“…Usually, plants resist salt stress by synthesis of certain organic compatible solutes that can help plants to survive extremist osmotic stress as soluble sugars because of their osmoprotectant properties (Negrao et al, 2017;Nemat Alla et al, 2020). The present investigation showed similar rises in soluble sugars.…”

“…Thus, the decrease of K concomitant with the elevated Na level in the present results could confirm nutrient imbalances or even deficiencies. In this respect, salt stress lowered K and K/ Na ratio (D'Amelia et al, 2018;Nemat Alla et al, 2020). Moreover, the increased K/Na ratio is related with the plant salinity stress tolerance (Kordrostami et al, 2017).…”

“…Salinity can inhibit plant growth via altering the water potential, imbalance of ions, impairing of both cell division and expansion in addition to production of ROS causing oxidative damage (Tuteja et al, 2009;Nemat Alla et al, 2020). Elevated Na + level lowers the concentrations of the other cations in the plant, can disrupt the plant cationic balance (Acosta-Motos et al, 2017).…”

“…In the present study, H 2 O 2 and MDA exhibited vast enhancement while CAT and APX activities were inhibited. CAT can scavenge H 2 O 2 and APX can dismutase H 2 O 2 to water and molecular oxygen using AsA as a vital electron source (Van Doorn & Ketsa, 2014;Nemat Alla et al, 2020). Therefore, the inhibited activities of CAT and APX would cause less efficient detoxification of H 2 O 2 detoxification leading so to be accumulated with a concomitant increase in oxidative stress.…”

“…Due to salinity conditions, reactive oxygen species (ROS) are overproduced leading to oxidative stress, a state that has impacts to metabolism. It destroys proteins, lipids, and nucleic acids (Tuteja et al, 2009;Nemat Alla et al, 2020;Safwat & Abdel Salam, 2022). Plant have an array of antioxidant defense to prevent the formation of ROS or to limit their damaging effects (Nemat Alla & Hassan, 2006;Tuteja et al, 2009) either enzymatically or nonenzymatically (Azevedo Neto et al, 2006).…”

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ 41 T HIS WORK aims at enhancing soybean growth and fatty acid composition of oil yield when grown under salinity by seed priming in AsA. Treatment of 10-day-old soybean seedlings with NaCl at 100 or 200 mM for 11 days significantly lowered K + , K + /Na + ratio and ascorbate (AsA) and inhibited the activities of catalase (CAT) and ascorbate peroxidase (APX), contrarily elevated Na + , soluble sugars, MDA and H 2 O 2 . Meanwhile, total fatty acids were lowered in the yielded oil of mature seeds (115 days after sowing) concurrent with decreases in unsaturated fatty acids but increased saturated fatty acids (particularly palmitic and stearic). Nonetheless, seed priming in AsA improved growth coincided with raised K + , K + /Na + ratio and AsA as well as CAT and APX activities concomitantly with retractions in the accumulated Na + , osmolytes and oxidative stress indices. Besides, saturated fatty acids were decreased but unsaturated fatty acids were increased synchronized with rises in total pool. This finding suggests the alleviation of salinity by priming in AsA through enhancing osmoprotection and antioxidants in addition to improving oil quality particularly omega fatty acids.

Selenium (Se) plays an important role in geochemistry and is an essential trace element for humans and animals. This review summarizes the transformation and accumulation of Se in the plant-soil-microbe system. As one of the important reservoirs of Se, soil is an important material basis of its entry into the food chain through plants. Soil with an appropriate amount of Se is beneficial for plant growth and plays a valuable role in a stress-resistant environment. Among the many migration and transformation pathways, the transformation of Se by microorganisms is particularly important and is the main form of Se transformation in the soil environment. In this review, the role and form transformation of Se in plants, soil, and microorganisms; the role of Se in plants; the form, input, and output of Se in soil; the absorption and transformation of Se by plants; and the role of microorganisms in Se transformation are presented. In addition to describing the migration and transformation laws of Se in the environment, this review expounds on the main directions and trends of Se research in the agricultural field as well as current gaps and difficulties in Se-related research. Overall, this reviews aims to provide necessary information and theoretical references for the development of Se-rich agriculture.

AimsSelenium (Se) has been reported to mitigate the harmful effect of salt stress on plants, however the internal mechanisms are still unknown. Here, the effects of Se supplementation on tomato under salt stress were investigated. MethodsThe biomass, relative electrical conductivity (REC), relative water content (RWC), malondialdehyde (MDA), soluble sugar and proline content, and the regulation of plant hormones of Se application in tomato were investigated after exposure to Se and salt stress treatments. ResultsExogenous Se application improved photosynthesis and the water use e ciency (WUE) of tomato plants under salt stress, thereby promoting the growth of tomato plants under salt stress. Se supplementation also reduced the REC and MDA, decreased the content of H 2 O 2 and O 2•− , and mitigated the oxidative damage caused by salt stress. Exogenous Se increased the salicylic acid (SA) content in tomato leaves and roots via up-regulating the PAL or ICS pathways of SA biosynthesis. After pretreatment with the SA inhibitor (ABT), the photosynthetic e ciency of tomato plants decreased, the growth was weakened, and the relative electrical conductivity was increased, indicating that the alleviating role of Se on salt stress was abolished. ConclusionsOur results clari ed the roles of Se and its regulation mechanisms in plant salt stress tolerance, as well as the critical involvement of SA in this process. The study of Se in plant abiotic stress tolerance will give more theoretical foundation for the usage of exogenous Se in agricultural production to enhance the crop growth and yield under adversity stresses.
