Beta-Cyanoalanine synthase action in root hair elongation is exerted at early steps of the root hair elongation pathway and is independent of direct cyanide inactivation of NADPH oxidase
(Oxford University Press, 2018)
In Arabidopsis thaliana, cyanide is produced concomitantly with ethylene biosynthesis and is mainly detoxified by the ß-cyanoalanine synthase CAS-C1. In roots, CAS-C1 activity is essential to maintain a low level of cyanide ...

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 ...

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 ...

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. ...

You have access HCN regulates cellular processes through posttranslational modification of proteins by S-cyanylation
(American Society of Plant Biologists, 2019)
Hydrogen cyanide (HCN) is coproduced with ethylene in plant cells and is primarily enzymatically detoxified by the mitochondrial β-CYANOALANINE SYNTHASE (CAS-C1). Permanent or transient depletion of CAS-C1 activity in ...

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-generated sulfide in the cytosol negatively regulates autophagy and modulates the transcriptional profile in arabidopsis
(American Society of Plant Biologists, 2012)
In Arabidopsis thaliana, DES1 is the only identified l-Cysteine desulfhydrase located in the cytosol, and it is involved in the degradation of cysteine and the concomitant production of H2S in this cell compartment. Detailed ...

Hydrogen sulfide action in the regulation of plant autophagy
(Wiley-Blackwell, 2022)
Hydrogen sulfide is a signalling molecule with a well-established impact on both plant and animal physiology. Intense investigation into the regulation of autophagy by sulfide in Arabidopsis thaliana has revealed that the ...

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 ...

Hydrogen Sulfide: A Key Role in Autophagy Regulation from Plants to Mammalians
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Autophagy is a degradative conserved process in eukaryotes to recycle unwanted cellular protein aggregates and damaged organelles. Autophagy plays an important role under normal physiological conditions in multiple biological ...
