CMV is one of the most common and destructive cucurbit viruses, and it is widely distributed throughout temperate and tropical areas of the world. Cucumber mosaic virus can infect plants from over forty families, including vegetable crops like tomato, lettuce and spinach, flower crops like gladiolus, petunias, impatiens and rudbekia, and a wide variety of weeds. But now we have six other cucumber plants that look quite different, and this time I'm pretty confident that it is the cucumber mosaic virus… Despite the fact that CMV has only 19% capsid protein sequence identity (34% similarity) to cowpea chlorotic mottle virus (CCMV), the core structures of these two members of the Bromoviridae family are highly homologous. Mosaic virus overwinters on perennial weeds and is spread by insects that feed on them. This review focuses on those areas where most progress has been made over the past decade in our understanding of CMV. Vegetable hosts include carrot, celery, cucurbits, legumes, lettuce, onion, 1,2 CMV can infect over 1200 plant species including both monocots and dicots. The virus overwinters in many perennial weed sources especially attractive to aphids when weed growth resumes in the spring. Cucumber mosaic virus (CMV) is a plant virus that attacks a number of species, including cucumbers and many other vining plants as well as tomatoes, potatoes and others. The yellow patches on leaves turn to brown as the disease advances. All of the mosaic viruses can also infect weeds in the cucurbit family. We had to remove three cucumber plants because they seemed to have some sort of disease that we thought was the cucumber mosaic virus. Early infection of … Leaves that are distorted by the virus cannot function normally, so plants struggle to grow and stop gaining size. The disease affects a number of important vegetables and ornamentals including tomato, pepper, cucumber, melons, squash, spinach, celery, Cucumber mosaic virus (CMV) is probably the most widely distributed and important virus disease of cucurbits in New York. The structure of cucumber mosaic virus (CMV; strain Fny) has been determined to a 3.2-Å resolution using X-ray crystallography. 3 (4), 291-298. It has a host range of more than 1,200 species, and is transmitted by many species of aphids, as well as cucumber beetles. Cucumber Mosaic Virus (CMV) can cause severe losses in vegetables, legumes, and ornamentals. Description: The cucumber mosaic virus has one of the broadest host ranges of any of the tomato viruses. It is the most widely distributed plant virus in terms of possible affected species. Cucumber green mottle mosaic virus (CGMMV) is a re-emerging threat to greenhouse cucumber and other Cucurbitaceae crop production worldwide. Cucumber leaves afflicted with various stages of Cucumber mosaic virus A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Zambolim E M, Assis M I T, Zambolim L, Venturia J A, Carvalho M G de, 1994. The disease, cucumber mosaic, is caused by the Cucumber mosaic virus (CMV). Preventing Problems: Soil, seed, starter pots and containers can be infected and pass the virus to the plant. CUCUMBER MOSAIC. Korean Journal of Plant Pathology. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses. Blackeye cowpea mosaic virus and cucumber mosaic virus causing mosaic disease on asparagus bean (Vigna sesquipedalis) in Korea. CMV affects a large number of plants grown for food all over the world. Cucumber mosaic virus (CMV) is an important virus because of its agricultural impact in the Mediterranean Basin and worldwide, and also as a model for understanding plant–virus interactions. Like other plant viruses, cucumber mosaic virus interferes with genetic signalling within the plant. The virus is distributed worldwide but is particularly prevalent in temperate regions. This seed-borne virus can easily spread from a contaminated seeds to seedlings and to adjacent plants through mechanical contact of the foliage of diseased and healthy plants causing extensive yield losses. Aphids, leafhoppers, whiteflies and cucumber beetles are common garden pests that can transmit this disease.
