An essential step in the initiation of a virus infection is the release of the viral genome from the other constituents of the virus particle, a process referred to as uncoating. We have used reverse transcription and polymerase chain reaction amplification procedures to determine the rate and direction of in vivo uncoating of the rod-shaped tobacco mosaic virus. The virus particles contain a single 6.4-kb RNA molecule that lies between successive turns of a helical arrangement of coat protein subunits. When the particles are introduced into plant cells, the subunits are removed via a bidirectional uncoating mechanism. Within 2-3 min, the part of the viral RNA from the 5' end to a position &gt;70% toward the 3' end has been freed of coat protein subunits. This is followed by removal of subunits from the 3' end of the RNA and sequential uncoating of the RNA in a 3'-to-5' direction. An internal region of the viral RNA is the final part to be uncoated. Progeny virus particles are detected in the cells 35-40 min after inoculation.
