First European Field Trial of Gene-Edited Wheat Underway

News EditorBy News EditorApril 18, 2025 Europe News 8 Mins Read

In 2020, scientists Emmanuelle Charpentier and Jennifer Doudna were awarded the Nobel Prize in Chemistry for their groundbreaking work on CRISPR-Cas, a powerful gene-editing technology with vast potential applications in fields like agriculture and medicine. This emerging innovation is part of a broader category known as new genomic techniques (NGTs), which promise to revolutionize genetic modifications without introducing foreign DNA. As Europe embarks on its first large-scale gene-edited wheat trial, there are growing discussions about the implications of NGTs and their regulation within the EU framework.

Understanding New Genomic Techniques (NGTs)

New genomic techniques (NGTs), which include methods like CRISPR-Cas, offer a way to make precise alterations in an organism’s genetic makeup. Unlike traditional genetically modified organisms (GMOs), NGTs do not involve the introduction of foreign DNA from sexually incompatible species. Instead, they operate by making small modifications that can enhance certain traits within a species. This enables scientists to create crops with desirable features, such as improved nutritional profiles or enhanced resistance to pests and diseases.

Despite their potential, the European Union has not yet implemented a formal regulatory framework specific to NGTs as of 2023. As a result, the scientific community continues to discuss and formulate definitions and classifications for these techniques. For instance, experts like Vittoria Brambilla, an associate professor in botany at the University of Milan, describes NGTs as organisms that contain only small modifications to their existing genes rather than foreign genetic material. Thus, they are positioned as a more targeted approach to genetic improvement in contrast to the broader methodologies characteristic of GMOs.

The implications of NGTs extend significantly into both agriculture and the pharmaceutical industries. For example, NGTs may allow for the production of crops that require fewer pesticides or are more resilient to extreme weather conditions, thereby addressing key issues related to food security. However, the exact distinctions between NGTs and GMOs are still a topic of debate, further complicating the discussions surrounding legislation and public perception.

The Pioneer Wheat Research Near London

In a notable advancement for agricultural science, a team at Rothamsted Research in Harpenden, near London, is pioneering Europe’s first field trial of gene-edited wheat. This project, initiated in 2016 shortly after Brexit, employs the CRISPR-Cas9 technology to reduce the levels of asparagine in wheat. Asparagine, an amino acid that can convert into acrylamide during cooking, poses potential health risks, including cancer. Thus, the reduction of this compound in foodstuffs serves both public health and safety interests, showcasing the real-world applications of NGTs.

The experiment led by Nigel Halford has shown positive results, achieving significant reductions in the concentration of free asparagine down to 10 percent of control levels. This achievement highlights the effectiveness of CRISPR-Cas9 as a tool in creating genetically improved crops. Interestingly, the method used in this trial was a deviation from conventional practices; researchers first integrated genetic material encoding Cas9 and guide RNA directly into the wheat. Although this categorizes the plant initially as a GMO, the project aims to breed out these components, ultimately yielding a genome-edited plant that aligns with NGT classifications.

While the initiative represents a tremendous leap forward for agricultural practices, it also faces technical challenges, particularly in ensuring that all cells within the plant exhibit the same genetic modification. As noted by researcher Ania Lukasiewicz, synchronization in genetic alterations can be complex due to the regenerative capabilities of plants. Moving forward, Rothamsted Research is refining its methodologies, indicating ongoing commitment to advancing this crucial work.

Current EU Regulations on NGTs

Presently, the European Union regulates NGTs under existing GMO legislation, which enforces rigorous testing and risk assessments prior to commercialisation. This regulatory landscape has fostered rigorous scrutiny of NGT applications and slowed the process of bringing these innovations to market. However, the European Commission has proposed a new framework in 2023 aimed at distinguishing between different categories of NGT products to facilitate a more streamlined regulatory process.

Under the proposed changes, NGTs would be classified into two primary categories: NGT 1, which would exempt certain products from stringent risk assessments and labelling requirements, and NGT 2, which would still fall under traditional GMO regulatory frameworks. This dual classification emphasizes the type and number of genetic modifications permissible, with NGT 1 allowing only specific, minimal changes to the organism’s genetic blueprint, while NGT 2 encompasses a broader range of alterations.

This evolving regulatory approach has generated a mix of optimism and uncertainty among stakeholders involved in genetic research, agriculture, and food production. For scientists working in gene editing, the proposal suggests a potentially expedited path to market, raising hopes of faster integration of beneficial crops. However, the intricacies of implementing such a framework remain a critical talking point as further discussions take place within the EU.

Controversy Surrounding NGT Regulations

Despite the optimism among certain sectors of the scientific community, skepticism persists regarding the proposed EU regulations on NGTs. Prominent figures, such as Katja Tielbörger, a professor of plant ecology at the University of Tübingen in Germany, argue against the proposed regulatory dichotomy. Her concerns primarily focus on the environmental implications and agricultural ramifications of introducing new plant varieties, especially given the complex interplay within ecosystems.

Tielbörger emphasizes that scientific evidence does not fully support the distinction between NGT 1 and NGT 2, suggesting that the proposed limits appear arbitrary. Furthermore, she presents a critical perspective on whether the introduction of new NGTs is genuinely necessary to address food security issues. According to her, the real focus should not be on developing new genetic strains but on how food is allocated and distributed effectively, stating, “Food security is not an issue of which varieties we have. It’s an issue of how the food is distributed and what is happening with it.”

Such concerns underscore the need for a balanced approach to the regulation and implementation of NGTs in agriculture, reflecting wider societal values and ecological considerations.

The Future of NGTs in Agriculture

Looking ahead, the future of NGTs in agriculture appears promising yet fraught with challenges. As new regulations emerge, there will be critical discussions about how they will impact public perception and acceptance of genetically edited crops. The advances made in gene-editing technologies like CRISPR-Cas could unlock avenues for creating more resilient agricultural products capable of thriving in changing climates and meeting the challenges posed by diminishing natural resources.

Rather than simply debating the safety and efficacy of NGTs, proponents advocate for a broader conversation about their role in sustainable agriculture and food security. As stakeholders from academia, industry, and regulatory bodies navigate the complexities of this emerging landscape, a collaborative approach will be essential for harnessing the full potential of NGTs while addressing legitimate concerns from various sectors.

In summary, the gradual evolution of NGT regulations will significantly shape the trajectory of agricultural science and food production within Europe and beyond, emphasizing the importance of ongoing dialogue and research.
