Since viruses are obligate intracellular parasites they must develop direct methods of transmission, between hosts, in order to survive. The mobility of animals increases the mechanisms of viral transmission that have evolved, whereas plants remain immobile, and thus plant viruses must rely on environmental factors to be transmitted between hosts.
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 ...
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 ...
Adults transmit the virus from infected salivary glands, and uninfected adults will not transmit the virus. Obviously, controlling the infection by limiting transmission from infected plants to larval thrips or by preventing adult dispersal from infected plants are key strategies in preventing an epidemic of the disease.
The INSV virus infects by injecting the RNA the virus contains into the cell which then starts using the cell resources to transcribe what the virus RNA states. [3] Viral infection can often result in the death of the plant. The disease is mainly controlled by the elimination of the western flower thrip vector and by destroying any infected ...
Transmission electron micrograph of tomato spotted wilt virus. The circulative propagative transmission of TSWV is carried out by at least 10 different species of thrips. [2] The most common species is Frankliniella occidentalis (western flower thrips) as it is the vector that predominantly transmits TSWV globally and in greenhouses.
Tobacco rattle virus (TRV) is a pathogenic plant virus. Over 400 species of plants from 50 families are susceptible to infection. [1] The virus causes the plant disease tobacco rattle in many plants, including many ornamental flowers [2] including Narcissus. It causes the disease corky ringspot in potatoes. The disease manifests in various ways ...
The interactions between aphids and CIRV-infected plants have been examined to determine factors influencing these vectors' virus transmission efficiency. Plant-Plant Transmission: Research has also explored non-vector-mediated transmission of CIRV, mainly through mechanical means. Understanding how the virus can be mechanically transmitted via ...
