Future-proofing agriculture: scientists look to biotechnology to improve crop resilience and nutritional value
Funded by a £8.5M grant from the UK Government’s Advanced Research and Invention Agency (ARIA), the researchers will leverage advances in engineering biology to establish synthetic plant chromosome (synPAC) technologies. These technologies promise to provide powerful new ways of introducing novel traits to plants —such as producing essential nutrients or increased pest resistance—while maintaining the plant’s existing characteristics.Learning from nature: improving crops for people and the planetModern agriculture faces significant challenges, from climate change to soil degradation and food security concerns. However, traditional plant breeding and selection can take decades to introduce beneficial traits, relying on random genetic mixing over multiple generations.This project will develop synPACs, a novel system for rapidly designing and delivering beneficial traits to plants. Building on natural processes, synPACs enable researchers to rapidly introduce multi-gene traits in a far more precise, controllable, and predictable fashion — offering an innovative alternative to conventional breeding methods.To achieve this, scientists at The University of Manchester will develop unique new technologies that will allow crop scientists to design and build chromosomes carrying desired traits. synPACs will use Saccharomyces cerevisiae (common baker’s yeast) as a DNA assembly line to efficiently assemble large segments of plant DNA into synthetic chromosomes, prior to direct transfer to crop plants using highly efficient methods developed at the John Innes Centre, and characterised at the Earlham Institute.The Earlham Institute will lead on three areas of the project; potato tissue atlas and regulatory element discovery, assembly and testing of a potato regulatory element library through the Earlham Biofoundry, and engineering synPAC components and synPAC maintenance.The first phase of the project will focus on potatoes, a globally important crop, with the goal of developing technology pipelines to fast-track plant engineering. Initial target traits will include enhanced nutritional content and resilience against environmental stressors, as well as improving agricultural sustainability by reducing reliance on chemical inputs while improving crop yields. By enabling plants to efficiently produce valuable compounds, synPACs could also support the development of new, plant-based sources of essential nutrients and bioactive compounds, benefiting both human health and the environment.Ensuring stability, safety and ethicsThe synPAC initiative is committed to working transparently with industry partners, regulators, and the public to ensure responsible development and application of this technology. The research team is focused on delivering benefits for both farmers and consumers, ensuring that crops developed through this platform align with the highest standards of safety, sustainability, and societal acceptance. The synPAC team will work closely with social science teams also funded by ARIA to explore these critical issues.With a clear roadmap for Phase Two, the synPAC team aims to expand this technology to other staple crops, ultimately ushering in a new age of crops optimised for climate resilience, nutrition, and sustainability.
