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 ...
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 .
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.
This virus is transmitted by an insect vector from the family Aleyrodidae and order Hemiptera, the whitefly Bemisia tabaci, commonly known as the silverleaf whitefly or the sweet potato whitefly. The primary host for TYLCV is the tomato plant, and other plant hosts where TYLCV infection has been found include eggplants, potatoes, tobacco, beans ...
Curly top virus, have a very wide host range within dicot plants, including over 300 species in 44 plant families (Strausbaugh et al., 2008). [12] The most common infected hosts include sugar beets (for which the disease was first named), follow by tomatoes, [ 13 ] peppers, beans, potatoes, spinach, cucurbits, cabbage, alfalfa, and many ...
The electrical penetration graph or EPG is a system used by biologists to study the interaction of insects such as aphids, thrips, and leafhoppers with plants. Therefore, it can also be used to study the basis of plant virus transmission, host plant selection by insects and the way in which insects can find and feed from the phloem of the
The amount of time it takes for insects to acquire the virus (acquisition period) and the amount of time it takes for the virus to move from the insect to the plant (inoculation) for TSWV varies depends on the vector species. [2] For F. occidentalis, the acquisition and inoculation of TSWV can be as short as 5 minutes. However, the acquisition ...
Aphid species Myzus persicae. The cauliflower mosaic virus (CaMV) is a member of the family Caulimoviridae.This family is grouped together with the Belpaoviridae, Metaviridae, Pseudoviridae, and Retroviridae (all of which instead have an RNA genome replicated via a DNA intermediate) in the order Ortervirales; the Hepadnaviridae, despite having a DNA genome replicated via an RNA intermediate ...
