Pennycress domestication platform
Illinois State University researchers have developed a CRISPR-based platform to domesticate wild pennycress into a profitable winter annual oilseed cash cover crop. This technology improves seed quality, eliminates weediness, and optimizes oil profiles, enabling the crop to be integrated into existing corn-soybean rotations. It offers farmers a new revenue stream while providing environmental benefits, including reduced soil erosion and nutrient runoff, and supplies a sustainable feedstock for biofuel, animal feed, and industrial applications.
Overview
The pennycress domestication platform leverages CRISPR-Cas9 genome editing to transform wild Thlaspi arvense, commonly known as pennycress, into a high-yielding, profitable winter annual oilseed cash cover crop. Traditionally considered a weed, this plant has been genetically re-engineered to eliminate undesirable traits while retaining its natural hardiness. The platform offers a sustainable solution for agricultural land that typically lies fallow during winter months in the U.S. Corn Belt, providing farmers with a revenue-generating crop that simultaneously delivers ecosystem services such as reduced soil erosion and nutrient runoff.
Technical specifications
The platform utilizes advanced gene-editing techniques to optimize key agronomic and seed quality characteristics:
- Trait improvements: Successful reduction of seed dormancy, improved crop stand establishment, and elimination of pod shatter to ensure reliable harvests.
- Enhanced chemical profiles: Multiplex CRISPR-Cas9 mutations have been used to significantly reduce glucosinolate content, making the seed meal safe and palatable for animal feed.
- Optimized oil composition: Targeted genetic modification of lipid biosynthetic pathways to increase oleic acid content, improving the oil's oxidative stability and cold-flow properties for biofuel and industrial applications.
- Compatibility: Designed as a winter cover crop that fits seamlessly into existing corn-soybean rotation systems without displacing primary food crops.
Technology readiness level
The technology is at TRL 8. The research team has successfully demonstrated the domestication of pennycress through CRISPR-Cas9, documented in peer-reviewed journals such as Nature Plants. The initiative has progressed through multi-state field trials, extensive genetic validation, and collaborative efforts involving academic and industry partners to develop supply chain infrastructure for commercial launch.
