Some Conditions Affecting the Intracellular Arrangement and Concentration of Tobacco Mosaic Virus Particles in Local Lesions
Tobacco mosaic virus particles were found in small packets and in small numbers, with the electron microscope, in necrotic leaf cells of Nicotiana glutinosa when the samples were fixed in glutaraldehyde and postfixed in OsO(4), and the sections were stained with heavy metals. The numbers and size of the virus packets were increased greatly when the leaves were detached from the plant after inoc...

The isoelectric points of some strains of tobacco mosaic virus.
The detailed amino acid analysis of several strains of tobacco mosaic virus carried out by Knight (1) has revealed interesting chemical similarities and differences among these strains, although they are morphologically very similar (2). In the present work the isoelectric points of the strains which Knight has analyzed were determined by a method developed by the author (3). The virus strains ...

متن کاملThe nucleic acids of some strains of tobacco mosaic virus.
Investigation of the protein compositions of highly purified preparation8 of eight strains of tobacco mosaic virus revealed that each strain possesses a characteristic composition which in several instances could be demonstrated to differ significantly from that of the other strains (1). The differences found consist mainly of altered proportions of certain amino acids, but it was also found th...
