Satellite Tobacco Mosaic Virus : Icosahedral Capsid and RNA Structure By

Vascular phloem loading has long been recognized as an essential step in the establishment of a systemic virus infection. Yet little is known about this process and the mechanisms that control it. In this study, an interaction between the replication protein of Tobacco mosaic virus (TMV) and phloem specific auxin/indole acetic acid (Aux/IAA) transcriptional regulators was found to modulate virus phloem loading. Promoter expression studies show TMV 126/183 kDa interacting Aux/IAAs predominantly express and accumulate within the nuclei of phloem companion cells (CC). Furthermore, CC Aux/IAA nuclear localization is disrupted upon infection with an interacting virus but not during infection with a non-interacting virus. In situ analysis of virus spread shows the inability of TMV variants to disrupt Aux/IAA CC nuclear localization correlates with a reduced ability to load into the vascular tissue. Subsequent systemic movement assays also demonstrate that a virus capable of disrupting Aux/IAA ...

In 1898, Martinus W. Beijerinck, of the Netherlands, put forth his concepts that TMV was small and infectious. Furthermore, he showed that TMV could not be cultured, except in living, growing plants. This report, suggesting that microbes need not be cellular, was to forever change the definition of pathogens. In 1946, Wendall Stanley was awarded the Nobel Prize for his isolation of TMV crystals, which he incorrectly suggested were composed entirely of protein. Research by F.C. Bawden and N. Pirie, in England, during the same period correctly demonstrated that TMV was actually a ribonucleoprotein, composed of RNA and a coat protein. By the mid-1950s, scientists in Germany and the United States proved that the RNA alone was infectious. This discovery ushered in the modern era of molecular virology. TMV is known for several firsts in virology, including the first virus to be shown to consist of RNA and protein, the first virus characterized by X-ray crystallography to show a helical structure ...

Unlike some of the other common viruses of ornamentals, TMV is not vectored by insects. The virus can be spread by sap, through vegetative plant production and through mechanical means. Smoking should not be permitted in production areas because tobacco products can carry TMV. Fungicides are not helpful in controlling plant diseases. Once plants are infected with a virus, they can not be treated to eradicate the virus. Infected plants should be removed and destroyed. Identifying infected plants can sometimes be challenging. MSUs Diagnostic Services lab can test samples for TMV with ELISA testing. Samples should be submitted with next day delivery and should not be mailed on a Friday. Overnight delivery is recommended because several samples mailed recently with slower delivery options were frozen when they arrived at the lab..

Many infectious diseases are caused by viruses - very small biological particles. They are far too small to be visible under a microscope and could only be identified with the help of the symptoms they cause. Wendell Stanley studied the tobacco mosaic virus, which attacks the leaves of tobacco plants. From considerable quantities of infected tobacco leaves, he succeeded in extracting the virus in the form of pure crystals in 1935. Through further research, Wendell Stanley was able to show that the tobacco mosaic virus is composed of protein and ribonucleic acid, or RNA.. ...

My research is aimed at understanding macromolecular structure-function relationships in a variety of biological systems. We incorporate experimental data from collaborations and from the literature into the development of structural and dynamic models. Current areas of interest include:. Virus Structure and Assembly: Understanding how small, icosahedral RNA and DNA viruses assemble should lead to new approaches for the design of antiviral drugs.. My group published a detailed model for satellite tobacco mosaic virus (STMV), using a previously proposed secondary structure model for the genomic RNA. This was the first all-atom model for any virus and represented a significant technical advance. We are now applying those methods to hepatitis B virus (HBV), an extremely important human pathogen. My lab is carrying out experiments to determine the secondary structure of the HBV pregenomic RNA, and we are collaborating with Adam Zlotnick (University of Indiana) in the development of both ...

Viruses, the cause of many diseases, are the smallest natural organisms known. They are extremely primitive and parasitic such that biologists refer to them as particles, rather than organisms. Viruses contain in a protein shell, the capsid, their own building plan, the genome, in the form of DNA or RNA. Viruses hijack a biological cell and make it produce from one virus many new ones. Viruses have evolved elaborate mechanisms to infect host cells, to to produce and assemble their own components, and to leave the host cell when it bursts from viral overcrowding. Because of their simplicity and small size, computational biologists selected a virus for their first attempt to reverse-engineer in a computer program, NAMD, an entire life form, choosing one of the tiniest viruses for this purpose, the satellite tobacco mosaic virus. As described in a recent report, the researchers simulated the virus in a small drop of salt water, altogether involving over a million atoms. This provided an ...

Viruses consist of a genome and a capsid; and some viruses are enveloped. Most virus capsids measure between 20-500 nm in diameter. Because of their nanometer size dimensions, viruses have been considered as naturally occurring nanoparticles. Virus nanoparticles have been subject to the nanoscience and nanoengineering disciplines. Viruses can be regarded as prefabricated nanoparticles. Many different viruses have been studies for various applications in nanotechnology: for example, mammalian viruses are being developed as vectors for gene delivery, and bacteriophages and plant viruses have been used in drug delivery and imaging applications as well as in vaccines and immunotherapy intervention. Plant viruses come in many shapes and sizes: for example, the plant virus Tobacco mosaic virus (TMV) measures 300x18 nm in size; it forms a hollow rod. The plant virus Potato virus X (PVX) forms flexible filaments of 515x13 nm. The following viruses have an icosahedral symmetry and measure between 25-30 ...

A tobacco mosaic virus (TMV)-based vector was utilized for expression of a cytosolic form of the bovine herpesvirus type 1 (BHV-1) protein glycoprotein D (gDc). Nicotiana benthamiana plants were harvested 7 days after inoculation with RNA transcripts derived from the TMV-gDc recombinant virus. Recombinant gDc protein of expected electrophoretic mobility accumulated in inoculated leaves to a concentration of about 20 μg/g of fresh leaf tissue. Oil-based vaccines were formulated with crude foliar extracts to immunize mice parentally. After a single injection, animals developed a sustained and specific response to both the isolated gD and native virus particles. Cattle vaccinated with the same gDc containing extracts developed specific humoral and cellular immune responses directed against both the viral gD and BHV-1 particles. Most importantly, animals vaccinated with the plant-produced gDc showed good levels of protection after challenge with the virulent BHV-1. Virus excretion was drastically reduced

Symptoms on plants infected with cucumoviruses can vary. Generally, plants appear lighter in color and are bushy and stunted. Close up symptoms include a mosaic (alternating light and dark green areas) on at least some leaves, especially on the younger leaves. Leaves may exhibit a shoestringlike appearance. Fruit production is greatly reduced. These symptoms can be confused with those caused by tobacco mosaic virus. ...

One of the worlds most destructive naturally-occuring scourges, the Tobacco mosaic virus (or TMV) could be used in a near future to boost the capacity of Lithium Ion batteries by 10 times and even power Flash memory.

Viral assemblies have attracted substantial attention as templates for materials synthesis due to their precisely controlled dimensions, chemical functionalities and the ability to confer additional modalities through genetic modification. At the nanobiofabrication group of Tufts University, we exploit several unique properties of tobacco mosaic virus (TMV) for facile synthesis of catalytically active palladium (Pd) nanoparticles and fabrication of high capacity biosensing platforms. In the nanocatalysis area, we have examined and demonstrated size-controlled synthesis, high thermal stability and the TMV templates fundamental role in the Pd nanoparticle formation via small angle X-ray scattering (SAXS). We then employed two Pd-catalyzed model reactions, dichromate reduction for environmental cleanup and Suzuki coupling reaction for efficient chemical synthesis, in order to investigate the catalytic activity, stability, and reaction mechanisms. The results show that TMV-templated Pd nanoparticle ...

Plant viral vectors enable the expression of proteins at high levels in a relatively short time. For many purposes (e.g., cell biological interaction studies) it may be desirable to express more than one protein in a single cell but that is often not feasible when using a single virus vector. Such a co-expression strategy requires the simultaneous delivery by two compatible and non-competitive viruses that can co-exist to each express a separate protein. Here, we report on the use of two agro-launchable coat-protein gene substitution GFP-expressing virus vector systems based on Tomato bushy stunt virus (TBSV) referred to as TG, and Tobacco mosaic virus (TMV) annotated as TRBO-G ...

Louis Pasteur was unable to find a causative agent for rabies and speculated about a pathogen too small to be detected using a microscope.[21] In 1884, the French microbiologist Charles Chamberland invented a filter (known today as the Chamberland filter or the Pasteur-Chamberland filter) with pores smaller than bacteria. Thus, he could pass a solution containing bacteria through the filter and completely remove them from the solution.[22] In 1892, the Russian biologist Dmitri Ivanovsky used this filter to study what is now known as the tobacco mosaic virus. His experiments showed that crushed leaf extracts from infected tobacco plants remain infectious after filtration. Ivanovsky suggested the infection might be caused by a toxin produced by bacteria, but did not pursue the idea.[23] At the time it was thought that all infectious agents could be retained by filters and grown on a nutrient medium - this was part of the germ theory of disease.[2] In 1898, the Dutch microbiologist Martinus ...

Tomato Country Taste (Lycopersicon esculentum) is a variety that produces very large (approx. 200 g) fruit with an extremely tasty and juicy taste. The shape of tomato is slightly ribbed, and the skin intensely red. Fruits are firm and hard, even when ripe, they cut well and are stable in taste. It is a hybrid hybrid variety F1 producing homogeneous fruit with exceptional taste qualities. The Country Taste tomato variety is resistant to diseases and viruses, including tobacco mosaic virus, vericillosis and fusariosis.. The Country Taste tomato requires a good warm and fertile soil rich in nutrients. The land must be permeable and well aerated. Like any tomato, it requires a sunny, warm and windless place.

Although we have what seems like a long growing season here in the Valley of the Sun, the truth is that tomatoes wont produce well in the summer heat. So, timing is everything in terms of growing them. We suggest planting tomatoes in February for harvest in May or planting in late September for harvest in December. Larger types of tomatoes require more time for ripening, so its best to plant the small and medium-sized varieties in our desert gardens. Look for tomatoes labeled for 60- to 70-day maturity. Successful varieties include: Yellow Pear, Cherry, Sweet 100, Earlypak, Earlygirl, Small Fry, Patio, Champion, Earliana, and Sunripe. When looking for resistant varieties, the letters VNFT indicate a plants resistance to Verticillium Wilt (V), Nematodes (N), Fusarium Wilt (F), and Tobacco Mosaic Virus (F).

A method was developed for the purpose of determining the size and shape of anisometric colloidal particles and flexible macromolecules. The experimental technique used for this determination is the measurement of the change in the intensity of the light scattered by anisometric colloidal particles (or macromolecules) when oriented (or deformed) by a velocity gradient. Improvements in the system will extend the present range of measurements to rigid colloidal particles whose longest dimension is less than 300 mu and to high molecular weight polymers. The apparatus has been successfully tested with suspensions of tobacco mosaic virus and the experimental results have been compared with the theory of Okano and Wada (J. Chem. Phys., 34: 405, 1961) for thin rod-like particles. Preliminary observations made with flexible macromolecules indicate that the effect of deformability of high molecular weight polymers, subjected to a velocity gradient, is quite small under the conditions of this study, as predicted

N2 - The movement protein of cucumber mosaic virus (CMV) is required for cell-to-cell movement of viral RNA. The movement of viral RNA occurs through the plant intercellular connection, the plasmodesmata. The viral movement protein was known to be multifunctional. In this work, a series of deletion mutants of CMV movement protein gene were created to identify the functional domains. The mutated movement proteins were produced as inclusion body in E. coli, and purified and renatured. A polyclonal antibody was raised against the CMV-Kor strain (Korean isolate) movement protein expressed in E. coli. The ability of the truncated proteins to bind to ssRNA was assayed by UV cross-linking and gel retardation analyses. The results indicate that the domain between amino acids 118 and 160 of CMV movement protein is essential for ...

The Cucumber mosaic virus (CMV)-encoded 2b protein (Cmv2b) is a nuclear protein that suppresses transgene RNA silencing in Nicotiana benthamiana. Cmv2b is an important virulence determinant but nonessential for systemic spread in N. glutinosa, in contrast to its indispensable role for systemic infections in cucumber. Here, we report that Cmv2b became essential for systemic infections in older N. glutinosa plants or in young seedlings pre-treated with salicylic acid (SA). Expression of Cmv2b from the genome of either CMV or Tobacco mosaic virus significantly reduced the inhibitory effect of SA on virus accumulation in inoculated leaves and systemic leaves. A close correlation is demonstrated between Cmv2b expression and a reduced SA-dependent induction of the alternative oxidase gene, a component of the recently proposed SA-regulated antiviral defense. These results collectively reveal a novel activity of Cmv2b in the inhibition of SA-mediated virus resistance. We used a N. tabacum line ...

Being aware of the different types of Mosaic Viruses can help to keep your plants thriving and virus-free. Plant has 2 leaves, big leaf was the original propagation leaf,small leaf has just emerged showing good variegation. Unfortunately, some of these signs can be due to many other factors such as insufficient watering, high humidity or too much sunlight. We have included some of the most commonly asked questions in regards to this infection that will hopefully answer any further concerns you may have. Interestingly the virus can also be latent in plants meaning that you cannot see any symptoms yet but the plant is already a host and is affected. As it quickly spreads to other plants you can see whole deliveries in gardening centres and plant shops infected with the virus. Once mosaic virus shows up on your plant, its almost certainly a goner. Philodendron Pink Princess #1 Best Care Hacks, Root Rot Causes & Symptoms in Plants you Wish you Knew.

Watson and Crick proposed that plant viruses consistently took one of two shapes because the two chemical components of which they were made up, ribonucleic acid surrounded by a large number of identical protein subunits, were assembled according to a general plan that was determined by symmetry elements. Renewing their collaboration during Watsons return to the Cavendish laboratory in the fall of 1955, Watson and Crick in this article laid out a theory for explaining why all plant viruses whose structure had been studied up to that time were very similar in shape, either rod-shaped (cylindrical) or spherical. In developing their theory they once again benefited from their complementary expertise, namely Cricks extensive knowledge of X-ray crystallography and Watsons previous studies with tobacco mosaic virus and ribonucleic acid. They proposed that plant viruses consistently took one of two shapes because the two chemical components of which they were made up, ribonucleic acid surrounded by a
