Principles of Plant Virology: Genome, Pathogenicity, Virus Ecology presents the specific collaborations and the defensive and counter-defensive interactions that govern the virus intercellular cycle and plant infection. It describes the relationship between the virus and the agro-environment and presents recent development in diagnosis and control methods.It also provides detailed information on plant virus evolution and taxonomy. This book is an indispensable guide for teachers, undergraduate and graduate students, and scientists in the fields of virology, plant pathology, microbiology, and plant biology. Contents
THE VIRUS, THE CELL AND THE PLANT
1. Viral Structures Architecture of the virion Viral nucleic acids Viral information: a protected message
2. Infection of the Cell: Synthesis of Viral Proteins Entry of viral genetic information into the cell Translation of the viral messenger
3. Infection of the Cell: Replication of the Viral Nucleic Acid Replication of positive-sense RNA viruses Replication of negative-sense RNA viruses Replication of single-stranded DNA viruses: Geminiviridae and Nanoviridae Replication of double-stranded DNA viruses: Caulimoviridae Conclusion
4. Plant Virus Movement TMV movement: a model system The movement of other viruses Another form of cell-to-cell movement: the viral particle Virus movement: a paradigm for macromolecular trafficking within plants Concluding remarks
5. The Defense Reaction of the Infected Plant Recovery from viral infection is due to an RNA silencing mechanism similar to post-transcriptional gene silencing (PTGS) Viruses can suppress RNA silencing Concluding remarks: RNA silencing, the tip of the iceberg?
6. Resistance with Hypersensitivity Reaction and Extreme Resistance Description of resistance Induction of resistance Signal Transduction The expression of resistance Conclusion
7. Subviral Pathogenic RNAs: Satellites and Viroids Satellite viruses and satellite RNAs Viroids
THE VIRUS IN THE AGRO-ENVIRONMENT
8. Virus Dissemination To be transmitted or to disappear: a dilemma for plant viruses Specific molecular interactions between viruses and vectors The epidemiology of viral diseases
9. Diagnostic Methods Symptoms observed on the plant Symptoms observed at the cellular level Diagnosis through biological means Serological diagnostics methods Contribution of electron microscopy Detection of viral nucleic acids Towards efficient use of diagnostic methods
10. Control of Plant Viral Diseases: Prophylactic Measures Virus-free seeds and vegetative propagules Preventing and reducing virus dissemination
11. Controlling Plant Viral Diseases: Breeding for Resistant Varieties Search for and characterization of virus resistances Diversity of resistance mechanisms Durability of resistance genes
12. Control of Plant Viral Diseases: Genetic Engineering for Protection Gene transfer How is a transgenic plant obtained? Transgenic protection against plant viruses Potential environmental impact of virus-resistant transgenic plants
EVOLUTION AND CLASSIFICATION OF VIRUSES
13. Evolution of Viruses Mutation Recombination Viral sequences are infrequently integrated in plant DNA Viral quasi-species Vectors, a field that is constantly explored by viruses New viral diseases and emerging viruses Molecular phylogenies Origin of viruses and viral genes: modular evolution A phylum: positive-sense RNA viruses A provisional conclusion: How is a virus produced?
14. Classification of Plant Viruses Species Genera Families Orders
15. Description of Viral Genera Positive-sense single-stranded RNA viruses mainly monopartite genome, isometric particles Positive-sense single-stranded RNA viruses bipartite genome, isometric particles Positive-sense single-stranded RNA viruses tripartite genome, isometric particles Positive-sense single stranded RNA viruses helical rod-shaped particles Positive-sense single stranded RNA viruses helical filamentous particles Negative-sense single stranded RNA viruses Double-stranded RNA viruses Single-stranded DNA viruses DNA or RNA reverse-transcribing viruses
