UK grants first regulatory approval to a CRISPR-edited crop
The United Kingdom has issued its first regulatory approval for a CRISPR-edited crop under its new precision-breeding rules. The decision covers a Rothamsted Research barley line with higher lipid content that could improve forage value and help cut methane emissions from ruminants.
The United Kingdom has issued the first regulatory approval for a gene-edited crop under its new precision-breeding rules. Nature Biotechnology reports that the decision is the first concrete regulatory outcome under the UK’s updated framework for plant gene editing and marks a policy shift away from the more restrictive European Union approach to genetically modified organisms. For agricultural policy, that makes the approval more than a scientific milestone: it is an early test of how the new rulebook will operate in practice.
The approval concerns a barley line developed by Rothamsted Research in Harpenden, England. According to Nature Biotechnology, the crop was edited with CRISPR to raise lipid content in the plant’s tissues. That matters because higher lipid levels in forage can increase the energy value of feed for ruminant livestock such as cattle and sheep, and they also have the potential to reduce methane emissions generated during digestion.
Under the UK’s new system, gene editing and other precision-targeted methods are treated as lower risk than plant modification involving foreign DNA. If the technique introduces a trait that is indistinguishable from changes that could arise naturally or through conventional breeding, the resulting product can move forward with minimal oversight. That is the regulatory logic behind this first approval, and it creates a more flexible pathway for research institutes and developers seeking to move useful agronomic traits toward field evaluation and eventual commercial use.
Nature Biotechnology says the Rothamsted team achieved the trait by disrupting two genes, SDP1A and SDP1B, which encode triacylglycerol lipases that normally break down plant oils. By reducing that breakdown, the barley accumulates more lipids. Rothamsted Research has also said the crop is being taken forward through the PROBITY initiative, where precision-bred plants are assessed in practical farming conditions with researchers, farmers and supply-chain partners involved in the testing process.
For agriculture, the importance of the decision is twofold. At the crop level, it advances a forage trait that could improve feed efficiency and support methane reduction in livestock systems. At the regulatory level, it signals that England is building a more permissive environment for gene-edited crops with direct farm use cases. If field and production assessments confirm the expected performance, the approval could help accelerate later projects aimed at grain quality, yield, feed efficiency and broader agricultural resilience.
