2. CMV is made up of nucleic acid (ribonucleic acid, RNA) surrounded by a protein coat. Once inside the plant cell, the protein coat falls away and the nucleic acid portion directs the plant cell to produce more virus nucleic acid and virus protein, disrupting the normal activity of the cell
3. Cucumber mosaic is caused by Cucumber mosaic virus (CMV) which can overwinter in susceptible biennial or perennial weeds, as well as in perennial agricultural crops (e.g., alfalfa) and perennial herbaceous and woody ornamentals
4. Cucumber mosaic is the most destructive and widespread disease of cucumber and muskmelonsworldwide. All vine crops as well as a wide range of annual, biennial, and perennial crop and weed plantsin about 40 families are attacked (Table 1). The virus is made up of many and varied strains that differin a number of aspects including host range, symptoms, and means of transmission. The strains of CMVare differentiated on the basis of symptoms on indicator host plants
5. Cucumber Mosaic Virus Cucumber Mosaic Virus (CMV) can cause severe losses in vegetables, legumes, and ornamentals. The virus is distributed worldwide but is particularly prevalent in temperate regions. It has a host range of more than 1,200 species, and is transmitted by many species of aphids, as well as cucumber beetles
6. The cucumber mosaic virus overwinters in perennial weeds and may be transmitted to healthy plants by aphid vectors (although tomatoes are not the preferred host of aphids) or by mechanical means. The cucumber mosaic virus cannot withstand drying or persist in the soil. It also is more difficult than tobacco mosaic to transmit mechanically. Thus, cucumber mosaic tends to progress more slowly than tobacco mosaic in a field or garden

Cucumber Mosaic Virus Symptoms Cucumber Mosaic Virus symptoms are rarely seen in cucumber seedlings. Signs become visible at about six weeks during vigorous growth. The leaves become mottled and wrinkled and the edges curl downward Cucumber mosaic virus (CMV) is probably the most widely distributed and important virus disease of cucurbits in New York. The virus overwinters in many perennial weed sources especially attractive to aphids when weed growth resumes in the spring. Early infection of squash and melons is particularly common Effects of sowing seed with different levels of infection, plant density and the growth stage at which plants first develop symptoms on cucumber mosaic-virus infection of narrow-leafed lupins (Lupinus angustifolius).

1. Mosaic Cucumber Virus is one beast of a disease, and unfortunately once infected, the plant cannot be cured. This virus is most often spread by aphids, and can live in the soil that the plants inhabit. It can even over-winter in perennial and weed roots, returning with the new growth in the spring. The virus is fairly easy to spot
2. CUCUMBER MOSAIC The disease, cucumber mosaic, is caused by the Cucumber mosaic virus (CMV)
3. Mosaic virus overwinters on perennial weeds and is spread by insects that feed on them. Aphids, leafhoppers, whiteflies and cucumber beetles are common garden pests that can transmit this disease. Soil, seed, starter pots and containers can be infected and pass the virus to the plant
4. Historically, Cucumber mosaic virus (CMV) was first described in detail in 1916 on cucumber (simultaneously by Doolittle and Jagger) ( Figures 1, 2) and other cucurbits, but is now known to occur worldwide in both temperate and tropical climates, affecting many agricultural and horticultural crops. Development of genetic resistance to CMV in.
5. Symptoms. Symptoms vary widely, depending on the host plant; possibilities include distorted foliage, mosaic, mottling, stunting and necrosis. Symptoms can resemble herbicide injury. Mottling on lily. Spread. This virus is spread by several aphid vectors. Aphids acquire and transmit virus particles by probing or feeding on plant tissues
6. Cucumber mosaic virus exists in numerous strains that differ somewhat in their hosts, in the symptoms they produce, in the ways they are transmitted, and in other properties and characteristics (Agrios, 1978; Francki et al., 1979)

The ANS provides high proportions of micronutrient content and has medicinal, economic, and agronomic benefits. In this study, we utilized molecular methods to detect these viruses present in ANS at two locations in Kenya: Kisii and. Cucumber mosaic virus (CMV) causes plants to become yellow, bushy and very stunted. Leaves may be extremely distorted and malformed. Leaflets are often very narrow - this is called shoestring. Often the leaves on one portion of the plant (e.g., the top or the bottom) show severe symptoms, while those higher or lower in the plant are less. Aphids are a primary carry of this virus. Cucumber mosaic virus symptoms also include a mosaic/mottling pattern (as described above) as well as the stunting. This virus can be found in other vegetables such as tomato, carrot, celery, cucurbits, legumes, lettuce, spinach, and pepper

You may find this in various degrees, with some squash showing only minor.

Like other plant viruses, cucumber mosaic virus interferes with genetic signalling within the plant. Leaves that are distorted by the virus cannot function normally, so plants struggle to grow and stop gaining size. The yellow patches on leaves turn to brown as the disease advances Cucumber mosaic virus (CMV) does not affect only cucumbers. It also targets: Squash.Melons.Peppers.Tomatoes.Beets.Spinach.Celery.Petunias. The disease is primarily spread by aphids, but it can also be spread by cucumber beetles and on gardening tools.

The virus, spread by aphids, causes symptoms in the plants within three weeks. In papayas, young plants die quickly, while older, productive plants show yellow leaves which drop. The fruits have blemishes, and the compromised trees produce fewer and smaller fruits until they eventually die Other viruses that affect orchids, such as orchid fleck virus (OFV), cucumber mosaic virus (CMV) and several poty- and tospoviruses, among others, are transmitted by arthropods such as mites, and insects such as aphids and thrips. Although less common in orchids, they can occur and cause damage to the plants The virus infects fruit and vegetables belonging to the family Cucurbitaceae; including watermelon, cucumber, melons, zucchini, pumpkin, squash, bitter gourd, and bottle gourd and has been found in Cucurbitaceae weeds. There are at least five strains of the virus, and symptoms can vary between hosts. Other mosaic diseases, caused by potyviruses.

Other viruses, such as cucumber mosaic virus, squash mosaic virus and others also can occur, but their biology and management are similar. Symptoms: Symptoms caused by the different viruses are usually similar and more than one virus may be present in plants exhibiting symptoms. Plants can be infected at any stage of growth In cucumber, symptoms appear 7-14 days after infection. At low temperatures, when the plants grow more slowly, leaf distortion is more severe ( Smith, 1972 ). In the field, the virus causes mosaic and occasionally wrinkling, green vein-banding and stunting of muskmelons. In the greenhouse it causes mild chlorosis, mosaic, vein-banding, and at. Cause Mosaic symptoms may be due to any of 3 viruses including Cucumber mosaic virus (CMV), Plantago asiatica mosaic virus (formerly Nandina mosaic virus) and/or Nandina stem pitting virus (NSPV). All of these viruses are easily transmitted through vegetative propagation of the host. CMV can also be vectored by a wide variety of aphids Plants will often show stunting, leaf curling, and fruit distortion along with the mosaic pattern on leaves. Symptoms may be similar to those caused by cucumber mosaic virus. COMMENTS ON THE DISEASE. All of the potyviruses affecting pepper are transmitted from plant to plant by several species of aphids

Cucumber mosaic virus (CMV) is one of the most common plant viruses and causes a wide range of symptoms, especially yellow mottling, distortion and stunting. Expect damage whenever susceptible plants are growing well in spring and summer. Apart from cucumbers and other cucurbits, CMV also attacks spinach, lettuce and celery and many flowers. A survey on the occurrence and incidence of Cucumber mosaic virus (CMV) was carried out on selected horticultural crops in Peninsular Malaysia. A total of 1293 leaf samples showing virus-like symptoms comprising of chilli (527 samples), tomato (63 samples), eggplant (183 samples), cucumber (20 Shown at the left is the leaf symptoms of cucumber mosaic virus (image courtesy of www.whitefly.org). Fortunately, trees and Australian native plants have few virus disease problems and, interestingly, viruses in wild-growing plants don't seem to develop disease, although they have not been studied as well as cultivated plants Reduced leaflet size -- many individual viruses like tobacco mosaic, cucumber mosaic and pseudo curly top as well as virus combinations can produce this symptom. Stunting -- pseudo curly top geminivirus and combinations of viruses can reduce plant vigor causing a stunted plant Alfalfa mosaic virus may be confused with cucumber mosaic virus, because it too is widespread, causes similar symptoms in some hosts and is also transmitted by aphids in the non-persistent manner. However, most strains of alfalfa mosaic virus, unlike cucumber mosaic virus, give local lesions in Phaseolus vulgaris at all times of the year, and.
