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.

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

Plants have a very specific and efficient mechanism to obtain, translocate and store nutrients from the surrounding environment. The precise mechanism that helps a plant in nutrient translocation from root to shoot also, in the same way, transfers and stores toxic metals within their structure. Metal toxicity generally causes multiple direct or indirect effects on plants, affecting nearly all of their physiological functions. Plant tolerance to heavy metals depends largely on plant efficiency in uptake, translocation and sequestration of heavy metals in specific cell organelles or specialized tissues. The main purpose of this book is to present a holistic view of the recent advancement in the field of accumulation and remediation using plants, the green solar powered alternative to ameliorate heavy metal from the polluted environment. The key features of the book are related to metal transporters and metal accumulation mechanisms under heavy metal stress in plants, plant transcriptional regulation and responses under metal contamination, multiple toxic metal contaminations and its phytoremediation approaches etc. Based on the advancement of research in recent years, the information compiled in this book will bring an in-depth knowledge on the bioaccumulation of metals, their transportation in natural conditions or genetically modified plants and their strategy to cope with the toxicity to survive in the hostile environment.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Following a description of the various sources and factors influencing the contents of heavy metal pollution in post-catastrophic and agricultural soils, subsequent chapters examine soil enzymes and eggs as bio-monitors, lead adsorption, the effects of arsenic on microbial diversity, and the effects of Mediterranean grasslands on abandoned mines. A third section focuses on the adaptation strategies used by plants and bacteria, such as Pinus sylvestris in industrial areas, and the rhizosphere in contaminated tropical soils and soil treated with sewage sludge. Further topics addressed include strategies of bioremediation, e.g. using transgenic plants as tools for soil remediation. This new volume on heavy metals in soil will be of interest to researchers and scholars in microbial and plant biotechnology, agriculture, the environmental sciences and soil ecology.

Phytoremediation is an exciting, new technology that utilizes metal-accumulating plants to rid soil of heavy metal and radionuclides. Hyperaccumulation plants are an appealing and economical alternative to current methods of soil recovery. Phytoremediation of Contaminated Soil and Water is the most thorough literary examination of the subject available today. The successful implementation of phytoremediation depends on identifying plant material that is well adapted to specific toxic sites. Gentle remediation is then applied in situ, or at the contamination site. No soil excavation or transport is necessary. This severely contains the potential risk of the pollutants entering the food chain. And it's cost effective. The progress of modern man has created many sites contaminated with heavy metals. The effected land is toxic to plants and animals , which creates considerable public interest in remediation. But the commonly used remedies are ex situ, which poses an expensive dilemma and an even greater threat. Phytoremediation offers the prospect of a cheaper and healthier way to deal with this problem. Read Phytoremediation of Contaminated Soil and Water to learn just how far this burgeoning technology has developed.
