More recently virus research has been focused on understanding the genetics and molecular biology of plant virus genomes, with a particular interest in determining how the virus can replicate, move and infect plants. Understanding the virus genetics and protein functions has been used to explore the potential for commercial use by biotechnology ...
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.
The most commonly infected cultivated plants are endive, escarole, and lettuce. Other plants such as pea, safflower, and spinach may also become infected. [1] Lettuce mosaic virus has a wide range of symptoms which depend on the cultivar or the type of lettuce, the age of the plant when infected, and the conditions of the environment. [1]
The symptoms can be different depending on how bad the infection is and how far along the plant is in its growth. Extensive necrosis can cause damaged leaves to become dry and dead. If a plant is infected in its early development stages, its growth may be stunted. The virus can also hurt the quality and yield of lettuce crops. [12]
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 RNA genomes that infect ...
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 ...
Apple mosaic virus (ApMV) is a plant pathogenic virus of the family Bromoviridae. It is named after its symptoms that were first present on apples. [1] ApMV is a positive sense RNA based virus. [1] The disease itself has several synonyms including Mild Apple Mosaic Virus, Hop Virus, Rose Mosaic Virus, and European Plum Line Patten Virus. [2]
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.
