Hydrogen sulfide (H2S) is a signaling molecule that regulates critical processes and allows plants to adapt to adverse conditions. The molecular mechanism underlying the H2S action relies on its chemical reactivity, and the mainly characterized is the persulfidation, which involves the modification of protein thiol groups, resulting in the formation of persulfide groups. This modification derives a change of protein function, altering catalytic activity or intracellular location and inducing important physiological effects. H2S cannot react directly with thiols but instead can react with oxidized cysteine residues; therefore, H2O2 signaling through sulfenylation is required for persulfidation. A comparative study performed in this review reveals 82% of identity between the sulfenylome and persulfidome. With regard to abscisic acid (ABA) signaling, widespread evidence shows an interconnection between H2S and ABA in the plant response to environmental stress. Proteomic analyses have revealed persulfidation of several proteins involved in the ABA signaling network and have shown that persulfidation is triggered in response to ABA. In guard cells, a complex interaction of H2S and ABA signaling has also been described, and the persulfidation of specific signaling components seems to be the underlying mechanism.

“…However, at lower concentrations (10-1000 μmol L À1 ) it is involved in signaling in combination with other small reactive molecules such as H 2 O 2 , NO, and carbon monoxide (CO) (Caverzan et al, 2021;Hancock 2019;Lisjak et al, 2013;Olson, 2009). The signaling property of H 2 S may be attributed to its ability to interact with thiol (ÀSH) groups of cysteine residues of proteins via post-translational modification (PTM) such as persulfidation (Aroca et al, 2018;Corpas et al, 2019;Liu Q, Zhou, et al, 2021). Protein persulfidation involves a redox modification that controls various physiological processes in plants (Aroca et al, 2020;Filipovic & Jovanovic, 2017;Gotor et al, 2019).…”

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...

“…PLDα1 and H2S alleviate osmotic stress by suppressing ROS and maintaining membrane integrity [ 153 ]. When PLDδ was associated with a wider stomatal aperture under osmotic stress, a lower H2S content or expressed L-cysteine desulfhydrase was shown (LCD; [ 154 ]). In both cases, PLD action enhances the alleviation of osmotic stress by triggering stomatal closure, which could reduce transpiration, prevent water loss, and maintain cell turgor pressure under drought stress [ 153 , 154 ].…”

Plants, as sessile organisms, have adapted a fine sensing system to monitor environmental changes, therefore allowing the regulation of their responses. As the interaction between plants and environmental changes begins at the surface, these changes are detected by components in the plasma membrane, where a molecule receptor generates a lipid signaling cascade via enzymes, such as phospholipases (PLs). Phospholipids are the key structural components of plasma membranes and signaling cascades. They exist in a wide range of species and in different proportions, with conversion processes that involve hydrophilic enzymes, such as phospholipase-C (PLC), phospholipase-D (PLD), and phospholipase-A (PLA). Hence, it is suggested that PLC and PLD are highly conserved, compared to their homologous genes, and have formed clusters during their adaptive history. Additionally, they generate responses to different functions in accordance with their protein structure, which should be reflected in specific signal transduction responses to environmental stress conditions, including innate immune responses. This review summarizes the phospholipid systems associated with signaling pathways and the innate immune response.
