What does brome mosaic virus do?

Brome mosaic virus (BMV) is a positive-strand RNA virus that infects cereal plants, causing mosaic symptoms and stunting. BMV is the type member of the genus Bromovirus in the family Bromoviridae.

What are the symptoms of brome mosaic virus?

How do plants fight viruses?

Plants use RNA-silencing mechanism and produce short interfering RNA (SiRNA) molecules in a defense response against viral infection. To counter this defense response, virus produces suppressor proteins that can block the host silencing pathway or interfere with its function in plant cells [6].

Can plant viruses infect human?

It is currently accepted that a strict separation exists between plant and vertebrate viruses regarding their host range and pathogenicity, and plant viruses are believed to infect only plants. Accordingly, plant viruses are not considered to present potential pathogenicity to humans and other vertebrates.

What is Mosaic Virus plants?

A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.

Can you eat a papaya with ringspot virus?

It is important to note that humans have been eating PRSV-infected papaya fruits for many years and these fruits have higher concentrations of the virus coat protein than what is expressed in the transgenic papaya. There has been no evidence of adverse effects linked to the consumption of virus infected fruit.
