Fully covers the biology, biochemistry, genetics, and genomics of Medicago truncatula Model plant species are valuable not only because they lead to discoveries in basic biology, but also because they provide resources that facilitate translational biology to improve crops of economic importance. Plant scientists are drawn to models because of their ease of manipulation, simple genome organization, rapid life cycles, and the availability of multiple genetic and genomic tools. This reference provides comprehensive coverage of the Model Legume Medicago truncatula. It features review chapters as well as research chapters describing experiments carried out by the authors with clear materials and methods. Most of the chapters utilize advanced molecular techniques and biochemical analyses to approach a variety of aspects of the Model. The Model Legume Medicago truncatula starts with an examination of M. truncatula plant development; biosynthesis of natural products; stress and M. truncatula; and the M. truncatula-Sinorhizobium meliloti symbiosis. Symbiosis of Medicago truncatula with arbuscular mycorrhiza comes next, followed by chapters on the common symbiotic signaling pathway (CSSP or SYM) and infection events in the Rhizobium-legume symbiosis. Other sections look at hormones and the rhizobial and mycorrhizal symbioses; autoregulation of nodule numbers (AON) in M. truncatula; Medicago truncatula databases and computer programs; and more.

Book Description
Metal and Nutrient Transporters in Abiotic Stress focuses on the different forms of environmental stress related to heavy metal, metalloid and nutrient deficiency that have the potential to inflict major damages to crop plants, leading to a massive decrease in crop yield and productivity. The book presents the current state of knowledge of the biochemical and molecular regulation of several classes of membrane transporters related to the uptake of metals/metalloids and nutrient elements during different stresses and their probable mechanisms of operation in plant stress tolerance. Metal and Nutrient Transporters in Abiotic Stress provides a comprehensive discussion that will help in mitigating multiple forms of stresses utilizing transporter proteins. Edited by leading experts and written by a global team of knowledgeable contributors, this book will further stimulate research in the field of transporter proteins and will foster further interests for researchers, academicians and scientists worldwide. It is complimented by its companion book titled Transporters and Plant Osmotic Stress. Focuses exclusively on metal and nutrient transporters involved in multiple environmental stresses in plants Explains exploiting transporters in crop improvement programs through transgenic technology against different stresses such as heavy metal, metalloid and nutrient deficiency Serves as an important source of information in the field of abiotic stress

Book Description
Metal ions are critical nutrients, yet overaccumulation of these same metals can also be toxic. To maintain appropriate intracellular levels, cells require specific metal uptake systems that are subject to precise homeostatic regulation. The long-range goal of our research is to define the molecular mechanism(s) and regulation of metal ion uptake in eukaryotic cells. Integrating genetic, molecular biological and biochemical approaches, we have examined these processes in the yeast Saccharomyces cerevisiae and the plant Arabidopsis thaliana. Both are proven model systems for studying fundamental cellular processes. Our work has focused on the ZIP family of metal transporters which we identified; this family has representatives in bacteria, fungi, plants and animals. IRT1, one of the founding members of the ZIP family, is an essential cation transporter that is expressed in the epidermal cells of iron deficient plant roots and is responsible for uptake of iron from the soil. We now know that t here are 15 ZIP genes in the Arabidopsis genome which can be divided into four different classes, based on their intron/exon arrangements and the similarities among their encoded gene products. The ZIP family members display different substrate specificities for metals and different tissue distributions in Arabidopsis. Moreover, the family members respond differentially to metal deficiencies. For example, IRT1, ZIP6 and ZIP9 mRNA are expressed mainly in the roots of iron deficient plants whereas ZIP4 responds to both iron and zinc deficiency. Work in both yeast and Arabidopsis has addressed substrate specificity as well as how these transporters are regulated in response to metal availability. Our project was broken down into four specific aims. Significant progress was made on all four aims. I have listed the publications which have resulted under the relevant specific aim.

Book Description
Plants are composed of 17 essential and at least 5 beneficial elements, and these must be taken up as metal or nutrient ions to allow for growth and cell division. Much effort has been devoted to studying the physiology and biochemistry of metals and nutrients in plants. The aspect of cell biology, however, is an emerging new field and much needs to be learned about sensing, long-distance communication within plants, and cellular signal transduction chains in response to environmental stress. Cellular malfunction and consequently disease result when any of the key steps in metal and nutrient homeostasis are disrupted. Working together, leading experts in their respective fields provide a new concept that reaches beyond plant nutrition and plasmalemma transport into cellular physiology. Each chapter contains basic information on uptake, physiological function, deficiency and toxicity syndromes, long-distance and intracellular transport. The discussion is devoted to metals and nutrients where recent progress has been made and highlights the aspects of homeostasis and sensing, signaling and regulation, drawing parallels to other organisms including humans. Finally, the book identifies gaps in our current knowledge and lays out future research directions.

Book Description
Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils. The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on contaminated soils; the phytoremediation of contaminated soils; tolerance, accumulation and detoxification mechanisms of zinc, copper, arsenic, cadmium and vanadium in plants; the critical role of sulfur metabolism in heavy metal tolerance; the role of aquatic macrophytes, plant growth-promoting bacteria, sugar crops and earthworms in detoxification; and heavy metal stabilization by promoting zeolite synthesis in soils.

Book Description
Environmental pollutants have become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation have resulted in indiscriminate exploitation of natural resources for fulfilling the human desires and needs, which have contributed in disturbing the ecological balance on which the quality of environment depends. The modern technological advancements in chemical processes/operations have been raised to new products and also new pollutants in abundant level which are above the self cleaning capacity of the environment. One of the major issues in present times is the threat to human lives, due to the progressive deterioration of the environment. This book discusses bioremediation technology-based remediation to restore contaminated sites and protect the environment. It studies the opportunities for more efficient biological processes in molecular biology and ecology. Notable accomplishments of these studies include the cleaning up of polluted water and contaminated land. The book includes invited papers by eminent contributors who provide cost-effective bioremediation strategies to immobilize contaminants for cleanup of environment. The book is directed towards postgraduate students in biotechnology/life sciences/environmental sciences/biosciences and researchers in universities and research institutes and industries.
