H2HUBB TAKEAWAY
In a laboratory model, endogenous H₂ production exhibited lower level in aleurone layers under GA treatment, whereas the H₂ production was apparently increased under abscisic acid (ABA) treatment. The authors concluded that the study therefore suggests that HRW-triggered alleviation of wheat aleurone layer PCD induced by GA results from a combination of H₂-mediated decreases of ROS levels, including O₂.-, H₂O₂, and ·OH. These findings come from a laboratory model and suggest molecular hydrogen's biological potential. Further research is needed to determine clinical relevance.
What the Researchers Tested
Laboratory experiment
How Molecular Hydrogen Was Used
Hydrogen gas (H₂) has been recently regarded as a novel gaseous signaling molecule that performs multiple functional roles in plant. Here, the researchers demonstrate that hydrogen rich water (HRW)-an experimentally tractable reagent to assess the effects of the H₂ significantly delays wheat aleurone layer programmed cell death (PCD) induced by gibberellic acid (GA). Endogenous H₂ production exhibited lower level in aleurone layers under GA treatment, whereas the H₂ production was apparently increased under abscisic acid (ABA) treatment.
