“…The present study revealed that Ni accumulation in pepper seedlings not only interferes with mineral nutrient intake, but also impairs nutrient element transfer from root to shoot. These findings were consistent with prior studies on watermelon, lettuce, coriander, and cucumber ( Matraszek et al, 2017 ; Nawaz et al, 2018 ; Cao et al, 2019 ; Sardar et al, 2022b ).…”

Globally, heavy metal pollution of soil has remained a problem for food security and human health, having a significant impact on crop productivity. In agricultural environments, nickel (Ni) is becoming a hazardous element. The present study was performed to characterize the toxicity symptoms of Ni in pepper seedlings exposed to different concentrations of Ni. Four-week-old pepper seedlings were grown under hydroponic conditions using seven Ni concentrations (0, 10, 20, 30, 50, 75, and 100 mg L–1 NiCl2. 6H2O). The Ni toxicity showed symptoms, such as chlorosis of young leaves. Excess Ni reduced growth and biomass production, root morphology, gas exchange elements, pigment molecules, and photosystem function. The growth tolerance index (GTI) was reduced by 88-, 75-, 60-, 45-, 30-, and 19% in plants against 10, 20, 30, 50, 75, and 100 mg L–1 Ni, respectively. Higher Ni concentrations enhanced antioxidant enzyme activity, ROS accumulation, membrane integrity [malondialdehyde (MDA) and electrolyte leakage (EL)], and metabolites (proline, soluble sugars, total phenols, and flavonoids) in pepper leaves. Furthermore, increased Ni supply enhanced the Ni content in pepper’s leaves and roots, but declined nitrogen (N), potassium (K), and phosphorus (P) levels dramatically. The translocation of Ni from root to shoot increased from 0.339 to 0.715 after being treated with 10–100 mg L–1 Ni. The uptake of Ni in roots was reported to be higher than that in shoots. Generally, all Ni levels had a detrimental impact on enzyme activity and led to cell death in pepper seedlings. However, the present investigation revealed that Ni ≥ 30 mg L–1 lead to a deleterious impact on pepper seedlings. In the future, research is needed to further explore the mechanism and gene expression involved in cell death caused by Ni toxicity in pepper plants.

“…Lack et al 2013). Sardar et al (2022) also observed that SeNPs treatment increased proline content both in control and Cd-stressed plants. It appears that the SeNPs enhanced the proline synthesis through improving the activity of nitrate reductase required for the synthesis of proline(Subramanyam et al 2019).Soluble sugars as vital metabolic substrates, have a critical role in controlling numerous developmental phases of plants(Afzal et al 2021).…”

Much research has been carried out in agriculture and physiology to minimize the adverse effects of salinity on crops. This study was conducted to investigate the effect of selenium nanoparticles and plant growth-promoting bacteria (PGPRs) pretreatment on increasing the resistance of foxtail millet to salinity stress. Experimental treatments consisted of selenium nanoparticles at a concentration of 1 mg L-1, Bacillus cereus and Pseudomonas fluorescens and three different levels of saline solution with concentrations of 0, 100 and 200mM sodium chloride. In this study, foxmillet seeds were primming with solutions of selenium nanoparticles, a variety of bacteria and a mixture of both, and then the pretreated seeds were planted in pots and after two weeks were affected by salinity stress. After 10 days of salinity stress, plants were harvested for analysis. The results of measuring the growth, biochemical and physiological parameters of this study showed that soaking millet seeds in a solution of selenium nanoparticles can increase the plant's ability to cope with salinity stress by increasing photosynthetic pigments, compatible solutes, reducing oxidative stress, protecting the cell membrane and reducing sodium uptake, and it has more effects in the presence of PGPRs bacteria (such as Bacillus cereus and Pseudomonas fluorescens). Therefore, it is suggested that these two biostimulators be used together for greater effects. In addition, since most of the positive functions of these bacteria were not affected by salinity stress, so this type of bacteria can be used with selenium in saline soils.

“…The results of Ghasemian et al [ 65 ] supported our findings on the use of SeNPs in foliar spray to determine total proline content. Sardar et al [ 66 ] reported that plants raised from seeds primed with SeNPs exhibited enhanced proline and soluble sugar contents. The current study supported the findings of prior research [ 24 , 61 , 67 ].…”

In this study, selenium nanoparticles (SeNPs) and cerium oxide nanoparticles (CeONPs) were synthesized by using the extract of Melia azedarach leaves, and Acorus calamusas rhizomes, respectively, and investigated for the biological and sustainable control of yellow, or stripe rust, disease in wheat. The green synthesized NPs were characterized by UV-Visible spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and X-ray diffraction (XRD).The SeNPs and CeONPs, with different concentrations (i.e., 10, 20, 30, and 40 mg/L), were exogenously applied to wheat infected with Puccinia striformis. SeNPs and CeONPs, at a concentration of 30 mg/L, were found to be the most suitable concentrations, which reduced the disease severity and enhanced the morphological (plant height, root length, shoot length, leaf length, and ear length), physiological (chlorophyll and membrane stability index), biochemical (proline, phenolics and flavonoids) and antioxidant (SOD and POD) parameters. The antioxidant activity of SeNPs and CeONPs was also measured. For this purpose, different concentrations (50, 100, 150, 200 and 400 ppm) of both SeNPs and CeONPs were used. The concentration of 400 ppm most promoted the DPPH, ABTS and reducing power activity of both SeNPs and CeONPs. This study is considered the first biocompatible approach to evaluate the potential of green synthesized SeNPs and CeONPs to improve the health of yellow, or stripe rust, infected wheat plants and to provide an effective management strategy to inhibit the growth of Puccinia striformis.
