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") . Most plant viruses are rod-shaped, with protein discs forming ...
Pepper mild mottle virus. Pepper mild mottle virus ( PMMoV) is a plant pathogenic virus that occurs worldwide on species of field grown bell, hot and ornamental pepper species. It is caused by members of the plant virus genus Tobamovirus —otherwise known as the tobacco mosaic virus family. Tobamovirus are viruses that contain positive sense ...
Cucumber mosaic virus ( CMV) is a plant pathogenic virus [1] in the family Bromoviridae. [2] This virus has a worldwide distribution and a very wide host range, [3] having the reputation of the widest host range of any known plant virus. [4] It can be transmitted from plant to plant both mechanically by sap and by aphids in a stylet-borne fashion.
Tobacco mosaic virus ( TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves (hence the name).
Symptoms of sugarcane mosaic virus include intense mottling throughout the laminar region of the plant, characterized by discoloration of the plants leaves, and growth stunting. [6] In maize, the infection occurs first in the youngest leaves with symptoms such as irregular, light or dark green mosaic coloring developing along the veins.
Tulip breaking virus is one of five plant viruses of the family Potyviridae that cause color-breaking of tulip flowers. These viruses infect plants in only two genera of the family Liliaceae: tulips ( Tulipa) and lilies ( Lilium ). Also known as the tulip break virus, lily streak virus, lily mosaic virus, or simply TBV, Tulip breaking virus is ...
The infection is generally restricted to plants that are grown in seedbeds and transplanted as it is in the handling processes that the virus is likely to gain entry. Symptoms on other plant hosts include blistering, chlorosis , curling, distortion, dwarfing and mottling of the leaves.
Tobacco rattle virus. 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.
