Alphatetraviridae
''Alphatetraviridae'' is a family of viruses. Moths and butterflies serve as natural hosts. There are two genera in the family. Infection outcome varies from unapparent to lethal. Taxonomy The following genera are assigned to the family: *''Betatetravirus'' *''Omegatetravirus'' Structure Viruses in ''Alphatetraviridae'' are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear and non-segmented, bipartite, around 6.5kb in length. Life cycle Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription is the method of transcription. Translation takes place by leaky scanning, and ribosomal skipping. Moths and butterflies serve as the natural host. Transmission routes are oral. References External links Viralzone: AlphatetraviridaeICTV {{Taxonbar, fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of 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.e ...

Helicoverpa Armigera Stunt Virus
''Helicoverpa'' is a genus of moths in the family Noctuidae first described by David F. Hardwick in 1965. Some species are among the worst Lepidopteran agricultural pests in the world, and three species (''H. armigera'', ''H. zea'', and ''H. punctigera'') migrate long distances both with and without human transportation, mixing resistance alleles along the way. Extant species * ''Helicoverpa armigera'' (Hübner, 1805) - cotton bollworm * '' Helicoverpa assulta'' (Guenée, 1852) * ''Helicoverpa atacamae'' Hardwick, 1965 * ''Helicoverpa fletcheri'' Hardwick, 1965 * ''Helicoverpa gelotopoeon'' (Dyar, 1921) * ''Helicoverpa hardwicki'' Matthews, 1999 * ''Helicoverpa hawaiiensis'' Quaintance & Brues, 1905 * ''Helicoverpa helenae'' Hardwick, 1965 * ''Helicoverpa pallida'' Hardwick, 1965 * ''Helicoverpa prepodes'' Common, 1985 * '' Helicoverpa punctigera'' Wallengren, 1860 * ''Helicoverpa titicacae'' * ''Helicoverpa toddi'' Hardwick, 1965 * '' Helicoverpa zea'' Boddie, 1850 Extinct sp ...
