... 11) Viral Replication is how a virus makes copies of itself. A virus CANNOT reproduce by itself—it must invade a host cell and take over the cell’s “machinery”, make copies of itself, and eventually will cause the cell to burst (lyses), releasing more viruses. This kills the host cell. ...

Plant virus
Plant viruses are viruses that affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses are pathogenic to higher plants. While this article does not intend to list all plant viruses, it discusses some important viruses as well as their uses in plant molecular biology.
