Fig. 7From: Melatonin alleviates heat-induced damage of tomato seedlings by balancing redox homeostasis and modulating polyamine and nitric oxide biosynthesisEffects of Melatonin (100 μM) on relative transcript expression of (A) Respiratory burst oxidase (RBOH) and (B) heat shock factor A 2 (HsfA2) (C) heat shock protein 90 (HSP90) 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
