Pea Enation Mosaic Virus 1
''Enamovirus'' is a genus of viruses, in the family '' Solemoviridae''. Plants serve as natural hosts. There are five species in this genus. Diseases associated with this genus include: pea enation disease: if both PEMV-1 and PEMV-2 are present. Taxonomy The following species are recognized: *''Alfalfa enamovirus 1'' *'' Birdsfoot trefoil enamovirus 1'' *''Citrus vein enation virus'' *''Grapevine enamovirus 1'' *''Pea enation mosaic virus Pea enation mosaic virus (PEMV) is really two plant pathogenic viruses. The two RNAs of the disease are now categorised as two separate, Mutualism (biology), mutualistic viruses: * Pea enation mosaic virus 1 is an ''Enamovirus'' * Pea enation ... 1'' Structure Viruses in ''Enamovirus'' are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 25 nm. Genomes are linear and non-segmented, around 5.7kb in length. Life cycle Viral replication is cytoplasmic. Entry into the host cell is a ...

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 ...
