Controlling Tobacco Mosaic Virus in Tobacco through Resistance
Tobacco mosaic virus (TMV) infects all classes of tobacco (Nicotiana tabacum L.) and causes losses worldwide. The N gene is the most effective means of controlling TMV; however, this gene is associated with reduced yield and quality in flue-cured tobacco. The mode of inheritance of TMV resistance …

Immunochemical studies with tryptic peptides of tobacco mosaic virus protein
… antigenic determinants of the protein subunit of tobacco mosaic virus CTMV) have been studied by inhibition of complement fixation, inhibition of micro-precipitin and direct binding experiments. The viral subunit has been found to possess six antigenic determinants. Two of these, situated in …

The Inheritance of Resistance to Tobacco Mosaic Virus in Tobacco Introductions
Thirty-one tobacco introductions that were reported to display either a local lesion or a symptomless reaction to infection with tobacco mosaic virus (TMV) were screened for reaction to the virus (Chaplin and Gooding, 1969). Ten tobacco introductions (TI), TI 203, TI 407, TI 438, TI 450, TI 692, TI …

Initiation of translation of the small RNA of the cowpea strain of tobacco mosaic virus
Several features of the initiation of translation of CcTMV-SRNA were investigated. First, the site of initiation of translation was found to be the first AUG in the 5$\sp\prime$-terminal sequence m$\sp7$GpppGUAUUUGAUGAUGGCA ... despite the fact that this AUG codon is not found within a favorable …

The binding of divalent cations to tobacco mosaic virus and to some isometric plant viruses
… calcium and magnesium) to strains of tobacco mosaic virus (TMV) and their isolated proteins was investigated, using equilibrium dialysis and potentiometric titration, in an attempt to elucidate the role of divalent cations in virus stabilisation. It was found that dissociation of bound …

Quantitative analysis of individual flue-cured tobacco seed tissues reveals Tobacco mosaic virus infection in embryos
Tobacco mosaic virus (TMV) is an extensively studied RNA virus that reduces quality and yield in commercially grown tobacco (Nicotiana tabacum L.). The virus is transmitted mechanically, although infections have been associated with contaminated seeds with the seed coat being the source of virus. …

Tracking Tobacco Mosaic Virus Infection from Infected Seeds to Seedlings Confirms Seed Transmission in Tobacco (Nicotiana tabacum L.)
The Tobacco mosaic virus (TMV) is a positive sense single stranded RNA virus and is found across the world. TMV can impact the overall yield and quality of the crop resulting in an economic loss. Plants that are infected with TMV show a variety of symptoms such as mosaic pattern, mottling, necrotic …

Influence of Seed Treatment on Tobacco Mosaic Virus Incidence in Tobacco Seedlings and Virus Distribution in Greenhouse Transplant Production
Tobacco mosaic virus (TMV) is an economically important pathogen that has been studied for over one hundred years. Seedlings, seed coats, and nutrient solution were assayed for the presence of the virus and seed treatments were tested on seeds. Double antibody sandwich enzyme-linked immunosorbent …

FUNCTIONAL ANALYSIS OF THE UPSTREAM PSEUDOKNOT DOMAIN AND ITS SUBSTITUTION WITH A POLY(A) TRACT IN TOBACCO MOSAIC VIRUS (TMV)
THE UPSTREAM PSEUDOKNOT DOMAIN (UPD) OF TOBACCO MOSAIC VIRUS (TMV) GENOME PLAYS AN IMPORTANT ROLE DURING VIRUS REPLICATION AND TRANSLATION. THE FUNCTIONS OF UPD WERE ANALYZED USING A SUBSTITUTED MUTANT TMV-43A IN WHICH AN INTRODUCED 43 NT POLY(A) TRACT REPLACED THE UPD IN TMV GENOME. TMV-43A …

Effects of Increased Atmospheric Carbon Dioxide Levels on Tobacco Mosaic Virus and Root-Knot Nematodes in Genetically Resistant and Susceptible Tomato Plants
… Nematode (<em>Meloidogyne arenaria</em>) and Tobacco Mosaic Virus (TMV) infection in genetically resistant versus susceptible tomatoes (<em>Solanum lycopersicum</em>). Both resistant and susceptible tomatoes were grown in chambers with either ambient CO<sub>2</sub> or CO<sub>2 </sub>elevated …

Biochemical and histological investigations of viral localisation in the hypersensitive reaction of Phaselous vulgaris L. var Pinto to tobacco mosaic virus infection
… reaction of Phaseolus vulgaris L. var Pinto to tobacco mosaic virus infection. The infection of Phaseolus vulgaris L. var Pinto with tobacco mosaic virus (TMV) results in the production of distinct necrotic lesions confining the virus to restricted areas of the leaf surface. Biochemical and …

Control of the aphid vectors of plant virus diseases by the use of systemic intersections: Thesis submitted for the National Diploma in Horticulture N.D.H. (N.Z.)
… difference between the pathogen we now call a virus and micro-organisms He showed that the cause of tobacco mosaic virus disease could pass through a bacteria proof filter. His work was repeated by Beijerinck in 1898 who introduced his theory of a"contagium vivum fluidum'! Both he, and Baur in …

Immunoassays with chemically modified bacteriophage
… and the present work represents such an attempt. Tobacco mosaic virus (TMV) was chosen as a model system since it permits the study of numerous inununological phenomena (Rappaport, 1965; van Regenmortel, 1966). A series of preliminary experiments were performed to obtain experience in the …

Characterization of the Pathway Leading to the Synthesis of Salicylic Acid in Plants Resisting Pathogen Infection.
… susceptible and resistant plants challenged with tobacco mosaic virus. Because SA synthesis shares chorismate as a common substrate with the synthesis of aromatic amino acids, HPLC was used to determine whether the increase in SA could be attributed to a decrease in amino acid levels. The results …

Conjugation of Biological and Carbon Nanoparticles For Applications In Electronics and Cell Imaging
… improvement of the method of mineralization of viruses and virus-like particles based on a two-step chemical modification via click chemistry to introduce a pyridine-based ligand scaffold to the exterior of the protein surface of the tobacco mosaic virus (TMV). This ligand system shows an …

The initial characterization of GW6210, a newly isolated bacteriophage for Gluconobacter
… Bradley's group A and tentatively placed in the virus family Myoviridae. This intensive electron microscopic study shows phage GW6210 to have a polygonal head, collar, tail sheath, baseplate, and tail pins. This phage is primarily unusual because of its large size. Using Tobacco Mosaic Virus as …
