Geminivirus C2 protein represses genes involved in sulphur assimilation and this effect can be counteracted by jasmonate treatment
(Springer, 2012)
Geminiviruses are plant viruses that infect a broad range of crops and cause extensive losses worldwide, having an important economic impact. C2, a multifunctional pathogenicity factor encoded by geminiviruses, has been ...

Inhibition of Arabidopsis O-acetylserine (Thiol)lyase A1 by tyrosine-nitration
(American Society for Biochemistry and Molecular Biology, 2011)
The last step of sulfur assimilation is catalyzed by O-acetylserine(thiol)lyase (OASTL) enzymes. OASTLs are encoded by a multigene family in the model plant Arabidopsis thaliana. Cytosolic OASA1 enzyme is the main source ...

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 ...

Beyond toxicity: A regulatory role for mitochondrial cyanide
(Landes Bioscience, 2014)
In non-cyanogenic plants, cyanide is a co-product of ethylene and camalexin biosynthesis. To maintain cyanide at non-toxic levels, Arabidopsis plants express the mitochondrial β-cyanoalanine synthase CYS-C1. CYS-C1 knockout ...

Transient Transcriptional Regulation of the CYS-C1 Gene and Cyanide Accumulation upon Pathogen Infection in the Plant Immune Response
(American Society of Plant Biologists, 2013)
Cyanide is produced concomitantly with ethylene biosynthesis. Arabidopsis (Arabidopsis thaliana) detoxifies cyanide primarily through the enzyme b-cyanoalanine synthase, mainly by the mitochondrial CYS-C1. CYS-C1 loss of ...

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 ...

Persulfidation protects from oxidative stress under nonphotorespiratory conditions in Arabidopsis
(Wiley-Blackwell, 2023)
Hydrogen sulfide is a signaling molecule in plants that regulates essential biological processes through protein persulfidation. However, little is known about sulfide-mediated regulation in relation to photorespiration. ...
