“…Application of H 2 S donor NaHS or Na 2 S could significantly inhibit the decay and mildew of postharvest fruits, and prolong their storage time (Ali et al 2019 ; Mukherjee 2019 ; Ziogas et al 2018 ). Exogenous H 2 S can regulate the redox balance, hormone level, thiometabolism and energy metabolism in fruits, maintain the homeostasis of various secondary metabolites and the integrity of cell wall and cell membrane, as well as help to resist the invasion of a variety of fungi by inhibiting the mycelial germination (Table S2).…”

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.

“…H 2 S is a well-known important gaseous signaling molecule involved in plant developmental and environmental responses, such as root organogenesis, response to abiotic stresses, and delayed senescence of vegetables, fruits, and flowers ( Zhang et al, 2011 ; Li et al, 2012 , 2013 ; Wang et al, 2012 ; Ali et al, 2019 ; Corpas, 2019 ; Mei et al, 2019 ). It has been confirmed that L-cysteine desulfhydrase-dependent H 2 S acts as the downstream signal molecule involved in NO-induced heat tolerance of maize seedlings ( Li et al, 2013 ) and methane-induced tomato and Arabidopsis lateral root formation ( Mei et al, 2019 ).…”

Magnesium Hydride-Mediated Sustainable Hydrogen Supply Prolongs the Vase Life of Cut Carnation Flowers via Hydrogen Sulfide

Magnesium hydride (MgH2) is a promising solid-state hydrogen source with high storage capacity (7.6 wt%). Although it is recently established that MgH2 has potential applications in medicine because it sustainably supplies hydrogen gas (H2), the biological functions of MgH2 in plants have not been observed yet. Also, the slow reaction kinetics restricts its practical applications. In this report, MgH2 (98% purity; 0.5–25 μm size) was firstly used as a hydrogen generation source for postharvest preservation of flowers. Compared with the direct hydrolysis of MgH2 in water, the efficiency of hydrogen production from MgH2 hydrolysis could be greatly improved when the citrate buffer solution is introduced. These results were further confirmed in the flower vase experiment by showing higher efficiency in increasing the production and the residence time of H2 in solution, compared with hydrogen-rich water. Mimicking the response of hydrogen-rich water and sodium hydrosulfide (a hydrogen sulfide donor), subsequent experiments discovered that MgH2-citrate buffer solution not only stimulated hydrogen sulfide (H2S) synthesis but also significantly prolonged the vase life of cut carnation flowers. Meanwhile, redox homeostasis was reestablished, and the increased transcripts of representative senescence-associated genes, including DcbGal and DcGST1, were partly abolished. By contrast, the discussed responses were obviously blocked by the inhibition of endogenous H2S with hypotaurine, an H2S scavenger. These results clearly revealed that MgH2-supplying H2 could prolong the vase life of cut carnation flowers via H2S signaling, and our results, therefore, open a new window for the possible application of hydrogen-releasing materials in agriculture.

“…Postharvest maturation of fruits and vegetables is also a type of senescence. H 2 S treatment positively regulates certain physiological aspects of ripening, such as color metabolism, softening, and postharvest decay during storage, suggesting that H 2 S might regulate aging to protect the ripening and quality changes in various fruits and vegetables [ 17 ]. In addition, H 2 S can eliminate ROS in harvested produce by promoting the activities of antioxidant enzymes, through synergism (NO) or antagonism (ET) with other molecules, and by regulating the expression of SAGs related to protein and chlorophyll degradation in order to maintain the integrity of membranes and to slow senescence [ 67 ].…”

“…In Arabidopsis, mutation of des1 leads to premature senescence of leaves [ 15 ]. In many fruits and vegetables, H 2 S treatment delays premature leaf senescence and the decay of fruits after harvest via reducing the accumulation of reactive oxygen species (ROS) [ 16 , 17 ] and inhibits the abscission of plant organs via increasing the content of auxin in abscission zone tissues [ 18 ]. A recent report has shown that there is a significant increase in the S-sulfhydration level of the actin proteins in an H 2 S-overproducing line, created by the over-expression of LCD in the Arabidopsis O-acetylserine(thiol)lyase isoform a1 ( oasa1 ) mutant ( OE LCD-5 / oas-a1 ).…”

Hydrogen sulfide (H2S), once recognized only as a poisonous gas, is now considered the third endogenous gaseous transmitter, along with nitric oxide (NO) and carbon monoxide (CO). Multiple lines of emerging evidence suggest that H2S plays positive roles in plant growth and development when at appropriate concentrations, including seed germination, root development, photosynthesis, stomatal movement, and organ abscission under both normal and stress conditions. H2S influences these processes by altering gene expression and enzyme activities, as well as regulating the contents of some secondary metabolites. In its regulatory roles, H2S always interacts with either plant hormones, other gasotransmitters, or ionic signals, such as abscisic acid (ABA), ethylene, auxin, CO, NO, and Ca2+. Remarkably, H2S also contributes to the post-translational modification of proteins to affect protein activities, structures, and sub-cellular localization. Here, we review the functions of H2S at different stages of plant development, focusing on the S-sulfhydration of proteins mediated by H2S and the crosstalk between H2S and other signaling molecules.
