Signaling in the plant cytosol: cysteine or sulfide?
(Springer, 2015)
Cysteine (Cys) is the first organic compound containing reduced sulfur that is synthesized in the last stage of plant photosynthetic assimilation of sulfate. It is a very important metabolite not only because it is crucial ...

Signaling by hydrogen sulfide and cyanide through post-translational modification
(Oxford University Press, 2019)
Two cysteine metabolism-related molecules, hydrogen sulfide and hydrogen cyanide, which are considered toxic, have now been considered as signaling molecules. Hydrogen sulfide is produced in chloroplasts through the activity ...

Persulfidation is the mechanism underlying sulfide-signaling of autophagy
(Taylor & Francis, 2021)
In this commentary, we highlight the findings described in a recent paper regarding the mechanism of H2S regulation of macroautophagy/autophagy in mammalian cells and discuss the similarities/divergencies with plant cells. ...

Abscisic acid-triggered persulfidation of the cys protease ATG4 mediates regulation of autophagy by sulfide
(American Society of Plant Biologists, 2020)
Hydrogen sulfide is a signaling molecule that regulates essential processes in plants, such as autophagy. In Arabidopsis (Arabidopsis thaliana), hydrogen sulfide negatively regulates autophagy independently of reactive ...

Persulfidation proteome reveals the regulation of protein function by hydrogen sulfide in diverse biological processes in Arabidopsis
(Oxford University Press, 2017)
Hydrogen sulfide-mediated signaling pathways regulate many physiological and pathophysiological processes in mammalian and plant systems. The molecular mechanism by which hydrogen sulfide exerts its action involves ...

Cysteine and cysteine-related signaling pathways in arabidopsis thaliana
(Oxford University Press, 2014)
Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor molecule involved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its derivative ...

S-Sulfhydration: A Cysteine Posttranslational Modification in Plant Systems
(American Society of Plant Biologists, 2015)
Hydrogen sulfide is a highly reactive molecule that is currently accepted as a signaling compound. This molecule is as important as carbon monoxide in mammals and hydrogen peroxide in plants, as well as nitric oxide in ...

Sulfide promotes tolerance to drought through protein persulfidation in Arabidopsis
(Oxford University Press, 2023-08-17)
Hydrogen sulfide (H2S) is a signaling molecule that regulates essential plant processes. In this study, the role of H2S during drought was analysed, focusing on the underlying mechanism. Pretreatments with H2S before ...

Hydrogen sulfide signaling in plant adaptations to adverse conditions: molecular mechanisms
(Oxford University Press, 2021)
Hydrogen sulfide (H2S) is a signaling molecule that regulates critical processes and allows plants to adapt to adverse conditions. The molecular mechanism underlying H2S action relies on its chemical reactivity, and the ...

Hydrogen sulfide regulates the cytosolic/nuclear partitioning of glyceraldehyde-3-phosphate dehydrogenase by enhancing its nuclear localization
(Oxford University Press, 2017)
Hydrogen sulfide is an important signaling molecule comparable with nitric oxide and hydrogen peroxide in plants. The underlying mechanism of its action is unknown, although it has been proposed to be S-sulfhydration. This ...
