ABSTRACT
1. Plant viruses can only enter their host through a wounded plant cell. Once in the cytoplasm, the virion must be disassembled, and for certain viruses with a "+" RNA genome, cotranslational disassembly of virus particles has been described. 2. Subsequent to viral protein synthesis which requires the host translational machinery, the "+" RNA genome is replicated in the cytoplasm. Viral genome amplification requires at least one viral-coded non-structural protein in conjunction with one or more host factors. 3. Early events in virus infection can be studied in systems that hinder these events. This is the case of natural hosts that are resitant to viruses mutant viruses which overcome such resistance have been described. It is also the case of genetically engineered plants that are protected from virus infection. Both types of systems should help in determining the mode of interaction involved, and possibly also the host factor(s) involved in the various steps of virus infection
