Book Description
Many agricultural crops worldwide, especially in semi-arid climates, suffer from iron deficiencies. Among plants sensitive to iron deficiency are apples, avocado, bananas, barley, beans, citrus, cotton, grapes, peanuts, pecans, potatoes, sorghum, soybeans, and numerous ornamental plants. Deficiencies are usually recognized by chlorotic, in new leaves and are typically found among sensitive crops grown in calcareous or yellowed, interveinal areas soils which cover over 30% of the earth's land surface. Iron deficiency may lead, in extreme cases, to complete crop failure. In intensive agriculture on calcareous soils, iron often becomes a major limiting nutrient for optimal crop production, thus, correction of iron deficiency is required. Various chemicals and practices are available. They are, however, costly and do not always result in a complete remedy of the deficiency. Crucial questions relative to the cost-benefit equation such as the recovery rate of plants and the long-term fertilizing effect have not yet been resolved. The complexity of iron nutrition problems requires an understanding of the chemistry of iron oxides in soils, of the chemistry of both natural and synthetic chelates, of rhizosphere microbiology and biochemistry, and of the physiological involvement of the plant in iron uptake and transport.

Book Description
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Book Description
In the past few decades, it has been realized through research that fungal siderophores epitomize the uptake of iron as well as other essential elements like zinc, magnesium, copper, nickel and arsenic. Understanding the chemical structures of different fungal siderophores and the membrane receptors involved in uptake of mineral ions has opened new areas for research. In this edited volume, recent research is presented on fungal siderophores in one comprehensive volume to provide researchers a strong base for future research. Siderophores are the low molecular weight, high affinity iron-chelating compounds produced by bacteria and fungi. They are responsible for transporting iron across the cell membrane. Fungi produce a range of hydroxamate siderophores involved in the uptake of essential elements in almost all microorganisms and plants. In recent years, siderophores have been used in molecular imaging applications to visualize and understand cellular functions, which thus provide an opportunity to identify new drug targets. Therefore, knowledge of fungal siderophores has become vital in current research. Siderophores have received much attention in recent years because of their potential roles and applications in various research areas. Their significance in these applications is because siderophores have the ability to bind a variety of metals in addition to iron, and they have a wide range of chemical structures and specific properties. For instance, siderophores function as biocontrols, biosensors, and bioremediation and chelation agents, in addition to their important role in weathering soil minerals and enhancing plant growth. This book focuses on siderophores with the following significant points. It discusses leading, state-of-the-art research in all possible areas on fungal siderophores. The contributors are well-known and recognized authorities in the field of fungal siderophores. It discusses a projection of practical applications of fungal siderophores in various domains. This is the first book exclusively on fungal siderophores. In this comprehensive, edited volume, we show leading research on fungal siderophores and provide the most recent knowledge of researchers' work on siderophores. This book presents in-depth knowledge on siderophores to researchers working in areas of health sciences, microbiology, plant sciences, biotechnology, and bioinformatics.

Book Description
Iron Chelation in Plants and Soil Microorganisms provides an introduction to the basic biological processes of plants that require iron and those affected by iron deficiency. The book aims to stimulate research in the area of iron metabolism in plants and plant-associated microorganisms. The book is organized into three parts. Part I provides an overview of research methods used in the study of iron chelation relevant to plant biology. Key topics covered include microbial siderophores, phytosiderophores, and plant and microbial ferritins. Part II discusses the molecular approach to iron chelation, which includes molecular biology, enzymology, and iron uptake activities. Part III addresses various physiological and chemical characteristics of the iron stress response. This book was written for scientists involved in plant physiology, agronomy, phytopathology, plant control, and soil microbiology. It may also be of interest to those studying soil chemistry, plant-mineral relationships, horticulture, in vivo and in vitro iron measurements, and microbial ecology. In addition, the book can serve as reference for specialty courses and laboratories conducting research on iron nutrition in plants as well as individuals engaged in iron-related research.

Book Description
Iron is a major constituent of the earth crust. However, under alkaline conditions commonly found in arid and semi-arid environments iron becomes unavailable to plants. When plants are affected by a shortage of iron their leaves become yellow (chlorotic), and both plant growth and crop yield are reduced. The roots of plants affected by iron deficiency may develop a series of responses directed to improve iron uptake, such as increased proton excretion and iron reduction capabilities or excretion of iron chela tors called siderophores. Iron deficiency affects major crops worldwide, including some of major economic importance such as fruit trees and others. Correction of iron deficiency is usually implemented through costly application of synthetic chelates. Since these correction methods are very expensive, the competitivity of farmers is often reduced and iron deficiency may become a limiting factor for the maintenance, introduction or expansion of some crops. In spite of the many years devoted to the study of iron deficiency, the knowledge of iron deficiency in soils and plants is still fragmentary in many aspects. We have only incomplete information on the processes at the molecular level that make some plant species and cultivars unable to take and utilize iron from the soil, whereas other plants grow satisfactorily under the same conditions.
