Download or read book Leafhopper Vectors and Plant Disease Agents written by Karl Maramorosch and published by Elsevier. This book was released on 2012-12-02 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leafhopper Vectors and Plant Disease Agents is the second in a multivolume series on vectors, vector-borne disease agents, and plant disease spread. This text aims to collect findings in leafhopper vector research, to suggest promising frontiers for further research, and to call attention to possible practical applications of understanding of leafhopper-pathogen-plant interactions. This book is organized into five parts. Opening chapters on the taxonomy, bionomics, and worldwide importance of leafhopper and planthopper vectors are appropriately relegated to Parts I and II. Part III focuses on vector-virus interactions of leafhopper-, planthopper-, and aphid-borne viruses and virus-induced, cytopathological changes in vectors. This part also explains the interactions of mycoplasmalike organisms (MLOs) and viruses in dually infected leafhoppers, planthoppers, and plants, as well as the transitory vector-virus interactions. The artificial and aseptic rearing of vectors, microinjection technique, vector tissue culture, and spiroplasmas and its vectors are all covered in Part IV. Part V contains chapters on specific leafhopper-borne viruses and MLOs, leafhopper and planthopper vector control, leafhopper-borne pathogens of corn-stunting diseases, Western X disease, and leafhopper-borne xylem-restricted pathogens. This text will be valuable for students, teachers, and researchers of vector-pathogen-plant relationships. Its in-depth coverage of leafhoppers and planthoppers as vectors makes this book ideally suited as a supplemental text in graduate entomology and plant pathology courses on insect transmission of plant disease agents.

Download or read book Aphids as Virus Vectors written by Kerry F. Harris and published by Elsevier. This book was released on 2014-05-10 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids as Virus Vectors focuses on aphids as vectors of plant viruses and the fundamentals of their relationship with virus and host. The mouthparts and feeding mechanism of aphids are discussed, along with aphid penetration of plant tissues and the transmission mechanisms of aphids as virus vectors. The intrinsic properties and taxonomy of aphid-borne viruses are also examined. Comprised of 22 chapters, this book begins with an overview of the importance of aphids as vectors, their biology, and the properties of the viruses they transmit. These introductory chapters prepare the reader for later ones on aphid-virus-plant interactions. The next section deals with transmission mechanisms, with emphasis on several novel alternatives to many of the traditionally held concepts of how aphids transmit viruses. Accessory factors in non-persistent virus transmission are considered. Subsequent chapters focus on technological advances in aphid-virus research, including the use of aphid cell culturing, radioisotope methodology, membrane feeding, and electrical measurement systems. The most promising frontiers in epidemiological and control-oriented research are discussed in the last two sections. This monograph will be a useful resource for researchers from such varied sciences as entomology, plant science, and virology, as well as for graduate students taking entomology and plant pathology courses on insects in relation to plant diseases.

Book excerpt: VIRUS DISEASES OF PLANTS VIRUS DISEASES OF PLANTS BY JOHN GRAINGER PH. D., B. Sc. OXFORD UNIVERSITY PRESS LONDON HUMPHREY MILFORD 1934 PREFACE THE need for a small book upon the subject of Plant Virus Diseases appeared during my teaching work at Leeds University and in the County of Yorkshire. The study of this subject is, indeed, developing rapidly, but it seemed that this was not sufficient justification for with holding a simple text-book from the student of Mycology or Plant Pathology. A comprehensive volume would be inappropriate, as yet, and would have a limited use. The aim of this book has therefore been to introduce the student to the phenorrfcria associated with Virus Diseases, rather than to provide him with descriptions of all known viroses it is typical rather than complete. Many pitfalls aw r ait the new worker on Virus Diseases, so it was decided to include descriptions of the various items of technique in common use. The list of references at the end of the volume will provide an introduction to the very extensive literature on the subject of Plant Viruses. In its compilation, accessibility and comprehensiveness o the papers quoted have been constantly in mind. The references cited in the text follow the general plan of the book, being representative, not exhaustive. It is with great pleasure that I acknowledge my in debtedness to many persons to my wife, for much con structive criticism and help, and to Dr. J. Henderson Smith, of Rothamsted, who criticized the manuscript in its early stages. Dr. J. Johnson, of Wisconsin University, U. S. A., has helped in ways too numerous to mention, and Prof. J. H. Priestley, of Leeds University, introduced me to the study of VirusDiseases of Plants, and helped consider ably in its prosecution. Many workers in Ireland, Holland, America, Germany, and our own country have given written and verbal communication of their results. The Oxford University Press has throughout been most cour teous and helpful. J-G - June, 1933. J CONTENTS . INTRODUCTORY. Historical i II.

Available in PDF, EPUB and Kindle. Book excerpt: The book is a compilation of research work carried out on plant viruses during past 100 years in India. Plant viruses are important constraints in Indian agriculture. Tropical and sub-tropical environments and intensive crop cultivation practices ideally favours perpetuation of numerous plant viruses and their vectors in India, which often cause wide spread crop losses. Of all the plant pathogens, studies of plant viruses have received a special attention as they are difficult to manage. A large body of literature has been published on the plant virus research from India during past 100 years; however the information is so far not available in one place. This book provides comprehensive information on the biology, molecular biology, epidemics, crop losses, diagnosis and management of viruses and viroids occurring in India. Description of properties of the viruses are provided in the chapters comprising of different genera such as Allexivirus, Begomovirus, Babuvirus, Badnavirus, Carlavirus, Carmovirus, Cucumovirus, Closterovirus, Ilavirus, Mandrivirus, Potyvirus, Tospovirus, Tungrovirus and Sobemovirus. Virus-vector research related to aphid, thrips and whitefly is discussed. The work on the management aspects of plant viral diseases has been described with reference to the conventional, antiviral and transgenic approaches. Further, the quarantine mechanism developed in India for the exclusion of viruses and vectors has also been included. The book also provides useful information about the capacity building on the research and education on Plant Virology in India. Overall, the book covers a wide range of accounts of research findings and innovations in Plant Virology in India during past 100 years. The book will be a resourceful reference to the students, scientists, agricultural professionals and policy makers.

Available in PDF, EPUB and Kindle. Book excerpt: Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.
