This book provides detailed and comprehensive information on
oxidative damage caused by stresses in plants with especial
reference to the metabolism of reactive oxygen species (ROS). In
plants, as in all aerobic organisms, ROS are common by-products
formed by the inevitable leakage of electrons onto O2 from the
electron transport activities located in chloroplasts,
mitochondria, peroxisomes and in plasma membranes or as a
consequence of various metabolic pathways confined in different
cellular loci. Environmental stresses such as heat, cold, drought,
salinity, heavy-metal toxicity, ozone and ultraviolet radiation as
well as pathogens/contagion attack lead to enhanced generation of
ROS in plants due to disruption of cellular homeostasis. ROS play a
dual role in plants; at low concentrations they act as signaling
molecules that facilitate several responses in plant cells,
including those promoted by biotic and abiotic agents. In
divergence, at high levels they cause damage to cellular
constituents triggering oxidative stress. In either case, small
antioxidant molecules and enzymes modulate the action of these
ambivalent species.
