Guayule is a perennial shrub, native to the desert of northcentral Mexico and southwestern Texas, which produces high quality natural rubber that is suitable for use in passenger and commercial-grade tires . The plant produces latex that is hypoallergenic, particularly desirable in the medical device market, and resin that can be used in a variety of industrial products such as adhesives and coatings. The primary parts of the guayule plant of economic interest are in the parenchyma tissues of the stems and roots where the majority of the rubber particles accumulate. |
