Antioxidant Defense in Plants: Molecular Basis of Regulation

This edited book discusses the molecular mechanisms of antioxidants in plants, defense mechanisms, and adaptation strategies to environmental stresses. It highlights the role of gene expression,omics, and CRISPR-Cas mediated genome editing in defense-related studies. Antioxidants scavenge excess ROS and improve stress tolerance, making it essential to understand their efficiency for plant adaptation.

This edited book delves into the intricate molecular mechanisms underlying diverse enzymatic and non-enzymatic antioxidants, defense systems, and adaptation strategies employed by plants to withstand challenging environmental conditions. It emphasizes the role of gene expression, genomics, and cutting-edge technologies like CRISPR-Cas-mediated genome editing in studying defense-related studies in plants. Environmental stresses, such as drought, salinity, or floods, generate reactive oxygen species (ROS) that severely damage cell membrane integrity by promoting lipid peroxidation. To counteract these harmful effects, plants possess an intricate and vibrant antioxidant defense system comprising both enzymatic and non-enzymatic antioxidants. These antioxidants include catalase, peroxidase, superoxide dismutase, glutathione reductase, glutathione S-transferase, guaiacol peroxidase, monodehydroascorbate reductase, and dehydroascorbate reductase, among others. Additionally, plants rely on glutathione, ascorbate, α-tocopherol, carotenoids, and flavonoids as non-enzymatic antioxidants to scavenge and reduce excess ROS, thereby enhancing their tolerance to various stresses. Stress tolerance in most crop plants is strongly correlated with the efficiency of their antioxidant defense systems. Consequently, understanding the effectiveness of these defense mechanisms is crucial for facilitating plants' ability to adapt to challenging environments. This book appeals to a wide audience, including teachers, researchers, and academic experts. It also serves as valuable supplementary reading material for undergraduate and graduate students pursuing biotechnology and molecular biology of plants.
