The involvement of a helper component in nonpersistent transmission of plant viruses by aphids.

Microbiological sciences, 1990
Certain plant viruses require a 'helper component' in order to be transmitted by aphids. The helper component for potyviruses is a virus-encoded protein with a subunit molecular weight of between 50,000 and 60,000. Aphid transmission of caulimoviruses is associated with the presence of an 18,000 molecular weight polypeptide.
