Plant and Animal Viruses as Vectors

Plant and Animal Viruses as Vectors - A number of plant and animal viruses have also been used as vectors both for introducing foreign genes into cells and for gene amplification and expression in host cells. In the latter case, we may be interested only in getting increased quantity of the gene product and may not be interested in the integration of the foreign gene in the host genome. Some of the viruses that are commonly used as vectors will be described in this section.
