SATELLITE TOBACCO MOSAIC VIRUS

Annual Review of Phytopathology, 1998
▪ Abstract  Satellite tobacco mosaic virus (STMV) is a small, spherical ssRNA virus common in a natural wild plant, Nicotiana glauca or tree tobacco, in southern California and is one of the best-studied satellite viruses. It is the only satellite virus that has rod-shaped viruses (tobamoviruses) for its helper.

13C enrichment of Tobacco Mosaic Virus

Biochemical and Biophysical Research Communications, 1980
13C NMR spectra of Tobacco Mosaic Virus with enhanced signal-to-noise ratio have been obtained by isotope enrichment up to 15 %, using 13CO2 as the carbon source, obtained from Ba 13CO3 90 % enriched, and tobacco leaves as the substrate. Determination of the enrichment percentage of TMV is made by IR spectroscopy of the CO2 mixture resulting from ...

Assembly of tobacco mosaic virus

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1976
The assembly of tobacco mosaic virus requires the presence of a particular protein aggregate, the disk. During the nucleation, a specific region of the RNA interacts with a single disk, to bring about a necessarily cooperative transition from the paired two-layer structure to a short segment of nucleo-protein helix. There is a high selectivity for this

Pseudovirions of tobacco mosaic virus

Virology, 1971
Abstract Tobacco mosaic virus (TMV) preparations contain a small percentage of pseudovirions. These particles, which are thought to consist of host RNA encapsidated with TMV protein, can be separated from virus particles by electrophoresis in 0.5% agarose gel. Pseudovirion RNA is smaller than and has a broader size distribution than viral RNA.

Interaction of tobacco mosaic virus and tobacco mosaic virus protein with bovine serum albumin

Archives of Biochemistry and Biophysics, 1977
Abstract Bovine serum albumin (BSA) causes tobacco mosaic virus (TMV) to crystallize at pH values where both have negative charges. The amount of albumin required to precipitate the virus varies inversely with ionic strength of added electrolyte. At pH values above 5, the precipitating power is greatest when BSA has the maximum total, positive plus ...

Distribution of Radiocarbon in Tobacco Mosaic Virus

Nature, 1955
WE have made radioactive tobacco mosaic virus by exposing leaves from infected tobacco plants to radioactive carbon dioxide for one day in light, treating the homogenized leaves with buffer solution, and purifying the virus by repeated precipitation at the isoelectric point1.

Structure of the Tobacco Mosaic Virus Particle; Polymerization of Tobacco

1968
Publisher Summary The chapter describes a critical analysis of the molecular weight of tobacco mosaic virus (TMV) and with polymerization of TMV protein. TMV has a very high molecular weight and measurements of double refraction of flow led to the conclusion that the particles are rod-shaped. The molecular weight of TMV has been determined adequately

Fine Structure of Tobacco Mosaic Virus

Nature, 1956
ALTHOUGH tobacco mosaic was one of the first viruses to be examined in the electron microscope, electron microscopy has failed to reveal any fine structure, even though it has been repeatedly looked for1,2, especially since the introduction3 of metal shadow casting in 1945.

Cation binding by tobacco mosaic virus

Virology, 1977
Abstract Hydrogen ion titration curves of tobacco mosaic virus and its protein, alone or in the presence of various multivalent ions, have been measured. Three groups titrating near neutral pH in the virion have significant metal ion binding, but the tightest of these binding sites, significantly specific for Ca 2+ over Mg 2+ appears to be absent ...

ZONE ELECTROPHORESIS OF TOBACCO MOSAIC VIRUS

Canadian Journal of Biochemistry and Physiology, 1959
An apparatus is described for the preparative zone electrophoresis of tobacco mosaic virus in agar gel. The isolated virus does not have any detectable ribonuclease activity.
