Plant virus, any of a number of agents that can cause plant disease. Plant viruses are of considerable economic importance because many of them infect crop and ornamental plants. Numerous plant viruses are rodlike and can be extracted readily from plant tissue and crystallized.

Infectious plant diseases are mainly caused by pathogenic organisms such as fungi, bacteria, viruses, protozoa, as well as insects and parasitic plants [1]. With the development of agriculture, infectious plant diseases have become an increasingly significant factor affecting crop yield and economic efficiency.

Plant viruses are viruses that have the potential to affect plants. Like all other viruses, plant viruses are obligate intracellular parasites that do not have the molecular machinery to replicate without a host. Plant viruses can be pathogenic to vascular plants ("higher plants").

2011年10月21日 · The Top 10 list includes, in rank order, (1) Tobacco mosaic virus, (2) Tomato spotted wilt virus, (3) Tomato yellow leaf curl virus, (4) Cucumber mosaic virus, (5) Potato virus Y, (6) Cauliflower mosaic virus, (7) African cassava mosaic virus, (8) Plum pox virus, (9) Brome mosaic virus and (10) Potato virus X, with honourable mentions for ...

2023年6月5日 · Plant viruses rely on two main strategies to spread in the plant host: local movement, which occurs between adjacent cells, and systemic movement through the plant vasculature. Upon inoculation, a virus will establish an infection by translating viral proteins and initiating its replication to generate new progeny, which then move to adjacent ...

Plant viruses are a major threat to crop production and sustainable agriculture, diminishing their yield and/or produce quality. More than 1000 virus species infecting cultivated plants worldwide have been described.

Some of the best characterized beneficial viruses that have been used in plants are those that enhance the beauty of ornamental plants. Tulip breaking virus was the first of a long list of the beautiful viruses, but many other prized ornamentals owe their value, at least in part, to the viruses that infect them (Valverde et al., 2012).

2019年11月3日 · Plant viruses are particles of RNA or DNA that infect plants and cause disease. Most plant viruses are single-stranded RNA or double-stranded RNA viruses. Common plant viruses include mosaic viruses, spotted wilt viruses, and leaf curl viruses.

2019年7月16日 · In this Review, we focus on the origins of plant viruses and the evolution of interactions between these viruses and both their hosts and transmission vectors. We also identify currently...

Plant viruses encode specialized movement proteins to modify the narrow plasmodesmata channels that traverse the thick cell wall, thereby allowing cell-to-cell movement of viral RNA complexes or virus-like particles (Harries and Ding, 2011; Heinlein, 2015). Finally, plants deploy an arsenal of antiviral defense responses that viruses must ...
