This book was released on 2013-06-26 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the world's population. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses. For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.

Download or read book Host Pathogen Interaction Regulating the Replication of Bromoviridae Family written by Sonali Anilkumar Chaturvedi and published by . This book was released on 2014 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positive sense RNA viruses play a central role in the field of virology in general and agriculture in particular. Cucumber mosaic virus (CMV) is a positive sense RNA virus, playing an important role in agriculture because of its broad host range, as it can infect over 1200 species of plants. CMV is sometime accompanied by satellite RNA, a 336 nucleotides long noncoding RNA, which can either ameliorate or intensify symptom expression by the virus. CMV is a multipartite virus, requiring a constellation of three virion particles to initiate a successful infection. Chapter 1 of this dissertation focuses on optimization the Agrobacterium cell concentration of three genomic RNA agroconstructs of Brome mosaic virus (BMV), a widely used model system to study replication, recombination and packaging in positive sense RNA viruses. In this chapter, the focus is made on understanding effect of optical density (O.D 600 ) of Agrobacterium cell cultures on synchronized infection followed viral gene expression. Chapter 2 is largely focused on understanding the mechanism regulating nuclear import of satellite RNA (satRNA) in the presence and absence of CMV. It was identified that Bromodomain containing RNA binding protein (BRP1), an ortholog of which has been previously documented to play an important role in the life cycle of Potato Spindle Tuber Viroid (PSTVd), plays a crucial role in the nuclear import of satRNA. Information garnered in this chapter helped bridging the evolutionary gap between satellite RNA and PSTVd. In Chapter 3, an attempt is made to understand the proteome interacting with BRP1, whose functionality in a plant is yet unknown. By using proteomic approaches, we were able to understand proteome interacting with BRP1 by itself, or in the presence of CMV or satellite RNA in Nicotiana benthamiana plants. Chapter 4 is an extension of chapter 3, where single gene knockout lines of Arabidopsis thaliana of short listed host proteins from chapter 3 were tested for their role in CMV replication, and specificaly the role of Glyceraldehyde 3 phosphate dehydrogenase (GAPDH) in replicase complex assembly/stability was studied. Understanding the shift in proteome of host in case of a satRNA is a daunting task (due to the inability of satRNA to code for proteins), hence, we employed riboproteomic approach in Chapter 5 to short list host proteins interacting with satellite RNA in plus- or minus- sense, in the presence or absence of CMV. Viral protein-protein interactions play an important role in the replication of positive sense RNA viruses. Chapter 6, and 7 focus on comparative study of protein protein interactions for two important members of Bromoviridae family. In chapter 6, live cell imaging using BiFC analysis helped us visualize protein protein interactions and subcellular localization of BMV proteins.. Finally, in Chapter 7, we provide an extensive protein-protein interaction study of CMV viral proteins in vivo using Bimolecular Fluorescence complementation (BiFC) assay.

Available in PDF, EPUB and Kindle. Book excerpt: The practical need to partition the world of viruses into distinguishable, universally agreed upon entities is the ultimate justification for developing a virus classification system. Since 1971, the International Committee on Taxonomy of Viruses (ICTV) operating on behalf of the world community of virologists has taken on the task of developing a single, universal taxonomic scheme for all viruses infecting animals (vertebrate, invertebrates, and protozoa), plants (higher plants and algae), fungi, bacteria, and archaea. The current report builds on the accumulated taxonomic construction of the eight previous reports dating back to 1971 and records the proceedings of the Committee since publication of the last report in 2005. Representing the work of more than 500 virologists worldwide, this report is the authoritative reference for virus organization, distinction, and structure.

Download or read book The Biological Role of a Virus written by Christon J. Hurst and published by Springer Nature. This book was released on 2022-02-12 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book answers the question “What is it that viruses do?” by presenting three aspects of viral ecology. The first aspect explains how viruses affect the population diversity and energetics of their host communities. Perhaps the most notable example of this concept is our understanding that primary production within ecosystems often depends upon those viruses which serve as controllers of nutrient recycling, connecting the aquatic and terrestrial realms in ways that can be assessed locally and globally. The second aspect describes genetic partnerships which exist between hosts and their viruses. These include processes termed endogeny and lysogeny by which the host carries at least a partial genomic copy of the virus. Fluidity of these collective genomes is expressed on an evolutionary time scale and the mutual life cycles which they produce represent a forging of shared genomic fate that obligates partnership of the virus and its host. The viral sequences represent a source of potential benefit as well as potential peril for the host and can implement phenotypic changes in the host. Hosts often use those changes as tools. As humans, the most notable example would be that mammals rely upon temporary activation of their endogenous viral genes in order to successfully develop a placenta. The third aspect is defending the health of a host, which relies upon activity in two directions. Hosts often use their captured viral genes to identify and subsequently direct battle against invading viruses. This natural concept has been engineered for combating cancer, is useful for suppressing the detrimental consequences of genetic diseases, and has been developed to create targeted antiviral vaccines. But, the defense has to work in two directions and the host can use other symbiotic microorganisms as protection against its viruses. This book will appeal to a wide readership by providing a broad perspective of viral ecology, and all scientists will find it helpful for gaining a view of fields beyond their specialization.
