It has a host range of more than 1,200 species, and is transmitted by many species of aphids, as well as cucumber beetles. Vegetable hosts include carrot, celery, cucurbits, legumes, lettuce, onion, pepper, spinach, tomato, and rarely potato. Many woody and non-woody ornamentals are also hosts.
What plants get cucumber mosaic virus?
Cucumber mosaic virus (CMV) causes severe disease in lentils, chickpeas and lupins. In areas where large aphid populations occur, crop losses can be high due to reduced herbage production and grain yield.
What causes mosaic virus in cucumbers?
What causes Cucumber Mosaic disease is the transfer of the virus from one infected plant to another through the bite of an aphid. The infection is acquired by the aphid in just one minute after ingestion and is gone within hours.
Which crop is affected by mosaic disease?
mosaic, plant disease caused by various strains of several hundred viruses. A number of economically important crops are susceptible to mosaic infections, including tobacco, cassava, beet, cucumber, and alfalfa.
What plants can get mosaic virus?
Mosaic viruses affect a wide range of edible crops – alfalfa, apples, beans, celery, corn, cucumbers, figs, peppers, spinach, tobacco and tomatoes are some of the more common ones. They can also infect ornamental plants like abultilon, delphinium, gladiola, marigold, petunia and one of the most notable, roses.
What does cucumber mosaic virus affect?
Cucumber mosaic virus (CMV) is one of the most common plant viruses, causing yellow mottling, distorted leaves and stunted growth in a wide range of garden plants, not just cucumbers.
What is the scientific name of cucumber mosaic virus?
Genus: Cucumovirus. Species: Cucumber mosaic virus.
How do cucumbers control the mosaic virus?
There are no chemicals that cure a CMV-infected plant, nor any that protect plants from becoming infected.
- Purchase virus-free plants.
- Maintain strict aphid control.
- Remove all weeds since these may harbor both CMV and aphids.
- Immediately set aside plants with the above symptoms and obtain a diagnosis.
Is cucumber mosaic virus seed borne?
Analysis of individual whole seeds showed that seed-borne infection of CMV in pepper ranged from 95 to 100%. Further seed-growth tests were performed in Petri dishes and CMV was detected in both seed coat and embryo. Seed coat infection of CMV ranged from 53 to 83% while that of the embryo ranged from 10 to 46%.
Can cucumber mosaic virus spread to other plants?
Watermelon mosaic virus infects legumes like clover. 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 rudbeckia, and a wide variety of weeds.
Who is the carrier of Pigeonpea sterility mosaic disease Mcq?
Transmission of Pigeon pea sterility mosaic virus by the Eriophyid Mite, Aceria cajani (Acari: Arthropoda)
Which of the following organisms cause bean mosaic disease in plants?
Begomovirus and YMD in Vigna
The genus name Begomovirus was derived from the type member, Bean Golden MOsaic virus (BGMV), causing golden mosaic disease in beans.
Is cucumber mosaic virus harmful to humans?
“These viruses are specific to plants and do not harm humans. The presence of mosaic won’t cause fruits to rot prematurely but severely distorted fruit will have a different texture, so use your own judgement.”
What is mosaic formation in plants?
Mosaic formation is the presence of some light and dark green patches in the leaves of plants which is mainly caused by the viral diseases. Leaf rolling is curving the leaves of plants outwards. Due to some diseases the plant which is mostly green in color gets converted into the yellow color plant.
What causes mosaic in tomatoes?
The tomato potyviruses are transmitted plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and localized.
What is the name of the plant pathogen that destroys leaves leaving a mosaic appearance?
Tobacco mosaic virus and the closely related tomato mosaic virus cause mosaic/mottling (sometimes with a blister-like appearance) of leaves, flowers, and fruit and cause the stunting of plants.
What are the diseases of cucumber?
» Angular leaf spot, bacterial wilt, Phytophthora crown and root rot, and powdery mildew are important diseases on cucumber.
When was cucumber mosaic discovered?
Cucumber mosaic virus (CMV) was first described as a disease of cucurbits in 1916 by Doolittle in Michigan and Jagger in New York. The virus can infect a large number of indicator plant species and has been isolated from over 500 naturally infected species.
Which kind of nucleic acid is found in cucumber mosaic virus?
Cucumber mosaic virus (CMV) is an isometric plant virus with a tripartite plus-sense RNA genome (Palukaitis et al., 1992).
What causes mosaic virus in squash?
Squash mosaic virus (SqMV) can cause an important disease of melons and squash in New York. The virus is seedborne in muskmelon and is spread in nature principally by the spotted and striped cucumber beetles.
What is the nucleic acid found in the tobacco mosaic virus?
ribonucleic acid; RNA
TMV is made up of a piece of nucleic acid (ribonucleic acid; RNA) and a surrounding protein coat. The complete virus is a submicroscopic, rigid, rod-shaped particle.
