Virus Notes
... •Viruses are segments of nucleic acid (DNA or RNA) contained in a protein coat (capsid); some also have an envelope. •Viruses have NO cell membrane, nucleus, or organelles. It does not eat/metabolize. •It is not considered to be a living thing. •About 1/10 size of most bacteria ...

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.
