A pioneering study recently published in the esteemed scientific journal Nature introduces a cutting-edge technology known as Transposase-Assisted Target Site Integration (TATSI), specifically designed to revolutionize the efficiency of plant gene editing. The innovative method harnesses transposable elements to seamlessly integrate custom DNA into precise locations within plant genomes, ultimately striving to expedite the production of genetically enhanced crops in a more economical manner.
This groundbreaking research aims to address a prevalent challenge in crop improvement, which pertains to the inefficient and error-prone insertion of foreign DNA into plant genomes. While the CRISPR-Cas system can meticulously edit DNA, it encounters obstacles in accurately inserting custom DNA at these edited sites. To overcome this hurdle, the scientists amalgamated the precision of CRISPR-Cas with the innate capacity of transposable elements to act as a biological “glue,” thereby augmenting the rate of targeted DNA integration.
Dr. Keith Slotkin, a distinguished professor at the University of Missouri, Columbia, and his research team spearheaded this transformative project, leveraging transposable elements that constitute over 70% of the corn genome for crop enhancement. Supported by funding and investment from the Danforth Center US National Science Foundation (NSF), the project has yielded prototypes and advanced to the pre-commercial development stage. “Born out of the Big Ideas 2.0 competition, this project changed the course of the research we’re doing today and into the future. It is a real testament to the broader ‘focus-on-impact’ attitude of the Danforth Center,” expressed Dr. Slotkin.
For further insights, the press release from the Donald Danforth Plant Science Center elucidates the profound implications of the TATSI technology in the realm of plant gene editing.
