  • Chapter Five - Evolution of the Large Nucleocytoplasmic DNA Viruses of
           Eukaryotes and Convergent Origins of Viral Gigantism
    • Abstract: Publication date: 2019Source: Advances in Virus Research, Volume 103Author(s): Eugene V. Koonin, Natalya YutinAbstractThe Nucleocytoplasmic Large DNA Viruses (NCLDV) of eukaryotes (proposed order “Megavirales”) comprise an expansive group of eukaryotic viruses that consists of the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Marseilleviridae, Pithoviridae, and Mimiviridae, as well as Pandoraviruses, Molliviruses, and Faustoviruses that so far remain unaccounted by the official virus taxonomy. All these viruses have double-stranded DNA genomes that range in size from about 100 kilobases (kb) to more than 2.5 megabases. The viruses with genomes larger than 500 kb are informally considered “giant,” and the largest giant viruses surpass numerous bacteria and archaea in both particle and genome size. The discovery of giant viruses has been highly unexpected and has changed the perception of viral size and complexity, and even, arguably, the entire concept of a virus. Given that giant viruses encode multiple proteins that are universal among cellular life forms and are components of the translation system, the quintessential cellular molecular machinery, attempts have been made to incorporate these viruses in the evolutionary tree of cellular life. Moreover, evolutionary scenarios of the origin of giant viruses from a fourth, supposedly extinct domain of cellular life have been proposed. However, despite all the differences in the genome size and gene repertoire, the NCLDV can be confidently defined as monophyletic group, on the strength of the presence of about 40 genes that can be traced back to their last common ancestor. Using several most strongly conserved genes from this ancestral set, a well-resolved phylogenetic tree of the NCLDV was built and employed as the scaffold to reconstruct the history of gene gain and loss throughout the course of the evolution of this group of viruses. This reconstruction reveals extremely dynamic evolution that involved extensive gene gain and loss in many groups of viruses and indicates that giant viruses emerged independently in several clades of the NCLDV. Thus, these giants of the virus world evolved repeatedly from smaller and simpler viruses, rather than from a fourth domain of cellular life, and captured numerous genes, including those for translation system components, from eukaryotes, along with some bacterial genes. Even deeper evolutionary reconstructions reveal apparent links between the NCLDV and smaller viruses of eukaryotes, such as adenoviruses, and ultimately, derive all these viruses from tailless bacteriophages.
       
  • Chapter Four - The Complex Nature of Tupanviruses
    • Abstract: Publication date: 2019Source: Advances in Virus Research, Volume 103Author(s): Rodrigo Araújo Lima Rodrigues, Thalita Souza Arantes, Graziele Pereira Oliveira, Ludmila Karen dos Santos Silva, Jônatas Santos AbrahãoAbstractThe discovery of giant viruses revealed a new level of complexity in the virosphere, raising important questions about the diversity, ecology, and evolution of these viruses. The family Mimiviridae was the first group of amoebal giant viruses to be discovered (by Bernard La Scola and Didier Raoult team), containing viruses with structural and genetic features that challenged many concepts of classic virology. The tupanviruses are among the newest members of this family and exhibit structural, biological, and genetic features never previously observed in other giant viruses. The complexity of these viruses has put us one step forward toward the comprehension of giant virus biology and evolution, but also has raised important questions that still need to be addressed. In this chapter, we tell the history behind the discovery of one of the most complex viruses isolated to date, highlighting the unique features exhibited by tupanviruses, and discuss how these giant viruses have contributed to redefining limits for the virosphere.
       
  • Chapter Three - Eukaryotic Circular Rep-Encoding Single-Stranded DNA
           (CRESS DNA) Viruses: Ubiquitous Viruses With Small Genomes and a Diverse
           Host Range
    • Abstract: Publication date: 2019Source: Advances in Virus Research, Volume 103Author(s): Lele Zhao, Karyna Rosario, Mya Breitbart, Siobain DuffyAbstractWhile single-stranded DNA (ssDNA) was once thought to be a relatively rare genomic architecture for viruses, modern metagenomics sequencing has revealed circular ssDNA viruses in most environments and in association with diverse hosts. In particular, circular ssDNA viruses encoding a homologous replication-associated protein (Rep) have been identified in the majority of eukaryotic supergroups, generating interest in the ecological effects and evolutionary history of circular Rep-encoding ssDNA viruses (CRESS DNA) viruses. This review surveys the explosion of sequence diversity and expansion of eukaryotic CRESS DNA taxonomic groups over the last decade, highlights similarities between the well-studied geminiviruses and circoviruses with newly identified groups known only through their genome sequences, discusses the ecology and evolution of eukaryotic CRESS DNA viruses, and speculates on future research horizons.
       
  • Chapter Two - Phage Lysis: Multiple Genes for Multiple Barriers
    • Abstract: Publication date: 2019Source: Advances in Virus Research, Volume 103Author(s): Jesse Cahill, Ry YoungAbstractThe first steps in phage lysis involve a temporally controlled permeabilization of the cytoplasmic membrane followed by enzymatic degradation of the peptidoglycan. For Caudovirales of Gram-negative hosts, there are two different systems: the holin-endolysin and pinholin-SAR endolysin pathways. In the former, lysis is initiated when the holin forms micron-scale holes in the inner membrane, releasing active endolysin into the periplasm to degrade the peptidoglycan. In the latter, lysis begins when the pinholin causes depolarization of the membrane, which activates the secreted SAR endolysin. Historically, the disruption of the first two barriers of the cell envelope was thought to be necessary and sufficient for lysis of Gram-negative hosts. However, recently a third functional class of lysis proteins, the spanins, has been shown to be required for outer membrane disruption. Spanins are so named because they form a protein bridge that connects both membranes. Most phages produce a two-component spanin complex, composed of an outer membrane lipoprotein (o-spanin) and an inner membrane protein (i-spanin) with a predominantly coiled-coil periplasmic domain. Some phages have a different type of spanin which spans the periplasm as a single molecule, by virtue of an N-terminal lipoprotein signal and a C-terminal transmembrane domain. Evidence is reviewed supporting a model in which the spanins function by fusing the inner membrane and outer membrane. Moreover, it is proposed that spanin function is inhibited by the meshwork of the peptidoglycan, thus coupling the spanin step to the first two steps mediated by the holin and endolysin.
       
  • Chapter One - The Diverse Impacts of Phage Morons on Bacterial Fitness and
           Virulence
    • Abstract: Publication date: 2019Source: Advances in Virus Research, Volume 103Author(s): Véronique L. Taylor, Alexa D. Fitzpatrick, Zafrin Islam, Karen L. MaxwellAbstractThe viruses that infect bacteria, known as phages, are the most abundant biological entity on earth. They play critical roles in controlling bacterial populations through phage-mediated killing, as well as through formation of bacterial lysogens. In this form, the survival of the phage depends on the survival of the bacterial host in which it resides. Thus, it is advantageous for phages to encode genes that contribute to bacterial fitness and expand the environmental niche. In many cases, these fitness factors also make the bacteria better able to survive in human infections and are thereby considered pathogenesis or virulence factors. The genes that encode these fitness factors, known as “morons,” have been shown to increase bacterial fitness through a wide range of mechanisms and play important roles in bacterial diseases. This review outlines the benefits provided by phage morons in various aspects of bacterial life, including phage and antibiotic resistance, motility, adhesion and quorum sensing.

  • Chapter Eight - Integration of Omics Approaches toward Understanding
           Whitefly Transmission of Viruses
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): William M. WintermantelAbstractViruses transmitted by whiteflies are predominantly classified as having either persistent circulative or semipersistent transmission, and the majority of studies have addressed transmission of viruses in the genera Begomovirus (family Geminiviridae) and Crinivirus (family Closteroviridae), respectively. Early studies on vector transmission primarily addressed individual aspects of transmission; however, with the breadth of new technology now available, an increasingly greater number of studies involve coordinated research that is beginning to assemble a more complete picture of how whiteflies and viruses have coevolved to facilitate transmission. In particular the integration of gene expression and metabolomic studies into broader research topics is providing knowledge of changes within the whitefly vector in response to the presence of viruses that would have been impossible to identify previously. Examples include comparative studies on the response of Bemisia tabaci to begomovirus and crinivirus infection of common host plants, evolution of whitefly endosymbiont relationships, and opportunities to evaluate responses to specific transmission-related events. Integration of metabolomics, as well as the application of electrical penetration graphing, can lead to an ability to monitor the changes that occur in vector insects associated with specific aspects of virus transmission. Through gaining more complete knowledge of the mechanisms behind whitefly transmission of viruses new control strategies will undoubtedly emerge for control of whiteflies and the viruses they transmit.
       
  • Chapter Seven - Viral Manipulation of Plant Stress Responses and Host
           Interactions With Insects
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): John P. Carr, Ruairí Donnelly, Trisna Tungadi, Alex M. Murphy, Sanjie Jiang, Ana Bravo-Cazar, Ju-Yeon Yoon, Nik J. Cunniffe, Beverley J. Glover, Christopher A. GilliganAbstractDo the alterations in plant defensive signaling and metabolism that occur in susceptible hosts following virus infection serve any purpose beyond directly aiding viruses to replicate and spread' Or indeed, are these modifications to host phenotype purely incidental consequences of virus infection' A growing body of data, in particular from studies of viruses vectored by whiteflies and aphids, indicates that viruses influence the efficiency of their own transmission by insect vectors and facilitate mutualistic relationships between viruses and their insect vectors. Furthermore, it appears that viruses may be able to increase the opportunity for transmission in the long term by providing reward to the host plants that they infect. This may be conditional, for example, by aiding host survival under conditions of drought or cold or, more surprisingly, by helping plants attract beneficial insects such as pollinators. In this chapter, we cover three main areas. First, we describe the molecular-level interactions governing viral manipulation of host plant biology. Second, we review evidence that virus-induced changes in plant phenotype enhance virus transmission. Finally, we discuss how direct and indirect manipulation of insects and plants might impact on the evolution of viruses and their hosts.
       
  • Chapter Six - TMV Particles: The Journey From Fundamental Studies to
           Bionanotechnology Applications
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): George P. Lomonossoff, Christina WegeAbstractEver since its initial characterization in the 19th century, tobacco mosaic virus (TMV) has played a prominent role in the development of modern virology and molecular biology. In particular, research on the three-dimensional structure of the virus particles and the mechanism by which these assemble from their constituent protein and RNA components has made TMV a paradigm for our current view of the morphogenesis of self-assembling structures, including viral particles. More recently, this knowledge has been applied to the development of novel reagents and structures for applications in biomedicine and bionanotechnology. In this article, we review how fundamental science has led to TMV being at the vanguard of these new technologies.
       
  • Chapter Five - Dichorhaviruses in their Host Plants and Mite Vectors
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): Ralf G. Dietzgen, Juliana Freitas-Astúa, Camila Chabi-Jesus, Pedro L. Ramos-González, Michael M. Goodin, Hideki Kondo, Aline D. Tassi, Elliot W. KitajimaAbstractA group of related bacilliform, nuclear viruses with a bisegmented negative-sense RNA genome that are transmitted by Brevipalpus mites likely in a circulative–propagative manner were recently classified in the new genus Dichorhavirus, family Rhabdoviridae. These viruses cause localized lesions on leaves, stems, and fruits of economically significant horticultural and ornamental plant species. Among its members, orchid fleck virus, citrus leprosis virus N, and coffee ringspot virus are most prominent. This chapter summarizes the current knowledge about these viruses, available detection techniques, and their interactions with their plant hosts and mite vectors.
       
  • Chapter Four - Tobamoviruses as Models for the Study of Virus Evolution
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): Aurora Fraile, Fernando García-ArenalAbstractThe study of tobacco mosaic virus and other tobamovirus species has greatly contributed to the development of all areas of virology, including virus evolution. Research with tobamoviruses has been pioneer, or particularly significant, in all major areas of research in this field, including: the characterization of the genetic diversity of virus populations, the mechanisms and rates of generation of genetic diversity, the analysis of the genetic structure of virus populations and of the factors that shape it, the adaptation of viruses to hosts and the evolution of host range, and the evolution of virus taxa and of virus–host interactions. Many of these continue to be hot topics in evolutionary biology, or have been identified recently as such, including (i) host-range evolution, (ii) predicting the overcoming of resistance in crops, (iii) trade-offs between virus life-history traits in virus evolution, and (iv) the codivergence of viruses and hosts at different taxonomical and spatial scales. Tobamoviruses may be particularly appropriate to address these topics with plant viruses, as they provide convenient experimental systems, and as the detailed knowledge on their molecular and structural biology allows the analysis of the mechanisms behind evolutionary processes. Also, the extensive information on parameters related to infection dynamics and population structure may facilitate the development of realistic models to predict virus evolution. Certainly, tobamoviruses will continue to be favorite system for the study of virus evolution.
       
  • Chapter Three - Molecular Modeling for Better Understanding of Cucumovirus
           Pathology
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): Katalin Salánki, Ákos Gellért, Katalin Nemes, Zoltán Divéki, Ervin BalázsAbstractCucumber mosaic virus (CMV) is a small RNA virus capable of infecting a wide variety of plant species. The high economic losses due to the CMV infection made this virus a relevant subject of scientific studies, which were further facilitated by the small size of the viral genome. Hence, CMV also became a model organism to investigate the molecular mechanism of pathogenesis. All viral functions are dependent on intra- and intermolecular interactions between nucleic acids and proteins of the virus and the host. This review summarizes the recent data on molecular determinants of such interactions. A particular emphasis is given to the results obtained by utilizing molecular-based planning and modeling techniques.
       
  • Chapter Two - Development of Model Systems for Plant Rhabdovirus Research
    • Abstract: Publication date: 2018Source: Advances in Virus Research, Volume 102Author(s): Andrew O. Jackson, Ralf G. Dietzgen, Michael M. Goodin, Zhenghe LiAbstractThis chapter reviews the discoveries and initial characterizations (1930–1990) of three plant rhabdoviruses, sonchus yellow net virus, potato yellow dwarf virus, and lettuce necrotic yellows virus, that have become model systems for research on this group of enveloped negative-strand RNA plant viruses. We have used our personal perspectives to review the early historical studies of these viruses, the important technologies and tools, such as density gradient centrifugation, that were developed during the research, and to highlight the eminent scientists involved in these discoveries. Early studies on sites of virus replication, virion structure, physicochemical composition, and the use of protoplasts and vector insect cell culture for virus research are discussed, and differences between the nuclear and cytoplasmic lifestyles of plant rhabdoviruses are contrasted. Finally, we briefly summarize the genome organization and more recent developments culminating in the development of a reverse genetics system for plant negative-strand RNA viruses.
