“…Environmental stresses are important in EO production [35,36]. Our results revealed that moderate drought stress along with Si and S0-NPs enhanced EO yield, which con rmed the previous investigations with drought [37,38] or Si application [36]. The enhanced EO amount under slight drought stress may be attributed to the decline in leaf surface and enhancement of oil gland number and density [39].…”

Purpose Silicon (Si) plays beneficial role in alleviating biotic and abiotic stresses but comparative investigations with Si nanoparticles (Si-NPs) under water restriction on medicinal plants is not recognized. The aim of this study was to observe the Si and Si-NPs effects on growth, physio-chemical attributes, and essential oil (EO) profile in aerial parts of coriander (coriandrum sativum L.) under water stress. Methods A split-plot experiment was conducted with irrigation regimes (irrigation after 60, 90, and 120 mm evaporation from Class A pan) in the main plots and foliar application of Si (in the form of Na2SiO3) and Si-NPs in the subplots during 2019 and 2020. Results The results represented drought particularly severe stress decreased biological yield and relative water content (RWC) but increased total soluble sugar (TSS). Both Si and Si-NPs improved plant growth and yield through improved RWC, TSS, total phenolic content (TPC) and total flavonoid content (TFC). Moderate drought stress with Si-NPs was highly effective on TPC, TFC, EO percentage and yield. The main EO constitutes were n-Decanal (20.8-27.6%), 2E-Dodecanal (13.3-16.7%), 2E-Decanal (13.9-18.7%), 2E-Tridecen-1-al (7.3-10.5%), Dodecanal (7.2-10.6%), and n-Nonane (4.3-8.7%). Heat map analysis (HMA) showed foliar application of Si and Si-NPs were significantly distinguished from control treatment, which was mainly explained by EO yield and TFC attributes. Conclusion Foliar-applied Si-NPs was the rapidly and highly effective practice to reach the optimum antioxidant capacity and EO yield of coriander plants when experience moderate drought stress.

“…The supplemented SNP holds the potential to mitigate salt stress through the regularization of physiological (chlorophyll content, relative water content, electrolyte leakage, and stomatal behavior) [ 39 ] and biochemical (MDA, proline, phenolics, and antioxidant enzymes) attributes of plants [ 4 ]. Its role in coping with salinity stress has been well documented; however, its application in lentil crops for salt stress tolerance has not been studied previously.…”

Soil salinity disrupts the physiological and biochemical processes of crop plants and ultimately leads to compromising future food security. Sodium nitroprusside (SNP), a contributor to nitric oxide (NO), holds the potential to alleviate abiotic stress effects and boost tolerance in plants, whereas less information is available on its role in salt-stressed lentils. We examined the effect of exogenously applied SNP on salt-stressed lentil plants by monitoring plant growth and yield-related attributes, biochemistry of enzymes (superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD)) amassing of leaf malondialdehyde (MDA) and hydrogen peroxide (H2O2). Salinity stress was induced by NaCl application at concentrations of 50 mM (moderate salinity) and 100 mM (severe salinity), while it was alleviated by SNP application at concentrations of 50 µM and 100 µM. Salinity stress severely inhibited the length of roots and shoots, the relative water content, and the chlorophyll content of the leaves, the number of branches, pods, seeds, seed yield, and biomass per plant. In addition, MDA, H2O2 as well as SOD, CAT, and POD activities were increased with increasing salinity levels. Plants supplemented with SNP (100 µM) showed a significant improvement in the growth- and yield-contributing parameters, especially in plants grown under moderate salinity (50 mM NaCl). Essentially, the application of 100 µM SNP remained effective to rescue lentil plants under moderate salinity by regulating plant growth and biochemical pathways. Thus, the exogenous application of SNP could be developed as a useful strategy for improving the performance of lentil plants in salinity-prone environments.

“…In our study, similar results were detected in the droughtstressed seedlings (Figure 1b-e). Additionally, how a plant responds to stress not only entails changed photosynthesis but also the accumulation of osmolytes, such as soluble sugars and proline, which reflect the degree of injury [41]. We found that the content of soluble sugars and proline both enlarged as the drought stress continued (Figure 2c,d).…”

Drought stress can dramatically impair woody plant growth and restrict the geographical distribution of many tree species. To better understand the dynamics between the response and mechanism of Cupressus gigantea to drought and post-drought recovery, a comparative analysis was performed, relying on physiological measurements, RNA sequencing (RNA-Seq) and two-dimensional gel electrophoresis (2-DE) proteins. In this study, the analyses revealed that photosynthesis was seriously inhibited, while osmolyte contents, antioxidant enzyme activity and non-enzymatic antioxidant contents were all increased under drought stress in seedlings. Re-watering led to a recovery in most of the parameters analyzed, mainly the photosynthetic parameters and osmolyte contents. Transcriptomic and proteomic profiling suggested that most of the differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) were specifically altered, and a few were consistently altered. Drought induced a common reduction in the level of DEGs and DEPs associated with photosynthesis. Notably, DEGs and DEPs involved in reactive oxygen species (ROS) scavenging, such as ascorbate oxidase and superoxide dismutase (SOD), showed an inverse pattern under desiccation. This study may improve our understanding of the underlying molecular mechanisms of drought resistance in C. gigantea and paves the way for more detailed molecular analysis of the candidate genes.
