Catalase, a pivotal enzyme in plant antioxidative defense mechanisms, plays a crucial role
in detoxifying hydrogen peroxide, a reactive oxygen species (ROS). In this chapter, a …

Catalase (CAT, 1.11. 1.6) is an antioxidant enzyme present in all aerobic organisms. It is
known to catalyze H 2 O 2 into water and oxygen in an energy-efficient manner in the cells …

Adequate responses to environmental changes are crucial for plant growth and survival.
However, the molecular and biochemical mechanisms involved are poorly understood and …

Reactive oxygen species (ROS) are permanently generated in plastids, peroxisomes,
mitochondria, cytosol and apoplast, as toxic by-products of aerobic metabolism and/or as …

Abstract Reactive Oxygen Species (ROS) are a natural consequence of the aerobic
metabolism, and plants have mechanisms to deal with them in normal conditions, controlling …

Based on the origin, we can classify different types of stress. Environmental factors, such as
high light intensity, adverse temperature, drought, or soil salinity, are summarized as abiotic …

Plants have to counteract unavoidable stress-caused anomalies such as oxidative stress to
sustain their lives and serve heterotrophic organisms including humans. Among major …

Plants faced several biotic and abiotic stresses during its life span. For maintaining the
normal growth, plant produces the reactive oxygen species (ROS), which help in the …

Multiple abiotic stress conditions are known to trigger production of reactive oxygen species
such as hydrogen peroxide. Generally, the related antioxidative defense reactions including …

As an inevitable consequence of aerobic metabolism reactive oxygen species (ROS) are
continuously generated by partial reduction of molecular oxygen, thereby imposing oxidative …
