H2S‐Mediated GH3.1 Persulfidation Regulates IAA Homeostasis to Enhance Nodulation Formation and Nitrogen Fixation in Robinia pseudoacacia

Molecular Plant Pathology, Volume 26, Issue 10, October 2025.
H2S persulfidates GH3.1 at Cys304, reducing its activity, sustaining IAA levels, triggering H2S‐IAA feedback, enhancing nodulation gene expression, boosting nodule formation, nitrogen fixation and Robinia pseudoacacia growth. ABSTRACT Hydrogen sulphide (H2S), a gaseous signalling molecule, plays a multifaceted role in plant physiology by enhancing ...

Plant catalases as NO and H2S targets

Redox Biology, 2020
Catalase is a powerful antioxidant metalloenzyme located in peroxisomes which also plays a central role in signaling processes under physiological and adverse situations. Whereas animals contain a single catalase gene, in plants this enzyme is encoded by

Hydrogen sulfide promotes lateral root formation in peach through persulfidation of SnRK1α kinase

Plant Biotechnology Journal, Volume 23, Issue 10, Page 4395-4411, October 2025.
Summary Root development is crucial for the growth and yield of horticultural crops. Hydrogen sulfide (H2S), an important gasotransmitter, has been shown to regulate lateral root (LR) formation in plants, including peach (Prunus persica). However, its specific regulatory mechanism remains largely unclear.

Cysteine Signalling in Plant Pathogen Response

Plant, Cell &Environment, Volume 48, Issue 10, Page 7107-7122, October 2025.
ABSTRACT The amino acid cysteine is the precursor for a wide range of sulfur‐containing functional molecules in plants, including enzyme cofactors and defence compounds. Due to its redox active thiol group cysteine is highly reactive. Synthesis and degradation pathways are present in several subcellular compartments to adjust the intracellular cysteine

Protein Persulfidation Protects Against Aging

, 2019
For couple of decades aging is believed to be a consequence of damages accumulated by increased production of reactive oxygen species (ROS). Opposite to that, dietary restriction attempts to extend life have been linked to increased H2S production.

Mitochondria‐Nuclear Crosstalk: Orchestrating mtDNA Maintenance

Environmental and Molecular Mutagenesis, Volume 66, Issue 5, Page 222-242, June 2025.
ABSTRACT The mitochondria (mt) and nucleus engage in a dynamic bidirectional communication to maintain cellular homeostasis, regulating energy production, stress response, and cell fate. Anterograde signaling directs mt function, while retrograde signaling conveys metabolic and stress‐related changes from mt to the nucleus. Central to this crosstalk is

Supersulfides: A Promising Therapeutic Approach for Autoinflammatory Diseases

Microbiology and Immunology, Volume 69, Issue 4, Page 191-202, April 2025.
ABSTRACT Supersulfides are molecular species characterized by catenated sulfur moieties, including low‐molecular‐weight and protein‐bound supersulfides. Emerging evidence suggests that these molecules, abundantly present in diverse organisms, play essential roles far beyond their chemical properties, such as functions in energy metabolism, protein ...

Anomalous Kv7 channel activity in human malignant hyperthermia syndrome unmasks a key role for H2S and persulfidation in skeletal muscle [PDF]

, 2020
Background and Purpose: Human malignant hyperthermia (MH) syndrome is induced by volatile anaesthetics and involves increased levels of cystathionine β-synthase (CBS)-derived H2S within skeletal muscle.

Anti-aging properties of protein persulfidation

, 2018
An oxidative-posttranslational modification of thiols called protein persulfidation (RSSH) represents the underlying mechanism of biological actions ascribed to new gasotransmitter hydrogen sulfide (H2S).
