Metal Toxicity And Tolerance In Plants And Animals

This volume provides a synthesis of recent work on evolutionary aspects of metal tolerance in plants. It presents contributions from scientists with a wide diversity of expertise. It covers the evolution of heavy metal tolerance in groups of plants, fungi, and protists. The book discusses the physiological, genetic and molecular aspects of metal tolerances. It deals with the evolution of populations in metal-contaminated environments. Several chapters include tolerance in animals in order to place the rest of the book on plants in proper perspective. This publication is an exciting addition for scientists with both applied and basic interest in metal toxicity and tolerance. It is of importance to those in vegetation ecology, land reclamation, agronomy, physiology, population ecology, ecological genetics, evolutionary biology and molecular biology.

The aim of this book is to give an overview of the most important aspects of physiological and biochemical basis for metal toxicity and tolerance in plants. The book is expected to serve as a reference to university and college teachers, students of plant sciences, environmental biology, environmental biotechnology, agriculture, horticulture, forestry, plant molecular biology, and genetics.

Comprehensive resource detailing the molecular mechanisms underlying heavy metal toxicity and tolerance in plants Heavy Metal Toxicity and Tolerance in Plants provides a comprehensive overview of the physiological, biochemical, and molecular basis of heavy metal tolerance and functional omics that allow for a deeper understanding of using heavy metal tolerance for deliberate manipulation of plants. Through the authors’ unique approach, the text enables researchers to develop strategies to enhance metal toxicity and deficiency tolerance as well as crop productivity under stressful conditions, in order to better utilize natural resources to ensure future food security. The text presents the basic knowledge of plant heavy metal/metalloid tolerance using modern approaches, including omics, nanotechnology, and genetic manipulation, and covers molecular breeding, genetic engineering, and approaches for high yield and quality under metal toxicity or deficiency stress conditions. With a collection of 26 chapters contributed by the leading experts in the fields surrounding heavy metal and metalloids toxicity and tolerance in crop plants, Heavy Metal Toxicity and Tolerance in Plants includes further information on: Advanced techniques in omics research in relation to heavy metals/metalloids toxicity and tolerance Heavy metals/metalloids in food crops and their implications for human health Molecular mechanisms of heavy metals/metalloids toxicity and tolerance in plants Molecular breeding approaches for reducing heavy metals load in the edible plant parts Hormonal regulation of heavy metals toxicity and tolerance Applications of nanotechnology for improving heavy metals stress tolerance Genetic engineering for heavy metals/metalloids stress tolerance in plants With comprehensive coverage of the subject, Heavy Metal Toxicity and Tolerance in Plants is an essential reference for researchers working on developing plants tolerant to metals/metalloids stress and effective strategies for reducing the risk of health hazards.

Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants’ responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

Plant Metal Interaction: Emerging Remediation Techniques covers different heavy metals and their effect on soils and plants, along with the remediation techniques currently available. As cultivable land is declining day-by-day as a result of increased metals in our soil and water, there is an urgent need to remediate these effects. This multi-contributed book is divided into four sections covering the whole of plant metal interactions, including heavy metals, approaches to alleviate heavy metal stress, microbial approaches to remove heavy metals, and phytoremediation. Provides an overview of the effect of different heavy metals on growth, biochemical reactions, and physiology of various plants Serves as a reference guide for available techniques, challenges, and possible solutions in heavy metal remediation Covers sustainable technologies in uptake and removal of heavy metals

Cadmium Toxicity and Tolerance in Plants: Agronomic, Genetic, Molecular and Omic Approaches presents research and latest developments on mechanisms of cadmium tolerance covering both lab and field conditions. This book contains important insights and options for minimizing Cd accumulation in plants and mitigating Cd toxicity. Topics covered include using various omics approaches to understanding plant responses to Cd, novel technologies for developing Cd tolerance and integrated breeding approaches to mitigate Cd stress in crops. Cadmium Toxicity and Tolerance in Plants: Agronomic, Genetic, Molecular and Omic Approaches is a valuable resource for both researchers and students working on cadmium pollution and plant responses as well as related fields of environmental contamination and toxicology. Provides data on mechanisms of cadmium tolerance at the cell, organ and whole plant level Covers several major approaches, molecular and agronomic, in addressing cadmium toxicity in plants and soil Offers real-world, application focused techniques

This title focuses on the many aspects of the interaction between plants and heavy metals. Not only it describes the effects of heavy metal toxicity on the plant cell and its organs but it also examines the mechanisms that plants adopt to scavenge heavy metals at cellular, physiological, and metabolic level. Plants and Heavy Metals also analyses Hyperaccumulator plants and shows their potential role in phytoremediation technologies in light of the recent research results.
