Download or read book Generic Accumulation Changes of Arabidopsis Thaliana Small RNAs Due to Virus Infections written by Manpreet Singh Mallah and published by . This book was released on 2012 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In an effort to identify genetic markers for virus infection of plants, the model plant Arabidopsis thaliana was used to identify small RNAs that show generic accumulation changes in response to infection with five distinct plant viruses. The DNA virus Cauliflower mosaic virus, a negative stranded RNA virus Tomato spotted wilt virus and three unrelated positive stranded RNA viruses, Tobacco mosaic virus, Turnip mosaic virus, and Turnip yellow mosaic virus, were used to represent the wide diversity of plant viruses. Leaf tissue from plants infected with each of the five viruses and mock-inoculated plants was used for RNA isolation. RNA sequencing and radioactive northern blot hybridisation were used to identify small RNA accumulation changes over a 21-day time course. RNA sequencing identified one small RNA, miR156, that showed a significant negative fold change in all of the virus-inoculated plants compared to mock-inoculated plants. The findings from sequencing were not confirmed by northern blot analysis due to degradation of RNA in the process of hybridisation. The generic negative change in accumulation of miR156 upon virus infection identified in this study can be further investigated in other virus infections and in other plant species to determine whether it might be used as the basis of a tool to identify virus-infected plants".
Download or read book Plant Resistance to Viruses written by David Evered and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 226 pages. 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.
Download or read book Immunopathology written by and published by Academic Press. This book was released on 2020-07-23 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunopathology, Volume 107 in the Advances in Virus Research series, highlights new advances in the field, with this new volume presenting interesting chapters. Each chapter is written by an international board of authors. Viral Immunopathology will cover how the immune system, innate or adaptive, is often at the root of viral pathogenesis. This is true in diverse host systems including vertebrates, plants and insects. This volume will present the latest findings in this interesting and important area of research, and will include human, plant, fish, and insect viruses. Different kingdoms have evolved very diverse immune responses to virus infection but the common theme – namely, that effects of viruses on host immune systems can condition the induction of viral disease – will unify this concept across kingdoms. - The immune system is often responsible for virus pathology - Plants, animals and insects all mount immune responses to virus infection that can increase pathology - Both innate and adaptive immune responses can result in immunopathology

Download or read book Plant Virus Interactions written by Tatjana Kleinow and published by Springer. This book was released on 2016-01-13 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant RNA– and DNA-viruses have small genomes and with this limited coding capacity exhibit a strong dependency on host cellular processes and factors to complete their viral life cycle. Various interactions of viral proteins or nucleic acids with host components (proteins, nucleic acids, carbohydrates, lipids and metabolites) evolved, which are essential for a successful systemic spread of viruses within the plant. For example, in plants, transport of endogenous macromolecules like proteins and nucleic acids occurs in a highly selective and regulated manner and viruses exploit these specifically controlled trafficking pathways. Research on plant virus movement is located at the interface of molecular plant virology and plant cell biology. The proposed book project aims to give an overview on the current state of this research and to highlight novel insights into the dynamic interplay between plant viruses and host cells. The book is intended for researchers in plant biology and virology and especially written for those who aim to understand cell biology of virus-plant interactions.

Download or read book Begomoviruses Occurrence and Management in Asia and Africa written by Sangeeta Saxena and published by Springer. This book was released on 2017-10-14 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Begomoviruses are one of the most interesting plant viruses to study for basic and applied research as they cause huge economic losses to agriculture industries and farmers all over the world. They belong to family Geminiviridae and are emergent plant viral pathogens which cause diseases in various crops in the tropical and subtropical regions. They are transmitted by the whitefly (B. tabaci) and have either one (monopartite DNA-A) or two (bipartite DNA-A and DNA-B) genomic components. DNA-A and DNA-B are of ~2600 - 2800 nucleotides each. A number of serious diseases of cultivated crops of the Fabaceae, Malvaceae, Solanaceae and Cucurbitaceae families are caused by Begomoviruses which are considered as threat to their cultivation in many countries. Accurate diagnosis is important for successful diseases management, since plants infected by Begomovirus do not recover, suffer serious yield losses and act as further sources of inoculum, which is then picked up and spread by their vector whitefly (B. tabaci). Reports of occurrence of new viruses and re-emergence of several known viruses in new niches have become regular event. In such a dynamic system, growth of several crop species relies on an accurate diagnosis, management and better understanding of the biology of the casual virus. This is crucial to evolve appropriate control practices and to prevent the virus infection. Researchers have achieved considerable progress in characterization, detection and management of virus on different crop species in the last decade. This book covers latest information in diagnosis of begomoviruses in the present scenario and explores the new vistas in the field of genomics and proteomics. Chapters in Section 1 illustrates the occurrence, genome organisation, transmission and diagnostics of begomoviruses. It also details the diseases caused by begomoviruses on different crops, detection techniques and management strategies in support of research findings by presentation of data, graphics, figures and tables. Section 2 is a chapterwise collection of occurrence, diversity and status of begomoviruses in Asian Africa counties where the diseases are most prevalent. This book will provide wide opportunity to the readers to have complete information and status of begomovirus in Asia and Africa. This will be useful resource for researchers and extension workers involved in the begomvirus disease diagnosis and molecular biology. Expert detection, accurate diagnosis and timely management play a significant role in keeping plants free from pathogens. In this book expert researchers share their research knowledge and literature which are vital towards the diagnosis of begomoviruses, addressing traditional plant pathology techniques as well as advanced molecular diagnostic approach. The book deals with the economically important crops including fruits, vegetables along with challenges in crop protection against diseases caused by begomovirus. This will be resourceful and handy for researcher, practitioners and also students.
