Effect of High-Temperature Stress on Ascorbate–Glutathione Cycle in Maize

High-temperature stress induces cellular changes leading to over-production of highly reactive oxygen species (ROS) which damage macromolecules and cell organelles, eventually resulting in cell death. Antioxidative metabolism in plants comprising of enzymatic and non-enzymatic antioxidants imparts tolerance by scavenging or detoxification of excess ROS. We investigated the response of major H2O2-detoxifying system, the AsA–GSH cycle in four...
