Fungal disease management will become increasingly important for global food security in the coming years, especially in the face of climate change and increasing food demand. The development of disease resistant crops to fungal infection is central to this solution, so knowledge of the plant's immune response to fungal infection is essential for the development of crops with enhanced resistance. This thesis studies CERK1, the main pattern recognition receptor protein for chitin in plants, and it's interaction with SUMO during chitin elicitation. Additionally, the SUMO protease DeSi3a and its role during botrytis cinerea infection is explored. The working hypotheses for this study are that like FLS2, CERK1 is SUMOylated upon chitin elicitation and that this post-translational modification is essential for the activation of fungal immune signaling in the cell.

真菌病管理在未来几年对全球粮食安全将变得越来越重要，特别是在面对气候变化和日益增长的粮食需求的情况下。开发抗真菌感染的抗病作物是这一解决方案的核心，因此了解植物对真菌感染的免疫反应对于开发具有增强抗性的作物是至关重要的。本论文研究了植物中甲壳素的主要模式识别受体蛋白CERK1及其在甲壳素诱导过程中与相扑的相互作用。此外，还探讨了相扑蛋白水解酶DeSi3a及其在灰霉病菌侵染过程中的作用。本研究的工作假设是，像Fls2一样，CERK1在甲壳素诱导下被Sumoyl化，这种翻译后修饰对于激活细胞中的真菌免疫信号是必不可少的。
