“…Our results indicated that GSH partly alleviated the deleterious effect of SS on plant growth, suggesting that GSH might be an active compound participating in SS tolerance of sweet pepper plants, as has previously been observed in rice [ 78 ] and tomato [ 25 ]. The positive response of GSH has previously been reported on some plant species under various stresses [ 27 ], such as water stress [ 79 ], high-temperature stress in mung bean [ 28 ], and lead stress in wheat [ 29 ].…”

“…One of the functions of GSH is to play a positive role in reducing oxidative stress [ 23 ]. Under stress conditions, including salt stress, GSH has been reported to have a positive effect on plants [ 24 , 25 ]. GSH is consumed as a substrate in the glyoxalase system to detoxify MG [ 26 ] and it also maintains cellular redox status, stress signal transmission, and gene expression [ 27 ].…”

“…Some studies have depicted an effective role of externally applied GSH in counteracting a variety of stresses, such as heat stress in mung bean [ 28 ], Pb stress in wheat [ 29 ], and salt stress in mung bean [ 30 ], tomato [ 25 , 31 ], and soybean [ 24 ].…”

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.

“…Reduced glutathione (γ-glutamyl-cysteinyl glycine, GSH) participates in functional activities in many plants [65]. GSH has unique redox and nucleophilic properties and is involved in the cellular defense against the toxic actions of xenobiotics, oxiradicals, salinity, acidity, and metal cations [66].…”

Tomato fruit is rich in antioxidant compounds such as lycopene and β-carotene. The beneficial effects of the bioactive compounds of tomato fruit have been documented as anticancer activities. The objective of this research was to determine whether arsenic (As) causes changes in the content of antioxidant compounds in tomato fruits and whether Silicon nanoparticles (SiO2 NPs) positively influence them. The effects on fruit quality and non-enzymatic antioxidant compounds were determined. The results showed that As decreased the oxide-reduction potential (ORP), while lycopene and β-carotene were increased by exposure to As at a low dose (0.2 mg L−1), and proteins and vitamin C decreased due to high doses of As in the interaction with SiO2 NPs. A dose of 250 mg L−1 of SiO2 NPs increased glutathione and hydrogen peroxide (H2O2), and phenols decreased with low doses of As and when they interacted with the NPs. As for the flavonoids, they increased with exposure to As and SiO2 NPs. The total antioxidant capacity, determined by the ABTS (2,2´-azino-bis[3-ethylbenzthiazolin-6-sulfonic acid]) test, showed an increase with the highest dose of As in the interaction with SiO2 NPs. The application of As at low doses induced a greater accumulation of bioactive compounds in tomato fruit; however, these compounds decreased in high doses as well as via interaction with SiO2 NPs, indicating that there was an oxidative burst.

“…This Solanaceous seedling has categorized as an important model plant in investigating the stress tolerance (Zhang et al, 2018). So, several stress studies have been carried on tomato seedlings such as heat stress (Lyu et al, 2018), water stress (Zhang et al 2018), drought (Bian et al, 2019), salinity (Zhou et al 2019), UV-B stress (Liu et al, 2020), chilling (Dong et al, 2020), and waterlogging (Elkelish et al, 2020). Many strategies could be adapted to overcome these stresses depending on the kind of stress, cultivated plants and its growth stage (Zhou et al, 2020).…”

T HE production of protected cultivation of vegetables could be considered as a sustainable solution in arid and semi-arid regions.These regions already suffer from raising temperature andthe global warmingwill aggravate this, whichrepresents a great challenge facing our universe nowadays. Hence, the production of vegetables and tomato under greenhouse system during the high temperatures may be considered a serious problem should be avoided in these arid zonesin summer due to heat stress.The heat stress may cause a lot of troubles for the tomato seedlings in greenhouses in summer starting with the photosynthetic rate, and the metabolism processes in seedlings and in turn the growth and development of these seedlings. Although studies have recognized heat stress on tomato seedlings, research has yet to systematically investigate the effect of heat stress on tomato seedlings in greenhouse in summer under arid and semi-arid regions particularly in developing countries, which their greenhouses have not any climate controllers. Therefore, the management of tomato seedlings may need to address the production problems caused by heat stress in greenhouse conditions particularly in arid and semi-arid zones
