  • Title: Inhibition of uncoating of tobacco mosaic virus particles in protoplasts from transgenic tobacco plants that express the viral coat protein gene.
    Author: Wu XJ, Beachy RN, Wilson TM, Shaw JG.
    Journal: Virology; 1990 Dec; 179(2):893-5. PubMed ID: 2238480.
    Abstract:
    The uncoating of tobacco mosaic virus (TMV) particles in protoplasts isolated from leaves of transgenic tobacco plants that express the TMV coat protein gene was investigated. Extracts of these protoplasts collected up to 1 hr after inoculation with TMV contained fewer of the complexes ("striposomes") thought to be involved in cotranslational disassembly of virus particles than did extracts of protoplasts that do not express the viral coat protein gene. These results are consistent with the hypothesis that TMV coat protein-mediated resistance is at least in part the result of inhibition of the uncoating of the virus particles in the inoculum.
