When plants are subjected to environmental stress conditions such as high light intensity, temperature extremes, drought high salinity, herbicide treatment or mineral deficiencies, the balance between the production of reactive oxygen species and the quenching activity of the antioxidants is upset, often resulting in oxidative damage. Oxidative damage to plants effects the overall production of the crop. To understand the effect of different environmental stresses it is essential to learn about the generation and quenching mechanism of the ROS. This volume gives the in-depth knowledge about how ROS is generated what are its effects on biomolecules and how the crop productivity is affected and what are the mechanism of defense.
This book also shows how transgenic approaches help us to protect the plants from environmental stresses without any effect on the crop productivity. Phytohormones, which are very essential for the growth and development of the plant have also been shown to minimize the oxidative stress in plants. How the stress is sensed by the plant is also described in this volume as signaling pathways during salt stress. Heavy metals are easily taken up by plants and enters the food chain, causing serious health disorders in humans. This volume also cover the effect of different heavy metals on plants and their ability to sustain in such an environment. The volume also considers the role of mycorrhizal associations in alleviating the oxidative stress. Role of potassium in abating moisture stress is also highlighted in this volume.
This volume provides invaluable information about the role of antioxidants in alleviating oxidative stress and will be very useful for biologists working on stress physiology. The volume is very much beneficial for the students, research scholars, plant physiologists and phytochemists of different research institutes and universities in India and abroad.
