Plant virus transmission strategies in insect vectors. Plant viruses need to be transmitted by a vector, most often insects such as leafhoppers. One class of viruses, the Rhabdoviridae, has been proposed to actually be insect viruses that have evolved to replicate in plants. The chosen insect vector of a plant virus will often be the ...
A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
Plant cells do not possess receptors like animal cells that would allow the virus to enter and since plant cells are thick, viruses achieve entry as aforementioned. Once inside the plant, the virus spreads using plasmodesmata, a membrane channel found in plants connecting one plant cell to another. Caulimoviruses are para-retroviruses with a ...
When control of plant virus infections is considered economical, for perennial fruits, for example, efforts are concentrated on killing the vectors and removing alternate hosts such as weeds. [13]: 802 Plant viruses cannot infect humans and other animals because they can reproduce only in living plant cells. [13]: 799–807
Caulimoviridae is a family of viruses infecting plants. [1] There are 94 species in this family, assigned to 11 genera. [2] [3] Viruses belonging to the family Caulimoviridae are termed double-stranded DNA (dsDNA) reverse-transcribing viruses (or pararetroviruses) i.e. viruses that contain a reverse transcription stage in their replication cycle.

A number of “vampire viruses” have been discovered in soil samples in Maryland and Missouri for the first time.. The existence of the eerily-nicknamed viruses has been known to researchers for ...
For example, the leafhopper Macrosteles quadrilineatus laid 30% more eggs on plants expressing SAP11 transgenically than control plants and 60% more eggs on plants infected with AY-WB. [23] Phytoplasmas cannot survive in the external environment and are dependent upon insects such as leafhoppers for transmission to new (healthy) plants.
