NRC4 gene editing for broad-spectrum disease resistance in tomatoes
BetterSeeds' NRC4 gene editing technology enhances disease resistance in tomatoes, providing protection against fungi, bacteria, and pests without affecting growth or yield. The solution is scalable, adaptable, and commercially ready for integration into various crops.
Overview
BetterSeeds' NRC4 gene editing technology offers a groundbreaking approach to enhancing disease resistance in tomatoes. By modifying the NRC4 gene, this solution triggers a gain-of-function phenotype, providing broad-spectrum resistance against pathogens such as Botrytis cinerea and Xanthomonas spp., as well as pests like Helicoverpa armigera, whiteflies, and spider mites. This innovation is crucial for reducing significant yield and quality losses caused by these challenges, which are difficult to control with traditional chemicals. The NRC4 technology complements existing crop protection strategies and is ready for commercial application.
Technical specifications
- Genetic Modification: The NRC4 gene is edited to enhance immune responses, resulting in strong resistance to multiple pathogens and pests.
- Pathogen and Pest Resistance: Effective against gray mold, bacterial leaf spot, and various insect pests without compromising plant growth or yield.
- Commercial Readiness: Gene edits have been successfully completed in tomatoes, with potential expansion to other solanaceous crops and vegetables.
- Scalability and Adaptability: The technology can be integrated into elite tomato parental lines and other crop species, offering a versatile solution for improving crop resilience.
Technology readiness level
The NRC4 gene editing technology is currently at Technology Readiness Level 5. It has undergone successful validation in controlled environments and is set to enter multi-location field trials to further assess its effectiveness. Future plans include regulatory compliance, commercialization, and exploration of its applicability to other crops.
About BetterSeeds
BetterSeeds is an agricultural biotechnology company that provides a comprehensive gene-editing platform designed to democratize access to advanced plant breeding technologies. The company’s integrated framework combines gene-editing tools, specialized delivery systems, and non-transgenic trait modules. By utilizing technologies such as CRISPR-Cas9, BetterSeeds enables seed companies that lack the infrastructure to build in-house gene-editing stacks to develop new crop varieties with enhanced properties, including resistance to climate stressors and adaptability to mechanized harvesting.
The company serves the broader seed industry by offering a scalable, affordable alternative to traditional, high-cost R&D models historically dominated by a few major players. By facilitating the development of elite traits without the introduction of foreign genes, BetterSeeds helps its partners accelerate breeding programs and transition from initial pilots to repeatable, commercial deployments. The company’s approach is supported by a portfolio of subsidiaries that demonstrate the versatility of its platform across various high-value specialty crops.
