Available in PDF, EPUB and Kindle. Book excerpt: In many parts of the world, soil and water are slightly to moderately contaminated with metals and metalloids such as Cd, Cu, Zn, Ni, Co, Cr, Pb, Si, B and As. This could be due to long-term use of phosphatic fertilizers, sewage sludge application, dust from smelters, industrial waste and bad watering practices in agricultural lands. Beside natural factors, human activities have contributed to the enormous increase in heavy metal and/or metalloid pollution in the environment. Metal and metalloid stress are major abiotic stress factors that limit crop production and reduce agricultural yield. The primary response of plants is the generation of reactive oxygen species (ROS) upon exposure to high levels of metals/metalloids. They either generate ROS directly through Haber-Weiss reactions or overproduction of ROS and occurrence of oxidative stress in plants could be the indirect consequence of metals/metalloids toxicity. The indirect mechanisms include their interaction with the antioxidant system, disrupting the electron transport chain or disturbing the metabolism of essential elements. One of the most deleterious effects induced by heavy metals exposure in plants is lipid peroxidation, which can directly cause biomembrane deterioration. The impact of metals/metalloids on plant water relations has to be distinguished from their effects on water availability in soils, on root growth, limiting water uptake, as well as other phytotoxic effects. If soils are high in soluble salts (including heavy metal salts), the osmotic potential in the soil solution might be lower than the potential of the cell sap in root. Under these circumstances, the soil solution would severely restrict the rate of water uptake by plants and lead to osmotic stress. Further, the negative influence metals/metalloids have on the growth and activities of soil microorganisms, may also indirectly affect the growth of plants. In the book “Metals and Metalloids in Plant Signaling”, we elucidated the effects of metals/metalloids on signaling and communication cascades in plants. The general aim of the present book is to provide a comprehensive analysis of the current situation and development in the field and to develop a science-based theoretical foundation for the conceptualization, and practical application. The various chapters are based on the consideration of metals/metalloids in terms of their action on different regulatory and functional systems of plants (signaling, metabolism, uptake, and transport mechanisms, etc.).
Download or read book Plants Under Metal and Metalloid Stress written by Mirza Hasanuzzaman and published by Springer. This book was released on 2018-11-30 with total page 424 pages. 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.

Download or read book Metal Toxicity in Plants Perception Signaling and Remediation written by Dharmendra K. Gupta and published by Springer Science & Business Media. This book was released on 2011-09-15 with total page 268 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arsenic, lead, and cadmium are among the EPA's highest priority hazardous substances for research and remediation. These toxic elements are high priorities due to extensive soil and water contamination, and extreme impact on human health, including increased cancer rates, liver disease, respiratory disorders, and learning disabilities. As part of my dissertation work I have investigated heavy metal and metalloid uptake, movement, accumulation, and signaling responses in plants at three different levels. First, I pursued a basic science project using a forward genetic screen to identify new components in the heavy metal and arsenic transcriptional response network. I identified At4g10930 and At4g13575 as likely genes to contain the causative mutation in a mutant Arabidopsis line that displayed a constitutive cadmium response (crc1), and identified a candidate region and 25 candidate mutations for a super-response to cadmium (src1) mutant. In a more translational research project, I generated transgenic Arabidopsis expressing known heavy metal and arsenic detoxification machinery driven by a root specific promoter. These transgenic Arabidopsis lines may provide a proof of concept for manipulating spatial sequestration of heavy metals and arsenic in order to minimize contamination of aerial, often edible, tissues in crops. We are also working to generate transgenic rice utilizing the same concept to minimize heavy metal and metalloid storage in the grain. Lastly, I worked on a community outreach project monitoring heavy metal and arsenic accumulation in food plants grown at a community garden in Southeastern San Diego in collaboration with Dr. Keith Pezzoli, the head of the Community Engagement and Research Translation Cores (CEC/RTC) of the UCSD Superfund. As part of this project longitudinal tracking of heavy metal and arsenic accumulation was done in edible and non-edible fruit tree tissue. Lead accumulation was found in leaf tissue of several fruit trees, however no detectable accumulation was found in fruit samples. Additionally, heavy metals and arsenic accumulation in a number of ground grown plant samples, which led to the incorporation of raised beds at the Ocean View Growing Grounds, mitigating this potential exposure risk.

Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.
