Potato Leafroll Virus
Potato leafroll virus (PLRV) is a member of the genus ''Polerovirus'' and family ''Solemoviridae''. The phloem limited positive sense RNA virus infects potatoes and other members of the family Solanaceae. PLRV was first described by Quanjer ''et al.'' in 1916. PLRV is transmitted by aphids, primarily the green peach aphid, ''Myzus persicae''. PLRV is one of the most important potato viruses worldwide but particularly devastating in countries with limited resources and management. It can be responsible for individual plant yield losses of over 50%. One estimate suggests that PLRV is responsible for an annual global yield loss of 20 million tons. Symptoms include chlorosis, necrosis and leaf curling. Hosts and symptoms PLRV infects members of the family Solanaceae. The most economically important host is the Potato, ''Solanum tuberosum'' spp. In potato, symptoms of primary infection, infection in the growing season, occurs in the youngest leaves. Leaf margins become necrotic, ... [...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 ...

Turnip Yellows Virus
The turnip or white turnip (''Brassica rapa'' subsp. ''rapa'') is a root vegetable commonly grown in temperate climates worldwide for its white, fleshy taproot. The word ''turnip'' is a compound (linguistics), compound of ''turn'' as in turned/rounded on a lathe and ''neep'', derived from Latin ''napus'', the word for the plant. Small, tender varieties are grown for human consumption, while larger varieties are grown as fodder, feed for livestock. In Northern England, Scotland, Ireland, Cornwall and parts of Canada (Quebec, Newfoundland, Manitoba and the Maritimes), the word ''turnip'' (or ''neep'') often refers to rutabaga, also known as ''swede'', a larger, yellow root vegetable in the same genus (''Brassica''). Description The most common type of turnip is mostly white-skinned apart from the upper , which protrude above the ground and are purple or red or greenish where the sun has hit. This above-ground part develops from stem tissue, but is fused with the root. The interi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco Vein Distorting 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".

Sugarcane Yellow Leaf 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 rest is ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumpkin Polerovirus
A pumpkin is a vernacular term for mature winter squash of species and varieties in the genus ''Cucurbita'' that has culinary and cultural significance but no agreed upon botanical or scientific meaning. The term ''pumpkin'' is sometimes used interchangeably with "squash" or "winter squash", and is commonly used for cultivars of ''Cucurbita argyrosperma'', ''Cucurbita ficifolia'', ''Cucurbita maxima'', ''Cucurbita moschata'', and ''Cucurbita pepo''. Native to North America (northeastern Mexico and the southern United States), ''C. pepo'' pumpkins are one of the oldest domesticated plants, having been used as early as 7,000 to 5,500 BC. Today, pumpkins of varied species are widely grown for food, as well as for aesthetic and recreational purposes. The pumpkin's thick shell contains edible seeds and pulp. Pumpkin pie, for instance, is a traditional part of Thanksgiving meals in Canada and the United States, and pumpkins are frequently carved as jack-o'-lanterns for decoration a ...
