“…In our previous study, it was found that H 2 S alleviates iron deficiency by promoting iron availability and plant hormone levels in Glycine max seedlings (Chen et al, 2020). Additionally, H 2 S can enhance the establishment of the soybean-rhizobia symbiotic nitrogen fixation system (Zou et al, 2020;Zou et al, 2019). In addition, we recently proved that under nitrogen deficiency condition, the interaction of H 2 S and rhizobia increase biomass and yield, improve the nitrogen utilization efficiency, and affect the expression of senescence related genes in soybean plants .…”

Hydrogen sulphide (H2S), as a new gas signal molecule, participates in the regulation of a variety of abiotic stresses in plants. However, it was unclear how H2S and rhizobia can together to affect the adaptation of soybean to water deficiency. Here, the adaptation mechanism of H2S and rhizobia in soybean to water deficiency was studied. Our results showed that H2S and rhizobia jointly enhanced leaf chlorophyll content, the relative water content (RWC) and caused an increase biomass in soybean under water deficiency. Besides, under water deficiency, H2S enhanced biomass by affecting nodule numbers and nitrogenase activity during the growth of soybean. The expression of soybean nodulation marker genes including early nodulin 40 (GmENOD40), ERF required for nodulation (GmERN), and nodulation inception genes were up-regulated by H2S and rhizobia in nodules. Moreover, the combined effect of H2S and rhizobia were proved to affect the enzyme activities and gene expression level of antioxidant, as well as osmotic protective substance under water deficiency. In addition, the metabolomics results provided that the changes of lipids and lipid-like molecules were remarkably promoted by the combined effect of H2S and rhizobia. Thus, H2S and rhizobia synergistically subsided the oxidative damage by increasing the accumulation of metabolites and strengthening the antioxidant capacity under water deficiency.

“…Endogenous H 2 S production in both young soybean nodules (14 days postinoculation [DPI] with the Sinorhizobium fredii Q8 strain) and mature nodules (28 DPI) can be detected by fluorescent probes SF7-A, whereas no significant fluorescence was observed in the nascent soybean nodules (7 DPI). This suggested that H 2 S may mediate the growth of root nodules [31]. Indeed, the application of NaHS significantly increased the number of soybean nodules and enhanced nitrogenase (Nase) activity after 7 DPI and 24 DPI, respectively.…”

As a recognized signal molecule that interacts with plant hormones to regulate plant growth and development, H 2 S is known to influence the growth of root nodules [30,31].

Hydrogen sulfide (H2S) is regarded as a “New Warrior” for managing plant stress. It also plays an important role in plant growth and development. The regulation of root system architecture (RSA) by H2S has been widely recognized. Plants are dependent on the RSA to meet their water and nutritional requirements. They are also partially dependent on the RSA for adapting to environment change. Therefore, a good understanding of how H2S affects the RSA could lead to improvements in both crop function and resistance to environmental change. In this review, we summarized the regulating effects of H2S on the RSA in terms of primary root growth, lateral and adventitious root formation, root hair development, and the formation of nodules. We also discussed the genes involved in the regulation of the RSA by H2S, and the relationships with other signal pathways. In addition, we discussed how H2S regulates root growth in response to abiotic stress. This review could provide a comprehensive understanding of the role of H2S in roots during development and under abiotic stress.

“…H 2 S is exclusively or partly involved in many major biochemical processes of plants, such as seed germination [26], root organogenesis [27], photosynthesis [28], stomatal aperture [29], plant senescence [30] and post-harvest storage processes [31,32]. H 2 S is also associated with antioxidant mechanisms [33,34], autophagy [35], and various anti-stress processes [36,37]. Although a large number of studies have confirmed that H 2 S is closely related to plant life, the potential mechanism of H 2 S as a signal molecule in plants is being explored.…”

As an endogenous gaseous transmitter, the function of hydrogen sulfide (H2S) has been extensively studied in plants. Once synthesized, H2S may be involved in almost all life processes of plants. Among them, a key route for H2S bioactivity occurs via protein persulfidation, in which process oxidizes cysteine thiol (R-SH) groups into persulfide (R-SSH) groups. This process is thought to underpin a myriad of cellular processes in plants linked to growth, development, stress responses, and phytohormone signaling. Multiple lines of emerging evidence suggest that this redox-based reversible post-translational modification can not only serve as a protective mechanism for H2S in oxidative stress, but also control a variety of biochemical processes through the allosteric effect of proteins. Here, we collate emerging evidence showing that H2S-mediated persulfidation modification involves some important biochemical processes such as growth and development, oxidative stress, phytohormone and autophagy. Additionally, the interaction between persulfidation and S-nitrosylation is also discussed. In this work, we provide beneficial clues for further exploration of the molecular mechanism and function of protein persulfidation in plants in the future.
