Book Description
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 Description
Major portion of the planet earth is covered by seas and oceans representing 96.5% of the planet’s water, playing a detrimental role in sustaining the plant including crop diversity and productivity for human consumption. Water resources contain both soluble and transition metals, which are easily absorbed by plants through roots as a first point of contact and subsequently play important physiological and biological functions in plants. Transition metals such as copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) contribute to the plant productivity by playing key functional roles in the photosynthesis. In addition, to their major role in regulating the plant productivity, they also play an important role by acting as homeostatic regulators in uni-parentally inherited chloroplasts and maintains the flow of the electron transfer. It is worthwhile to mention that they play a critical role as transporters, which acts as electron balancing units for managing the electrostatic potential across the membranes. In contrast, some metals such as Cd, As play a significant role in inducing the stress mechanism and influencing either directly or in-directly Haber-Weiss reactions either through the production of the reactive oxygen species (ROS) or through the membrane damage thus leading to leakage of membrane transporters. However, besides playing a detrimental role as transporters in plant system, excessive accumulation of these metals due to the increasing contamination in the marginal soil and water are posing important threats to the plant system. Realizing the toxic effects of the metals, several physiological evidences have been laid for the credence of the metal toxicity and their concurrent effect on plant productivity. Increasing effects of the metals as toxicants can have three adverse effects on the populations: population can move, persist via local adaptation or phenotypic plasticity, or die. Next generation sequencing studies have revolutionized our abilities to detect the changes in expression profiles across an array of genes, which can in-turn help to develop early markers of metal induced stress. Plant Metallomics and Functional Omics: A System-Wide Perspective focuses on the applications of the system wide understanding of the biological and functional interplay occurring at the juncture of the metalloid induced stress and toxicity. The main goal of this book is to familiarize the readers with the most up-to-date information on metal-induced physiological changes in plant species.

Book Description
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.

Book Description
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.
