The Need

In today's global landscape, the demand for sustainable and renewable sources of rubber has never been more pressing. With traditional rubber tree cultivation facing challenges such as limited land availability and susceptibility to diseases, there's an urgent need for alternative sources of natural rubber. Meeting this need requires innovative solutions that not only offer a viable alternative but also ensure scalability and environmental sustainability.

The Technology

Our groundbreaking technology focuses on the commercial development of Taraxacum kok-saghyz, a diploid (2n) small rubber-producing dandelion species. Leveraging polyploidy techniques commonly used in various crop species, we have optimized the experimental conditions necessary to produce tetraploid (4n) Taraxacum kok-saghyz plants from seed using colchicine. With 19 distinct 4n lines developed thus far, our technology demonstrates increased root rubber concentration compared to diploid plants. Furthermore, we've showcased the fertility of tetraploids, enabling interbreeding to produce viable tetraploid seed.

Commercial Applications

  • Natural rubber production for various industries including automotive, medical, and consumer goods.
  • Sustainable agricultural practices for rubber cultivation, reducing reliance on traditional rubber tree plantations.
  • Biotechnological advancements in plant breeding and genetic engineering for enhanced crop traits.

Benefits/Advantages

  • Enhanced rubber yield and quality compared to traditional rubber sources.
  • Reduced environmental impact through sustainable agricultural practices and decreased reliance on deforestation.
  • Increased resilience to diseases and environmental stressors, ensuring a more stable and reliable rubber supply chain.
