Barley Yellow Dwarf Virus GPV
Barley (''Hordeum vulgare''), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago. Globally 70% of barley production is used as animal fodder, while 30% as a source of fermentable material for beer and certain distilled beverages, and as a component of various foods. It is used in soups and stews, and in barley bread of various cultures. Barley grains are commonly made into malt in a traditional and ancient method of preparation. In 2017, barley was ranked fourth among grains in quantity produced () behind maize, rice and wheat. Etymology The Old English word for barley was ', which traces back to Proto-Indo-European and is cognate to the Latin word ' "flour" (''see corresponding entries''). The direct ancestor of modern English ''barley'' in Old English was the derived adjective ''bærlic'', meaning "of barley". The first citation of the f ...

Tobacco Necrotic Dwarf Virus
Tobacco is the common name of several plants in the genus ''Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco".

Sweet Potato Leaf Speckling Virus
Sweetness is a basic taste most commonly perceived when eating foods rich in sugars. Sweet tastes are generally regarded as pleasurable. In addition to sugars like sucrose, many other chemical compounds are sweet, including aldehydes, ketones, and sugar alcohols. Some are sweet at very low concentrations, allowing their use as non-caloric sugar substitutes. Such non-sugar sweeteners include saccharin and aspartame. Other compounds, such as miraculin, may alter perception of sweetness itself. The perceived intensity of sugars and high-potency sweeteners, such as Aspartame and Neohesperidin Dihydrochalcone, are heritable, with gene effect accounting for approximately 30% of the variation. The chemosensory basis for detecting sweetness, which varies between both individuals and species, has only begun to be understood since the late 20th century. One theoretical model of sweetness is the multipoint attachment theory, which involves multiple binding sites between a sweetness rece ...

Chickpea Stunt Disease Associated Virus
The chickpea or chick pea (''Cicer arietinum'') is an annual legume of the family Fabaceae, subfamily Faboideae. Its different types are variously known as gram" or Bengal gram, garbanzo or garbanzo bean, or Egyptian pea. Chickpea seeds are high in protein. It is one of the earliest cultivated legumes, and 9500-year-old remains have been found in the Middle East. The chickpea is a key ingredient in Mediterranean and Middle Eastern cuisines, used in hummus, and, when ground into flour, falafel. It also is important in Indian cuisine, used in salads, soups and stews, and curry, in chana masala, and in other meal products like channa. In 2019, India was responsible for 70% of global chickpea production. Etymology The name "chickpea," earlier "chiche pease," is modelled on Middle French ', where ''chiche'' comes from Latin '. "Chich" was used by itself in English from the 14th to the 18th centuries.''Oxford English Dictionary'', 3rd edition, December 201''s.v.''/ref> The word ', fro ...

Sobemovirus
''Sobemovirus'' is a genus of viruses. Plants serve as natural hosts. There are 20 species in this genus. Diseases associated with this genus include: mosaics and mottles. Structure Viruses in ''Sobemovirus'' are non-enveloped, with icosahedral geometries, and T=3 symmetry. The diameter is around 30 nm. Genome The genome is a single piece of linear, positive-sense, single-stranded RNA, 4,100–5,700 nucleotides in length.Index of Viruses—Sobemovirus (2006). In: ICTVdB—The Universal Virus Database, version 4. Büchen-Osmond, C (Ed), Columbia University, New York, USA. The genome encodes five open reading frames: ORF1, ORFs 2a and 2b, ORF3 and ORFx. ORF1 encodes P1 which plays a role in suppression of silencing and virus movement. ORFs 2a and 2b encode the replicational polyproteins P2a and P2ab. Translation of ORF2a from the genomic RNA is dependent on a leaky scanning mechanism. ORF3 encodes the coat protein. ORFx is conserved in all sobemoviruses. It overlaps ...

Positive-strand RNA Virus
Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated into viral proteins by the host cell's ribosomes. Positive-strand RNA viruses encode an RNA-dependent RNA polymerase (RdRp) which is used during replication of the genome to synthesize a negative-sense antigenome that is then used as a template to create a new positive-sense viral genome. Positive-strand RNA viruses are divided between the phyla '' Kitrinoviricota'', '' Lenarviricota'', and '' Pisuviricota'' (specifically classes '' Pisoniviricetes'' and '' Stelpavirictes'') all of which are in the kingdom '' Orthornavirae'' and realm ''Riboviria''. They are monophyletic and descended from a common RNA virus ancestor. In the Baltimore classification system, +ssRNA viruses belong to Group IV. Positive-sense RNA viruses include patho ...

Polemovirus
''Polemovirus'' is a genus of viruses. Commercial cultivars of ''Euphorbia pulcherrima'' serve as natural hosts. There is only one species in this genus: ''Poinsettia latent virus''. Its RNA suggests a replication mode like that of poleroviruses, whereas the coat protein sequence is closely related to that of sobemoviruses. Structure Viruses in ''Polemovirus'' are non-enveloped, with icosahedral geometries, and T=3 symmetry. Genomes are linear and non-segmented. Life cycle Viral replication is cytoplasmic, and is lysogenic Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction (the lytic cycle being the other). Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circul ....
