Book Description
This book covers many facets of plant selenium (Se) accumulation: molecular genetics, biochemistry, physiology, and ecological and evolutionary aspects. Broader impacts and applications of plant Se accumulation also receive attention. Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se. Selenium in plants has profound ecological impact, and likely contributes to Se movement in ecosystems and global Se cycling.

Book Description
This book focuses on selenium (Se) metabolism in plants. It not only covers plant genetic, biochemical and physiological processes but places these in the context of Se movement in the food chain and the global environment, as well as discusses ecological and evolutionary significance. While Se is an essential micronutrient, it is toxic at high levels, and there is a narrow window between Se adequacy and toxicity. More than a billion people and their livestock in low-Se regions have been estimated to be affected by Se deficiency, which compromises the immune system, thyroid activity, male fertility and mental function. In high-Se areas, Se toxicity is a problem. Selenium-accumulating plants may be used to alleviate Se deficiency in consumers (biofortification), or to remove environmental Se pollution (phytoremediation), both covered extensively in this volume. Plant species genetically vary in Se uptake, metabolism and tolerance. Some plants native to seleniferous soils can even hyperaccumulate Se up to 1.5% of their dry weight. The book reviews the latest knowledge about the processes involved in Se uptake, metabolism, tolerance and (hyper)accumulation, as well as successful approaches to optimize Se accumulation and speciation via classical crop breeding and genetic engineering. Global processes that control Se distribution and movement are reviewed, as are associated deficiency and toxicity issues. Relevant for Se bioavailability and for Se movement in the food chain, Se metabolism is also reviewed in prokaryotes and in mammalian consumers, and the nutritional benefits of plant Se on consumers are discussed. The reader will learn about the profound ecological effects of plant Se on interactions with herbivores, pollinators, microbes and other plants, and the likely selection pressures that drive the evolution of Se hyperaccumulation.

Book Description
A close examination of current research on abiotic stresses in various plant species The unpredictable environmental stress conditions associated with climate change are significant challenges to global food security, crop productivity, and agricultural sustainability. Rapid population growth and diminishing resources necessitate the development of crops that can adapt to environmental extremities. Although significant advancements have been made in developing plants through improved crop breeding practices and genetic manipulation, further research is necessary to understand how genes and metabolites for stress tolerance are modulated, and how cross-talk and regulators can be tuned to achieve stress tolerance. Molecular Plant Abiotic Stress: Biology and Biotechnology is an extensive investigation of the various forms of abiotic stresses encountered in plants, and susceptibility or tolerance mechanisms found in different plant species. In-depth examination of morphological, anatomical, biochemical, molecular and gene expression levels enables plant scientists to identify the different pathways and signaling cascades involved in stress response. This timely book: Covers a wide range of abiotic stresses in multiple plant species Provides researchers and scientists with transgenic strategies to overcome stress tolerances in several plant species Compiles the most recent research and up-to-date data on stress tolerance Examines both selective breeding and genetic engineering approaches to improving plant stress tolerances Written and edited by prominent scientists and researchers from across the globe Molecular Plant Abiotic Stress: Biology and Biotechnology is a valuable source of information for students, academics, scientists, researchers, and industry professionals in fields including agriculture, botany, molecular biology, biochemistry and biotechnology, and plant physiology.

Book Description
The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Book Description
Selenium plays a significant role in preventing certain types of cancer and cardiovascular diseases. The level of Selenium in the human body depends on its concentration in food. In turn, the content in vegetable crops is a function of the soil-plant system. There are many countries in the world with low Selenium content in the soil. The average daily human intake is thus limited through food chain. Analysis of Selenium status suggests that fortification of the soil substrate with Sodium Selenate, and foliar application to agricultural crops are both effective means of Selenium enrichment. Our intention for this publication is to present the possibilities of augmenting Selenium content by biofortification of soils and plants through differentiated nutrition. In the first part of the monograph, the results of Selenium supplementation in model vegetation experiments are presented. The next part of the monograph presents the results of foliar supplementation of Selenium in field conditions. This book is an outstanding reference source for plant breeders and researchers engaged in biofortification of horticulture crops. It is also beneficial to agricultural companies and other stakeholders.
