Corn is another genetically altered crop. It does not have as many new genes transferred into it as potatoes do. Corn receives a new gene from wheat, which helps reduce insect damage. It also gets a gene from the Firefly, which gave rise to the introduction of marker genes. Finally corn contains a gene from bacteria that increases habitat tolerance.
Tomatoes are another crop that carry genetically altered genes.
The Flounder gene, for example, reduces damage to this crop by increasing the tomatoes to freezing. Another gene that affects tomatoes comes from a virus that encourages resistance to disease. Finally like in corn and potatoes above, tomato plants contain a bacteria gene, which reduces the damage that insects can do to tomato plants. Another crop that has been altered by the transferring of other organisms is rice. Rice contains a gene from beans or peas.
