Citrus Leprosis Disease
Citrus leprosis (CL) is an economically important viral disease affecting citrus crops. This emerging disease is widely distributed in South and Central America, from Argentina to Mexico. The disease is associated with up to three different non-systemic viruses, which cause similar symptoms in the citrus hosts and are transmitted by the same vector, mites of the genus ''Brevipalpus''; although they have vastly different genomes. ''Citrus leprosis virus'' nuclear type (CiLV-N) is found in the nuclei and cytoplasm of infected cells, while ''Citrus leprosis virus'' cytoplasmic type (CiLV-C) is found in the endoplasmic reticulum. In 2012, a new virus causing similar symptoms was found in Colombia and it was named ''Citrus leprosis virus'' cytoplasmic type 2 (CiLV-C2) due to its close similarity to CiLV-C. The cytoplasmic type viruses are the most prevalent and widely distributed of the three species. Structure and genome CiLV-N has short, rod-shaped particles, 120 to 130 nanomete ...

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USDA
The United States Department of Agriculture (USDA) is the federal executive department responsible for developing and executing federal laws related to farming, forestry, rural economic development, and food. It aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally. It is headed by the Secretary of Agriculture, who reports directly to the President of the United States and is a member of the president's Cabinet. The current secretary is Tom Vilsack, who has served since February 24, 2021. Approximately 80% of the USDA's $141 billion budget goes to the Food and Nutrition Service (FNS) program. The largest component of the FNS budget is the Supplemental Nutrition Assistance Program (formerly known as the Food Stamp program), which is the cornerstone of USDA's ...

AGRIS
AGRIS (International System for Agricultural Science and Technology) is a global public domain database with more than 12 million structured bibliographical records on agricultural science and technology. It became operational in 1975 and the database was maintained by Coherence in Information for Agricultural Research for Development, and its content is provided by more than 150 participating institutions from 65 countries. The AGRIS Search system, allows scientists, researchers and students to perform sophisticated searches using keywords from the AGROVOC thesaurus, specific journal titles or names of countries, institutions, and authors. Early AGRIS years As information management flourished in the 1970s, the AGRIS metadata corpus was developed to allow its users to have free access to knowledge available in agricultural science and technology. AGRIS was developed to be an international cooperative system to serve both developed and developing countries. With the advent of t ...

Magnolia Press
''Magnolia'' is a large genus of about 210 to 340The number of species in the genus ''Magnolia'' depends on the taxonomic view that one takes up. Recent molecular and morphological research shows that former genera ''Talauma'', ''Dugandiodendron'', ''Manglietia'', ''Michelia'', ''Elmerrillia'', ''Kmeria'', ''Parakmeria'', ''Pachylarnax'' (and a small number of monospecific genera) all belong within the same genus, ''Magnolia'' s.l. (s.l. = ''sensu lato'': 'in a broad sense', as opposed to s.s. = ''sensu stricto'': 'in a narrow sense'). The genus ''Magnolia'' s.s. contains about 120 species. See the section Nomenclature and classification in this article. flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol.

Philippe Park
Philippe Park is a Pinellas County park located in Safety Harbor, Florida. The park is named after Odet Philippe, who is credited with introducing grapefruit to Florida. It is situated on that was once part of Philippe's plantation. Philippe was the county's first non-native settler, arriving in 1842. Philippe is buried in the park but the exact location is undetermined. Half a century later the plantation was still growing citrus, as a nursery for the area extending north to Tarpon Springs. Then, here in 1907 citrus leprosis was first discovered by Fawcett. Google Books CL went on to almost eliminate citrus growing in Florida by 1925. A Tocobaga Indian mound that is situated in the park is a National Historic Landmark known as the Safety Harbor Site. The temple mound is one of the last remnants of the Tocobaga on the Pinellas Peninsula. Records indicate that Pedro Menéndez de Avilés, the founder of St. Augustine, Florida, visited the site in 1566 to help broker a truce betw ...

Transmission Electron Microscopy
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transovarial Transmission
Transovarial or transovarian transmission (transmission from parent to offspring via the ovaries) occurs in certain arthropod vectors as they transmit pathogens from parent to offspring. This process, used by a wide variety of parasites, is also known as vertical transmission. For example, ''Rickettsia rickettsii'', carried within ticks, is passed on from parent to offspring tick by transovarial transmission. This is in contrast to parasites such as ''Rickettsia prowazekii,'' which are not passed on by transovarian transmission due to killing the vector that carries it (in this case, the human louse). Other examples of parasites that use this mechanism of transmission include the aedes mosquito vector of the yellow fever virus and in phlebotomine sandflies that transmit pappataci fever. Richard Dawkins in "The Extended Phenotype" notes that "bacterial endosymbionts of insects which are transmitted transovarially" share an interest in the "success of their host's gametes.....as we ...
