Summary: This study highlights the role of salt priming in mitigating salt stress on faba bean. It was found that salt shock resulted in negative effects on growth, photosynthetic pigments, and yield, accompanied by increased generation of H2O2 and lipid peroxidation. However, priming with increasing concentrations of NaCl improved plant defense mechanisms, including enhanced expression of GSH-related genes, proline accumulation, and antioxidant enzymes, thereby reducing the detrimental effects of salt shock on growth and yield.

Summary: This study evaluated salt tolerance in common vetch collections and investigated the underlying physiological mechanisms. The results showed that salt-tolerant collections of common vetch maintained lower levels of Na+ and higher levels of K+ and K+/Na+ ratio under salt stress compared to salt-sensitive ones. The expression of genes involved in Na+ and K+ transportation and redistribution was responsible for salt stress. Transcript levels of NHX7, HKT1, AKT2, and HAK17 were induced after salt stress, with higher levels in salt-tolerant collections. Proline accumulation and antioxidant defense system were also promoted in salt-tolerant collection. These findings suggest that salt tolerance in common vetch is associated with the maintenance of ion homeostasis, gene expression, proline accumulation, and antioxidant defense system.

Summary: Environmental factors can affect crop production, with seawater stress leading to decreases in growth, chlorophyll concentrations, mineral elements content, and yield of faba bean plants. However, the combined application of proline and salicylic acid under seawater stress conditions significantly improved most of the studied characteristics.

Summary: This study investigated the effects of sodium nitroprusside (SNP) on the growth performance and productivity of two cultivars of faba bean. The results showed that SNP had different effects on the two cultivars, improving growth and yield in one and showing good performance at a lower concentration in the other. SNP also affected the photosynthetic pigments, proline content, and hydrogen peroxide levels. The findings suggest that foliar application of SNP can improve crop growth and productivity by modulating oxidant and antioxidant systems.

Summary: This study used a nitrogen-fixing bacteria strain to synthesize silver nanoparticles for controlling bean yellow mosaic virus in faba bean plants. The AgNPs induced plant resistance, reduced disease severity and virus concentration levels, and enhanced plant health by raising photosynthetic rates and increasing plant weight. The AgNPs also inhibited the development of the virus and decreased oxidative stress markers in the plants.

Summary: This study aimed to investigate the morphological and physiological responses of tomato seedlings under salt stress and the application of thermally treated carbon nanoparticles of oil fly ash (COFA). The results showed that salt stress significantly reduced the growth and photosynthetic pigments of tomato plants, but the application of carbon nanoparticles promoted the growth conditions and photosynthetic pigments. Furthermore, the carbon nanoparticles enhanced the antioxidant defense systems and salt tolerance of tomato seedlings.

Summary: The study identified different faba bean genotypes with varying levels of frost resistance, with early and mid-season sowings being more susceptible to frost damage, while late sowings could reduce the impact. Additionally, flowers formed at the beginning of flowering had a faster and higher pod formation rate, contributing significantly to yields. Frost-tolerant genotypes and faster pod formation rates identified in this study could be utilized in breeding better varieties in the future.

Summary: This study evaluated faba bean genotypes in response to saline stress and identified tolerant genotypes. The results showed that phenotypic variability among faba bean genotypes was limited under salinity stress conditions. The study also found significant associations between the number of seeds/plants and plant height, stomatal conductance, days to flowering, the number of pods, and seed weight. However, there was no significant association with leaf temperature, fresh weight, Na+, K+, and Na/K ratio.

Summary: The foliar application of salicylic acid has been shown to improve sorghum growth under saline conditions by regulating plant metabolism and antioxidant capacity. A concentration of 150 mg/L of salicylic acid was found to be most effective for alleviating the adverse effects of salt stress, while a concentration of 100 mg/L was most effective for improving sorghum growth under non-saline conditions.

Summary: Legumes are sensitive to salt stress, especially in the early stages of growth. Exogenous application of brassinosteroids (BRs) or proline (Pro) can improve salt stress tolerance in legume plants. This study conducted pot experiments to investigate the roles of BRs or Pro in improving salt tolerance in snap beans. The results showed that BRs or Pro reduced the uptake and translocation of Na+ and Cl-, enhanced K+ assimilation, and improved water status, chlorophyll content, and antioxidant enzyme activity, thereby enhancing salt tolerance in snap beans.

Summary: The cotton leaf worm is a destructive agricultural pest in Egypt, and chemical pesticides have led to environmental pollution. Six soybean genotypes were studied under natural infection with the pest, and treatment with methyl jasmonate and sodium nitroprusside was found to enhance resistance and increase secondary metabolites and antioxidants in the plants. MeJA was more effective than SNP in enhancing the resistance of susceptible genotypes.

Summary: The study showed that pre-treating sunflower seeds with Chenopodium album extract and gamma radiation significantly reduced the incidence of fusarium root rot and enhanced the plant's resistance to the pathogen. Furthermore, treated plants showed significant increases in various physiological and biochemical parameters, along with a decrease in H2O2 content and lipid peroxidation. The treatment also resulted in changes in fatty acid composition, with a decrease in unsaturated fatty acids in irradiated plants and an increase in unsaturated fatty acids in plants treated with C. album extract.

Summary: A study was conducted to find an alternative to synthetic fungicides for controlling Rhizoctonia solani damping off in common bean. The combination of seed presoaking in Vitex agnus-castus essential oils and foliar spray with ZnO NPs was found to be more effective in reducing disease incidence and enhancing seed germination percentage, compared to individual treatments. Additionally, plants treated with the combination showed higher levels of enzymatic and non-enzymatic antioxidants, as well as mineral composition, compared to untreated infected plants.
