Book Synopsis Metal Toxicity in Plants: Perception, Signaling and Remediation by : Dharmendra K. Gupta

Download or read book Metal Toxicity in Plants: Perception, Signaling and Remediation written by Dharmendra K. Gupta. This book was released on 2011-09-15. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metal accumulation in soil and water from natural sources or anthropogenic activities have produced severe environmental contamination in some parts of the world due to the persistence of metals in the environment by their accumulation throughout the food chain. The purpose of this book is to present the most recent advances in this field, mainly concerning the uptake and translocation of heavy metals in plants, mechanisms of toxicity, perception of metal and regulation of cell response under metal stress. Another key feature of this book is related to the studies on signaling and remediation processes in recent years, which have taken advantage of recent technological advances including "omic" approaches. In recent years transcriptomic, proteomic and metabolomic studies have become very important tools for analyzing both the dynamics of changes in gene expression and the profiles of protein and metabolites under heavy metal stress. This information is also very useful for plotting the complex signaling and metabolic network induced by heavy metals, in which hormones and reactive oxygen species (ROS) also play an important role. Understanding the mechanism involved in sequestration and hyperaccumulation is very important to developing new strategies of phytoremediation, which are reviewed in several chapters of this book. The information included yields very stimulating insights into the mechanism involved in the regulation of plant responses to heavy metals, which in turn improve our knowledge of cell regulation under metal stress and the use of plants for phytoremediation.

Book Synopsis Plants Under Metal and Metalloid Stress by : Mirza Hasanuzzaman

Download or read book Plants Under Metal and Metalloid Stress written by Mirza Hasanuzzaman. This book was released on 2018-11-30. Available in PDF, EPUB and Kindle. Book excerpt: In the industrial era, the most important potential threat to crop production is abiotic stress, including toxic metal/metalloid stress. Growing populations and rapid industrialization lead to the generation and release of huge amounts of toxic metals/metalloids into the environment, altering plant physiological processes and reducing yields. In the last few decades, there has been extensive research to elucidate the mechanisms of tolerance to metal/metalloid toxicity and ways to improve the defense system in plants. Use of exogenous photoprotectants such as osmoprotectants, plant nutrients, phytohormones, signaling molecules, antioxidants, amino acids and organic acids are widely being used to improve plants’ tolerance to metal/metalloid stress. Recently, phytoremediation approaches have been effectively employed to remediate metal/metalloid pollution. This book presents the latest insights into plant responses and tolerance in plants grown under metal/metalloids stress to provide a better understanding of the topic and the future outlook.

Book Synopsis Heavy Metal Stress in Plants by : Dharmendra K. Gupta

Download or read book Heavy Metal Stress in Plants written by Dharmendra K. Gupta. This book was released on 2013-08-04. Available in PDF, EPUB and Kindle. Book excerpt: Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. Metal toxicity causes multiple direct and indirect effects in plants that concern practically all physiological functions. The main purpose of this book is to present comprehensive and concise information on recent advances in the field of metal transport and how genetic diversity affects heavy metal transport in plants. Other key futures of the book are related to metal toxicity and detoxification mechanisms, biochemical tools for HM remediation processes, molecular mechanisms for HM detoxification, how metallomics and metalloproteomics are affected by heavy metal stress in plants, and the role of ROS metabolism in the alleviation of heavy metals. Some chapters also focus on recent developments in the field of phytoremediation. Overall the book presents in-depth information and the most essential advances in the field of heavy metal toxicity in plants in recent years.

Book Synopsis Heavy Metal Toxicity: Environmental Concerns, Remediation and Opportunities by : Rajeev Pratap Singh

Download or read book Heavy Metal Toxicity: Environmental Concerns, Remediation and Opportunities written by Rajeev Pratap Singh. This book was released on 2023-10-24. Available in PDF, EPUB and Kindle. Book excerpt: This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.
