Abaca Mosaic Virus
''Sugarcane mosaic virus'' (SCMV) is a plant pathogenic virus of the family ''Potyviridae''. The virus was first noticed in Puerto Rico in 1916 and spread rapidly throughout the southern United States in the early 1920s. SCMV is of great concern because of the high economic impact it has on sugarcane and maize. Hosts Sugarcane mosaic virus causes mosaic symptoms in sugarcane, maize, sorghum, and other poaceous plants. In sugarcane, this is the most widespread virus and 21 strains of it have been found in the United States. The SCMV complex has been shown to consist of four distinct potyviruses and includes strains of '' Johnsongrass mosaic virus'' (JGMV), ''maize dwarf mosaic virus'' (MDMV), '' sorghum mosaic virus'' (SrMV), and SCMV. CABI ISCbr>19952304874 Vectors The aphid ''Myzus persicae'' was first found to vector SCMV from sorghum to sorghum by Anzalone 1962. Symptoms Symptoms of sugarcane mosaic virus include intense mottling throughout the laminar region of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horticulture
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes.

Ecological Effects Of Transgenic Plants
Genetically modified food controversies are disputes over the use of foods and other goods derived from genetically modified crops instead of conventional crops, and other uses of genetic engineering in food production. The disputes involve consumers, farmers, biotechnology companies, governmental regulators, non-governmental organizations, and scientists. The key areas of controversy related to genetically modified food (GM food or GMO food) are whether such food should be labeled, the role of government regulators, the objectivity of scientific research and publication, the effect of genetically modified crops on health and the environment, the effect on pesticide resistance, the impact of such crops for farmers, and the role of the crops in feeding the world population. In addition, products derived from GMO organisms play a role in the production of ethanol fuels and pharmaceuticals. Specific concerns include mixing of genetically modified and non-genetically modified p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetically Modified Plant
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of ''Agrobacterium'' for the delivery of sequences hosted in T-DNA binary vectors. Many plant cells are pluripotent, meaning that a single cell from a mature plant can be harvested and then under the right conditions form a new plant. This ability can be taken advantage of by genetic engineers; by selecting for cells that have been successfully transformed in an adult plant a new plant can then be grown that contains the transgene in every cell through a process known as tissue culture. Research Much of the advances in the field genetic engineering has come from experimentation with tobacco. Major advances in tissue culture and plant cellular mechanisms for a wide range of plants has originated from systems developed in tobacco. It was the first plant to be geneti ...

Next-generation Sequencing
Massive parallel sequencing or massively parallel sequencing is any of several high-throughput approaches to DNA sequencing using the concept of massively parallel processing; it is also called next-generation sequencing (NGS) or second-generation sequencing. Some of these technologies emerged between 1994 and 1998 and have been commercially available since 2005. These technologies use miniaturized and parallelized platforms for sequencing of 1 million to 43 billion short reads (50 to 400 bases each) per instrument run. Many NGS platforms differ in engineering configurations and sequencing chemistry. They share the technical paradigm of massive parallel sequencing via spatially separated, clonally amplified DNA templates or single DNA molecules in a flow cell. This design is very different from that of Sanger sequencing—also known as capillary sequencing or first-generation sequencing—which is based on electrophoretic separation of chain-termination products produced in indi ...

Annual Review Of Entomology
The ''Annual Review of Entomology'' is a peer-reviewed academic journal that publishes review articles about entomology, the study of insects. First published in 1956 from a collaboration between the Entomological Society of America and Annual Reviews, its longest-serving editors are Thomas E. Mittler (1967–1997) and May Berenbaum (1998–2018). As of 2022, it has a 2021 impact factor of 22.682. History In 1953, a committee within the Entomological Society of America examined the volume of literature published each year in the field and recommended that a journal be established that published review articles. The Entomological Society approached the nonprofit publisher Annual Reviews, which also agreed that there was a need for a review series in entomology. The ''Annual Review of Entomology'' published its first volume in 1956, making it the tenth title published by Annual Reviews. At first, the ESA remained involved with the operation of the journal and confirmed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myzus Persicae
''Myzus persicae'', known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops. Originally described by Swiss entomologist Johann Heinrich Sulzer in 1776, its specific name is derived from the Latin genitive ''persicae,'' "of the peach". The syntype specimen of this species is located in the Illinois Natural History Survey Insect Collection. Life cycle Life cycle of the green peach aphid varies depending on temperature. A fully completed generation takes approximately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallingford, Oxfordshire
Wallingford () is a historic market town and civil parish located between Oxford and Reading on the River Thames in England. Although belonging to the historic county of Berkshire, it is within the ceremonial county of Oxfordshire for administrative purposes (since 1974) as a result of the 1972 Local Government Act. Wallingford is north of Reading, south of Oxford and north west of Henley-on-Thames. The town's population was 11,600 in the 2011 census. The town has played an important role in English history starting with the surrender of Stigand to William the Conqueror in 1066, which led to his taking the throne and the creation of Wallingford Castle. The castle and the town enjoyed royal status and flourished for much of the Middle Ages. The Treaty of Wallingford, which ended a civil war known as The Anarchy between King Stephen and Empress Matilda, was signed there. The town then entered a period of decline after the arrival of the Black Death and falling out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
