Aureusvirus
''Aureusvirus'' is a genus of viruses, in the family ''Tombusviridae''. Plants serve as natural hosts. There are six species in this genus. Taxonomy The genus contains the following species: * '' Cucumber leaf spot virus'' * '' Elderberry aureusvirus 1'' * '' Johnsongrass chlorotic stripe mosaic virus'' * ''Maize white line mosaic virus'' * '' Pothos latent virus'' * ''Yam spherical virus Yam or YAM may refer to: Plants and foods *Yam (vegetable), common name for members of ''Dioscorea'' * Taro, known in Malaysia and Singapore as yam *Sweet potato, specifically its orange-fleshed cultivars, often referred to as yams in North Ameri ...'' Structure Viruses in ''Aureusvirus'' are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 30 nm. Genomes are linear, around 4.4kb in length. Life cycle Viral replication is cytoplasmic, and is lysogenic. Entry into the host cell is achieved by penetration into the host cell. Replicatio ...

Tombusviridae
''Tombusviridae'' is a family of single-stranded positive sense RNA plant viruses. There are three subfamilies, 17 genera, and 95 species in this family. The name is derived from ''Tomato bushy stunt virus'' (TBSV). Genome All viruses in the family have a non-segmented (monopartite) linear genome, with the exception of Dianthoviruses, whose genome is bipartite. The genome is approximately 4.6–4.8kb in length, lacks a 5' cap and a poly(A) tail, and it encodes 4–6 ORFs. The polymerase encodes an amber stop codon which is the site of a readthrough event within ORF1, producing two products necessary for replication. There is no helicase encoded by the virus.

Maize White Line Mosaic Virus

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 ...

Cucumber (''Cucumis sativus'') is a widely-cultivated creeping vine plant in the Cucurbitaceae family that bears usually cylindrical fruits, which are used as culinary vegetables.Cucumber " ''''. 2019. Considered an annual plant, there are three main varieties of cucumber—slicing, , and |
Elderberry Aureusvirus 1
''Sambucus'' is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus ''Adoxa''. Description The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white). Color Sambucus fruit is rich in anthocyanidinsColors Derived from Agricultural Products |
Johnsongrass Chlorotic Stripe Mosaic Virus
Johnson grass or Johnsongrass, ''Sorghum halepense'', is a plant in the grass family, Poaceae, native to Asia and northern Africa. The plant has been introduced to all continents except Antarctica, and most larger islands and archipelagos. It reproduces by rhizomes and seeds. Johnson grass has been used for forage and to stop erosion, but it is often considered a weed because: * Foliage that becomes wilted from frost or hot, dry weather can contain sufficient amounts of hydrogen cyanide to kill cattle and horses if it is eaten in quantity. * The foliage can cause 'bloat' in such herbivores from the accumulation of excessive nitrates; otherwise, it is edible. * It grows and spreads rapidly, it can 'choke out' other cash crops planted by farmers. This species occurs in crop fields, pastures, abandoned fields, rights-of-way, forest edges, and along streambanks. It thrives in open, disturbed, rich, bottom ground, particularly in cultivated fields. Johnson grass that is resistant to ...
