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.

Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today’s world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. ‘Plant Microbe Symbiosis – Fundamentals and Advances’ provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields. The book reviews the enormous diversity of plant associated microbes, the dialog between plant-microbes-microbes and mechanisms of action of PGP microbes. Utilization of PGPRs as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bioformulations.
Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. It is a discipline that addresses current issues: climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. This series gathers review articles that analyze current agricultural issues and knowledge, then proposes alternative solutions.
This books presents an updated compilation on fundamental interaction mechanisms of microbial communities with the plant roots and rhizosphere (belowground) and leaves and aerial parts (aboveground). Plant rhizopshere recruits its own microbial composition that survive there and help plants grow and develop better under biotic and abiotic conditions. Similar is the case with the beneficial microorganisms which are applied as inoculants with characteristic functions. The mechanism of plant-microbe interactions is interesting phenomenon in biological perspectives with numerous implications in the fields. The First volume focuses on the basic and fundamental mechanisms that have been worked out by the scientific communities taking into account different plant-microbe systems. This includes methods that decipher mechanisms at cellular, physiological, biochemical and molecular levels and the functions that are the final outcome of any beneficial or non-beneficial interactions in crop plants and microbes. Recent advances in this research area is covered in different book chapters that reflect the impact of microbial interactions on soil and plant health, dynamics of rhizosphere microbial communities, interaction mechanisms of microbes with multiple functional attributes, microbiome of contrasting crop production systems (organic vs conventional), mechanisms behind symbiotic and pathogenic interactions, endophytic (bacterial and fungal) interaction and benefits, rhizoplane and endosphere associations, signalling cascades and determinants in rhizosphere, quorum sensing in bacteria and impact on interaction, mycorrhizal interaction mechanisms, induced disease resistance and plant immunization, interaction mechanisms that suppress disease and belowground microbial crosstalk with plant rhizosphere. Methods based on multiphasic and multi-omics approaches were discussed in detail by the authors. Content-wise, the book offers an advanced account on various aspects of plant-microbe interactions and valuable implications in agro-ecological perspectives.
The existence of living organisms in diverse ecosystems has been the focus of interest to human beings, primarily to obtain insights into the diversity and dynamics of the communities. This book discusses how the advent of novel molecular biology techniques, the latest being the next-generation sequencing technologies, helps to elucidate the identity of novel organisms, including those that are rare. The book highlights the fact that oceans, marine environments, rivers, mountains and the gut are ecosystems with great potential for obtaining bioactive molecules, which can be used in areas such as agriculture, food, medicine, water supplies and bioremediation. It then describes the latest research in metagenomics, a field that allows elucidation of the maximum biodiversity within an ecosystem, without the need to actually grow and culture the organisms. Further, it describes how human-associated microbes are directly responsible for our health and overall wellbeing.“/p>

Increased interest in the basic biology of plants and microorganisms stems from the fact that crop productivity is directly affected by plant-microbe interactions. In spite of the fact that plants exist in the environment amongst diverse species of microorganisms, only a few ever establish a direct relationship. Emerging awareness concerning the indirect effect of microbial association on plant growth and the possibility of using one microbe against another for controlling pathogenic interactions is at the genesis of new fields of studies. The primary reason for a microbe to associate with· photoautotrophic organisms (plants) is to tap its nutritional requirements, fixed carbon, as a source of energy. By hook or by crook, a microbe must survive. Some have evolved mechanisms to exploit plants to develop a niche for their biotropic demands. When in contact with a living plant, microorganisms may live in a passive association using exudates from the plant, invade it pathogenically or coexist with it in symbiosis. The plant responds to the interloper, either reacting in a hypersensitive manner to contain the invasion of pathogens, or by inducing a set of genes that leads toward symbiosis, or by simply succumbing to the invader. Thus, prior to contact wi th the plant, mic roorganism is able to sense the presence of the host and activate accordingly a set of genes required for the forthcoming interaction, whether symbiotic or pathogenic.
The book addresses current public concern about the adverse effect of agrochemicals and their effect on the agro-ecosystem. This book also aims to satisfy and contribute to the increasing interest in understanding the co-operative activities among microbial populations and their interaction with plants. It contains chapters on a variety of interrelated aspects of plant-microbe interactions with a single theme of stress management and sustainable agriculture. The book will be very useful for students, academicians, researcher working on plant-microbe interaction and also for policy makers involved in food security and sustainable agriculture.
The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.

Microbiology has undergone a number of metamorphoses in its relatively brief existence. It has been in approximate succession, morphology, epidemiology, biochemistry, genetics, and molecular biology. It is also becoming a significant parcel of cell surface studies. The one embodiment which has remained elusiv- particularly for bacteriology - is the taxonomic one. This may have been a blessing in disguise because it encouraged microbiologists to deal with the general rather than the particular; promoting a search for unitary explanations, in the manner of Kluyver and van Niel, long before anyone knew about the universality of the genetic code, or could trace the genealogy of enzymes from the study of amino acid substitutions. . This volume is predicated on the idea that deep analogies underly the mech anisms of cellular interaction, and therefore belongs in the unitary tradition of microbiology. It occupies itself with a wide variety of micro-organisms, considering them from vantage points of considerable diversity, ranging from taxonomic irreverence to keen evolutionary awareness, and is concerned with areas which have developed independently of each other.

The fact that infectious diseases claim over 17 million victims worldwide each year, along with the regular emergence of new drug resistance pathogens, signals that infectious diseases will continue to be a daily concern of the Physician well into the future. This reality requires that today's medical students develop a solid foundation in medical microbiology -- a foundation they can achieved by using IMS: Microbial Pathogenesis. This book is developed in response to the changing field of medical microbiology. The number of diseases and the diversity of microbial pathogens that cause these diseases are far too many for simple taxonomic organization. As a result, IMS Microbial Pathogenesis focuses on the common principles of infection rather than the old taxonomic organization, enabling a better long term retention of relevant material, and minimizing the short-term memorization of specific "factoids," many of which may become out-dated in a short time.
This volume provides insights into current research on fungal populations, communities and their interactions with other organisms. It focuses on fungal responses to the physical environment; interactions with bacteria, other fungi, invertebrates and plants; the role of fungi in ecosystem processes such as decomposition and nutrient cycling; and aspects of biogeography and conservation. Since the publication of the second edition of Volume IV in 2007, the massive use of “omics” methods has revolutionized our understanding of fungal lifestyles. Highlighting these advances, the third edition has been completely updated and revised. Several chapters deal with various applications of genomics and transcriptomics in biological pest control, as well as interactions with other living systems. This is an invaluable source of information both for scientists who wish to update their knowledge of current advances and for graduate students interested in obtaining a comprehensive introduction to this field of research.

This monograph provides an overview of beneficial plant-bacterial interactions in a straightforward and easy-to-understand format, and includes a wealth of unique illustrations elaborating every major point. Study questions that emphasize the key points are provided at the end of each chapter. One way to feed all of the people in the world’s growing population is through the increased use of plant-growth-promoting bacteria in agriculture. These bacteria not only directly promote growth but also protect plants against a wide range of biotic and abiotic stresses. Moreover, they can be used to support procedures for biologically cleaning up the environment. Plant-growth-promoting bacteria are already being used successfully on a small scale in several countries, and as this technology matures, the world may witness a major paradigm shift in agricultural practice.
