PCR and agriculture

Some bacteria contain genes for an insecticide. This bacterium insecticide can be selected, amplified, and inserted into the DNA of many plants to resist caterpillars and other pests.

An example of biotechnology at work in agriculture is the rot-resistant tomato. The DNA in the tomato plant was altered by adding a gene that produces an antisense molecule. The antisense molecule inhibits the tomato from producing the enzyme responsible for rotting, enabling the tomato to ripen for a longer period of time on the vine.
