Bromoviridae Virion
''Bromoviridae'' is a family of viruses. Plants serve as natural hosts. There are six genera in the family. Taxonomy The following genera are assigned to the family: * ''Alfamovirus'' * ''Anulavirus'' * ''Bromovirus'' * ''Cucumovirus'' * ''Ilarvirus'' * ''Oleavirus'' Structure Viruses in the family ''Bromoviridae'' are non-enveloped, with icosahedral and bacilliform geometries. The diameter is around 26-35 nm. Genomes are linear and segmented, tripartite. Life cycle Viral replication is cytoplasmic, and is lysogenic. 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, using the internal initiation model of subgenomic rna transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement. Plants serve as the natural host. Transmission routes are mechanical and contact. References External li ...

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living Cell (biology), cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. 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, more than 16,000 of the millions of List of virus species, virus species have been described in detail. 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 viral particles, or ''virions'', consisting of (i) genetic material, i.e., long ...

Closteroviridae
''Closteroviridae'' is a family of viruses. Plants serve as natural hosts. There are seven genera in this family. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem. Taxonomy Genome type and transmission vector are two of the most important traits used for classification. Ampeloviruses and Closteroviruses have monopartite genomes and are transmitted by pseudococcid mealybugs (and soft scale insects) and aphid Aphids are small sap-sucking insects in the Taxonomic rank, family Aphididae. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white Eriosomatinae, woolly ...s respectively. While Criniviruses are bipartite and transmitted by whiteflies. The family contains the following genera: * '' Ampelovirus'' * '' Bluvavirus'' * '' Closterovirus'' * '' Crinivirus'' * '' Menthavirus'' * '' Olivavirus'' * '' Velarivirus'' Structure Viruses ...

Endornaviridae
''Endornaviridae'' is a family of viruses. Plants, fungi, and oomycetes serve as natural hosts. There are 31 species in this family, assigned to 2 genera (''Alphaendornavirus'' and ''Betaendornavirus''). Members of ''Alphaendornavirus'' infect plants, fungi and the oomycete ''Phytophthora'' sp., members of ''Betaendornavirus'' infect Ascomycetes, ascomycete fungi.ICTVdB Management (2006). 00.108.0.01. Endornavirus. In: ICTVdB—The Universal Virus Database, version 4. Büchen-Osmond, C. (Ed), Columbia University, New York, USA. Taxonomy The following genera are assigned to the family: * ''Alphaendornavirus'' * ''Betaendornavirus'' Structure Linear, single-stranded, positive-sense RNA genome of about 14 kb to 17.6 kb. A site specific break (nick) is found in the coding strand about 1 to 2 kb from the Five-prime cap, 5’ terminus. ViralZone conflicts with ICTV, listing ''Endornaviridae'' as dsRNA viruses. As the ''Endornaviridae'' genomes don't include a capsid, coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virgaviridae
''Virgaviridae'' is a family of positive-strand RNA viruses. Plants serve as natural hosts.Adams MJ, Antoniw JF, Kreuze J (2009) Virgaviridae: a new family of rod-shaped plant viruses. Arch Virol 154(12):1967–1972 The name of the family is derived from the Latin word ''virga'' (rod), as all viruses in this family are rod-shaped. There are currently 59 species in this family, divided among seven genera. Structure 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 suppression of termination. The virus exits the host cell by tripartite non-tubule guided viral movement, and monopartite non-tubule guided viral movement. Plants serve as the natural host.
