“…Plant growth and development of snap bean plants can be seriously affected under saline conditions [ 36 , 37 , 38 ]. In this study, we observed that exposed plants to salt stress led to an obvious and significant ( p ≤ 0.05) inhibition in their growth rate as a result of reducing the fresh ad dry weight of the shoot and root systems.…”

Although the effect of folic acid (FA) and its derivatives (folates) have been extensively studied in humans and animals, their effects are still unclear in most plant species, specifically under various abiotic stress conditions. Here, the impact of FA as a foliar application at 0, 0.1, and 0.2 mM was studied on snap bean seedlings grown under non-saline and salinity stress (50 mM NaCl) conditions. The results indicated that under salinity stress, FA-treated plants revealed a significant (p ≤ 0.05) increase in growth parameters (fresh and dry weight of shoot and root). A similar trend was observed in chlorophyll (Chl b), total chlorophyll, carotenoids, leaf relative water content (RWC), proline, free amino acids (FAA), soluble sugars, cell membrane stability index (CMSI), and K, Ca, and K/Na ratio compared to the untreated plants. In contrast, a significant decrease was observed in Na and salinity-induced oxidative damage as indicated by reduced H2O2 production (using biochemical and histochemical detection methods) and rate of lipid peroxidation (malondialdehyde; MDA). This enhancement was correlated by increasing the activities of antioxidant enzymes, i.e., superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (G-POX), and ascorbate peroxidase (APX). Gene expression analyses conducted using qRT-PCR demonstrated that genes coding for the Na+/H+ antiporter protein Salt Overly Sensitive 1 (SOS1), the tonoplast-localized Na+/H+ antiporter protein (NHX1), and the multifunctional osmotic protective protein (Osmotin) were significantly up-regulated in the FA-treated plants under both saline and non-saline treatments. Generally, treatment with 0.2 mM FA was more potent than 0.1 mM and can be recommended to improve snap bean tolerance to salinity stress.

“…As severe environmental abiotic stress that extends all over the world, salinity prevents plants from achieving their full physiological, biochemical, and genetic potential, resulting in disturbances to their growth, development, and productivity based on the severity and duration of exposure to stress conditions of salinity ( Torche et al, 2018 , Desoky et al, 2019 ). As a response to salt stress, in our study, the genotypes of tomatoes demonstrated less or more relative tolerance based on local varieties or wild lines.…”

“…As a response to salt stress, in our study, the genotypes of tomatoes demonstrated less or more relative tolerance based on local varieties or wild lines. This is due to a complex mixture of phenological, physiological and biochemical responses, which were expressed by a relative reduction in growth and growth-related indices and relative increased production of low-molecular-mass and enymatic antioxidant defense system, causing economic losses ( Torche et al, 2018 ).…”

Salinity is a major global problem that threatens the agricultural sector, especially in areas that suffer from a shortage of water. It motivates ionic toxicity, osmotic and oxidative stresses, which greatly inhibits plant performances and crop productivites. However, micronutrients (MNs) or plant extracts, like germinated maize grain extract (gMGE), have been reported to minimize the effects of salt stress on plant growth and returns. Therefore, this study aimed at evaluating the influences of MNs or gMGE applied as foliar sprays on growth, physio-biochemical indices, and antioxidative system components in three genotypes of tomato plants stressed by 9 dS m −1 NaCl. This salinity level markedly increased Na + content, lipid peroxidation, ion leakage, and markers related to oxidative stress (superoxide; O 2 •− and hydrogen peroxide; H 2 O 2 ). Besides, marked increases in activities of enzymatic (especially different forms of superoxide dismutase; SODs) and non-enzymatic antioxidants and osmoprotectant compounds were also observed. In contrast, growth, photosynthetic capacity including hill reaction activity (HRA), K + /Na + ratio, tissue cell integrity (e.g., cell water content and membrane stability), and K + and MNs contents decreased significantly under stress. However, compared to MNs, gMGE significantly improved the activities of the antioxidative system components (particularly SODs) and osmoprotectants, which were reflected in reduced Na + accumulation, lipid peroxidation, ion leakage, and oxidative stress. These results were coupled with remarkable elevations in photosynthetic capacity including HRA, K + /Na + ratio, tissue cell integrity, K + content, and MNs contents, all of which were reflected in the enhancement of plant growth. Compared to local tomato cultivars (e.g., Castle Rock and C10), the wild line “0043-1” had better results. The interaction of three factors; salt stress, promoters, and tomato genotypes was significant. The wild tomato line “0043-1” as the best salt-tolerant is a good candidate for implication in breeding programs for tolerance to salinity to produce salt-tolerant cultivars for use to maximize tomato growth and productivity in saline environments.

“…Presently, there is no finite test benchmark in salinity studies of legumes. However, chickpea (25 to 60 mM NaCl) [ 43 , 44 , 45 , 46 ], soybean (50 to 150 mM NaCl) [ 47 , 48 ], common bean (30 to 100 mM NaCl) [ 30 , 31 , 32 , 33 ] and a basic mungbean salt test dose was previously reported at 50 and 75 mM NaCl [ 34 ]. We utilized 50 mM NaCl as our test dose threshold for mungbean salinity germination test according to Chung et al (2016) [ 37 ].…”

“…Rabbie G.H (2005) reported that arbuscular mycorrhizal fungi encourage growth of mungbean under salinity as compared to kinetic hormones [ 28 ]. When comparing mungbean to common bean, the salinity threshold levels of common beans are between the ranges of 30 to 100 mM NaCl [ 30 , 31 , 32 , 33 ]. A suitable mungbean salt test threshold was reported to be at 50 and 75 mM NaCl [ 34 ].…”

Mungbean (Vigna radiata (L.) R. Wilzeck var. radiata) is a protein-rich short-duration legume that fits well as a rotation crop into major cereal production systems of East and South-East Asia. Salinity stress in arid areas affects mungbean, being more of a glycophyte than cereals. A significant portion of the global arable land is either salt or sodium affected. Thus, studies to understand and improve salt-stress tolerance are imminent. Here, we conducted a genome-wide association study (GWAS) to mine genomic loci underlying salt-stress tolerance during seed germination of mungbean. The World Vegetable Center (WorldVeg) mungbean minicore collection representing the diversity of mungbean germplasm was utilized as the study panel and variation for salt stress tolerance was found in this germplasm collection. The germplasm panel was classed into two agro-climatic groups and showed significant differences in their germination abilities under salt stress. A total of 5288 SNP markers obtained through genotyping-by-sequencing (GBS) were used to mine alleles associated with salt stress tolerance. Associated SNPs were identified on chromosomes 7 and 9. The associated region at chromosome 7 (position 2,696,072 to 2,809,200 bp) contains the gene Vradi07g01630, which was annotated as the ammonium transport protein (AMT). The associated region in chromosome 9 (position 19,390,227 bp to 20,321,817 bp) contained the genes Vradi09g09510 and Vradi09g09600, annotated as OsGrx_S16-glutaredoxin subgroup II and dnaJ domain proteins respectively. These proteins were reported to have functions related to salt-stress tolerance.
