Three strategies are involved in Si enhancement of plant tolerance to high temperatures (43 ± 0.5 °C). In strategy I, Si enhances the antioxidant enzyme activity by both upregulating the expression of antioxidant enzyme genes and reducing the decrease of MDA and O2 caused by Reactive Oxygen Species (ROS). In strategy II, Si activates the heat shock proteins and drought tolerance genes such as SlDREB2 and SlMAPK1. In strategy III, Si downregulates stress-related hormones, such as ABA and SA
