Docket Number: 2198
Serial Number: 9522401
Date Patented: 03/09/2004

Technology Description:

Agricultural Research Service scientists are producing plants that have enhanced disease-fighting power. Plants naturally produce hydrogen peroxide in response to microbial invasion. Hydrogen peroxide possesses moderate antimicrobial activity. This invention provides a method of making pathogen-resistant plants by modifying the plants with a gene, called chroloperoxidase, from a naturally-occurring bacteria that boosts the plants ability to fight microbial pathogens. Presence of the chloroperoxidase gene results in more than a 100-fold increase in a plant's ability to fight lethal microbes. By developing plants with built-in disease protection, this invention could ultimately lead to a reduced-reliance on chemical pesticides. This invention could be used to transform a variety of plants and crops, including those for food use.


Please refer to USPN 6,703,540 (Docket #0021.98), "Transformation of Plants with a Non-Heme Chloroperoxidase Gene to Enhance Disease Resistance, which issued on March 9, 2004.
