  • Patent number: 10982219
    Abstract: Altered guayule that produce more rubber than the amount of rubber produced by non-altered guayule are provided. The alterations may include (i) a reduction in amount of functional PaAos produced by the altered guayule, (ii) an increase in amount of a transcription factor produced by the altered guayule, (iii) an increase in amount of salicylic acid within the altered guayule, (iv) exposure of the altered guayule to cold temperature, and (v) a combination thereof. Methods of producing the altered guayule and methods of increasing the amount of rubber produced by a guayule are also provided.
    Type: Grant
    Filed: May 10, 2018
    Date of Patent: April 20, 2021
    Assignee: The United States of America, as represented by the Secretary of Agriculture
    Inventors: Colleen M. McMahan, Maureen C. Whalen, Dante Placido, Niu Dong
  • Patent number: 10961541
    Abstract: Genetically altered guayule are generated which produce more rubber than the amount of rubber produced by a wild-type guayule. The genetically altered guayule plant contains an expression vector that encodes a protein involved in rubber production. Method of making and using the genetically altered guayule are included.

  • Publication number: 20180327770
    Abstract: A reduction in the amount of functional PaAos in guayule results in the production of increased amounts rubber compared to the amount of rubber produced by wild-type guayule having a non-reduced amount of functional PaAos. Further, the guayule with reduced amount of functional PaAos are larger than wild-type guayule and thus have larger rubber yield per acre than wild-type guayule. Reduction of the amount of functional PaAos in guayule can be caused by genetic alterations in PaAos. Guayule having PaAos with a specific amino acid sequence produces more rubber than guayule with PaAos having a different amino acid sequence. Thus, one can use the sequence differences as a biomarker for selecting high rubber producing guayule plants.

  • Patent number: 9251924
    Abstract: Processes for the preparation of elastomeric conductive material, involving combining at least one conductive polymer with rubber latex, at least one organic acid, at least one oxidant, a pH stabilizer, optionally an organic solvent, and optionally at least one surfactant. Also disclosed are elastomeric conductive materials produced by such processes, which exhibit excellent strength, elasticity, and conductivity.
