Seeds provide an efficient means in disseminating plant virus and viroid diseases. The success of modern agriculture depends on pathogen free seed with high yielding character and in turn disease management. There is a serious scientific concern about the transmission of plant viruses sexually through seed and asexually through plant propagules. The present book provides the latest information along with the total list of seed transmitted virus and viroid diseases at global level including, the yield losses, diagnostic techniques, mechanism of seed transmission, epidemiology and virus disease management aspects. Additional information is also provided on the transmission of plant virus and virus-like diseases through vegetative propagules. It is also well known that seed transmitted viruses are introduced into new countries and continents during large-scale traffic movements through infected germplasm and plant propogules. The latest diagnostic molecular techniques in different virus-host combinations along with disease management measures have been included. The book shall be a good reference source and also a text book to the research scientists, teachers, students of plant pathology, agriculture, horticulture, life sciences, green house managers, professional entrepreneurs, persons involved in quarantines and seed companies. This book has several important features of seed transmitted virus diseases and is a good informative source and thus deserves a place in almost all university libraries, seed companies and research organizations.

Soils would not exist without the complex and heterogeneous activities of microorganisms. For the third volume of Soil Biology, an international board of renowned scientists shed light on the significant role of these organisms. The following key topics are covered: Microorganisms in bioerosion, humification, mineralization and soil aggregation; Microbial energetics and microbes in biogeochemical processes such as carbon and nitrogen cycles and phosphorus bio-availability; Interactions in the mycorrhizosphere, e.g. between mycorrhizal fungi and bacteria; Impact of microbes on plant nutrient cycling and the possible effects of transgenic rhizospheres on soil fungi; Functions of microbes in specific soil compartments such as soil surface or toxic metal polluted soils; Regulation of microbial activities in functional domains that are influenced by biotic or abiotic factors; Use of marker genes and isotopes as examples for modern techniques in soil microbiology.

Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.

In recent years, parasitologists have learned much about the way in which parasite biochemistry differs from that of free-living organisms. Inside the host, factors such as temperature, oxygen tension, carbon dioxide concentration and pH have important consequences for the biochemistry and physiology of the parasitic organism. Strong selection pressure therefore operates at all stages of a parasite's life cycle. The parasite's adaptational response to this pressure is the subject of this book. Under the headings "The nature of parasite adaptation", "Energy metabolism", "Digestion and uptake of nutrients", "Host immunity and parasite adaptation", "Biochemical adaptation and the magic bullet" and "Biochemical variation in parasites", present knowledge of parasite metabolism and how it reflects adaptation to particular environments is surveyed. The ways in which these adaptations may have developed during their evolution - with reference to the modern evolution of strain variations and the development of resistance to antiparasitic compounds - are explored, together with immunological aspects of the host-parasite relationship and potential metabolic targets for chemotherapy. This book should be of use to all those involved and interested in the biochemistry of parasites and its relation to their evolution, ecology, adaptation and variation. Those aspects of parasite metabolism that are attacked by anti-parasitic drugs are described, making this a useful book for those involved in the pharmaceutical industry. This book should be of interest to parasitologists and comparative biochemists.

This text offers a holistic approach to the two topics of the highest interest in the current and future food industry: sustainability and nutrition. The current knowledge is narrow and specific to individual topics focusing on either one nutrient or one discipline. Food is part of a wide circle of disciplines: nutrition, technology, sensory, environmental aspects, psychology, economy, culture and society. In the recent years, the sales of innovative foods such as meatless burgers, allergen-free products and personalized nutrition have skyrocketed. Sustainable Food Innovation presents the big picture on each nutrient: industrial and natural sources (ingredients, food products), consumer acceptability (price, sensory quality) and nutritional properties (quantity and quality) with each chapter focusing on a specific essential nutrient. Further chapters illustrate the role of other elements of interest such as bioactive. In addition, experimental data is added to enrich the book. Online discussions on current food trends are analyzed and presented to the reader in the effort to understand consumers' psychology. This will be the first publication to combine literature review and research data and the first to offer a comprehensive discussion on sustainable food innovation. The ultimate goal is to educate consumers and experts, providing technical and socioeconomic knowledge in a multidisciplinary context. Ultimately, informed technologists will develop healthier, sustainable food products and informed consumers will make informed decisions on nutrition and food choices.

Based on the proceedings of the Federation of European Microbiological Societies Symposium held at the Cranfield Institute of Technology, this book serves to highlight a wide variety of areas of civil engineering where microbiological activity needs to be considered more thoroughly by engineers during the design, construction and operation phases of projects. Examples of where microbial processes are now known to have a significant affect include corrosion, deterioration of concrete and other construction materials, impairment of flow in groundwater abstraction systems in pipes and pumps, pressure relief and drainage systems in embankment dams, clogging of irrigation and drainage systems, alteration of soil and rock properties and the production of harmful gases. For a long time many of these "buried" problems have been thought of, purely in terms of physical and chemical processes. What is often happening, but going unnoticed, is some form of microbial activity, which initiates, enhances or is encouraged by other processes. When it is considered that the average bacteria cell is only a few microns in size, then it is hardly surprising if their activity does often go unnoticed. At

Recent ideas and experimental studies suggest that the relationship between parasitism and host behaviour has been a powerful shaping force in the evolution not only of behaviour patterns themselves but, through them, of morphology and population and community dynamics. This book brings together recent work across the disciplines of parasitology and animal behaviour which is revealing the fundamental role of parasitism in the evolution of behaviour. The aim is to look broadly at the relationship between parasitism and behaviour from pathology and epidemiology to strategies of exploitation and counter exploitation. In doing so the book will traverse the phylogenetic scale from enteric protozoa and nematodes to colouration and courtship of birds and human cultural traditions.

This review of recent developments in our understanding of the role of microbes in sustainable agriculture and biotechnology covers a research area with enormous untapped potential. Chemical fertilizers, pesticides, herbicides and other agricultural inputs derived from fossil fuels have increased agricultural production, yet growing awareness and concern over their adverse effects on soil productivity and environmental quality cannot be ignored. The high cost of these products, the difficulties of meeting demand for them, and their harmful environmental legacy have encouraged scientists to develop alternative strategies to raise productivity, with microbes playing a central role in these efforts. One application is the use of soil microbes as bioinoculants for supplying nutrients and/or stimulating plant growth. Some rhizospheric microbes are known to synthesize plant growth-promoters, siderophores and antibiotics, as well as aiding phosphorous uptake.

The last 40 years have seen rapid strides made in our appreciation of the diversity of environmental microbes and their possible benefits to sustainable agriculture and production. The advent of powerful new methodologies in microbial genetics, molecular biology and biotechnology has only quickened the pace of developments. The vital part played by microbes in sustaining our planet's ecosystems only adds urgency to this enquiry. Culture-dependent microbes already contribute much to human life, yet the latent potential of vast numbers of uncultured-and thus untouched-microbes, is enormous. Culture-independent metagenomic approaches employed in a variety of natural habitats have alerted us to the sheer diversity of these microbes, and resulted in the characterization of novel genes and gene products. Several new antibiotics and biocatalysts have been discovered among environmental genomes and some products have already been commercialized. Meanwhile, dozens of industrial products currently formulated in large quantities from petrochemicals, such as ethanol, butanol, organic acids, and amino acids, are equally obtainable through microbial fermentation. Edited by a trio of recognized authorities on the subject, this survey of a fast-moving field-with so many benefits within reach-will be required reading for all those investigating ways to harness the power of microorganisms in making both agriculture and biotechnology more sustainable."

Since its discovery as the cause of infectious mononucleosis in 1964, the Epstein-Barr virus (EBV) has been etiologically implicated in an increasing number of human diseases. Generally considered the first human oncogenic virus because of a number of studies linking it with Burkitt's lymphoma and nasopharyngeal carcinoma (NPC), as well as its documented oncogenicity in nonhuman primates, EBVhas served as a model for identifying subsequent candidate oncogenic viruses and the stimulus for Evans' revision of the Henle-Koch postulates to accommodate the problems in proving viral oncogenicity in humans. Research on the role of EBV in human cancer was particularly en hanced (a) by the pioneering work of Werner and Gertrude Henle, and (b) by the coordinated efforts of the Special Virus Leukemia Program and its successors, the Special Virus Cancer Program and the Virus Cancer Program of the National Cancer Institute (NCI). Initiated by Dr. Frank J. Rauscher, who subsequently became director of the Ncr and is now Vice-President of the American Cancer Society, and expanded by Dr. John B. Moloney, whose contributions to cancer research were honored at this Second International Symposium on EBV and Associated Malignant Diseases, these NCI contract-sup ported programs brought together investigators from all over the world to participate in a joint effort to unravel the mystery of EBV behavior and pathogenicity. It was these programs that gave us the opportunity to work with such outstanding people as Professor Yohei Ito, to whom this book is dedicated."

This fifth volume in the series The Plant Viruses, dealing with viruses with bipartite genomes, completes the coverage of viruses with isometric parti cles and genomes consisting of single-stranded, positive-sense RNA: viruses that have tripartite and monopartite genomes of this kind were dealt with in Volumes 1 and 3, respectively. How close are the affinities among the viruses within the groupings distinguished in this way? All those with tripartite genomes are considered to be sufficiently closely related to be included in the family Bromoviridae, whereas the monopartite-genome viruses covered in Volume 3 clearly are a much more diverse collection. Affinities among the viruses with bipartite genomes are considered in Chapter 1 of this volume, along with the possible origins, advantages, and disadvantages of these ge nomes. The conclusion reached from this assessment is that the bipartite genome viruses fall into four categories, those within each category having closer affinities with viruses not included in this book than with viruses in the other categories. No evidence was found that possession of a bipartite genome gives a virus overwhelming advantages over viruses of other sorts. More probably, any advantages are largely balanced by disadvantages, and bipartite genomes may be best considered simply as an alternative design for the hereditary material of a virus."

An up-to-date view of molecular mechanisms for investigating microbial communities and their biological activities, this new volume of Environmental Microbiology: Methods and Protocols looks at recent advances that are having a big impact on the field such as metagenomics and other "omics" technologies, NanoSIMS, as well as stable isotope probing and more.

This book was written as part of the highly successful Methods in Molecular Biology series, and, as such, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Fully updated and authoritative, Environmental Microbiology: Methods and Protocols, Second Edition aims to provide an unprecedented glimpse into the structure, composition, and activity of microbial communities across diverse environments and illuminate their impact on global ecological processes.

This book is the third volume on Nanoscience in Food and Agriculture, published in the Sustainable Agriculture Reviews series. In this book we present ten chapters describing the synthesis and application of nanomaterials for health, food, agriculture and bioremediation.Nanomaterials with unique properties are now being used to improve food and agricultural production. Research on nanomaterials is indeed revealing new applications that were once thought to be imaginary. Specifically, applications lead to higher crop productivity with nanofertilisers, better packaging, longer food shelf life and better sensing of aromas and contaminants. These applications are needed in particular in poor countries where food is scarce and the water quality bad. Nanotechnology also addresses the age old issue of water polluted by industrial, urban and agricultural pollutants. For instance, research produces nanomaterials that clean water more efficiently than classical methods, thus yielding water for drinking and irrigation. However, some nano materials have been found to be toxic. Therefore, nanomaterials should be engineered to be safe for the environment.

This updated and expanded second edition reviews numerous aspects of the marine microbiome and its possible industrial applications. The marine microbiome is the total of microorganisms and viruses in the ocean and seas and in any connected environment, including the seafloor and marine animals and plants. In the first part of the book, diversity, origin and evolution of the marine microorganisms and viruses are discussed. The microbes presented originate from all three domains of life: Bacteria, Archaea, and Eukarya. The second part sheds some light on the different communities: it describes marine habitats and how their inhabitants control biogeochemical cycles. The third part finally examines the microbial ocean as a global system and evaluates methods of utilizing marine microbial resources. Adopting a translational approach, the book connects academic research with industrial applications, making it a fascinating read and valuable resource for microbiologists from both domains.

This book discusses the various aspects of sustainable packaging edibles in food industry. It is divided into five main parts. The first section of the book addresses details of edible films, various sources, origin, scope and functions. Second section covers different sustainable alternatives such as seed gums, fruits and vegetable peels, sea weeds, fruits wastes, dairy by products & anti-oxidant edible packaging. This book also discusses about methods of improvements of mechanical properties of packaging edibles & their food applications, testing methods, innovations, limitations, challenges and nano edibles. It provides insights about the large quantity of wastes and by-products generated by food processing industries. Disposal of these wastes is a big problem due to their high biochemical oxygen demand (BOD) & chemical oxygen demand (COD) which causes severe problem of pollution to the environment. These wastes contain large amounts of proteins, carbohydrates, lipids, minerals, various bioactive compounds and have eco-friendly packaging potential. The book emphasizes on the fact that recycling these wastes as packaging edibles are sustainable and economical. As a world foreseeing food technology revolution, this book explores the unique topics in food packaging which possesses mammoth commercial applications and environmental potential. Due to its immense scope, this book is highly useful for researchers, food scientists, students and food packaging industry experts.

This volume contains material first presented at an international workshop on the 'Use of Microorganisms to Combat Pollution', held in Israel, May 10--18, 1992. The workshop was sponsored by the Bat-Sheva de Rothschild Foundation for the Advancement of Science and included microbiologists, biochemists and geneticists from universities, environmental agencies and the military. Each of the contributors to this volume is an ack nowledged expert on the treatment of one or more types of pollution using microorganisms or their enzymes. This book differs from most published symposia proceedings in the breadth of coverage of each subject. Most of the chapters are divided into three parts: (a) A general presentation of the source and toxicity of the pollutant, (b) a review of the current state-of-the-science on the biodegradation of that pollutant and (c) the authors' unique research experiences on the problem. In several examples, the authors have presented data from both laboratory studies and field trials. Thus, the book contains not only the theoretical background on the biodegradation of pollutants, but also practical experiences in applying this knowledge to solving significant pollution problems."

Food-borne bacterial pathogens encounter a number of stressors during food processing and preservation. More and more pathogens are able to adapt their physiological properties and/or genetic expression to survive these stressors and pose a risk to food safety and public health. This book provides the reader with a comprehensive overview of common food processing-associated stressors (e.g., heat, cold, acid, osmosis, and oxidation) and deals with the molecular basis of the respective bacterial stress response mechanisms (e.g., viable but nonculturable state, biofilm formation, sporulation, and cross-protection response). Additionally, various chapters cover the response mechanisms of foodborne pathogens to emerging nonthermal sterilisation technologies such as ultrasound, high-pressure processing, pulsed electric fields, ultraviolet light, irradiation and phytochemicals. Through this book we also learn about future prospects for the efficient control of stress adaption in foodborne pathogens to ensure maximum consumer safety. This book offers a valuable resource for researchers, graduate students, food process engineers and product developers in the fields of food science and microbiology.

The 12th meeting on Frankia and Actinorhizal Plants that took place in Carry-le-Rouet, France in June 2001 was the opportunity for scientists to communicate about latest developments on this symbiosis that concerns a wide range of dicotyledonous plants, initiates ecological successions and is used in a number of countries to protect crops from winds or improve soil status. Selected papers on plant ecology, Frankia's genetics or physiology, and host plants' genetics or physiology are published in this special Plant & Soil issue.

This volume covers the most important parasitic protists that are known to infect humans. The pathogens discussed cause diseases like toxoplasmosis, malaria, cryptosporidiosis, leishmaniasis, amoebiasis, trichomoniasis, and giardiasis. Readers from microbiology will appreciate the special focus on protist cell biology. As demonstrated in several of the chapters, these parasites are characterized by peculiar structures and organelles that cannot be found in mammalian cells - even though both are eukaryotic. The book employs light and electron microscopy to display the changing morphology in various stages of parasitic development. In turn, the results are supplemented by transcriptome and proteome profiles that help to describe how these changes take place on a molecular level. Both researchers and clinicians from tropical medicine will find essential and practically applicable background information on these increasingly important pathogens.

'Developmental biology' is widely understood as processes, which mainly concern embryonic animal development and differentiation of cells and tissue. It is also often defined as the timeline for the evolutionary developmental biology of eukaryotic multicellular higher organisms, i.e., plants and animals. The development of prokaryotes and lower eukaryotes in contrary has been neglected for a long time, which was the motivation for publishing this book. This book highlights one of Darwin's most important findings: Evolution is a creative, but not a conscious process. It also illustrates that this concept does not only apply to multicellular higher organisms, but affects every form of life. The reader shall find complex biochemical and genetic pathways of bacteria, yeasts or protozoa, comparable to those exhibited by plants or animals. The molecular mechanisms of dramatic genome rearrangements, recombination and horizontal gene transfer that are responsible for evolutionary adaptations are discussed. Additionally, the book covers bacteria of the genera Myxobacteriales and Caulobacterales, which are able to develop tissue-like cellular organization. The morphogenesis of entomopathogenic fungi and the endosymbiont theory are also addressed. The book is a useful introduction to the field for junior scientists, interested in bacteriology, protistology and fungal development. It is also an interesting read for advanced scientists, giving them a broader view of the field beyond their area of specialization.
