“…The current results are similar to the findings obtained by several investigations, Turki et al (2012) reported that the decline in grain yield could be caused by salinity, which caused photosynthetic ability to be decreased, leading to less synthesis of starch and grain accumulation. These results are in complete harmony with those obtained by (El-Saber et al, 2016 andYassin et al, 2019a) on barley and wheat under salinity stress conditions. Many studies confirm the reduction of yield and its components under saline stress conditions, which may be due to: 1) loss of spike-bearing tillers (Maas et al, 1996).…”

“…The accumulation of malondialdehyde under saline conditions is well documented by (Borzouei et al, 2012), who indicated that malondialdehyde content was higher in salt-sensitive wheat cultivar than salt-tolerant cultivar. In this connection, MDA release is one of the biochemical changes likely to be associated with adverse saline stress conditions and was used as a biomarker for assessing oxidative stress (El-Saber et al, 2016). A high concentration of MDA is associated with oxidative damage to the plant cell membranes in plant portions.…”

his investigation was applied to find out the seven bread wheat lines that are more tolerant to saline stress (6195 ppm soil and 8934 ppm irrigated water) at Ras Sudr, South Sinai, Egypt. Data indicated that bread wheat lines greatly varied in their ability to grow and subsequently assimilate and translocate biochemical components. Line1 (L1) surpassed the other lines, it was recorded the maximum values of growth, yield, and proline as well as the lowest malondialdehyde content followed by L3 and L7. ISSR-PCR analysis was used for discriminating between lines. A total of 102 DNA bands are detected across the six ISSR primers, out of which only 72 bands (51 non-unique bands and 21 unique bands) are polymorphic with polymorphism percentages (70.58%). In this regard, primer ISSR2 gave the highest polymorphism (92%) followed by ISSR-13 (86%) and ISSR-11 (78%). Also, patterns of proteins (SDS-PAGE) and superoxide dismutase (SOD) have been successfully used in discriminating between salt-tolerant and saltsensitive lines. Concerning SDS-PAGE, bands number in 7 wheat lines ranged from 13 to 14 with molecular weights ranging between 6 to 130 kDa, and the more intensive bands are presented at 25, 29, and 34 kDa. Moreover, SOD patterns indicated the presence of 5 bands; the major is presented at bands (No. 4 and 5) in all wheat lines. Based on the results obtained, L1 was the best wheat line followed by L3 and L7 which more tolerant to saline stress, and this was associated with increasing growth, yield, and proline as well as decreasing MDA content. In conclusion, SDS-PAGE, SOD, and ISSR analyses are useful biochemical and molecular tools to discriminate different bread wheat lines under saline conditions.

“…Salinity is conditions that occur mainly in arid and semiarid regions; it is one of the major abiotic stresses that adversely affect the crop productivity and quality [1,2,3,4]. Salinity affects almost all aspects of plant growth; it imposes ionic toxicity, osmotic stress, nutrient deficiency, and oxidative stress in plants, and therefore, limits the absorption of soil water [5].…”

This study aimed to investigate the effects of chitosan nanoparticles (C-NPs), spermine (Spm) as well as chitosan nanoparticles encapsulated spermine (C-Spm NPs) on growth, yield, chlorophyll, bioactive compounds, and capsaicinoids in chili pepper cv. Omiga F1 under saline stress conditions in Ras Sudr region, Egypt, in years 2020-2021. Data indicated that the exogenous application of C-NPs, Spm, and C-Spm NPs alleviated the adverse effect of salinity on chili pepper plants and enhanced growth, yield, chlorophyll content, antioxidant enzymes activity superoxide dismutase (SOD), and catalase (CAT). The maximum values of these parameters were recorded when plants treated with C-Spm NPs at 1.5 mM. For GC/MS analysis, data revealed the presence of 22 active compounds whereas, the maximum area percent were, 1-Tetradecanol(CAS), Phenol,2,4-bis(1,1dimethylethyl), 1-Heptadecene(CAS), 3-Eicosene,(E), (cis)2-nonadecene, and 5-Eicosene,(E). Regarding the capsaicinoids found in chili pepper, the main compounds identified among the capsaicinoids were capsaicin and dihydrocapsaicin. The maximum amount of capsaicin and dihydrocapsaicin were recorded when plants treated with C-Spm NPs at 0.5 mM. For the general taste of chili pepper, the Scoville heat unit (SHU) was calculated. Data indicated that plants treated with C-Spm NPs at 0.5 mM gave quite a high SHU related to higher contents of the capsaicinoids.

“…From the records in Table 4, it is evident that there was no significance in chlorophyll a, carotenoids, and total pigments between applications of MDA release is one of the biochemical changes likely to be associated with adverse saline stress conditions and is utilized as a biomarker for assessing oxidative stress. 43 A high concentration of MDA is associated with oxidative damage to the plant cell membranes in plant portions. Thus, it is used to determine the level of oxidative damage under stressful conditions like salt stress.…”

Effects of magnetite nanoparticles on physiological processes to alleviate salinity induced oxidative damage in wheat

et al. 2021

BACKGROUND: One of the major abiotic stressors that have a serious effect on plant growth and productivity worldwide is the salinity of soil or irrigation water. The effect of foliar application of magnetite nanoparticles (size = 22.05 nm) at different concentrations (0, 0.25, 0.5, and 1.0 ppm) was investigated to improve salinity tolerance in two wheat cultivars, namely, Misr1 (Tolerant) and Gimmeza11 (Sensitive). Moreover, toxicological investigations of magnetite oxide nanoparticle in Wistar albino rats were estimated. RESULTS:The magnetite nanoparticles positively affected growth, chlorophyll, and enzymatic antioxidants such as superoxide dismutase (SOD), stimulating reduced glutathione and improving the aggregation of several polypeptide chains that may be linked to the tolerance of saline stress. In contrast, magnetite nanoparticles reduced malondialdehyde (MDA). Inverse sequence-tagged repeat (ISTR) assay of DNA molecular marker showed the change in band numbers with the highest polymorphic bands with 90% polymorphism at primer F3, B5 and 20 positive bands in Gimmeza11 with 0.5 ppm magnetite nanoparticles. In the median lethal dose (LD 50 ) study, no rats died after the oral administration of magnetite nanoparticle at different doses. Therefore, the iron oxide nanoparticle was nontoxic when administered orally by gavage. CONCLUSION: Magnetite nanoparticles partially helped to alleviate the effects of salt stress by activating growth, chlorophyll content, SOD, glutathione, and soluble proteins in two wheat cultivars (Misr1 and Gimmeza11) and decreasing MDA content.
