Cucurbits protoplast regeneration and gene editing using ARCUS nuclease

Overview

Elo Health is pioneering a protoplast regeneration system tailored for high-value cucurbit crops such as melons. This innovative approach leverages the proprietary ARCUS nuclease for precise gene editing. By expediting trait integration and reducing development costs, this technology aims to significantly enhance the commercial viability and regulatory efficiency of gene editing in cucurbits. The initiative builds on Elo's extensive experience in protoplast regeneration across various crop families, offering a TDNA-free editing process that allows for precise selection of desired genetic traits from single cells.

Technical specifications

• Protoplast regeneration system: Designed specifically for cucurbit crops, enabling precise gene editing.
• ARCUS nuclease: A proprietary tool used for efficient and accurate gene editing.
• Broad applicability: Builds on experience with other crop families like spinach, lettuce, and watermelon.
• Stepwise approach: Involves validation of the watermelon protoplast method, selection of ARCUS nucleases, and phased greenhouse growout and phenotyping.
• Cost efficiency: Reduces development costs by enabling selection from single cells.

Technology readiness level

This technology is currently at TRL 4, indicating that it has been validated in a laboratory setting and is ready for further development and testing in relevant environments. Future validation plans include collaboration with seed-industry partners to apply known gene-editing strategies within commercial germplasm.
