Lettuce mosaic virus is a very common and economically important viral disease that affects lettuce worldwide. The virus spread due to an increased exchange of seeds of various lettuce varieties between countries. [3] It was first recorded in 1921 in lettuce crops in Florida. [1] Since then it has been found in most of the world's major lettuce ...
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]
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.
A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
Barley yellow mosaic virus is plant pathogenic virus that causes the yellow mosaic disease of barley. Its shape is categorized as being flexuous filamentous, with lengths of 275 and 550 nanometers. The virus has a limited host range, and barley appears to be the only known susceptible host. [ 1 ]
Squash mosaic virus (SqMV) is a mosaic virus disease common in squash plants and other plants, including melons, of the family Cucurbitaceae. [1] It occurs worldwide. [1] It is transmitted primarily by beetles, including the leaf beetle (Acalymma trivittata), spotted cucumber beetle (Diabrotica undecimpunctata), [2] [3] and 28-spotted ladybird beetle (Henosepilachna vigintioctopunctata), [1 ...
Barley stripe mosaic virus (BSMV), of genus Hordevirus, is an RNA viral plant pathogen whose main hosts are barley and wheat. The common symptoms for BSMV are yellow streaks or spots, mosaic, leaves and stunted growth. It is spread primarily through infected seed and can be spread through mechanical transfer of an infected and uninfected host.
The virus can result in severe yield loss of the infected host and the disease eventually leads to necrosis. [7] Diagnosis of sugarcane mosaic virus is achieved first through recognizing the typical light green mosaic pattern of the infection, electron microscopy of leaf dips, as well as virus isolation and purification methods.
