This project aims to transform our understanding of the relationship between nutrient availability and plant defence. Plant defences are activated by responses to cell wall damage, caused by pathogens. My preliminary data uncovered that the response to cell wall damage depends on the nitrogen status of the plant; providing a direct link between nutrients and defence. The research will use new mutants that disengage this link to uncover molecular mechanisms underlying this process. The outcomes will provide new approaches to breed crop plants with improved nitrogen use efficiency and disease resistance. It will benefit agriculture by reducing the use of costly fertilisers and pesticides and mitigate the huge environmental damage they cause.

该项目旨在改变我们对养分可用性和植物防御之间关系的理解。植物防御是通过对病原体引起的细胞壁损伤的反应来激活的。我的初步数据发现，对细胞壁损伤的反应取决于植物的氮素状况;提供了营养和防御之间的直接联系。这项研究将使用新的突变体来解开这一联系，以揭示这一过程背后的分子机制。这些结果将为培育具有提高的氮利用效率和抗病性的作物提供新的方法。它将通过减少昂贵的化肥和杀虫剂的使用，减轻它们对环境造成的巨大破坏，使农业受益。
