Transmission of plant viruses by aphid vectors.
SUMMARY Aphids are the most common vector of plant viruses. Mechanisms of transmission are best understood by considering the routes of virus movement in the aphid (circulative versus non-circulative) and the sites of retention or target tissues (e.g. stylets, salivary glands). Capsid proteins are a primary, but not necessarily sole, viral determinant of transmission. A summary is presented of the taxonomic affiliations of the aphid transmitted viruses, including 8 families, 18 genera, and taxonomically unassigned viruses.
