It is known to infect members of nine plant families, and at least 125 individual species, including tobacco, tomato, pepper (all members of the useful Solanaceae), cucumbers, and a number of ornamental flowers. There are many different strains.

Can plant viruses jump to humans?

Direct plant-to-human transmission This is a very rare and highly unlikely event as, to enter a cell and replicate, a virus must “bind to a receptor on its surface, and a plant virus would be highly unlikely to recognize a receptor on a human cell. One possibility is that the virus does not infect human cells directly.

Does mosaic virus stay in soil?

Tomato mosaic virus and tobacco mosaic virus can exist for two years in dry soil or leaf debris, but will only persist one month if soil is moist. The viruses can also survive in infected root debris in the soil for up to two years.

Does tobacco mosaic virus have an envelope?

The tobacco mosaic virus (TMV), a tobacco leaf pathogen, consists of a single-stranded RNA molecule containing 6395 nucleotides and enclosed by a protein envelope consisting of 2130 identical subunits (Fig. 3.7). Its replication is catalyzed by an RNA polymerase.

What plants can get mosaic virus?

Can a tobacco mosaic virus infect a human?

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.

Can plants carry human viruses?

It is currently considered that phytoviruses only infect plants and therefore, plant viruses cannot cause disease in humans.
