“…The compartmentalization of Na + by OsNHX1 in the vacuoles of the leaf tissues of Pokkali rice leads to pigment stabilization, chlorophyll fluorescence retention, and photosynthetic rate stabilization, resulting in growth maintenance (Theerawitaya et al 2020). A similar result with corn plants was obtained by P improving the photosynthetic apparatus (Fv/Fm, Chl a, Chl b), which resulted in the maintenance of growth under 100 mM NaCl (Kaya and Ashraf 2020).…”

The use of brackish waters is an alternative for the cultivation of fruit-bearing plants in semi-arid regions; nonetheless, sweetsop trees (Annona squamosa L.) are sensitive to these types of waters. However, phosphate fertilization can be a technique used to mitigate the harmful effects of salinity. Thus, our objective was to evaluate the application of phosphorus to mitigate the salinity in irrigation water. The experiment was conducted in a randomized block design, with six treatments S1 (2.5 dS m −1 ) S2 = (4 dS m −1 ), SP1 (2.5 dS m −1 + 1.35 g dm −3 of P 2 O 5 ), SP2 = (4 dS m −1 + 1.35 g dm −3 of P 2 O 5 ), T (control), and P (1.35 g dm −3 of P 2 O 5 ). After 78 days of transplantation, the seedlings were evaluated for the total dry weight (TDW), leaf area (LA), salt tolerance index (STI), water use efficiency (WUE), Na + and K + levels in the shoot and root, chlorophylls a and b, maximum (Fm) and variable (Fv) chlorophyll fluorescence, quantum efficiency of photosystem II (Fv/Fm), total soluble sugar (TSS), total free amino acids (TFAA), proline, and glycine betaine (GB). It was observed that plants treated with SP1 and SP2 show higher results of TDW, LA, STI, WUE, and K in the shoot, Chl a, Chl b, Fm, Fv, Fv/Fm, TFAA, proline, GB, and TSS in relation to S1 and S2. The presence of phosphorus under salinity conditions increased the K + concentration in the shoot, which was responsible for the improvement of pigments as well as increasing the quantum efficiency of photosystem II and carbohydrates, maintaining the growth and, consequently, the salinity tolerance of the sweetsop seedlings.

“…The most special one is DCD2, which can degrade the two isomers of cysteine (Riemenschneider et al 2005 ). The production of endogenous H 2 S via CDes has been confirmed in various physiological and developmental processes of plants (Kaya and Ashraf 2020 ; Shen et al 2013 ), especially DES1 and LCD, which use l -cysteine as the substrate, are the most widespread in plants. The important functions of these two genes will be discussed in detail later.…”

“…Besides, the increases in malondialdehyde (MDA), electrolyte leakage (EL) and proline (Pro) caused by abiotic stress are also important indicators to reflect the oxidative damage of plants. Exogenous spraying or fumigating with H 2 S on plant seedlings could also significantly inhibit the increase in the activity of MDA, EL and Pro (Da-Silva and Modolo 2018 ; Kaya and Ashraf 2020 ; Shan et al 2018 ).…”

“…The activation of H 2 S-related enzymes is also a main way for exogenous H 2 S to alleviate the effect of different stresses. Exogenous application of NaHS can not only increase the activities of d / l -CDes, OAS-TL, CAS and CA enzymes, but also elevate the content of endogenous cysteine and H 2 S (Khan et al 2018 ; Li et al 2019 ), which further amplify the physiological effect of H 2 S. For instance, d / l -CDes, OAS-TL and CAS can be induced by H 2 S under salt-alkali stress (Jiang et al 2019 ; Kaya and Ashraf 2020 ; Li et al 2020c ). Low temperature stimulation can activate d / l -CDes and increase the content of endogenous H 2 S (Aghdam et al 2018 ; Fu et al 2013 ).…”

Hydrogen sulfide (H2S) signaling in plant development and stress responses

Hydrogen sulfide (H 2 S) was initially recognized as a toxic gas and its biological functions in mammalian cells have been gradually discovered during the past decades. In the latest decade, numerous studies have revealed that H 2 S has versatile functions in plants as well. In this review, we summarize H 2 S-mediated sulfur metabolic pathways, as well as the progress in the recognition of its biological functions in plant growth and development, particularly its physiological functions in biotic and abiotic stress responses. Besides direct chemical reactions, nitric oxide (NO) and hydrogen peroxide (H 2 O 2 ) have complex relationships with H 2 S in plant signaling, both of which mediate protein post-translational modification (PTM) to attack the cysteine residues. We also discuss recent progress in the research on the three types of PTMs and their biological functions in plants. Finally, we propose the relevant issues that need to be addressed in the future research.

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.
