Book Description
This book focuses on the menace of metal pollution and its impact on plants, particularly food grains, pulse and vegetable plants covering morphological, anatomical, physiological and biochemical aspects. It includes comparative studies among metal hyper-accumulators (metallophytes) and non-accumulators including exogenous hormonal alleviation in them due to metal stress. Low dose stimulation effects are also reviewed. The most significant feature of the book is its extensive coverage of genomics, metabolomics, ionomics, proteomics and transcriptomics in metal non-hyper-accumulators and hyper-accumulators. Being an edited volume, the book incorporates a variety of research perspectives, enhancing the existing knowledge about metal pollution and points to newer avenues to be researched.

Book Description
In recent years, heavy metals have been widely used in agricultural, chemical, domestic, and technological applications, causing environmental and soil contaminations. Heavy metals enter the plant system through soil or via the atmosphere, and can accumulate, affecting physiological processes, plant growth, yield, and human health if heavy metals are stored in edible tissues. Understanding the regulation mechanisms of plant heavy metals accumulation and partitioning is important to improve the safety of the food chain. In this Special Issue book, a total of 19 articles were included; four reviews covering phytoremediation, manganese phytotoxicity in plants, the effect of cadmium on plant development, the genetic characteristics of Cd accumulation, and the research status of genes and QTLs in rice, respectively, as well as fifteen original research articles, mainly regarding the impact of cadmium on plants. Cadmium was therefore the predominant topic of this Special Issue, increasing the attention of the research community on the negative impacts determined by cadmium or cadmium associated with other heavy metals. The articles have highlighted a great genetic variability, suggesting different possibilities for accumulation, translocation and the reduction or control of heavy metal toxicity in plants.

Book Description
Environmental stresses represent the most limiting factors for agricultural productivity. Apart from biotic stress caused by plant pathogens, there are a number of abiotic stresses such as extremes in temperature, drought, salinity, heavy metals and radiation which all have detrimental effects on plant growth and yield. However, certain plant species and ecotypes have developed various mechanisms to adapt to such stress conditions. Recent advances in the understanding of these abiotic stress responses provided the impetus for compiling up-to-date reviews discussing all relevant topics in abiotic stress signaling of plants in a single volume. Topical reviews were prepared by selected experts and contain an introduction, discussion of the state of the art and important future tasks of the particular fields.

Book Description
Plant growth and development is closely dependent on the plant environment, including the wide-spread presence of organic and inorganic xenobiotics and pollutants. Currently, heavy metals are the most common inorganic environmental pollutants and they have pronounced effects and consequences not only for plants, but also for the ecosystem in which the plants form an integral component. It has been suggested that these contaminants accumulate in agricultural crops, thus entering the food chain and posing a significant health risk. Plants growing in polluted sites exhibit altered metabolism, reduced growth, and decreased biomass production. These pollutants adhere to plant roots and exert physical or chemical toxicity and subsequently cell death in plants. Yet, plants have developed various defence mechanisms to counteract the toxicity induced by heavy metals. Only detailed study of the processes and mechanisms would allow researchers and students to understand the interactions, responses, and adaptations of plants to these pollutants; however, there are several unresolved issues and challenges regarding the interaction and biological effects of heavy metals. Therefore, this volume provides relevant, state-of-the-art findings on environmental phytotoxicity and the mechanisms of such interactions at the cellular and molecular levels. This volume consists of chapters on relevant topics contributed by different experts or group of experts so as to make available a comprehensive treatise designed to provide an in-depth analysis of heavy metals phytotoxicity. This book may serve as a reference to scientists, researchers and students in the fields of toxicology, environmental toxicology, phytotoxicology, plant biology, plant physiology, plant biochemistry and plant molecular biology, and especially those interested in heavy metals toxicology.

Book Description
Metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, nutritional, and environmental reasons. These pollutants, ultimately derived from a growing number of diverse anthropogenic sources (industrial effluents and wastes, urban runoff, sewage treatment plants, boating activities, agricultural fungicide runoff, domestic garbage dumps, and mining operations), have progressively affected more and more different ecosystems. Even agricultural lands are progressively becoming enriched of metals due to long-term use of phosphatic fertilizers, sewage sludge application, dust from smelters, industrial waste and bad watering practices in agricultural lands. Among these metals, Cu, Fe, Mn, Mo and Zn are pivotal micronutrients, while Ag, As, Cd, Cr, Hg, Pb, Sb and V and are non-essential for plants and have no known function as nutrients and seem to be more or less toxic to all plants and microorganisms. Sodium excess deserves particular attention. Several agricultural lands are indeed becoming familiar with the problem of salinization, due to the use of fresh water which contains a high level of NaCl or due to intensive fertilization, especially in arid and semi-arid environments characterized by poor rainfalls. Overall, the presence of both essential and non-essential metals in the atmosphere, soil and water, in excessive amounts, can cause serious problems to all organisms. Knowledge of plant-metal interactions is important for the safety of the environment, but also for reducing the risks associated with the introduction of trace metals into the food chain. Although intense research has been conducted during the last 30 years, many aspects remain to be clarified concerning the effect of metals in higher plants. Our goal for this book is to critically review existing literature related to the specific effects of different metals in plants, as well as to provide new evidence about plant-metal interactions in order to clarify mechanisms of metal uptake, translocation, and partitioning and the effect of metal toxicity. Consequences related to accumulation of metals in food products have been described. Physiological and biochemical mechanisms adopted by plants to cope with metal excess and possible implications for phytoremediation of metal-contaminated soils are also discussed. Therefore, we believe that this book will provide a comprehensive overview regarding some aspects of metal toxicity in plants and it will be useful for scientist working in this field of research, but it will also be of practical interest to environmentalists, policy-makers, and resource managers working on the topic. We wish to thank all the authors who joined this book project by contributing their valuable work. Lastly, we extend our sincere thanks to Nova Science Publishers for their efficient support.
