Carlavirus
''Carlavirus'', formerly known as the "Carnation latent virus group", is a genus of viruses in the order ''Tymovirales'', in the family ''Betaflexiviridae''. Plants serve as natural hosts. There are 53 species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms. Description ''Carlavirus'' is described in the 9th report of the ICTV (2009). The genus is characterised by having six ORFs (open reading frames) including a TGB ( Triple Gene Block). The viruses are transmitted by insects. Taxonomy The genus was first proposed in the first report of the ICTV in 1971, as the 'Carnation latent virus group' but was renamed in 1975 as the 'Carlavirus group', and as the genus ''Carlavirus'' in 1995 (6th report). In 2005 (8th report) it was placed in the '' Flexiviridae'' family, having previously been unassigned. The current position in the 9th report (2009) as a genus of the family ''Betaflexiviridae'' derives from the subsequent subdivision of ''Flexivi ...

Tymovirales
''Tymovirales'' is an order of viruses with five families. The group consists of viruses which have positive-sense, single-stranded RNA genomes. Their genetic material is protected by a special coat protein. Description Tymoviruses are mainly plant pathogens first described in 2004. They are characterised by similarities in their replication-associated polyproteins. These account for the majority of their genomic coding capacity. They are considered to form a group, phylogenetically, referred to as flexiviruses, with filamentous virions 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 ....

Banana Mild Mosaic Virus
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus '' Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – '' Musa acuminata'' and '' Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banana Virus X
Banana virus X (BVX) is a plant virus that infects members of the genus '' Musa''. Its genome is about 2,900 nucleotides in length and contains five open reading frames that encode for a replication-associated protein, a movement-associated triple gene block and a capsid protein. A polyvalent degenerate oligonucleotide reverse transcription polymerase chain reaction Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase cha ... (PDO-RT-PCR) assay has been developed to detect BVX nucleic acid in infected leaves. The virus was originally discovered in Guadeloupe.

Sugarcane Striate Mosaic-associated Virus
Sugarcane or sugar cane is a species of (often hybrid) tall, perennial grass (in the genus '' Saccharum'', tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. The plant is also grown for biofuel production, especially in Brazil, as the canes can be used directly to produce ethyl alcohol ( ethanol). Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. Sugarcane accounts for 79% of sugar produced globally (most of the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
