Abstract
Boron (B) toxicity is an abiotic stressor in plants due to the narrow threshold range between B deficiency and B toxicity.Glutathione (GSH) has been reported to reduce abiotic stress in plants, but its effect on B toxicity alleviation, particularly in riceseedlings, is not clear. Therefore, the present research yields information on the antioxidant mechanism, nitrogen metabolism, cell wallcomponents, and B concentrations that allow rice seedlings to withstand the adverse effects of B toxicity by GSH application. The resultssuggest that B toxicity suppressed the growth traits of rice. However, GSH treatment exhibited a positive influence on the growth ofrice seedlings. GSH application reduced B uptake and translocation in shoots (28.44%) while accumulating higher B concentrations inroots (39.69%). The cell wall components were increased by GSH treatment, creating more negatively charged ions on the cell wall for Badsorption. GSH application resulted in reduced accumulation of ammonium and increased total nitrogen contents in leaves. Moreover,N metabolism enzymes were increased by GSH application. The overall outcomes show the function of glutathione in reducing theadverse effects of B toxicity on rice plants. This study provides insight into the function of glutathione in rice, which could be an efficientway to boost plant resistance to abiotic stress factors like B toxicity.
