Role of glutathione reductase and catalase enzyme in antioxidant defense mechanism in controlling fluoride-induced oxidative stress

ABSTRACT

Fluoride stress is one among the majority of significant abiotic stresses. Fluoride affects plants in negative mannerthrough increasing the level of ROS species and reducing the plant growth. In this studio; Vigna radiata L. wasexposed to fluoride stress in a half-diluted Hoagland solution. In this study, a concentration-dependent analysis (0, 2.5,5, 7.5, 10, 12.5, and 15 mM NaF) of antioxidant enzyme activity performed against the most significant inhibitionof growth levels and content of malondialdehyde, the reduce in chlorophyll contented be report in seedlings treat byNaF compared to controls. Antioxidant biochemical expression (catalase, glutathione reductase) showed the highestactivity at 7.5 mM NaF and showed a significant defense against fluoride stress during the harvest. This study wouldhelp to appreciate the responsibility of antioxidants within the survival of plants against fluoride stress
