“…This contradiction has raised some discussions (Desikan 2010 ). However, subsequent studies seemed to support the conclusion that stomatal closure is promoted by H 2 S (Liu et al 2011 ; Pandey 2014 ; Scuffi et al 2016 ). Drought-induced hormone (i.e., ABA, salicylic acid (SA), jasmonic acid (JA) and ethylene) and ROS signals vary among plants, which promote the accumulation of H 2 S in guard cells and initiate the signals downstream of H 2 S to induce stomatal closure (Deng et al 2020 ; García-Mata and Lamattina 2013 ; Jin et al 2013 ; Liu et al 2011 ; Scuffi et al 2014 ).…”

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.

“…Similar to its roles in metazoans, the overall action of H 2 S is to relieve stress, (Qiao et al 2015), including drought (Jin et al 2011;Christou et al 2013Christou et al , 2014Shen et al 2013); however the underlying mechanisms remain unknown (Pandey 2014). Limited evidence has demonstrated that H 2 S and NO have some overlapping physiological functions in plants ( García-Mata and Lamattina 2013).…”

Emerging evidence suggests that the gaseous molecules hydrogen sulfide (H2S) and nitric oxide (NO) enhances plant acclimation to stress; however, the underlying mechanism remains unclear. In this work, we explored if pretreatment of citrus roots with NaHS (a H2S donor) or sodium nitroprusside (SNP, a NO donor) for 2 days (d) could elicit long-lasting priming effects to subsequent exposure to PEG-associated drought stress for 21 d following a 5 d acclimation period. Detailed physiological study documented that both pretreatments primed plants against drought stress. Analysis of the level of nitrite, NOx, S-nitrosoglutahione reductase, Tyr-nitration and S-nitrosylation along with the expression of genes involved in NO-generation suggested that the nitrosative status of leaves and roots was altered by NaHS and SNP. Using a proteomic approach we characterized S-nitrosylated proteins in citrus leaves exposed to chemical treatments, including well known and novel S-nitrosylated targets. Mass spectrometry analysis also enabled the identification of 42 differentially expressed proteins in PEG alone-treated plants. Several PEG-responsive proteins were down-regulated, especially photosynthetic proteins. Finally, the identification of specific proteins that were regulated by NaHS and SNP under PEG conditions provides novel insight into long-term drought priming in plants and in a fruit crop such as citrus in particular.

“…The enzyme DES1 is required in ABA‐dependent stomatal closure as well as in ABA‐mediated signal transduction pathways (Scuffi et al, 2014; Zhang et al, 2019). Pandey (2014) observed that in des1 knockout mutants, the stomata fail to close even in response to ABA unless an exogenous H 2 S donor is provided.…”

Hydrogen sulfide (H 2 S) is a small, reactive signaling molecule that is produced within chloroplasts of plant cells as an intermediate in the assimilatory sulfate reduction pathway by the enzyme sulfite reductase. In addition, H 2 S is also produced in cytosol and mitochondria by desulfhydration of L-cysteine catalyzed by L-cysteine desulfhydrase (DES1) in the cytosol and from β-cyanoalanine in mitochondria, in a reaction catalyzed by β-cyano-Ala synthase C1 (CAS-C1). H 2 S exerts its numerous biological functions by post-translational modification involving oxidation of cysteine residues (RSH) to persulfides (RSSH). At lower concentrations (10-1000 μmol L À1 ), H 2 S shows huge agricultural potential as it increases the germination rate, the size, fresh weight, and ultimately the crop yield. It is also involved in abiotic stress response against drought, salinity, high temperature, and heavy metals. H 2 S donor, for example, sodium hydrosulfide (NaHS), has been exogenously applied on plants by various researchers to provide drought stress tolerance. Exogenous application results in the accumulation of polyamines, sugars, glycine betaine, and enhancement of the antioxidant enzyme activities in response to drought-induced osmotic and oxidative stress, thus, providing stress adaptation to plants. At the biochemical level, administration of H 2 S donors reduces malondialdehyde content and lipoxygenase activity to maintain the cell integrity, causes abscisic acid-mediated stomatal closure to prevent water loss through transpiration, and accelerates the photosystem II repair cycle. Here, we review the crosstalk of H 2 S with secondary messengers and phytohormones towards the regulation of drought stress response and emphasize various approaches that can be addressed to strengthen research in this area. | INTRODUCTIONDrought-induced osmotic stress restricts the overall growth of plants due to the low rate of water absorption by roots and the high rate of transpiration (Blum, 1996). In addition to this, water deficiency leads to a significant reduction in leaf cell turgor, which ultimately causes a restriction in the expansion of cells, decreases leaf area, and rate of photosynthesis, thereby inhibiting the buildup of biomass (Chaves et al., 2003;Raja et al., 2020). Drought causes an imbalance between light capture and its utilization which results in the accumulation of reactive oxygen species (ROS) in the chloroplast, leading to disorganization of thylakoid membranes (Hussain et al., 2018;Kosar et al., 2020;Ladjal et al., 2000) and inactivation of photosystem II (PS II) by inhibition, both in the flow of electrons and electron transfer from the reduced plastoquinone (PQ) pool to the PS I reaction center (Dąbrowski et al., 2019;Giardi et al., 1996), as a consequence of oxidative stress. Net photosynthetic rate, chlorophyll fluorescence, and antioxidant activities in soybean were also influenced by water deficit (Iqbal et al., 2019). Several measures have evolved in plants to sustain photosynthetic activity by repairin...
