The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance.

""Bacteria in Agrobiology: Stress Management"" covers the major aspects on PGPR in amelioration of both abiotic and biotic stresses. PGPR mediated in priming of plant defense reactions, nutrient availability and management in saline and cold environment, hormonal signaling, ACC deaminase and its role in ethylene regulation under harsh conditions are suitably described.

Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

Retroviruses have been of great importance to biomedical science for the past half century. Initially, studies on oncogenic animal retroviruses provided important insights into molecular processes in carcinogenesis – most notably the existence and mechanisms of action of oncogenes and proto-oncogenes. Moreover, several human diseases are caused by retroviruses, including AIDS, adult T-cell leukemia and the neurological disease HAM/TSP. The topic of this volume is a relatively unknown animal retrovirus, jaagsiekte sheep retrovirus, the causative agent of transmissible lung cancer in sheep –ovine pulmonary adenocarcinoma. The disease was first documented in South Africa in the 1800s, it has a wide geographical distribution, and it is of economic importance in high endemic regions. However, until very recently the nature of the etiologic agent was unclear, and relatively few laboratories actively studied the disease.

Beginning with the basics of lactic acid bacteria and stress response, then working into specific fields of research and current developments, "Stress Responses of Lactic Acid Bacteria" will serve as an essential guidebook to researchers in the field, industry professionals, and advanced students in the area.

The exploration of stress responses in lactic acid bacteria began in the early 90s and revealed the differences that exist between LAB and the classical model microorganisms. A considerable amount of work has been performed on the main genera / species of LAB regarding the genes implicated and their actual role and regulation, and the mechanisms of stress resistance have also been elucidated. Recent genome and transcriptome analyses complement the proteome and genetic information available today and shed a new light on the perception of and the responses to stress by lactic acid bacteria.

This unique book explores the role of retrotransposons in human health and disease. The ability of retrotransposons to affect the structure of human genes is recognized since the late 80's. However, the advances of deep-sequencing technologies have shed new light on the extent of retrotransposon-mediated genome variations. These progresses have also led to the discovery that retrotransposon activity is not restricted to the germline - resulting in inheritable genetic variations - but can also mobilize in somatic tissues, such as embryonic stem cells, neuronal progenitor cells, or in many cancers. This book covers topics related to the effects of retrotransposon insertions, and their consequences on germline and somatic genome dynamics, but also discuss the role and impact of retrotransposons sequences in a broader context, including a number of novel topics that emerged recently (long non-coding RNA, neuronal disorders, exaptation) with unexpected connections between retrotransposons, stem cell maintenance, placentation, circadian cycles or aging.

In Antoni van Leeuwenhoek, Master of the Minuscule, the Father of Microbiology is presented in the context of his time, relationships and the Dutch Golden Age.

Over the last decades, scientists have been intrigued by the fascinating organisms that inhabit extreme environments. These organisms, known as extremophiles, thrive in habitats which for other terrestrial life-forms are intolerably hostile or even lethal. Based on such technological advances, the study of extremophiles has provided, over the last few years, ground-breaking discoveries that challenge the paradigms of modern biology. In the new bioeconomy, fungi in general, play a very important role in addressing major global challenges, being instrumental for improved resource efficiency, making renewable substitutes for products from fossil resources, upgrading waste streams to valuable food and feed ingredients, counteracting life-style diseases and antibiotic resistance through strengthening the gut biota, making crop plants more robust to survive climate change conditions, and functioning as host organisms for production of new biological drugs. This range of new uses of fungi all stand on the shoulders of the efforts of mycologists over generations. The book is organized in five parts: (I) Biodiversity, Ecology, Genetics and Physiology of Extremophilic Fungi, (II) Biosynthesis of Novel Biomolecules and Extremozymes (III) Bioenergy and Biofuel synthesis, and (IV) Wastewater and biosolids treatment, and (V) Bioremediation.

Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields - the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice-wheat cropping system has now either got reduced or in some places has become constant for the last decade.

Molecular Mechanisms of Plant and Microbe Coexistence presents studies on the complex and manifold interactions of plants and microbes at the population, genomics and proteomics level. The role of soil microbial diversity in enhancing plant health and plant microbe beneficial symbioses is discussed. Microbial communities are shown in the light of evolution. Main topics include genome coexistence and the functional genomics and proteomics of plant-associated microbes, which could form the basis for new environmentally benign strategies to combat infectious plant diseases and regulate plant growth. Further chapters focus on the role of signaling during the different stages of plant microbe coexistence, in symbiotic or pathogenic relationships, in quorum sensing and plant viral infections. Methods for studying the interactions in the root zone complement the book, which will certainly be of relevance in the practical application to agriculture, food security and for maintaining the balance of our ecosystems. Written for: Researchers in microbiology, plant sciences, plant breeding, agriculture and soil ecology

Bacteria pathogenic for plants are responsible for devastating losses in agriculture. The use of antibiotics to control such infections is restricted in many countries due to worries over the evolution and transmission of antibiotic resistance. The advent of genome sequencing has enabled a better understanding, at the molecular level, of the strategies and mechanisms of pathogenesis, evolution of resistance to plant defense mechanisms, and the conversion of non-pathogenic into pathogenic bacteria. In this book, internationally acclaimed experts review the most important developments, providing an invaluable up-to-date summary of the molecular biology and genomics of plant pathogenic bacteria. The book opens with two chapters on bacterial evolution, diversity, and taxonomy - topics that have been transformed by molecular biology and genomics analyses. The third chapter delves into the crucially understudied area of pathogen adaptation to the plant apoplast environment. The next seven chapters focus on specific plant pathogens: Agrobacterium, Leifsonia, Pectobacterium, Pseudomonas, Ralstonia, Xanthomonas, and Xylella. The following four chapters review specific, intensively studied areas of research in the plant pathogen field: microbe associated molecular patterns (MAMPs) and innate immunity; use of bacterial virulence factors to suppress plant defense; cyclic di-GMP signalling and the regulation of virulence; and plasmids and the spread of virulence. The final chapter covers the critical area of bioinformatics. With contributions from some of the pioneering bacterial plant pathogen genome sequencers, this book is essential reading for every plant pathogen researcher - from the PhD student to the experienced scientist - as it provides a timely review of the current and most topical areas of research.

'A brilliant book [that] shows a way out of the destructive trap of Anthropocentric arrogance.' Vandana Shiva, from the Foreword Biocivilisations is a fascinating, original and important exploration into how complex civilisations existed on Earth long before humans. What is life? This is arguably the most important question in all of science. Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Everything can be sequenced and explained. But in a world as rich and complex as this one, can such an assertion really be true? A growing army of scientists, philosophers and artists do not share this mechanistic vision for the science of life. The gene metaphor is not only too simplistic but also misleading. If there is a way to reduce life to a single principle, how does that principle acknowledge the creativity of life that turns both genetic and information determinism on their heads? Biocivilisations is a groundbreaking book exploring the mysteries of life and its deep uncertainty. Dr Predrag Slijep�ević turns anthropocentric scientific thinking on its head, showing how the humble bacteria created the equivalent of cities and connected them with information highways, bringing our planet to life three thousand million years ago. He explains how bacteria, amoebas, plants, insects, birds, whales, elephants and countless other species not only preceded human beings but also demonstrate elements of complex civilisation – communication, agriculture, science, art, medicine and more – that we associate with human achievement. More than 99.99 percent of life on Earth has existed without humanity, and life will continue without humans long into the future. Biocivilisations is an important rethinking of the current scientific paradigm. It challenges us to reconsider the limited scope and time-window of our current ‘scientific revolution’ and to fundamentally reimagine what we call ‘life on Earth’.
