Cherry Mottle Leaf Virus
Cherry mottle leaf virus (CMLV) is a plant pathogenic virus causing leaf rot. It is closely related to the peach mosaic virus. Host and Symptoms Cherry mottle leaf virus (CMLV) has a wide range of hosts. It infects the genus Prunus including cherry (''Prunus avium'') and peach (''P. persica'') trees. More specifically, CMLV infects both sweet and bitter/wild type (''P. emarginata'') cherry trees.Reeves, E. L. (n.d.). MOTTLE LEAF, A VIRUS DISEASE OF CHERRIES ’. 18.

Pathogenic Virus
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infection, infectious virus particles (virions) attach to and enter susceptible cells. Structural Characteristics Basic structural characteristics, such as genome type, virion shape and replication site, generally share the same features among virus species within the same family. * Double-stranded DNA families: three are non-enveloped (''Adenoviridae'', ''Papillomaviridae'' and ''Polyomaviridae'') and two are enveloped (''Herpesviridae'' and ''Poxviridae''). All of the non-enveloped families have icosahedral capsids. * Partly double-stranded DNA viruses: ''Hepadnaviridae''. These viruses are enveloped. * One family of single-stranded DNA viruses infects humans: ''Parvoviridae''. These viruses are non-enveloped. * Positive single-stranded RNA families: three non-enveloped (''Astroviridae'', ''Caliciviridae'' and ''Picornaviridae'') and four enveloped (''Coronaviridae'', ''Fla ...

Peach Mosaic Virus
''Trichovirus'' is a genus of viruses in the order ''Tymovirales'', in the family ''Betaflexiviridae''. Plants, specifically angiosperms such as pome fruits, citrus, and pear, serve as natural hosts for this plant pathogen. There are seven species in this genus. Taxonomy The following species are assigned to the genus: *''Apple chlorotic leaf spot virus'' *''Apricot pseudo-chlorotic leaf spot virus'' *''Cherry mottle leaf virus'' *''Grapevine berry inner necrosis virus'' *''Grapevine Pinot gris virus'' *''Peach mosaic virus'' *''Phlomis mottle virus'' Structure Viruses in ''Trichovirus'' are non-enveloped, with flexuous and filamentous geometries. The diameter is around 10-12 nm, with a length of 640-760 nm. Genomes are linear, around 7.5-8.0kb in length. The genome codes for 3 proteins. 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 ...

Cherry
A cherry is the fruit of many plants of the genus ''Prunus'', and is a fleshy drupe (stone fruit). Commercial cherries are obtained from cultivars of several species, such as the sweet ''Prunus avium'' and the sour ''Prunus cerasus''. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus ''Prunus'', as in " ornamental cherry" or "cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although ''Prunus avium'' is often referred to specifically by the name "wild cherry" in the British Isles. Botany True cherries ''Prunus'' subg. ''Cerasus'' contains species that are typically called cherries. They are known as true cherries and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. ''P. serrula''; some species with short racemes, e.g. '' P. ...

Virus
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. ...
