Pseudomonas Syringae Pathovars And Related Pathogens Identification Epidemiology And Genomics

This book reports on recent advances on: (1) new methods and approaches for specific and sensitive detection and identification of Pseudomonas syringae and Ralstonia solanacearum; (2) ecology and epidemiology bases of Pseudomonas syringae that enable the development of management strategies; (3) pathogenesis and determinant of pathogenicity, and in particular, mechanisms involved in virulence and virulence gene expression; (4) evolution and diversity of the pseudomonads through multilocus sequence typing (MLST) analysis; (5) determination of pathogens associated with new and emerging diseases; (6) effect of global warming on increase and emergence of new bacterial diseases."

During the last decade, research on Pseudomonas syringae pathovars and related pathogens has progressed rapidly, opening up many new avenues. The application of molecular genetics has provided new insights into determinants of pathogenicity and virulence. Progress has also been made in elucidating the chemical structures and modes of action of phytotoxins from Pseudomonas syringae; by establishing novel strategies for disease control; in biotechnological applications; by studying the resistant reaction of the plant with a combined biochemical and genetic approach; and in the development of new detection and identification methodologies as tools in epidemiological studies. With such rapid advances it becomes more and more difficult to keep abreast of the developments and concepts within disciplines, all involving research on pathovars of P. syringae. In an attempt to provide a balanced overview, recent developments in these rapidly expanding fields have been critically reviewed at the beginning of each chapter by internationally renowned experts. Our comprehensive coverage has been made possible because all the contributors to this volume presented their latest findings at the `5th International Conference on Pseudomonas syringae Pathovars and Related Pathogens' in Berlin, September 3-8, 1995. In this way, it was possible to bring together contributions from a wide range of fields including phytopathology, genetics, bacteriology, plant breeding, plant protection, and taxonomy. This book is not intended simply as a record of the proceedings of the Berlin Conference, but as an extension of recent findings and hypotheses put forward at the meeting. All papers published in this volume have been reviewed by the Editors.

Population genomics is a rapidly emerging field that has the potential to transform our understanding of how evolutionary forces shape genomic diversity among microbes. There have already been considerable advances in understanding gene flow and spread of adaptive traits, and in linking epidemiology with evolutionary biology. The current challenge is to find unifying evolutionary principles for organisms that display a wide range of reproductive biology – from highly clonal to promiscuous – and for which the vast majority have eluded cultivation. This requires interdisciplinary approaches that incorporate novel computational tools, testing of existing and novel population genetic models, and creative new ways of linking genetic diversity to ecological factors. This pioneering book will discuss the advances made and promises of population genomics in microorganisms, outlining some of the key theoretical and practical challenges for microbial population genomics, including defining and identifying populations, genomics-based reverse ecology and building appropriate tools to understand microbes in a variety of complex environments.

This second volume of a two-volume work reviews beneficial bioactive compounds from various microorganisms such as bacteria, fungi, cyanobacteria in plant diseases management and the postharvest management of fruits using microbial antagonists. Furthermore, it reviews the impact of climate change on food security and addressed the legal aspects of microbial biocontrol applications. The two-volume work “Microbial Biocontrol” introduces to mechanisms of plant-microbe interactions and explores latest strategies of how microbes can be applied in biocontrol and management of plant pathogens, replacing chemical fertilizers and pesticides. The book covers different groups of microorganisms such as bacteria, fungi, but also the interplay of entire microbiomes, and reviews their specific benefits in crop growth promotion, in enhancing the plants’ tolerance against biotic and abiotic stress as well as in post-harvest management of various plant diseases. Novel tools such as CRISPR/Cas9 and microbe derived nanoparticles are also addressed besides the legal aspects of biocontrol applications. Today, rising global population and changing climatic conditions emerge as a major challenge for agronomist farmers and researchers in fulfilling the requirements of global food production. The conventional agricultural practices utilize undistributed use of chemical fertilizers and pesticides to enhance growth and yield of agricultural products and fresh foods, but their extensive and continuous use have led to a range of negative consequences on the food quality and safety, to environment as well as to human and animal health. Microbial biocontrol applications are presented as a solution, paving the way to a sustainable agriculture in compliance with the UN Sustainable Development Goals (SDG). The book addresses researchers in academia and agriculture.

Plant pathogens cause significant economic losses and endanger agricultural sustainability. The emergence of new plant diseases is caused primarily by international trade, climate change, and pathogens' ability to evolve quickly. Rapid and accurate identification of plant pathogens is critical for disease management. The diversity and distribution of plant pathogens, on the other hand, can significantly impede disease management and diagnostic efforts. Plant pathogens employ a number of strategies that result in diversity, transmission, and host adaptation. Plant pathogens have been observed interacting with a wide range of host species such as plants, endophytes, insects, pollinators, and other plant pathogens. However, the transmission and evolution of plant pathogens in hosts, as well as the impact of pathogens on different hosts, are often unknown.

Plants create a dynamic micro-biosphere in the soil, around the roots, called as ‘rhizosphere’, which harbors diverse number of microorganisms for sustaining their growth and development. A soil with diverse and multi-traits microbial communities is considered healthy to enhance crop productivity. In the last decades, rhizosphere biology has gained attention due to unraveling of new mechanisms, processes and molecules in the rhizosphere that contributes towards the promotion of plant productivity. The rhizospheric microbes and associated processes are being utilized for harnessing potential of soils in effective and sustainable functioning in the agro-ecosystems. Broadly, the book discusses rhizospheric microbes and their role in modulating functions of soil and crop plant. Specifically, it highlights conventional and modern aspects of rhizosphere microbes such as – microbiome in the rhizosphere, microbes as an indicator and promoter of soil health, rhizosphere microbes as biofertilizer, biostimulator and biofortifyer, microbial signaling in the rhizosphere, recent tools in deciphering rhizobiome, and regulatory mechanisms for commercialization of biofertilizer, biopesticide and biostimulator. The book is useful for agriculture scientist, biotechnologist, plant pathologist, mycologist, and microbiologist, farming community, scientist of R&D organization, as well as teaching community, researcher and student and policy maker.
