A conserved hairpin structure in Alfamovirus and Bromovirus subgenomic promoters is required for efficient RNA synthesis in vitro. (1/3)

The coat protein gene in RNA 3 of alfalfa mosaic virus (AMV; genus Alfamovirus, family Bromoviridae) is translated from the subgenomic RNA 4. Analysis of the subgenomic promoter (sgp) in minus-strand RNA 3 showed that a sequence of 37 nt upstream of the RNA 4 start site (nt +1) was sufficient for full sgp activity in an in vitro assay with the purified viral RNA-dependent RNA-polymerase (RdRp). The sequence of nt -6 to -29 could be folded into a potential hairpin structure with a loop represented by nt -16, -17, and -18, and a bulge involving nt -23. By introducing mutations that disrupted base pairing and compensatory mutations that restored base pairing, it was shown that base pairing in the top half of the putative stem (between the loop and bulge) was essential for sgp activity, whereas base pairing in the bottom half of the stem was less stringently required. Deletion of the bulged residue A-23 or mutation of this residue into a C strongly reduced sgp activity, but mutation of A-23 into U or G had little effect on sgp activity. Mutation of loop residues A-16 and A-17 affected sgp activity, whereas mutation of U-18 did not. Using RNA templates corresponding to the sgp of brome mosaic virus (BMV; genus Bromovirus, family Bromoviridae) and purified BMV RdRp, evidence was obtained indicating that also in BMV RNA a triloop hairpin structure is required for sgp activity.  (+info)

Antigens produced in plants by infection with chimeric plant viruses immunize against rabies virus and HIV-1. (2/3)

The coat protein (CP) of alfalfa mosaic virus was used as a carrier molecule to express antigenic peptides from rabies virus and HIV. The antigens were separately cloned into the reading frame of alfalfa mosaic virus CP and placed under the control of the subgenomic promoter of tobacco mosaic virus CP in the 30BRz vector. The in vitro transcripts of recombinant virus with sequences encoding the antigenic peptides were synthesized from DNA constructs and used to inoculate tobacco plants. The plant-produced protein (virus particles) was purified and used for immunization of mice. Both antigens elicited specific virus-neutralizing antibodies in immunized mice.  (+info)

Tubule-forming capacity of the movement proteins of alfalfa mosaic virus and brome mosaic virus. (3/3)

The structural phenotype of the movement proteins (MPs) of two representatives of the Bromoviridae, alfalfa mosaic virus (AMV) and brome mosaic virus (BMV), was studied in protoplasts. Immunofluorescence microscopy showed that the MPs of these viruses, for which there has been no evidence of a tubule-guided mechanism, assemble into long tubular structures at the surface of the infected protoplast. Electron microscopy and immunogold analysis confirmed the presence of both MP and virus particles in the tubules induced by AMV and BMV. The significance of the tubule-forming properties of these viral MPs is discussed.  (+info)

Alfamovirus is a genus of viruses in the family Bromoviridae, order Bunyavirales. These viruses are primarily infectors of plants and are transmitted by aphids in a non-persistent manner. The genus contains around 26 species, including important plant pathogens such as Alfalfa mosaic virus (AMV) and Cucumber mosaic virus (CMV).

The genome of alfamoviruses is composed of three positive-sense single-stranded RNA segments, each encoding a single protein. The three genomic segments are named RNA1, RNA2, and RNA3. RNA1 encodes the replicase protein, RNA2 encodes the movement protein, and RNA3 encodes the coat protein and a subgenomic RNA that encodes the viral membrane protein.

Alfamoviruses are important pathogens in agriculture, causing significant economic losses in various crops worldwide. They can cause a range of symptoms in infected plants, including mosaic patterns on leaves, stunting, and reduced yield. Control measures for alfamovirus infections include the use of resistant plant varieties, cultural practices, and chemical control of aphid vectors.

Alfalfa mosaic virus (AMV) is a plant-infecting virus that belongs to the family Bromoviridae and the genus Alfamovirus. It has a tripartite, single-stranded, positive-sense RNA genome. The virus is transmitted by various mechanical means, including sap transfer, as well as through seed and vegetative propagation. Insects such as aphids can also transmit the virus in a nonpersistent manner.

AMV infects a wide range of plant species, including many important agricultural crops like alfalfa, tobacco, tomatoes, beans, beets, and various ornamental plants. The virus causes a mosaic pattern of light and dark green areas on the leaves, along with other symptoms such as leaf curl, stunting, and reduced yield. There are no known treatments to cure infected plants, and control measures typically focus on preventing the spread of the virus through the use of disease-free seed and planting material, as well as controlling insect vectors.

Mosaic viruses are a group of plant viruses that can cause mottled or mosaic patterns of discoloration on leaves, which is why they're named as such. These viruses infect a wide range of plants, including important crops like tobacco, tomatoes, and cucumbers. The infection can lead to various symptoms such as stunted growth, leaf deformation, reduced yield, or even plant death.

Mosaic viruses are typically spread by insects, such as aphids, that feed on the sap of infected plants and then transmit the virus to healthy plants. They can also be spread through contaminated seeds, tools, or contact with infected plant material. Once inside a plant, these viruses hijack the plant's cellular machinery to replicate themselves, causing damage to the host plant in the process.

It is important to note that mosaic viruses are not related to human or animal health; they only affect plants.

'Medicago sativa' is the scientific name for a plant species more commonly known as alfalfa. In a medical context, alfalfa is often considered a herbal supplement and its medicinal properties include being a source of vitamins, minerals, and antioxidants. It has been used in traditional medicine to treat a variety of conditions such as kidney problems, asthma, arthritis, and high cholesterol levels. However, it's important to note that the effectiveness of alfalfa for these uses is not conclusively established by scientific research and its use may have potential risks or interactions with certain medications. Always consult a healthcare provider before starting any new supplement regimen.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

I'm sorry for any confusion, but "peas" is not a term typically used in medical definitions. Peas are a type of legume that is commonly consumed as a vegetable. They are rich in nutrients such as protein, fiber, vitamin C, and vitamin K. If you have any questions about the health benefits or potential risks of consuming peas, I would be happy to try to help with that.

"Solanum tuberosum" is the scientific name for a plant species that is commonly known as the potato. According to medical and botanical definitions, Solanum tuberosum refers to the starchy, edible tubers that grow underground from this plant. Potatoes are native to the Andes region of South America and are now grown worldwide. They are an important food source for many people and are used in a variety of culinary applications.

Potatoes contain several essential nutrients, including carbohydrates, fiber, protein, vitamin C, and some B vitamins. However, they can also be high in calories, especially when prepared with added fats like butter or oil. Additionally, potatoes are often consumed in forms that are less healthy, such as French fries and potato chips, which can contribute to weight gain and other health problems if consumed excessively.

In a medical context, potatoes may also be discussed in relation to food allergies or intolerances. While uncommon, some people may have adverse reactions to potatoes, including skin rashes, digestive symptoms, or difficulty breathing. These reactions are typically caused by an immune response to proteins found in the potato plant, rather than the tubers themselves.

Tobacco is not a medical term, but it refers to the leaves of the plant Nicotiana tabacum that are dried and fermented before being used in a variety of ways. Medically speaking, tobacco is often referred to in the context of its health effects. According to the World Health Organization (WHO), "tobacco" can also refer to any product prepared from the leaf of the tobacco plant for smoking, sucking, chewing or snuffing.

Tobacco use is a major risk factor for a number of diseases, including cancer, heart disease, stroke, lung disease, and various other medical conditions. The smoke produced by burning tobacco contains thousands of chemicals, many of which are toxic and can cause serious health problems. Nicotine, one of the primary active constituents in tobacco, is highly addictive and can lead to dependence.
