Transmission of Viruses Through Nematodes,test soil. Plants are grown in the soil to allow any viruliferous nematodes to feed and transmit the virus. Sap extracted from roots and leaves of the bait plants are then inoculated mechanically with a range of indicator hosts to confirm and identify the associated virus.

At least 45 viruses, belonging to 16 genera and five viroids, have been described as pollen-transmitted. The process of virus transmission through pollen is discussed in the chapter.

A few of the viruses have the ability to infect only a limited number of hosts while a few other viruses have the ability to infect large number of hosts belonging to several plant genera and families. Plant hosts play an important role in biological characterization of a plant virus.

The dodder can be used for experimental transmission of viruses under controlled conditions.

Unlike vectors, infected seeds can be carried away to distant places where they act as primary source of inoculum for spread of a virus. A few of the seed-borne viruses may be carried as surface contaminants while others are carried through embryo considered as true seed-borne viruses.
