Fig. 6From: Melatonin alleviates heat-induced damage of tomato seedlings by balancing redox homeostasis and modulating polyamine and nitric oxide biosynthesisEffects of Melatonin (100 μM) on antioxidant enzymes activities and their related transcript expression of (A, E) glutathione reductase (GR), (B, F) monodehydroascorbate reductase (MDHAR), (C, G) dehydroascorbate reductase (DHAR) and (D, H) glutathione S-transferase (GST) in leaves of tomato seedlings in presence or absence of high temperature (42 °C) stress. Data represent as a mean of standard deviation (SD) of three replications. Different letters indicate significant differences according to Tukey’s HSD test at P ≤ 0.05Back to article page
