Preface
It is known that reactive oxygen species (ROS) are the by-products of aerobic breakdown and are inescapably formed by a number of metabolic pathways and electron transport chains. ROS are partially condensed form of molecular oxygen and normally result from the transfer of electrons to O2 to form, in a succession of univalent reductions, superoxide radical (O2−), hydrogen peroxide (H2O2), and hydroxyl radical (•OH), respectively, or through an electron-independent energy transfer till an excited form of oxygen (singlet oxygen) (Gupta et al. 2016; Halliwell and Gutteridge 2015). Redox signal transduction is a complete feature of aerobic life enriched through evolution to balance evidence from metabolism and the environment. Like all other aerobic creatures, plants maintain most cytosolic thiols in the reduced (−SH) state because of the low thioldisulfide redox potential imposed by millimolar amount of the thiol buffer including glutathione. Plants have developed cellular tactics where the endogenous content of antioxidant enzymes deliver t
