This book describes the multitude of interactions between plant, soil, and micro-organisms. It emphasizes on how growth and development in plants, starting from seed germination, is heavily influenced by the soil type. It describes the interactions established by plants with soil and inhabitant microbial community. The chapters describe how plants selectively promote certain microorganisms in the rhizospheric ecozone to derive multifarious benefits such as nutrient acquisition and protection from diseases. The diversity of these rhizospheric microbes and their interactions with plants largely depend on plant genotype, soils attributes, and several abiotic and biotic factors. Most of the studies concerned with plant-microbe interaction are focused on temperate regions, even though the tropical ecosystems are more diverse and need more attention. Therefore, it is crucial to understand how soil type and climatic conditions influence the plant-soil-microbes interaction in the tropics. Considering the significance of the subject, the present volume is designed to cover the most relevant aspects of rhizospheric microbial interactions in tropical ecosystems. Chapters include aspects related to the diversity of rhizospheric microbes, as well as modern tools and techniques to assess the rhizospheric microbiomes and their functional roles. The book also covers applications of rhizospheric microbes and evaluation of prospects improving agricultural practice and productivity through the use of microbiome technologies. This book will be extremely interesting to microbiologists, plant biologists, and ecologists.

The new series "Microbiology Monographs" begins with two volumes on intracellular components in prokaryotes. In this first volume, "Inclusions in Prokaryotes", the components, labeled inclusions, are defined as discrete bodies resulting from synthesis of a metabolic product. Research on the biosynthesis and reutilization of the accumulated materials is still in progress, and interest in the inclusions is growing. This comprehensive volume provides historical background and comprehensive reviews of eight well-known prokaryotic inclusions.

Lactic acid bacteria (LAB) and bifidobacteria are among the most important groups of microorganisms used in the food industry. For example, LAB are used in the production of fermented products, such as yogurts, cheese, and pickled vegetables. In addition, LAB can inhibit the growth of spoilage microbes and/or pathogens in their environment by lowering the pH and/or through the production of antimicrobial peptides, called bacteriocins. Both LAB and bifidobacteria are also thought to have health-promoting abilities and many are used as probiotics for the prevention, alleviation, and treatment of intestinal disorders in humans and animals. In this comprehensive book, expert international authors review the most recent cutting-edge research in these areas. Topics include: lactobacillus genomics * bifidobacterium gene manipulation technologies * metabolism of human milk oligosaccharides in bifidobacteria * proton-motive metabolic cycles * oxidative stress and oxygen metabolism * bifidobacterium response to O2 * bile acid stress in LAB and bifidobacteria * protein structure quality control * bacteriocin classification and diversity * lactococcal bacteriocins * lactobacilli bacteriocins * other bacteriocins * production of optically pure lactic acid * antihypertensive metabolites from LAB * the anti-H. pylori effect of lactobacillus gasseri * probiotics for allergic rhinitis * probiotics health claims in Japan and Europe.

This book addresses multiple aspects of biological clocks in prokaryotes. The first part of the book deals with the circadian clock system in cyanobacteria, i.e. the pioneer of bacterial clocks. Starting with the history and background of cyanobacteria and circadian rhythms in microorganisms, the topics range from the molecular basis, structure and evolution of the circadian clock to modelling approaches, Kai systems in cyanobacteria and biotechnological applications. In the second part, emergent timekeeping properties of bacteria in microbiomes and bacteria other than cyanobacteria are discussed. Since the discovery of circadian rhythms in cyanobacteria in the late 1980s, the field has exploded with new information. The cyanobacterial model system for studying circadian rhythms (Synechococcus elongatus), has allowed a detailed genetic dissection of the bacterial clock due to state-of-the-art methods in molecular, structural, and evolutionary biology. Cutting-edge research spanning from cyanobacteria and circadian phenomena in other kinds of bacteria, to microbiomes has now given the field another major boost. This book is aimed at junior and senior researchers alike. Students or researchers new to the field of biological clocks in prokaryotes will get a comprehensive overview, while more experienced researchers will get an update on the latest developments.

Fungal growths affect both human and animal well-being. Many natural pathogens of laboratory animals alter host physiology, rendering the host unsuitable for experimental uses. While the number and prevalence of few pathogens have declined considerably, many still turn up in laboratory animals and represent unwanted variables in research. Investigators using laboratory animals in biomedical experimentation should be aware of the profound effects that many of these agents can have on research. What does the future hold regarding the natural pathogens of laboratory animals? The selection of an animal model must carefully address issues of the type of human disease to mimic, the parameters to follow, and the collection of the appropriate data to answer those questions being asked. Overall, animal models of fungal infection will continue to deepen our understanding of how these infections occur. This book provides a valuable source of information to biological and biomedical scientists and to clinical and doctoral researchers working in the area of fungal infections and diseases of laboratory animal species.

Salmonellae are important pathogens, responsible for an estimated one million deaths and 100 million human infections annually. Their genomes are mosaic puzzles, results of lateral transfer events that occur within a stable genetic background. Extraordinary diversity of host ranges and pathogenicity traits between different strains are the consequence of both specific genome insertions/deletions and minute changes in genome composition. Genomic information decoded from a multitude of different Salmonella strains and new dramatic insights into pathogenic processes emphasize the fact that Salmonella research is currently at a very exciting juncture. In addition to their fascinating resilience in both the environment and eukaryotic hosts, Salmonella prefer tumors over any other location within the human host (by a factor of 1000 or more). This ability could propel Salmonella into future use as a therapeutic delivery agent to control and/or cure cancers. In this book, internationally accla

Bacteria have evolved with extraordinary abilities to regulate aspects of their behavior (such as gene expression) in response to signals in the intracellular and extracellular environment. Key to this are the diverse macromolecules (proteins or RNA) that sense change through direct interactions with chemical or physical stimuli. In recent years, there have been tremendous advances in understanding the structure and function of these signal receptors, and how interaction with the signal triggers changes in their activity and downstream events. For some systems, this understanding extends to the atomic level. In this unique book, an international team of experts reviews a selection of important model systems, providing a timely snapshot of the current state of research in the field. Sensory Mechanisms in Bacteria opens with an introductory chapter that reviews the diversity of signal recognition mechanisms, illustrating the breadth of the field.
