Available in PDF, EPUB and Kindle. Book excerpt: Due to the consequences of urbanization and industrialization, heavy metal contamination in the environment is a world wide problem, threatening to the plants, animals, and human beings. Most heavy metals occur naturally in soils as trace elements, the biota-require some of these elements as essential micronutrients. These heavy metals at their higher concentrations, found toxic in living organisms. Their release into the environment in biologically available forms, as a result of human activity, may damage or alter both natural and man-made ecosystems. The most obvious sources of metal pollution are the process of extraction and purification, mining, smelting and refining, use of metal containing agricultural sprays, pesticides, fertilizers, industrial effluents, automobile combustion, municipal incinerators, sewage sludge and industrial effluents etc. The soils derived from ultra-basic igneous rocks, particularly serpentine, contain high nickel content. There is greater concern about nickel toxicity in crop plants regarding, for example, the application of sewage sludge (Pandey, 2006), which is often high in nickel.

Book excerpt: A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book. This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.

Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Download or read book Accumulation of Zinc and Its Role in Plant Defence written by Samuel Valbonesi and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The elemental defence hypothesis was first put forward by Boyd and Martens in 1992. It suggested that plants concentrate high levels of heavy metals into their biomass to act as a defence against herbivory. This thesis focused on testing this theory using zinc (Zn) as the accumulated element. Several plant species, including T. caerulescens, are known as hyperaccumulators of Zn and can contain concentrations greater than 10,000 mg kg-1. The research used a novel technique to assess the levels of Zn in this plant species in the field. Other plant species, which contain more than 2000 mg Zn kg-1 but less than hyperaccumulators, are known as accumulators. They have received increased amounts of attention because research has shown that these concentrations can still have a negative impact on herbivores (Coleman et al., 2005). One of these accumulators, B. juncea, is a fast growing species, well suited to test the defensive qualities of Zn against herbivores and so was the focus of the rest of the thesis. B. juncea was tested to see if the uptake of Zn was inducible by assessing if there was an increased uptake of Zn after plants were subjected to attack by the herbivore H. aspersa. Previous research (Hodge et al, 2000) has shown that many plants are capable of increasing their concentration of defence compounds following herbivore attack. However, damage did not increase Zn uptake in B. juncea, so this elemental defence does not appear to be inducible. The preference and performance of herbivores (juvenile and adult H. aspersa and larvae of P. brassicae) on leaves of B. juncea containing high and low concentrations of Zn was tested. It found that the growth rate of both juvenile snails and larvae of P. brassicae was reduced by a diet of leaves high in Zn concentration and both species selected leaves low in Zn in preference tests, suggesting that Zn is an effective defence. In the final experimental chapter, the thesis evaluates the defensive properties of Zn in B. juncea plants grown in the field. In contrast to the earlier experiments, this field experiment found that plants containing elevated concentrations of Zn were significantly more damaged than those that had been grown on a control treatment, a result which goes against the elemental defence hypothesis. The thesis concludes by suggesting that although increased concentrations of Zn may have an impact on the growth and behaviour of herbivores in the laboratory, these effects do not necessarily occur under field conditions.

Available in PDF, EPUB and Kindle. Book excerpt: This second and expanded edition of the first book on agromining (phytomining) presents a comprehensive overview of the metal farming & recovery of the agromining production chain. Agromining is an emerging technology that aims to transform the extraction of sources of target elements not accessible by traditional mining and processing techniques. Agromining, which is based on sustainable development, uses hyperaccumulator plants as 'metal crops' farmed on sub-economic soils or minerals wastes to obtain valuable target elements. This volume is edited and authored by the pioneers in the rapidly expanding field of agromining and presents the latest insights and developments in the field. This book provides in-depth information on the global distribution and ecology of hyperaccumulator plants, their biogeochemical pathways, the influence of rhizosphere microbes, the physiology and molecular biology of hyperaccumulation, as well as aspects of propagation and conservation of these unusual plants. It describes the agronomy of metal crops and opportunities for incorporating agromining into rehabilitation and mine closure, including test cases for agromining of nickel, cobalt, manganese, arsenic, selenium, cadmium, zinc, thallium, rare earth elements and platinum group elements. Since the first edition was published, there have successful nickel agromining field trials in the tropics (in Malaysia and Guatemala), and these are presented in a dedicated case study chapter. Other new chapters focus on the processing of bio-ore for elements other than nickel, such as rare earth elements and cadmium, and on agromining from industrial wastes such as tailings, and industrial by-products and sites. Furthermore, the book features two new chapters that provide a comprehensive assessment of accumulation a very wide range elements from the Periodic Table in various plant species around the globe, and a chapter on practical methods for discovery of hyperaccumulator plant species in the field and in the herbarium. This book is of interest to environmental professionals in the minerals industry, government regulators, and academics.
