This project aims to transform our understanding of symbiotic nitrogen fixation in legume root nodules. Root nodulation sustainably fixes sizeable amounts of nitrogen to boost crop production worldwide yet its utilisation is waning in favour of using nitrogen fertilisers. The project applies cutting-edge tools to define how two hormone systems boost and limit nitrogen fixation, respectively. The project expects to reveal ways to reconfigure these hormone outputs to improve nodule number and the efficacy of nitrogen fixation. The findings will benefit agriculture by reducing the reliance on costly nitrogen fertilisers, thus mitigating the huge environmental damage they cause, and will provide more sustainable ways to ensure food security.

该项目旨在改变我们对豆科植物根瘤共生固氮的理解。根结瘤可持续地固定大量氮，以提高全球作物产量，但其利用率正在下降，有利于使用氮肥。该项目应用尖端工具来定义两种激素系统如何分别促进和限制固氮。该项目期望揭示重新配置这些激素输出的方法，以提高根瘤数量和固氮效率。这些发现将通过减少对昂贵氮肥的依赖而使农业受益，从而减轻其造成的巨大环境破坏，并将提供更可持续的方法来确保粮食安全。
