Book Description
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 Description
Understanding metalloids and the potential impact they can have upon crop success or failure Metalloids have a complex relationship with plant life. Exhibiting a combination of metal and non-metal characteristics, this small group of elements – which includes boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te) – may hinder or enhance the growth and survival of crops. The causes underlying the effects that different metalloids may have upon certain plants range from genetic variance to anatomical factors, the complexities of which can pose a challenge to botanists and agriculturalists of all backgrounds. With Metalloids in Plants, a group of leading plant scientists present a complete guide to the beneficial and adverse impacts of metalloids at morphological, anatomical, biochemical, and molecular levels. Insightful analysis of data on genetic regulation helps to inform the optimization of farming, indicating how one may boost the uptake of beneficial metalloids and reduce the influence of toxic ones. Contained within this essential new text, there are: Expert analyses of the role of metalloids in plants, covering their benefits as well as their adverse effects Explanations of the physiological, biochemical, and genetic factors at play in plant uptake of metalloids Outlines of the breeding and genetic engineering techniques involved in the generation of resistant crops Written for students and professionals in the fields of agriculture, botany, molecular biology, and biotechnology, Metalloids in Plants is an invaluable overview of the relationship between crops and these unusual elements.

Book Description
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.

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
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.
