Crispr/cas9 gene editing for powdery mildew resistance in garden peas
This solution utilizes CRISPR/Cas9 gene editing to knock out the PsMLO1 gene in garden peas, conferring resistance to powdery mildew by preventing pathogen colonization.
Overview
This innovative solution employs CRISPR/Cas9 gene editing technology to enhance powdery mildew resistance in garden peas. By specifically targeting and knocking out the PsMLO1 gene, which is a known susceptibility factor for powdery mildew, this approach aims to prevent the pathogen Erysiphe pisi from colonizing the plant's epidermal cells. This genetic modification could lead to more resilient pea crops, reducing losses from disease and decreasing the need for chemical fungicides.
Technical specifications
Key features:
- Gene Targeting: PsMLO1 gene identified for knockout to confer mildew resistance.
- Guide RNAs (gRNAs): Designed for precise CRISPR/Cas9 targeting.
- Transformation: Agrobacterium-mediated delivery of CRISPR constructs into pea cells.
- Molecular Screening: PCR and sequencing to confirm gene edits.
- Phenotypic Evaluation: Assess resistance levels in edited plants.
- Genotypic Analysis: Ensure stability of edits across generations.
- Field Trials: Evaluate agronomic performance and disease resistance in real-world conditions.
Technology readiness level
This technology is currently at TRL 3, indicating experimental proof of concept. Initial gene targeting and protocol optimization have been completed, with further steps required for regulatory approval, molecular screening, and field trials to fully validate the solution's effectiveness in conferring disease resistance.
About ANSES
ANSES is France’s national public scientific and technical establishment for food, environmental and occupational health and safety, operating a nationwide network of nine laboratories across 16 sites coordinated from Maisons‑Alfort. Its co‑located reference laboratories provide accredited testing, surveillance data, and access to expert risk assessment, while proximity to production regions enables rapid field‑to‑lab response. ANMV, the veterinary medicinal products authority embedded within ANSES, together with ANSES registers for biocides and plant‑protection products, creates a unified interface for R&D teams navigating evaluation and market authorization. Research is primarily supported by the French government and augmented by competitive European programs, including Horizon Europe initiatives that ANSES coordinates and participates in. Formal collaboration with EU bodies and a confidentiality framework with the U.S. FDA further streamline regulatory engagement.
