessions during the germination stage was evaluated, and then the Genome-wide Association Study (GWAS) was carried out based on the relative germination rate (RGR), relative shoot length (RSL) and relative root length (RRL), whereby quantitative trait loci (QTLs) related to salt tolerance were identified. The results showed that oil flax had a better salt tolerance than fiber flax. A total of 902 single nucleotide polymorphisms (SNPs) were identified on 15 chromosomes. These SNPs were integrated into 64 QTLs, explaining 14.48 to 29.38% (R2) of the phenotypic variation. In addition, 268 candidate genes were screened by combining previous transcriptome data and homologous gene annotation. Among them, Lus10033213 is a single-point SNP repeat mapping gene, which encodes a Glutathione S-transferase (GST). This study is the first to use GWAS to excavate genes related to salt tolerance during the germination stage of flax. The results of this study provide important information for studying the genetic mechanism of salt tolerance of flax, and also provide the possibility to improve the salt tolerance of flax.

“…Nanoparticles penetrate the plant leaf and accumulate in the edible parts while some assimilate into the soil in the surrounding area of the plant. Some metal and metal oxide nanoparticles are toxic to the environment, such as Ag +1 , Fe +3 , Zn +2 , Al +3, and Ti +4 [ 32 ]. It was observed that when Brassica juncea was treated with silver nanoparticles it resulted in increased levels of antioxidant enzymes, for instance, guaiacol peroxidase, catalase, and ascorbate peroxidase, which resulted in decreased levels of reactive oxygen species (ROS) activity [ 33 ].…”

Plant salinity resistance results from a combination of responses at the physiological, molecular, cellular, and metabolic levels. This article focuses on plant stress tolerance mechanisms for controlling ion homeostasis, stress signaling, hormone metabolism, anti-oxidative enzymes, and osmotic balance after nanoparticle applications. Nanoparticles are used as an emerging tool to stimulate specific biochemical reactions related to plant ecophysiological output because of their small size, increased surface area and absorption rate, efficient catalysis of reactions, and adequate reactive sites. Regulated ecophysiological control in saline environments could play a crucial role in plant growth promotion and survival of plants under suboptimal conditions. Plant biologists are seeking to develop a broad profile of genes and proteins that contribute to plant salt resistance. These plant metabolic profiles can be developed due to advancements in genomic, proteomic, metabolomic, and transcriptomic techniques. In order to quantify plant stress responses, transmembrane ion transport, sensors and receptors in signaling transduction, and metabolites involved in the energy supply require thorough study. In addition, more research is needed on the plant salinity stress response based on molecular interactions in response to nanoparticle treatment. The application of nanoparticles as an aspect of genetic engineering for the generation of salt-tolerant plants is a promising area of research. This review article addresses the use of nanoparticles in plant breeding and genetic engineering techniques to develop salt-tolerant crops.
