The structural differences between plant and animal cells have resulted in a variety of transmission routes being exploited, enabling the virus to be passed between different host plants. The main difference, from the point of view of a virus, is the cell wall .
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 ...
Caulimoviruses achieve entry into plant cells via damaged tissues, transmission via an animal vector (aphid insects) and seeds passed down to generations.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.
Plant viruses are generally transmitted by a vector, but mechanical and seed transmission also occur. Vectors are often insects such as aphids ; others are fungi , nematodes , and protozoa . In many cases, the insect and virus are specific for virus transmission such as the beet leafhopper that transmits the curly top virus causing disease in ...
Mastrevirus and curtovirus transmission is via various leafhopper species (e.g. maize streak virus and other African streak viruses are transmitted by Cicadulina mbila), the only known topocuvirus species, Tomato pseudo-curly top virus, is transmitted by the treehopper Micrutalis malleifera, and begomoviruses are transmitted by the whitefly ...
The virus can be efficiently transmitted during the adult stages. This virus transmission has a short acquisition access period of 15–20 minutes, and latent period of 8–24 hours. In this plant-virus and vector system, females are more effective than males transmitting the virus. [1]
West Nile virus; Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people. [21] Humans can also be vectors for some diseases, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant. [citation needed]
Though generally found in arthropods or rodents, certain viruses in this order occasionally infect humans. Some of them also infect plants. [6] In addition, there is a group of bunyaviruses whose replication is restricted to arthropods and is known as insect-specific bunyaviruses. [7] A majority of bunyaviruses are vector-borne.
