This book was released on 2011 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pathogenicity of plant pathogen Pseudomonas syringae depends on the type III secretion system which translocates effector proteins into host cells. In response, plants have evolved resistance proteins to detect presence of specific effectors and activate defense responses. The constant host surveillance imposes a strong selective pressure on effector proteins to evolve rapidly in order to evade detection. The P. syringae HopZ1 effector has evolved into three allelic forms as a result of diversifying selection. In this thesis, I aimed to investigate how sequence divergence contributes to the distinct allelic specificities of HopZ1. Mutational analysis of HopZ1a identified three amino acid residues that were potentially involved in dampening host defense responses, and two HopZ1a mutants partially lost the ability to trigger defense responses yet did not lose their virulence functions. These results suggested that distinct host targets could be involved in the defense-eliciting activity and virulence function of HopZ1a.

Download or read book Physiological Plant Pathology written by R. Heitefuß and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants. Physiological plant pathology represents those specialities within plant pathology which focus on the physiological and biochemical activities of pathogens and on the response of host plant tissues. Today there is an increasing recognition on the part of the scientific agri cultural community that only through a deeper and more fundamental under standing of all the interacting components of the agricultural biota can we expect to improve our capabilities of feeding an expanding world population. It is in this context that physiological plant pathology has assumed new significance within the broader field of plant pathology. No longer are studies on the biochemistry and physiology of pathogens and pathogenesis merely isolated academic exercises; rather, a substantial coherent body of knowledge is accumulating upon which our understanding of the process of disease developmen t and host resistance is being founded. It is from these foundations of knowledge that ultimately new insights into the control of plant diseases may be expected to grow. It seems appropriate, therefore, that at regular intervals those involved in the various subspecialities encompassing the broadest aspects of physiological plant pathology reassess the contributions within the particular specialities in the light of new knowledge and technologies for the purpose of articulating new and productive directions for the future.
Download or read book Genomics of Plant Associated Bacteria written by Dennis C. Gross and published by Springer. This book was released on 2014-06-16 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Natural and Engineered Resistance to Plant Viruses written by Michael Buchmeier and published by Academic Press. This book was released on 2010 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viral hemorrhagic fevers (VHFs) are a group of illnesses that are caused by several distinct families of viruses. While some types of hemorrhagic fever viruses can cause relatively mild illnesses, many of these viruses cause severe life-threatening disease. Some examples include: Lassa fever, Marburg virus, Ebola virus, Bolivian hemorrhagic fever, Korean hemorrhagic fever, Crimean-Congo hemorrhagic fever and Dengue hemorrhagic fever. No current treatment can cure viral hemorrhagic fevers, and immunizations exist for only two (yellow fever and Argentine hemorrhagic fever) of the many VHFs. Researchers are working to develop other vaccines, but in the meantime, the best approach is prevention. This volume will provide a review of what is known to date on these virus families as well as highlighting recent advances and future needs. Key features: * Provides comprehensive overview of what is known to date, recent advances and future needs * Examines transmission and risk factors * Highlights what has been done to help in outbreak control * Discusses the need for vaccines and antivirals
Download or read book Plant Virology written by R. E. F. Matthews and published by Academic Press. This book was released on 2013-10-22 with total page 916 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Virology, Second Edition, was written to cover the substantial developments in many areas of plant virology since the first edition was published. Advances have been made in all branches of the subject, but these have been most far reaching with respect to the structure of viruses and of their components, and in the understanding of how viral genomes are organized and how viruses replicate in cells. Significant developments have also occurred in the understanding of how viruses are transmitted by invertebrates and in the application of control measures for specific diseases. The taxonomy of viruses has advanced significantly, and there are now 25 internationally approved families and groups of plant viruses. All these developments have required that most sections be entirely rewritten. This book is intended primarily for graduate students in plant pathology, plant virology, general virology, and microbiology, and for teachers and research workers in these fields. It should also prove useful to some people in related disciplines—molecular biologists, biochemists, plant physiologists, and entomologists.
