“…A recent publication demonstrated that treatment with JA promoted endogenous H 2 S generation and that treatments with exogenous H 2 S donors significantly enhanced JA-induced cadmium tolerance [ 167 ]. This observation was also described by other authors, whose research described that JA treatments increased D-cysteine desulfhydrase activity and that this JA-induced H 2 S regulated ascorbate and glutathione metabolism [ 61 ]. Taken together, these data suggest intertwined signaling between H 2 S and this plant hormone.…”

“…The first mechanism proposed for H 2 S was based on its chemical properties, since this nucleophilic molecule is able to react with reactive oxygen/nitrogen species and reduce the cellular oxidative state [58,59]. In addition, H 2 S is able to regulate several antioxidant enzymes, such as ascorbate peroxidase (APX) [60][61][62], catalase (CAT) [63,64], superoxide dismutase (SOD) [63,65], and glutathione reductase (GR) [62], and non-enzymatic compounds, such as the glutathione anti-oxidant pool [66,67].…”

Hydrogen sulfide (H2S) has always been considered toxic, but a huge number of articles published more recently showed the beneficial biochemical properties of its endogenous production throughout all regna. In this review, the participation of H2S in many physiological and pathological processes in animals is described, and its importance as a signaling molecule in plant systems is underlined from an evolutionary point of view. H2S quantification methods are summarized and persulfidation is described as the underlying mechanism of action in plants, animals and bacteria. This review aims to highlight the importance of its crosstalk with other signaling molecules and its fine regulation for the proper function of the cell and its survival.

“…15 Our previous study showed that H 2 S regulates AsA/DHA ratio in JA signaling through APX, GR, DHAR, MDHAR and GalLDH in Arabidopsis leaves. 16 We and other researchers reported that MEK1/2 also regulates AsA/DHA ratio in JA signaling through APX, GR, DHAR, MDHAR, and GalLDH. 9,10 However, the relationship between H 2 S and MEK1/2 in JA signaling in regulating AsA/DHA ratio remains unknown.…”

“…It has been documented that H 2 S synthetase D-cysteine desulfhydrase (D-CDes) is also one important enzyme responsible for the production of H 2 S in plants. 16 Thus, further studies should been taken to investigate the effects of JA on the activity and transcript level of D-CDes, which will give us more information for JAregulated the production of H 2 S in A. thaliana.…”

In this paper, we investigated the relationship between hydrogen sulfide (H 2 S) and mitogen-activated protein kinase kinase (MEK1/2) in jasmonic acid (JA)-regulated the redox state of ascorbate in the leaves of Arabidopsis thaliana. The results showed that JA significantly enhanced the phosphorylation level of MEK1/2, the production of endogenous H 2 S and the ratio of reduced ascorbate (AsA) to dehydroascorbate (DHA) (AsA/DHA) in wild type of A. thaliana (WT). However, there were no obvious effects of JA on above indicators in H 2 S synthetic mutant of A. thaliana (MT). H 2 S scavenger hypotaurine (HT) markedly reduced JA-induced the phosphorylation level of MEK1/2, AsA/DHA ratio and the production of endogenous H 2 S in WT. Application of H 2 S donor sodium hydrosulfide (NaHS) to JA-treated MT plants increased above indicators. Application of NaHS to (HT+JA)treated MT plants did not reverse the effects of HT on above JA-induced indicators. MEK1/2 inhibitor PD98059 decreased JA-induced AsA/DHA ratio and the transcript levels and the activities of ascorbate peroxidase (APX), glutathione reductase (GR), monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR) and L-galactono-1,4-lactone dehydrogenase (GalLDH) in WT. However, PD98059 had no effect on JA-induced the production of endogenous H 2 S in WT. Compared with Control-MT, there were no obvious effects of JA on the production of endogenous H 2 S, AsA/DHA ratio and the transcript levels and activities of above enzymes in MT. However, application of PD98059 reduced above JA-induced indicators except the production of endogenous H 2 S and DHA content in MT. Our results suggested that H 2 S activated MEK1/2 in JA-regulated AsA/DHA ratio in A. thaliana leaves through enzymes in ascorbate metabolism.

As one of the most destructive pests, aphids cause significant damage on various agricultural and horticultural crops. Recently, melatonin has been shown to enhance plant resistance to aphids; however, the underlying mechanisms remain unclear. In this study, our results showed that melatonin, MeJA, and H2S enhanced aphid resistance of watermelon in a dose‐dependent manner, accompanied by increases in the defense‐related enzyme activities and lignin accumulation. On the plants pretreated with 100 μM melatonin, 100 μM MeJA, and 50 μM NaHS, the numbers of aphids were 86.0%, 59.6%, and 47.9% lower than that on control plants, respectively, after aphid infestation for 7 days. Melatonin application induced MeJA and H2S accumulation in response to aphid infestation, while inhibition of MeJA and H2S accumulation attenuated or abolished melatonin‐induced defense response and aphid resistance, suggestive of the involvement of MeJA and H2S in melatonin‐induced aphid resistance. MeJA also increased H2S accumulation, but inhibition of MeJA biosynthesis prevented melatonin‐enhanced H2S accumulation, suggesting that MeJA mediates melatonin‐induced H2S accumulation. Furthermore, inhibition of H2S production attenuated MeJA‐induced defense response and aphid resistance. Taken together, the current study reveals a novel mechanism in which MeJA‐dependent H2S signaling is involved in melatonin‐induced defense response and subsequent aphid resistance. The increasing concern to minimize the use of pesticides and to switch onto sustainable and natural control strategies indicates the great exploitation of such a mechanism in combating aphids.
