Interpretive Summary:

Technical Abstract: It has been nearly 100 years since a leafhopper was confirmed as the vector of rice dwarf virus. Several hundred plant viruses have since been identified, a majority of which are dependent upon a vector for transmission between, and inoculation into, plant hosts. The plant viruses have evolved many interesting and biologically complex associations with their vectors, which include arthropods, nematodes and fungi. Although there is a great deal known about the general biology of most virus-vector interactions, we are only beginning to understand the molecular and cellular mechanisms that regulate the transmission processes and determine the efficiency of transmission. The current state of knowledge of the molecular and cellular mechanisms regulating the uptake and transmission of noncirculative and circulative viruses is discussed. The mechanisms of transmission of viruses by fungi is covered under separate headings. In addition, a review is provided on the terminology used in describing virus-vector relationships.
