Disease resistance refers to the ability of a plant or animal to limit or prevent infection by a pathogen such as a virus, bacteria, or fungus. Organisms have developed complex immune systems over evolution to recognize these pathogens as foreign, and initiate defenses to destroy them or limit their growth and spread.
In plants, disease resistance works through similar mechanisms. When a plant recognizes a pathogen trying to infect it, it triggers hypersensitive reactions at the infection site, sending signals to surrounding cells to build physical and chemical barriers. Plants also produce antimicrobial compounds and proteins that directly attack the pathogens. Some plants have R genes which recognize specific pathogens and rapidly activate defenses against that disease.
Selective breeding and biotechnology have been used to introduce disease resistance traits into crops, helping to secure food production. For example, the Rainbow papaya was genetically engineered to be resistant to papaya ringspot virus, saving the Hawaiian papaya industry. Other disease resistant crops include wheat resistant to stem rust, and corn with resistance to northern corn leaf blight.

Benefits of disease resistance
There are many benefits to developing disease resistant crops and medicines:
Controversies
However, the genetic engineering of disease resistance has also been controversial. There are concerns about:
More research is still needed to weigh risks versus benefits. Strict regulatory systems help manage the testing and release of GM crops.
