How Europe is Rethinking Plant Breeding Rules

Exploring the regulatory evolution of New Genomic Techniques and their potential to transform sustainable agriculture

A Genetic Crossroads

Imagine being able to develop crops that can withstand devastating diseases, thrive in drought-stricken soils, and require fewer pesticides—all through precise genetic adjustments that mimic natural processes.

This isn't science fiction; it's the promise of New Genomic Techniques (NGTs), revolutionary plant breeding methods that are forcing a dramatic rethink of European regulations originally designed for genetically modified organisms (GMOs). At the heart of this scientific and policy debate lies a pivotal legal opinion from the European Union's Court of Justice that suggested these techniques might not fit neatly into existing GMO frameworks. This article explores how this opinion has set the stage for a potential agricultural transformation that could reshape what grows on European farms for generations to come.

What Are New Genomic Techniques?

New Genomic Techniques (NGTs) are a suite of precision breeding methods that allow scientists to make targeted, specific changes to an organism's DNA. Unlike earlier genetic modification that often introduced DNA from unrelated species, many NGTs work by making subtle adjustments to a plant's existing genetic blueprint or by introducing genes from closely related, sexually compatible plants.

CRISPR-Cas9

The most famous of these techniques is CRISPR-Cas9, often described as "genetic scissors," which allows researchers to cut DNA at precise locations to delete, replace, or modify specific genes.

Other NGT Methods
  • Targeted mutagenesis: Creating precise changes at specific locations in the genome
  • Cisgenesis: Transferring genes between organisms that could conventionally breed
  • Intragenesis: Rearranging genetic elements within the same species

What makes NGTs revolutionary is their unprecedented precision, speed, and affordability compared to both conventional breeding (which relies on random genetic combinations) and earlier genetic modification techniques. While conventional breeding might take a decade to develop a new variety, NGTs can achieve more precise results in a fraction of the time 1 .

The New Regulatory Framework: Two Tracks for Innovation

The European Commission responded to this legal context with a landmark proposal in July 2023 that aims to create a modernized, two-track regulatory pathway for NGT plants 2 4 . This proposal represents the most significant potential overhaul of EU biotechnology regulations in decades.

Category 1 NGT Plants

Equivalent to conventional breeding methods. To qualify, plants must meet specific criteria:

  • Substitution or insertion of no more than 20 nucleotides
  • Deletion of any number of nucleotides
  • Targeted insertion of DNA sequences existing in the breeder's gene pool
  • The modifications must not interrupt an endogenous gene

These plants would be exempt from GMO requirements though their seeds would still require labeling, and they would be listed in a public database 5 .

Category 2 NGT Plants

Includes all other NGT plants that don't meet the equivalence criteria for Category 1.

These would remain subject to the full GMO framework, including:

  • Pre-market risk assessment
  • Authorization process
  • Traceability requirements
  • Labeling mandates

Comparison of Proposed NGT Categories in the EU

Feature Category 1 NGT Plants Category 2 NGT Plants
Definition Equivalent to conventional plants All other NGT plants
GMO Rules Exempted Subject to full GMO legislation
Risk Assessment Not required Required before authorization
Labeling Not required (except for seeds) Mandatory
Database Listed in public database Not applicable
Patent Transparency Must declare existing patents No additional requirements

The Patent Debate: Innovation Versus Access

One of the most contentious issues in the NGT discussion has been patent protection. In February 2024, the European Parliament surprised many by calling for a complete ban on patents for all NGT plants, arguing this would prevent "legal uncertainties, increased costs and new dependencies for farmers and breeders" 2 .

Council's Compromise Approach

The Council of the EU took a different approach in its March 2025 negotiating mandate, rejecting a full patent ban in favor of transparency mechanisms 5 . Under the Council's proposal:

  • Applicants must declare existing or pending patents when registering Category 1 NGT plants
  • Patent information would be included in a publicly accessible database
  • Voluntary declarations of willingness to license under equitable conditions are encouraged
  • An expert group would study patent impacts on innovation and access 5

This compromise aims to balance incentives for innovation (through patent protection) with ensuring that breeders and farmers maintain access to improved plant materials 2 .

Key Positions in the NGT Patent Debate

Institution Position on NGT Patenting Primary Concern
European Parliament Complete ban on all NGT plant patents Protecting farmers from dependencies
European Council Transparency instead of ban Balancing innovation with access
Industry Associations Opposed to patent ban Maintaining incentives for R&D investment
Seed Industry Supportive of Council's approach Ensuring continued innovation

Inside a Key Experiment: Developing Disease-Resistant Crops with CRISPR

To understand how NGTs work in practice, let's examine how researchers used CRISPR-Cas9 to develop powdery mildew-resistant wheat—a devastating fungal disease that typically requires frequent fungicide applications.

Methodology: Precision Gene Editing

Target Identification

Researchers identified the MLO gene which, when functional, makes wheat susceptible to powdery mildew.

Guide RNA Design

Scientists designed a specific guide RNA molecule that would lead the CRISPR-Cas9 system precisely to the MLO gene.

Plant Transformation

The CRISPR-Cas9 system was introduced into wheat cells using established transformation techniques.

Plant Regeneration

Transformed wheat cells were grown into complete plants using tissue culture methods.

Screening and Selection

Edited plants were screened to identify those with successful MLO gene mutations.

Results and Analysis

The experiment successfully generated wheat plants with specific mutations in the MLO gene that conferred strong resistance to powdery mildew. Unlike traditional breeding that might introduce hundreds of unknown genetic changes along with the desired trait, the CRISPR approach made precise changes only to the target gene.

Genetic Precision Comparison
CRISPR: 3-6 precise changes
Conventional: Thousands of unknown changes
Development Timeline
CRISPR: 2-3 years
Conventional: 8-10 years

Outcomes of MLO Gene Editing in Wheat

Parameter Conventional Wheat CRISPR-Edited Wheat
Powdery Mildew Susceptibility High Resistant
Genetic Changes Unknown thousands from breeding Precise modification of 3-6 MLO alleles
Development Time 8-10 years 2-3 years
Fungicide Requirements High Significantly reduced
Yield Impact Variable under disease pressure Stable under disease pressure

This case demonstrates how NGTs can achieve precise outcomes similar to what might occur through natural mutations or conventional breeding, but in a more targeted, efficient, and predictable manner.

The Scientist's Toolkit: Essential Reagents for NGT Research

Creating plants using New Genomic Techniques requires specialized biological tools and reagents. Here are the key components:

CRISPR-Cas9 System

The core gene-editing machinery consisting of the Cas9 enzyme that cuts DNA and guide RNA that directs it to specific sequences 7 .

Conclusion: Cultivating a Sustainable Future

The journey from the Advocate General's 2018 opinion to the current proposed NGT regulation illustrates how law and science must continually adapt to each other. The European Union stands at a crossroads, balancing the potential benefits of these technologies—climate resilience, reduced pesticide use, food security—with legitimate concerns about safety, corporate control, and consumer choice.

Potential Benefits
  • Climate-resilient crops
  • Reduced pesticide use
  • Enhanced food security
  • Precise genetic modifications
  • Faster development timelines
Key Concerns
  • Safety and environmental impact
  • Corporate control of seeds
  • Consumer acceptance
  • Patent and access issues
  • Regulatory oversight

As trilogue negotiations between the Commission, Parliament, and Council continue through 2025, the outcome will significantly influence not just European agriculture but global innovation in plant breeding 2 5 . What's clear is that the conversation has moved beyond simplistic GMO debates to more nuanced discussions about how to responsibly govern a new generation of breeding techniques that offer unprecedented precision and potential.

The future of what we grow and eat in Europe may depend on getting this balance right—fostering innovation while maintaining trust and safety. As these discussions continue, they represent a fascinating case study in how society navigates the challenges and opportunities of technological progress in our most fundamental human endeavor: producing food.
