Viruses: Biology, Applications, and Control

Whole-genome sequences are now achievable within days and available for multiple pathogens, including those that cause neglected tropical diseases, which has advanced our understanding of the biology and evolution of pathogens. Crucially, such research has enabled important advances in the clinical management of infectious diseases, and continues to guide public health interventions worldwide. Here, Genome Biology and Genome Medicine take stock of where we are now, with a collection of articles that discuss different aspects of the genomics of infectious diseases in human populations, including the progress made towards their eradication, and the remaining challenges in terms of both fundamental science and clinical management. The increasing availability of sequence data for many viruses provides power to detect regions under unusual evolutionary constraint at a high resolution. One approach leverages the synonymous substitution rat Citation: Genome Biology 16 Content type: Method.

Plants, plant viruses, and their vectors are co-evolving actors that co-exist and interact in nature. Insects are the most important vectors of plant viruses, serving as both carriers and hosts for the virus. This trans- kingdom interaction can be harnessed for the production of recombinant plant viruses designed to target insect genes via the RNAi machinery. The selection of the adequate viruses is important since they must infect and preferentially replicate in both the host plant and the insect vector. The routes of transmission that determine the extent of the infection inside the insect vary among different plant viruses. In the context of the proposed strategy, plant viruses that are capable of transversing the insect gut-hemocoel barrier and replicating in insect tissues are attractive candidates.

Tobacco mosaic virus TMV is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as " mosaic "-like mottling and discoloration on the leaves hence the name. TMV was the first virus to be discovered. Although it was known from the late 19th century that a non-bacterial infectious disease was damaging tobacco crops, it was not until that the infectious agent was determined to be a virus. It is the first pathogen identified as a virus. In , Adolf Mayer first described the tobacco mosaic disease that could be transferred between plants, similar to bacterial infections. In , Martinus Beijerinck independently replicated Ivanovsky's filtration experiments and then showed that the infectious agent was able to reproduce and multiply in the host cells of the tobacco plant.

Viruses: Biology, Applications, and Control / Edition 1

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. When infected, a host cell is forced to rapidly produce thousands of identical copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions , consisting of: i the genetic material , i.

Exploitation of Microorganisms pp Cite as. Virus diseases of insects and their role in the natural regulation of insect populations have been recognized for many years. When the virulence and insect-specific nature of some viruses was appreciated, research intensified on their potential as biological control agents and numerous field trials were carried out between and Ignoffo, Viral insecticides, however, failed to become commercially successful at this time probably because of the simultaneous development of numerous synthetic pesticides with broad spectrum, low cost and high insecticidal activity.


Poliovirus , the causative agent of polio also known as poliomyelitis , is a serotype of the species Enterovirus C , in the family of Picornaviridae. Poliovirus is composed of an RNA genome and a protein capsid. Because of its short genome and its simple composition—only RNA and a nonenveloped icosahedral protein coat that encapsulates it, poliovirus is widely regarded as the simplest significant virus.

Пуст был и вращающийся стул Мидж. Звуки шли сверху. Он поднял глаза на видеомониторы, и у него закружилась голова. Одна и та же картинка смотрела на него со всех двенадцати мониторов наподобие какого-то извращенного балета. Вцепившись руками в спинку стула, Бринкерхофф в ужасе смотрел на экраны.
