Secoviridae
''Secoviridae'' is a family of viruses in the order ''Picornavirales''. Plants serve as natural hosts. There are 8 genera and 86 species in this family, one of which is unassigned to a genus. The family was created in 2009 with the grouping of families ''Sequiviridae'', now dissolved, and ''Comoviridae'', now subfamily ''Comovirinae'', along with the then unassigned genera ''Cheravirus'', ''Sadwavirus'', and ''Torradovirus''. Taxonomy The family includes the following genera (-''virinae'' denotes subfamily and -''virus'' denotes genus): * ''Comovirinae ''Comovirinae'' is a subfamily of viruses in the order ''Picornavirales'', in the family ''Secoviridae''; its genera were formerly classified in the family ''Comoviridae''.

Cherry Rasp Leaf Virus
''Cherry rasp leaf virus (CRLV)'' is a plant pathogenic virus of the order ''Picornavirales'', family ''Secoviridae'', genus ''Cheravirus''. Causes CRLV can be transmitted by nematode ( Xiphinema Americana), mechanical inoculation, grafting, or seed (10–20%). Symptoms Leaves become studded with projections or enation Enations are scaly leaflike structures, differing from leaves in their lack of vascular tissue. They are created by some leaf diseases and occur normally on ''Psilotum''. Enations are also found on some early plants such as ''Rhynia'', where the ...s between the lateral veins and all along the midrib. As a result, the leaves become deformed and folded, looking very narrow. The face of the leaf has a bumpy texture as a result of the enations on the underside. Initial infections begin at the lower branches and patches of the tree will show symptoms. Lateral (tree-to-tree) infection is slow and fruit production is reduced. Severe infection may result in the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viruses
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.e ...

Picornavirales
''Picornavirales'' is an order of viruses with vertebrate, invertebrate, protist and plant hosts. The name has a dual etymology. First, ''picorna-'' is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid. Secondly, pico-, meaning extremely small, combines with RNA to describe these very small RNA viruses. The order comprises viruses that historically are referred to as picorna-like viruses. Characteristics The families within this order share a number of common features: * The virions are non- enveloped, icosahedral, and about 30 nanometers in diameter. * The capsid has a "pseudo T=3" structure, and is composed of 60 protomers each made of three similar-sized but nonidentical beta barrels. * The genome is made of one or a few single-stranded RNA(s) serving directly as mRNA, without overlapping open reading frames. * The genome has a small protein, VPg, covalently attached to its 5' end, and usually a poly-adenylat ...

Apple Latent Spherical Virus
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more th ...

Arracacha Virus B
Arracacha (''Arracacia xanthorrhiza'') is a root vegetable that originates in the Andes, whose starchy taproot is a popular food item across South America where it is a major commercial crop. Common names Being a South American plant, its most common names are in either Spanish or Portuguese, the two most spoken languages in that continent. The name ''arracacha'' (or ''racacha'') was borrowed into Spanish from Quechua ''raqacha'',Teofilo Laime Ajacopa, Diccionario Bilingüe Iskay simipi yuyayk'ancha, La Paz, 2007 (Quechua-Spanish dictionary) and is used in the Andean region. The plant is also called ''apio'' or ''apio criollo'' (" Creole celery") in Venezuela and Puerto Rico, ''zanahoria blanca'' ("white carrot") in Ecuador, and ''virraca'' in Peru. Its Portuguese names are usually derived from the plant's similarity to other well known vegetables and roots. It is known as either ''mandioquinha'' ("little cassava") or ''batata-baroa'' ("baroness potato") in most regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
