Plant Virus
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to higher plants. Most plant viruses are rod-shaped, with protein discs forming a tube surrounding the viral genome; isometric particles are another common structure. They rarely have an envelope. The great majority have an RNA genome, which is usually small and single stranded (ss), but some viruses have double-stranded (ds) RNA, ssDNA or dsDNA genomes. Although plant viruses are not as well understood as their animal counterparts, one plant virus has become very recognizable: ''tobacco mosaic virus'' (TMV), the first virus to be discovered. This and other viruses cause an estimated US$60 billion loss in crop yields worldwide each year. Plant viruses are grouped into 73 genera and 49 families. However, these figures relate only to cultivated plants, which r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tymoviridae
''Tymoviridae'' is a family of single-stranded positive sense RNA viruses in the order ''Tymovirales''. Plants serve as natural hosts. There are 42 species in this family, assigned to three genera, with two species unassigned to a genus. Taxonomy The family includes the following three genera: * ''Maculavirus'' * ''Marafivirus'' * ''Tymovirus'' Additionally, the following two species are not assigned to a genus: * ''Bombyx mori latent virus'' * ''Poinsettia mosaic virus'' Proposed viruses * Culex tymovirusWang L, Lv X, Zhai Y, Fu S, Wang D, Rayner S, Tang Q, Liang G (2012) Genomic characterization of a novel virus of the family tymoviridae isolated from mosquitoes.

Viral Diseases Of Potato
Viral diseases of potato are a group of diseases caused by different types of viruses that affect potato crops worldwide and, although they do not affect human or animal health since they are viruses that only infect vegetables, they are a source of great economic losses annually. About 28 viruses have been reported infecting potato crops. However, potato virus X ( PVX), potato virus Y ( PVY), and potato leafroll virus ( PLRV) are the most important viruses worldwide. Some others are of economic importance only in some regions. Such is the case of potato virus M (PVM) in some Asian and European countries. An additional problem is the co-infection of two or more viruses on the same plants. In fact, the joint occurrence of PVX and PVY, or either or both of them with PLRV or Potato virus A ( PVA), produces much more severe symptoms than separate infection of each. The magnitude of economic losses associated with this synergistic effect depends on the types of viruses that are intera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
