How long does tobacco mosaic virus live on surfaces?
TMV is geographically widespread and economically significant. TMV is transmitted mechanically and is not known to have an invertebrate vector like some other viruses. It is very stable and persists in the soil and on surfaces and can survive almost 50 years in dead, dried plant tissue.
What are symptoms of TMV?
Symptoms associated with TMV infections:
- mosaic pattern of light and dark green (or yellow and green) on the leaves.
- malformation of leaves or growing points.
- yellow streaking of leaves (especially monocots)
- yellow spotting on leaves.
- distinct yellowing only of veins.
Can plants recover from virus?
Virus-induced diseases cause severe damages to cultivated plants resulting in crop losses. Interestingly, in some cases, the diseased plants are able to re-gain health, further grow and develop normally.
Is mosaic virus bad?
More than likely, it’s the result of a mosaic virus. Viruses cause many important plant diseases and are responsible for huge losses in crop production and quality in all parts of the world. There are over 2000 known viruses and about one-fourth cause disease in plants.
Can mosaic virus live in soil?
Unlike TMV (tobacco mosaic virus), CMV is not seedborne in tomato and does not persist in plant debris in the soil or on workers’ hands or clothing. The occurrence of this virus is erratic and unpredictable; consequently, control of this disease can be difficult.
Can humans get tobacco mosaic virus?
Tobacco mosaic virus (TMV), a widespread plant pathogen, is found in tobacco (including cigarettes and smokeless tobacco) as well as in many other plants. Plant viruses do not replicate or cause infection in humans or other mammals.
How do you test for tobacco mosaic virus?
Currently, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) are the most commonly used methods to detect TMV in plants2. However, the processes of those methods are quite time-consuming, complex, and even challenging since the TMV may distribute unevenly in plant tissues at low level.
