Citrus Gummy Bark Viroid
The citrus gummy bark viroid (abbreviated CGBVd) is a strain of ''Hop stunt viroid'', and thus is a member of the genus ''Hostuviroid''. As the name suggests, the citrus gummy bark viroid causes problems in the bark of the sweet orange tree. Scraping the bark exposes localized spots or a line of reddish-brown, gum-impregnated tissue around the scion Scion may refer to: Arts, entertainment, and media Fictional entities *Scion, a playable class in the game ''Path of Exile'' (2013) *Atlantean Scion, a device in the ''Tomb Raider'' video game series *Scions, an alien race in the video game ''Ba ... circumference especially visible near the bud union. The discoloration and gumming may extend above the bud union to the main branches of the sweet orange while in severe infection dark streaks of gum-impregnated tissue may also be observed in longitudinal sections.

Grapevine Yellow Speckle Viroid 2
''Vitis'' (grapevine) is a genus of 79 accepted species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture. Most cultivated ''Vitis'' varieties are wind-pollinated with hermaphroditic flowers containing both male and female reproductive structures, while wild species are dieceous. These flowers are grouped in bunches called inflorescences. In many species, such as ''Vitis vinifera'', each successfully pollinated flower becomes a grape berry with the inflorescence turning into a cluster of grapes. While the flowers of the grapevines are usually very small, the berries are often large and brightly colored with sweet flavors that attract birds and other animals to disperse the seeds contained within the berrie ...

Pospiviroidae
The Pospiviroidae are a family of viroids, including the first viroid to be discovered, PSTVd. Their secondary structure is key to their biological activity. The classification of this family is based on differences in the conserved central region sequence. The genome consists (in this order) of an LH terminal domain, a pathogenic domain, conserved central region ( pospiviroid RY motif stem loop), variable domain, and an RH terminal domain. ''Pospiviroidae'' replication occurs in an asymmetric fashion via host cell RNA polymerase, RNase, and RNA ligase. Taxonomy The family contains the following genera: * ''Apscaviroid'' * '' Cocadviroid'' * '' Coleviroid'' * ''Hostuviroid'' * ''Pospiviroid ''Pospiviroid'' is a genus of viroid Viroids are small single-stranded, circular RNAs that are infectious pathogens.

Hops
Hops are the flowers (also called seed cones or strobiles) of the hop plant ''Humulus lupulus'', a member of the Cannabaceae family of flowering plants. They are used primarily as a bittering, flavouring, and stability agent in beer, to which, in addition to bitterness, they impart floral, fruity, or citrus flavours and aromas. Hops are also used for various purposes in other beverages and herbal medicine. The hops plants have separate female and male plants, and only female plants are used for commercial production. The hop plant is a vigorous, climbing, herbaceous perennial, usually trained to grow up strings in a field called a hopfield, hop garden (in the South of England), or hop yard (in the West Country and United States) when grown commercially. Many different varieties of hops are grown by farmers around the world, with different types used for particular styles of beer. The first documented use of hops in beer is from the 9th century, though Hildegard of Bingen, 30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viroid
Viroids are small single-stranded, circular RNAs that are infectious pathogens. Unlike viruses, they have no protein coating. All known viroids are inhabitants of angiosperms (flowering plants), and most cause diseases, whose respective economic importance to humans varies widely. The first discoveries of viroids in the 1970s triggered the historically third major extension of the biosphere—to include smaller lifelike entities —after the discoveries in 1675 by Antonie van Leeuwenhoek (of the "subvisible" microorganisms) and in 1892–1898 by Dmitri Iosifovich Ivanovsky and Martinus Beijerinck (of the "submicroscopic" viruses). The unique properties of viroids have been recognized by the International Committee on Taxonomy of Viruses, in creating a new order of subviral agents. The first recognized viroid, the pathogenic agent of the potato spindle tuber disease, was discovered, initially molecularly characterized, and named by Theodor Otto Diener, plant pathologist a ...

Plum Dapple Viroid
A plum is a fruit of some species in ''Prunus'' subg. ''Prunus''''.'' Dried plums are called prunes. History Plums may have been one of the first fruits domesticated by humans. Three of the most abundantly cultivated species are not found in the wild, only around human settlements: ''Prunus domestica'' has been traced to East European and Caucasian mountains, while ''Prunus salicina'' and '' Prunus simonii'' originated in China. Plum remains have been found in Neolithic age archaeological sites along with olives, grapes and figs. According to Ken Albala, plums originated in Iran. They were brought to Britain from Asia. An article on plum tree cultivation in Andalusia (southern Spain) appears in Ibn al-'Awwam's 12th-century agricultural work, ''Book on Agriculture''. Etymology and names The name plum derived from Old English ''plume'' "plum, plum tree", borrowed from Germanic or Middle Dutch, derived from Latin ' and ultimately from Ancient Greek ''proumnon'', itself belie ...
