It could lead to crops that are more nutritious, drought-resistant, or disease-proof — directly affecting the quality and availability of the food on your plate.
Think of a plant's DNA like a very long instruction manual. Until now, scientists could make small edits easily, but inserting a whole new chapter was messy and imprecise. PrimeRoot is like a highly accurate 'cut and paste' tool that can slot in large, complex instructions exactly where needed — making it much easier to give plants new and useful traits. This could speed up the development of better crops and plants engineered to help the environment.
Key Findings
PrimeRoot can insert DNA fragments of up to 11.1 kilobases (kb) into plant genomes, far exceeding the capacity of earlier gene-editing methods.
The system combines improved guide RNA designs, enhanced plant prime editor proteins, and advanced recombinases to achieve precise, targeted large-DNA insertion.
Third-generation PrimeRoot editors further boosted precision and efficiency across multiple gene delivery methods and plant species.
chevron_right Technical Summary
Scientists have developed PrimeRoot, an advanced gene-editing tool that can insert large pieces of DNA — up to 11,100 base pairs — into plant genomes with high precision. This breakthrough addresses a major bottleneck in plant engineering, opening the door to more ambitious crop improvements.
