Summary: This study investigates the effect of salicylic acid (SA) on vanadium (V) stress tolerance in rice seedlings. The results show that SA pretreatment improves the growth of rice seedlings by enhancing chlorophyll content, photosynthetic assimilation, and antioxidant enzyme activities. SA also regulates the expression of genes related to antioxidant enzymes and glyoxalase, reducing the accumulation of V and methylglyoxal and enhancing the stress resistance of rice seedlings.

Summary: Foliar application of salicylic acid improves salt tolerance of fenugreek plants by increasing chlorophyll content index and reducing malondialdehyde content, while promoting accumulation of proline, total phenolics, and flavonoids. Additionally, it enhances total free amino acids and shikimic acid, and activates antioxidant enzymes such as ascorbate peroxidase, peroxidase, polyphenol oxidase, and catalase.

Summary: Breeding chilling-resistant corn and using exogenous hormones to alleviate stress damage are crucial for successful corn farming. In this study, we evaluated the germination rate and chilling resistance level of 45 corn varieties, and investigated the effect of salicylic acid (SA) treatment on corn plants under cold stress. Our findings demonstrated that most cold-treated corn varieties had lower germination energy, germination percentage, and germination index compared to the control group. We also found that SA treatment enhanced chilling resistance in both chilling-resistant and chilling-sensitive corn varieties.

Summary: This study evaluated the role of exogenously applied salicylic acid (SA) in ameliorating oxidative damage caused by the herbicide mesosulfuron-methyl + iodosulfuron-methyl in wheat plants. The results showed that SA pre-treatment reduced the herbicide-induced physiological damage by regulating enzymatic antioxidants and decreasing the contents of hydrogen peroxide and malondialdehyde.

Summary: Low-temperature storage significantly affects the mango fruit, causing chilling injury. This study investigated the molecular and biochemical changes in mango cv. Alphonso fruits during low-temperature storage. The results showed increased free radical generation, lipid peroxidation, and protein carbonylation, as well as reduced unsaturated fatty acid content and membrane leakage in the fruits stored at 5 degrees C compared to control and temperature gradient storage (TGS). Gene expression analysis suggested the involvement of fatty acid desaturase, peroxidase, and glutathione reductase in cold stress-induced membrane changes. Furthermore, TGS treatment effectively reduced chilling injury by increasing unsaturated fatty acids and reducing lipid peroxidation and protein carbonylation.

Summary: Melatonin (MT) at a concentration of 0.05 mM showed potential in alleviating chilling injury (CI) in ‘Xuxiang’ kiwifruit during storage at 1°C for 90 days. The pretreatment of MT stimulated the generation of endogenous salicylic acid (SA) and enhanced the defense response and antioxidative protection of kiwifruit against chilling stress. However, the positive effects of MT were counteracted when combined with paclobutrazol PAC, a SA biosynthesis inhibitor.

Summary: Ethylene regulates the response of tomato fruit to chilling stress by affecting hormone and protein expression, and can reduce or intensify cold injury in tomato fruit through ethephon or 1-methylcyclopropene treatment. This study suggests a new regulatory pathway where ethylene enhances tolerance to chilling stress in tomato fruit by synergistically regulating antioxidant enzymes and ATP synthases.

Summary: Research has shown that using cyanobacteria, such as Arthrospira platensis, Desmonostoc muscorum, and Anabaena oryzae, through foliar spraying is an effective approach to induce immunity against Fusarium wilt in Capsicum annuum L. These cyanobacterial extracts significantly reduced the risk of infection and improved plant growth, metabolic characteristics, and phenol levels. The application of cyanobacteria also enhanced the activity of antioxidant enzymes and altered the endogenous hormone content in the infected plants.

Summary: Transcriptome analysis revealed that Mangifera indica L. cv. Keitt responds to chilling stress by enhancing photosynthetic pigment content and antioxidant enzyme activity. After 3 hours of chilling, 410 genes showed differential expression, with WRKY70 and PLD1 significantly up-regulated after 9 hours. Compared to 9 and 0 hours, there were 1123 differentially expressed genes (DEGs). DEGs were enriched in hormonal signal transduction, secondary metabolites, and the abiotic stress response. This study will contribute to the development of chill-resistant mangoes.

Summary: This study focuses on the synthesis of a proton exchange membrane for microbial fuel cells (MFCs) that can simultaneously produce bioelectricity and treat domestic wastewater. The membrane was prepared through ionizing irradiation-induced graft copolymerization and sulfonation processes. The prepared membranes were characterized for their structural, thermal, mechanical, and electrical properties, as well as physicochemical characteristics. The results confirmed the successful preparation of a suitable membrane for the proposed application. Additionally, the performance of the assembled MFC was thoroughly investigated, including its electrochemical behavior and wastewater treatment capability. The study found that the sulfonated LDPE-g-P(GMA-co-VAc) membrane with an 80% grafting degree showed substantial removal of chemical oxygen demand and had promising power density.

Summary: In this study, the synthesis of zinc oxide nanoparticles (ZnO NPs) was described and the impact of alginate-based ZnO NPs (Alg-ZnO NPs) on the microbiological activity, storage behavior, and physico-chemical properties of 'Kiett' mango fruit was evaluated. The Alg-ZnO NPs exhibited inhibition capacities against the growth of E. coli and S. aureus bacteria. Coating the fruits with Alg-ZnO NPs maintained better fruit quality, controlled decay incidence, and increased the shelf life of the mango fruits.

Summary: Glycidyl Methacrylate (GMA) was grafted onto Polycarbonate (PC) using a radiation-induced grafting technique, followed by amination and quaternization to synthesize Q[A(PC-g-PGMA)]. The effects of total concentration, monomer concentration, and absorbed dosage on the degree of grafting (DG) were studied. The structure of the resultant Q[A(PC-g-PGMA)] was characterized using FTIR, SEM, and TGA. Q[A(PC-g-PGMA)] was used in a batch procedure to investigate the sorption efficiency of I-131 in varied concentrations of HCl and/or HNO3 solutions. The thermodynamic parameters indicated that the sorption process of I-131 was endothermic and spontaneous.

Summary: One way to help plants cope with unfavorable temperatures is by grafting elite cultivars onto adaptable rootstocks. A study was conducted to evaluate the response of two rootstocks, Citrus volkameriana (Volkamer) and Citrus macrophylla (Alemow), along with the cultivars 'Olinda Valencia orange' and 'Murcott Tangerine' grafted onto them, to chilling stress. The results showed that grafting onto Volkamer improved the physiological, biochemical, and anatomical responses of the scions to low-night temperature stress compared with grafting onto Alemow.

Summary: Chilling stress in Egypt reduces the productivity of banana crops, but pre-treatment with ABA can enhance the tolerance of banana shoots to chilling stress. ABA treatment keeps cell membranes stable, decreases ion leakage and lipid peroxidation, maintains photosynthetic pigment concentration, increases accumulation of soluble carbohydrates and proline, and enhances antioxidant enzyme activity, thus protecting banana shoots from chilling stress damage.

Summary: The aim of this study was to assess the phenotypic diversity among four date palm male genotypes, and the results showed significant differences in morphological parameters between these genotypes. Most of the selected morphological parameters could be used as quantitative markers for the identification of date palm male genotypes. Principal component analysis revealed that the studied parameters formed two major homogeneous groups, which accounted for a high proportion of the observed phenotypic diversity. Cluster analysis showed that Fardh, Ghannami Ahmer, and Meghal are more closely related to each other than Hayani, and the lowest similarity was found between Hayani and Ghannami Ahmer.
