“…The production of more malondialdehyde (MDA) under salt-stress conditions is a sign of membrane damage induced by salt stress. Hussain et al (2022) investigated the salt tolerance of contrasting wheat genotypes and concluded that a lower MDA production in salt-tolerant varieties correlated with a lower-membrane lipid peroxidation [ 123 ]. Another study showed that the overexpression of the peroxidase gene GsPRX9 from wild-type soybean increased salt tolerance with a concomitant enhancement of the antioxidant response [ 124 ].…”

Soil salinization is a severe abiotic stress that negatively affects plant growth and development, leading to physiological abnormalities and ultimately threatening global food security. The condition arises from excessive salt accumulation in the soil, primarily due to anthropogenic activities such as irrigation, improper land uses, and overfertilization. The presence of Na⁺, Cl−, and other related ions in the soil above normal levels can disrupt plant cellular functions and lead to alterations in essential metabolic processes such as seed germination and photosynthesis, causing severe damage to plant tissues and even plant death in the worst circumstances. To counteract the effects of salt stress, plants have developed various mechanisms, including modulating ion homeostasis, ion compartmentalization and export, and the biosynthesis of osmoprotectants. Recent advances in genomic and proteomic technologies have enabled the identification of genes and proteins involved in plant salt-tolerance mechanisms. This review provides a short overview of the impact of salinity stress on plants and the underlying mechanisms of salt-stress tolerance, particularly the functions of salt-stress-responsive genes associated with these mechanisms. This review aims at summarizing recent advances in our understanding of salt-stress tolerance mechanisms, providing the key background knowledge for improving crops’ salt tolerance, which could contribute to the yield and quality enhancement in major crops grown under saline conditions or in arid and semiarid regions of the world.

“…The 200 mM salt stress was applied at three leaves stage and plantlets were exposed to salt stress for five delay time exposure 6 h, 12 h, 24 h, 48 h and 72 h along with control. The collection of plant samples/parts under control and salt stress condition complies with national, international and/or institutional guidelines in the present study 66 .…”

Abiotic stresses are a significant constraint to plant production globally. Identifying stress-related genes can aid in the development of stress-tolerant elite genotypes and facilitate trait and crop manipulation. The primary aim of this study was to conduct whole transcriptome analyses of the salt-tolerant faba bean genotype, Hassawi-2, under different durations of salt stress (6 h, 12 h, 24 h, 48 h, and 72 h) at the early vegetative stage, to better understand the molecular basis of salt tolerance. After de novo assembly, a total of 140,308 unigenes were obtained. The up-regulated differentially expressed genes (DEGs) were 2380, 2863, 3057, 3484, and 4820 at 6 h, 12 h, 24 h, 48 h, and 72 h of salt stress, respectively. Meanwhile, 1974, 3436, 2371, 3502, and 5958 genes were downregulated at 6 h, 12 h, 24 h, 48 h, and 72 h of salt stress, respectively. These DEGs encoded various regulatory and functional proteins, including kinases, plant hormone proteins, transcriptional factors (TFs) basic helix-loop-helix (bHLH), Myeloblastosis (MYB), and (WRKY), heat shock proteins (HSPs), late embryogenesis abundant (LEA) proteins, dehydrin, antioxidant enzymes, and aquaporin proteins. This suggests that the faba bean genome possesses an abundance of salinity resistance genes, which trigger different adaptive mechanisms under salt stress. Some selected DEGs validated the RNA sequencing results, thus confirming similar gene expression levels. This study represents the first transcriptome analysis of faba bean leaves subjected to salinity stress offering valuable insights into the mechanisms governing salt tolerance in faba bean during the vegetative stage. This comprehensive investigation enhances our understanding of precise gene regulatory mechanisms and holds promise for the development of novel salt-tolerant faba bean salt-tolerant cultivars.

“…For example, a recent study on A. tricolor foliage plants showed an elevated amount of SOD, ascorbate, and APX in a salttolerant variety (VA14) to assist ROS detoxification (Sarker and Oba, 2020). Hussain et al (2022) investigated the salt tolerance of contrasting wheat genotypes and concluded that a lower MDA production in salt-tolerant varieties correlated with a lower-membrane lipid peroxidation (Hussain et al, 2022). It is clear from Fig.…”

Nanoparticles have been widely used in agriculture in the past few years. The purpose of this work was to illustrate the potential of nanocellulose (NC) at different concentrations (0, 0.3%, and 0.6%) for priming wheat to enhance seed germination under different saline concentration (0.7, 5, 10, 15, and 20 dSm -1 ) and to investigate the impacts of NC seed priming treatments on growth, root morphology, water relation, Superoxidase enzyme (SOD) and nutrient influx under salt stress. Results indicated that salt stress decreased germination percent, root length, root surface area, and water content. Moreover, increased root radius, Na influx and SOD enzyme. Seed priming with NC at 0.3% was the best treatment in improving germination percent, root length, root surface area and Na influx. While seed priming with 0.6% was the most effective treatment in decreasing SOD enzyme. Overall, the results of this study showed that applying NC as a priming seed treatment can improve wheat germination and seedling growth while shielding the plants from the damaging effects of salinity stress.
