Hydrogen Sulfide: A Signal Molecule in Plant Cross-Adaptation

  title={Hydrogen Sulfide: A Signal Molecule in Plant Cross-Adaptation},
  author={Zhong-Guang Li and Xiong Min and Zhi-Hao Zhou},
  journal={Frontiers in Plant Science},
For a long time, hydrogen sulfide (H2S) has been considered as merely a toxic by product of cell metabolism, but nowadays is emerging as a novel gaseous signal molecule, which participates in seed germination, plant growth and development, as well as the acquisition of stress tolerance including cross-adaptation in plants. Cross-adaptation, widely existing in nature, is the phenomenon in which plants expose to a moderate stress can induce the resistance to other stresses. The mechanism of cross…

Hydrogen Sulfide in Plant Abiotic Stress Tolerance

The growing importance of H2S and insufficient knowledge on its functions and targets in plants calls for further detailed analyses at the physiological, biochemical and molecular levels before fully accepting its signaling roles in plant stress tolerance.

Hydrogen Sulfide: A Robust Combatant against Abiotic Stresses in Plants

Hydrogen sulfide is predominantly considered as a gaseous transmitter or signaling molecule in plants and its role during abiotic stresses, crosstalk of H2S with other biomolecules such as NO and phytohormones have also been explored in plant signaling.

Hydrogen sulfide-An emerging signalling molecule regulating drought stress response in plants.

The crosstalk of H2 S with secondary messengers and phytohormones towards the regulation of drought stress response is reviewed and various approaches that can be addressed are emphasized to strengthen research in this area.

Crosstalk between Hydrogen Sulfide and Other Signal Molecules Regulates Plant Growth and Development

The functions of H2S at different stages of plant development are reviewed, focusing on the S-sulfhydration of proteins mediated by H 2S and the crosstalk between H2 S and other signaling molecules.

Stress Responsive Gene Regulation in Relation to Hydrogen Sulfide in Plants under Abiotic Stress.

The current article is aimed to summarize the recent updates on H2 S-mediated gene regulation in special reference to abiotic stress tolerance mechanism, and cross adaptation in plants.

Revealing on hydrogen sulfide and nitric oxide signals co-ordination for plant growth under stress conditions.

Understanding the change and mechanism of H2 S and NO mediated cell signalling will broaden the knowledge on the various biochemical changes that occur in plant cells related to different stresses to protect plants against abiotic stresses and to improve crop productivity.

The metabolism of signal molecule hydrogen sulfi de and its role in the acquisition of heat tolerance in plants

High temperature is a major factor that limits growth, development and production in plants. Hydrogen sulfide(H_2S) is a third endogenous gaseous signal molecule after carbon monoxide(CO) and nitric

Hydrogen sulfide as a signal molecule in hematin-induced heat tolerance of tobacco cell suspension

It is suggested that CO pretreatment could improve the heat tolerance of tobacco suspension cultured cells, and H2S might exert its signal role downstream to CO-induced heat tolerance.

Analysis of some enzymes activities of hydrogen sulfide metabolism in plants.

Different Modes of Hydrogen Peroxide Action During Seed Germination

How seed priming/conditioning affects the integrative role of hydrogen peroxide in seed germination and aging is outlined and the detrimental effects of H2O2 on seed biology is focused on.

Hydrogen sulfide: environmental factor or signalling molecule?

It appears that instead of thinking of H₂S as a phytotoxin, it needs to be considered as a signalling molecule that interacts with reactive oxygen species and NO metabolism, as well as having direct effects on the activity of proteins.

H2S acting as a downstream signaling molecule of SA regulates Cd tolerance in Arabidopsis

H2S may be a downstream signal molecule in SA-induced Cd tolerance of Arabidopsis, which indicated that the plants exhibited enhanced tolerance to Cd when pretreated with SA, which included weakening oxidative damage and intensifying photosynthesis as well as boosting L-cysteine desulfhydrase activity and raising the content of endogenous H2S.

REVIEW ARTICLE Hydrogen sulphide: a versatile tool for the regulation of growth and defence responses in horticultural crops

The present review proposes a practical role for H2S in horticultural crop physiology, further supporting the notion that H 2S acts as a key signalling molecule in plants, possibly acting by “cross-talk” with other secondary plant cell messengers.

Hydrogen sulfide is involved in the chilling stress response in Vitis vinifera L.

Hydrogen sulfide (H 2 S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the

Hydrogen sulfide is a mediator in H2O2-induced seed germination in Jatropha Curcas

It is suggested that pretreatment of H2O2 could improve germination percentage of J.curcas seeds and this improvement was mediated by H2S.

Synergistic effect of antioxidant system and osmolyte in hydrogen sulfide and salicylic acid crosstalk-induced heat tolerance in maize (Zea mays L.) seedlings

Results showed that antioxidant system and osmolyte play a synergistic role in SA and H2S crosstalk-induced heat tolerance of maize seedlings.
