|Title: Method to Genetically Modify Castor Plants|
US Patent Office Full Record
ARS scientists have developed a method to genetically modify castor plants. The method allows for introducing new genetic material into the castor genome providing a means for genetically engineering castor plants. This invention may prove useful in developing safer castor plants, which could be used to provide a domestic castor oil source. The castor plant produces a bean containing castor oil. As a result of its unique chemistry, castor oil and products derived from it are useful for lubricants, paints and coatings, cosmetics, biodegradable plastics, anti-fungal components–about 300 products in total. The presence of a naturally occurring toxic protein, called ricin, and a highly allergenic storage protein greatly impede
The technology could be used by the oilseed processing industry. Companies that develop and manufacture biobased chemicals and fuels, and those involved in agricultural biotechnology and seed production would be able to use this technology.
