H2 Enhances Arabidopsis Salt Tolerance by Manipulating ZAT10/12-Mediated Antioxidant Defence and Controlling Sodium Exclusion

Background The metabolism of hydrogen gas (H2) in bacteria and algae has been extensively studied for the interesting of developing H2-based fuel. Recently, H2 is recognized as a therapeutic antioxidant and activates several signalling pathways in clinical trials. However, underlying physiological roles and mechanisms of H2 in plants as well as its signalling cascade remain unknown.
