Hydrogen sulfide (H2S) and nitric oxide (NO) alleviate cobalt toxicity in wheat (Triticum aestivum L.) by modulating photosynthesis, chloroplastic redox and antioxidant capacity
Abstract
Growth, water content and osmotic potential decreased under Co stress. Stress caused a disruption in the photosynthetic capacity in wheat leaves. Hydrogen peroxide and lipid peroxidation were induced under stress. SNP/NaHS together with cobalt ameliorated the toxic effect on chloroplast of wheat. SNP/NaHS maintain of the redox state of ascorbate-glutathione cycle in chloroplast.
