“…The duration and concentrations of HT and PAG were selected according to the work of Li et al [ 44 ] for maize plants exposed to high temperatures. A dose of 1 mmol L −1 GSH was used for mung bean [ 30 ] and soybean [ 45 ] under saline stress. These concentrations were selected for pepper plants in the present experiment.…”

The aim of this study is to assess the role of L-cysteine desulfhydrase (L-DES) and endogenous hydrogen sulfide (H2S) in glutathione (GSH)-induced tolerance to salinity stress (SS) in sweet pepper (Capsicum annuum L.). Two weeks after germination, before initiating SS, half of the pepper seedlings were retained for 12 h in a liquid solution containing H2S scavenger, hypotaurine (HT), or the L-DES inhibitor DL-propargylglycine (PAG). The seedlings were then exposed for three weeks to control or SS (100 mmol L−1 NaCl) and supplemented with or without GSH or GSH+NaHS (sodium hydrosulfide, H2S donor). Salinity suppressed dry biomass, leaf water potential, chlorophyll contents, maximum quantum efficiency, ascorbate, and the activities of dehydroascorbate reductase, monodehydroascorbate reductase, and glyoxalase II in plants. Contrarily, it enhanced the accumulation of hydrogen peroxide, malondialdehyde, methylglyoxal, electrolyte leakage, proline, GSH, the activities of glutathione reductase, peroxidase, catalase, superoxide dismutase, ascorbate peroxidase, glyoxalase I, and L-DES, as well as endogenous H2S content. Salinity enhanced leaf Na+ but reduced K+; however, the reverse was true with GSH application. Overall, the treatments, GSH and GSH+NaHS, effectively reversed the oxidative stress and upregulated salt tolerance in pepper plants by controlling the activities of the AsA-GSH and glyoxalase-system-related enzymes as well as the levels of osmolytes.

“…The alleviated toxicity sign of nSe of 20 mg l -1 by NO may be partially attributed to the dramatic increases in the peroxidase activity, a crucial antioxidant enzyme. In plants, Se-induced antioxidant system has been regarded as a main mechanism contribute to its protective roles against various abiotic stress conditions (Feng et al, 2013;Ardebili et al, 2014;Ardebili et al, 2015).…”

“…Otherwise, it seems to be a benefit for many plants, especially hyper-accumulators (El-Ramady et al, 2016). Thus, the functional significance of Se may lead to enhance plant growth, modify cellular physiology, and/or improve plant resistance to abiotic and biotic stress conditions (Ardebili et al, 2014;Ardebili et al, 2015;El-Ramady et al, 2016).…”

Taking account of nano-compounds and biofortification, this research was conducted to evaluate peppermint (Mentha x piperita L.) responses to nano-selenium (nSe; 0, 2, and 20 mg l-1) and/or nitric oxide (NO; 0 and 8 mg l-1). Significant increases in leaf length, and area, and shoot fresh mass were enhanced by the low level of nSe and/or NO, contrasted with the high dose. The inhibitory effects of the high dose of nSe on the growth-related characteristics were significantly mitigated by NO. The adverse impact of nSe20 on chlorophyll concentration was alleviated by NO. The individual and combined treatments of nSe2 led to the significant inductions in the activities of nitrate reductase and peroxidase, whereas nSe20 inhibited. The proline contents in the nSe and/or NO-treated plants were higher than in the control. The nSe and/or NO provoked stimulation in activities of phenylalanine ammonia lyase enzyme. The foliar applications of nSe and/or NO triggered the accumulations of soluble phenols. Interestingly, the toxicity of nSe at the high dose led to the severe cell destruction in the cortex layer of the basal stem, which was partially alleviated by NO. The simultaneous applications of these supplements may consider as an alternative strategy for fortifying and improving plant protection, regarding sustainable agriculture.

“…Selenium at low concentrations exerts positive effects for plants such as promoting growth, increasing antioxidative capacity, improving yield and quality, and delaying ripening and senescence (Hartikainen et al, 2000; Xue et al, 2001; Turakainen et al, 2004; Broadley et al, 2010; Pukacka et al, 2011; Pezzarossa et al, 2012). Applying Se fertilizer as base fertilizer or foliar spray has been used to increase the Se content in the edible portion of crops and to simultaneously counteract the detrimental effects of diverse environmental stresses, such as heavy metals, water, drought, salt, high temperature, UV radiation, senescence, pathogens, and insect pests (Hartikainen et al, 2000; Pennanen et al, 2002; Hanson et al, 2003; Djanaguiraman et al, 2005, 2010; Germ et al, 2005; Broadley et al, 2010; Yao et al, 2010; Zembala et al, 2010; Hasanuzzaman and Fujita, 2011; Hasanuzzaman et al, 2011; Pukacka et al, 2011; Kumar et al, 2012; Pezzarossa et al, 2012; Feng et al, 2013; Ardebili et al, 2014; Ahmad et al, 2016; Kaur et al, 2016; Wu et al, 2016). …”

The present study investigated the beneficial role of selenium (Se) in protecting oilseed rape (Brassica napus L.) plants from cadmium (Cd+2) and lead (Pb+2) toxicity. Exogenous Se markedly reduced Cd and Pb concentration in both roots and shoots. Supplementation of the medium with Se (5, 10, and 15 mg kg-1) alleviated the negative effect of Cd and Pb on growth and led to a decrease in oxidative damages caused by Cd and Pb. Furthermore, Se-enhanced superoxide free radicals (O2true•¯), hydrogen peroxide (H2O2), and lipid peroxidation, as indicated by malondialdehyde accumulation, but decreased superoxide dismutase and glutathione peroxidase activities. Meanwhile, the presence of Cd and Pb in the medium affected Se speciation in shoots. The results suggest that Se could alleviate Cd and Pb toxicity by preventing oxidative stress in oilseed rape plant.
