Book Description
This book describes how genomics has revolutionized our scientific understanding of agriculturally important plant-associated bacteria. Each chapter focuses on the genomics of particular bacteria: the first described plant pathogen, Erwinia amylovora; phytoplasmas lacking cell walls; fastidious, phloem-restricted liberibacters; Pseudomonas syringae, which is a genetically tractable model system; Xanthomonas citri, which causes a disease that can devastate citrus crops and Pseudomonas fluorescens, which can protect plants from diseases. Topics considered in this volume include the importance of horizontal gene transfer in originating new bacterial strains and species and advances in transcriptomics that allow us to describe the complex regulatory networks critical to plant-microbe interactions. The availability of the Xanthomonas oryzae genome has led to new technologies in genome editing, which will revolutionize approaches to genetic engineering, even in eukaryotes. The contributions show how genomics has greatly accelerated progress toward understanding the biology of these bacteria and how that understanding can be translated into novel crop protection methods.

Book Description
This volume is envisioned as a resource for researchers working with beneficial and harmful groups of bacteria associated with crop plants. The book is divided into two parts, with Part I on beneficial bacteria including chapters on symbiotic nitrogen fixers and rhizosphere bacteria. The second part consists of detailed descriptions of 8 genera of plant pathogenic bacteria, including Agrobacterium and Herbaspirillum. Each chapter covers terminology, molecular phylogeny and more. soft-rot, Pseudomonas, Xanthomonas, Ralstonia, Burkholderia and Acidovorax There is an opening chapter on the plant-associated bacteria survey, molecular phylogeny, genomics and recent advances. And each chapter includes terminology/definitions, molecular phylogeny, methods that can be used (both traditional and latest molecular tools) and applications

Book Description
Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria brings together the expertise of a panel of researchers from around the world to provide comprehensive up-to-date reviews on the most interesting aspects of genomic and phenotypic plasticity in plant-beneficial and phytopathogenic bacteria. The book covers various topics, including common and specific features in the genomes of symbiotic, plant-growth-promoting, and phytopathogenic bacteria; regulation of conjugative plasmid transfer in rhizobia; genetic and phenotypic variability in plant-beneficial pseudomonads and azospirilla; genomic fluxes in phytopathogenic xanthomonads and pseudomonads; genome plasticity in obligate parasitic Phytoplasmas; comparative genomics of plant-growth-promoting and phytopathogenic Herbaspirillum species; horizontal gene transfer in planta and microevolution of plant-associated bacteria in the phytosphere. Plasticity in Plant-Growth-Promoting and Phytopathogenic Bacteria is recommended for all microbiology and plant biology laboratories.

Book Description
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.

Book Description
Both bacteria increased lateral root numbers on Arabidopsis plants and genome annotation indicated each posses the auxin synthesis gene, ipdC. As auxin is known to play a role in lateral root development, subsequent work on lateral root promotion focused on this phytohormone. As part of this work, a plasmid was constructed that expressed the ipdC gene and could be stably maintained without selection pressure. While these enteric endophytes are related to human pathogens and Kp342 was found to have pathogenic potential, the information gained by studying these bacteria could yield insight into enhancing the growth-promoting effects of other endophytes. Thus, the work described here exemplifies how metagenomic, genomic, and biological experiments can be used to gain both an overview and in depth view of plant-bacterial associations.

Book Description
Although we can't usually see them, microbes are essential for every part of human life-indeed all life on Earth. The emerging field of metagenomics offers a new way of exploring the microbial world that will transform modern microbiology and lead to practical applications in medicine, agriculture, alternative energy, environmental remediation, and many others areas. Metagenomics allows researchers to look at the genomes of all of the microbes in an environment at once, providing a "meta" view of the whole microbial community and the complex interactions within it. It's a quantum leap beyond traditional research techniques that rely on studying-one at a time-the few microbes that can be grown in the laboratory. At the request of the National Science Foundation, five Institutes of the National Institutes of Health, and the Department of Energy, the National Research Council organized a committee to address the current state of metagenomics and identify obstacles current researchers are facing in order to determine how to best support the field and encourage its success. The New Science of Metagenomics recommends the establishment of a "Global Metagenomics Initiative" comprising a small number of large-scale metagenomics projects as well as many medium- and small-scale projects to advance the technology and develop the standard practices needed to advance the field. The report also addresses database needs, methodological challenges, and the importance of interdisciplinary collaboration in supporting this new field.

Book Description
Molecular Aspects of Plant Beneficial Microbes in Agriculture explores their diverse interactions, including the pathogenic and symbiotic relationship which leads to either a decrease or increase in crop productivity. Focusing on these environmentally-friendly approaches, the book explores their potential in changing climatic conditions. It presents the exploration and regulation of beneficial microbes in offering sustainable and alternative solutions to the use of chemicals in agriculture. The beneficial microbes presented here are capable of contributing to nutrient balance, growth regulators, suppressing pathogens, orchestrating immune response and improving crop performance. The book also offers insights into the advancements in DNA technology and bioinformatic approaches which have provided in-depth knowledge about the molecular arsenal involved in mineral uptake, nitrogen fixation, growth promotion and biocontrol attributes.

Book Description
The Rhizobiaceae, Molecular Biology of Model Plant-Associated Bacteria. This book gives a comprehensive overview on our present molecular biological knowledge about the Rhizobiaceae, which currently can be called the best-studied family of soil bacteria. For many centuries they have attracted the attention of scientists because of their capacity to associate with plants and as a consequence also to specifically modify plant development. Some of these associations are beneficial for the plant, as is the case for the Rhizobiaceae subgroups collectively called rhizobia, which are able to fix nitrogen in a symbiosis with the plant hosts. This symbiosis results in the fonnation of root or stem nodules, as illustrated on the front cover. In contrast, several Rhizobiaceae subgroups can negatively affect plant development and evoke plant diseases. Examples are Agrobacterium tumefaciens andA. rhizogenes which induce the formation of crown galls or hairy roots on the stems of their host plants, respectively (bottom panels on front cover). In addition to the obvious importance of studies on the Rhizobiaceae for agronomy, this research field has resulted in the discovery of many fundamental scientific principles of general interest, which are highlighted in this book. To mention three examples: (i) the discovery of DNA transfer of A.
