Research-use notice
Independent study record
Each H2HUBB study page organizes source-linked research details for educational use. Interpretation should remain proportional to the study design, population, controls, and limitations.
H2HUBB TAKEAWAY
Finally, S-nitrosylation of MEK1 increased its interaction with GSNOR, and H₂ further promoted this interaction under salt stress. This source-grounded publication contributes evidence relevant to molecular hydrogen and is retained in a transparent general research category when a more specific study design is not supported by the indexed record.
How Molecular Hydrogen Was Addressed
Hydrogen gas (H₂) effectively alleviates abiotic stress in horticultural plants. S-nitrosoproteomic analysis revealed that MEK1, a conserved MAPK component, was notably induced and S-nitrosylated by NO and H₂ under salt stress.
What the Publication Reported
Finally, S-nitrosylation of MEK1 increased its interaction with GSNOR, and H₂ further promoted this interaction under salt stress.
Authors’ Conclusion
The authors concluded that the findings indicate that H₂ may enhance the salinity tolerance in tomato seedlings by orchestrating the interplay between S-nitrosylated MEK1 and GSNOR.
