Boosting technology for enhanced pepper resistance to bacterial leaf spot

Overview

Resurrect Bio's Boosting technology is a cutting-edge gene editing solution designed to enhance the immune response of pepper plants against a broad spectrum of pathogens, with a primary focus on Xanthomonas euvesicatoria, the causative agent of bacterial leaf spot. By employing innovative modifications to NLR (nucleotide-binding domain leucine-rich repeat) immune receptors, this technology strengthens the plant's natural defense mechanisms, resulting in healthier crops and reduced reliance on chemical inputs.

Technical specifications

Key features:

• Enhanced Bs2 sensor response: The Bs2 sensor detects X. euvesicatoria, and Boosting technology amplifies this pathway, providing robust immunity.
• Stronger immune hubs: By fortifying NRCs (NLRs Required for Cell death), the technology enhances the response to various pathogens, including bacteria, oomycetes, and viruses.
• Minimal amino acid changes: This approach allows for the easy stacking of additional desirable traits.
• Reduced inputs: Improved crop health translates into less need for chemical treatments and more efficient land use.

Technology readiness level

Currently at Technology Readiness Level 5, Resurrect Bio's Boosting technology has been validated in controlled environments using transient expression systems. The next steps include genome analysis, application of boost edits, and in-plant validation, followed by an industry partner conducting genetic engineering and field trials to develop a commercially viable, disease-resistant pepper variety.
