XERICO drought tolerance technology for enhanced crop resilience

Overview

XERICO drought tolerance technology represents a significant advancement in agricultural biotechnology, aimed at protecting crops from the adverse effects of drought by leveraging the plant's natural defense mechanisms. By overexpressing the XERICO gene, the technology promotes stomatal closure during drought conditions, thereby reducing transpirational water loss without affecting plant growth. This innovative approach has been validated in corn and potato, demonstrating increased yield and starch content, making it a promising solution for enhancing crop resilience.

Technical specifications

Key features of XERICO technology include:

• Intragenic modification: Utilizes plant-derived XERICO gene, offering a publicly acceptable alternative to inter-kingdom DNA transfers.
• Drought-specific expression: Activates only during drought conditions to prevent unintended growth penalties.
• Field-tested efficacy: Proven in major crops like corn, poplar, potato, and rice, with commercial licensing in the potato industry.
• Genetic background compatibility: Tested in clean genetic backgrounds for effective field performance.

Technology readiness level

The XERICO technology is at a Technology Readiness Level (TRL) 6, indicating a high degree of maturity with validation in relevant environments. Further field tests are planned to mitigate technical risks and confirm efficacy under diverse conditions, paving the way for broader commercial deployment.
