Virus resistant plant cells

In summary, virus resistant plant cells are genetically modified cells that are able to resist and fight against specific viruses. They are created through genetic engineering techniques and offer the benefit of protecting crops from viral diseases. These cells have been extensively tested and approved as safe for consumption and do not have negative impacts on the environment.

My Bio textbook says that, by introducing the virus coat protein gene into a plant cell the cell becomes virus resistant. How is that possible?

For tobacco mosaic virus - this paper explains results:

In this case, the presence of some variants of the coat protein inhibit the production/effectiveness of the MP - mobilization protein - which in turn slows down the transmission of the virus from cell to cell.

The introduction of the virus coat protein gene into a plant cell allows the cell to produce the virus coat protein. This protein is a key component of the virus's structure and is essential for the virus to infect and replicate within a plant cell. By producing the virus coat protein, the plant cell is essentially mimicking the appearance of an already infected cell, tricking the virus into thinking it has already successfully invaded the cell. As a result, the virus is unable to infect the cell and replicate, making the plant cell resistant to the virus. This process is known as "gene silencing" and is a natural defense mechanism of plants against viruses.
 

1. What are virus resistant plant cells?

Virus resistant plant cells refer to plant cells that have been genetically modified to be able to resist and fight against specific viruses.

2. How are virus resistant plant cells created?

Virus resistant plant cells are created through genetic engineering techniques, where specific genes from other organisms are inserted into the plant's genome to provide resistance against viruses.

3. What are the benefits of virus resistant plant cells?

The main benefit of virus resistant plant cells is that they can protect crops from devastating viral diseases, leading to increased crop yield and improved food security.

4. Are virus resistant plant cells safe for consumption?

Yes, virus resistant plant cells have been extensively tested and approved by regulatory agencies to be safe for consumption. The genetic modification does not introduce any harmful substances into the plant.

5. Can virus resistant plant cells become harmful to the environment?

No, virus resistant plant cells have been shown to have no negative impact on the environment. They are designed to target specific viruses and do not harm beneficial insects or other organisms in the ecosystem.
