H2HUBB TAKEAWAY
In the authors' test, boron-inhibited seed germination and seedling growth, and endogenous H₂ production, were obviously blocked by exogenously applying H₂ The re-establishment of ROS balance was confirmed by reduced lipid peroxidation and ROS accumulation. 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.
What the Findings Mean
H2HUBB reviewed how molecular hydrogen was evaluated in this publication and summarizes the source-grounded findings below. In the authors' test, boron-inhibited seed germination and seedling growth, and endogenous H₂ production, were obviously blocked by exogenously applying H₂ The re-establishment of ROS balance was confirmed by reduced lipid peroxidation and ROS accumulation.
What the Researchers Studied
As the antioxidant properties of hydrogen gas (H₂) were recently described in plants, oxidative stress induced by excess boron was investigated along with other biological responses during rice (Oryza sativa) seed germination to study the beneficial role of H₂.
What Effects Did Molecular Hydrogen Have?
Rice seeds were pretreated with exogenous H₂ Using physiological, pharmacological and molecular approaches, the production of endogenous H₂, growth status, reactive oxygen species (ROS) balance and relative gene expression in rice were measured under boron stress to investigate mechanisms of H₂-mediated boron toxicity tolerance. In the authors' test, boron-inhibited seed germination and seedling growth, and endogenous H₂ production, were obviously blocked by exogenously applying H₂ The re-establishment of ROS balance was confirmed by reduced lipid peroxidation and ROS accumulation. The authors concluded that hydrogen provides boron toxicity tolerance mainly by improving root elongation, water status and ROS balance. As the antioxidant properties of hydrogen gas (H₂) were recently described in plants, oxidative stress induced by excess boron was investigated along with other biological responses during rice (Oryza sativa) seed germination to study the beneficial role of H₂ METHODS.
