9411951 Delph The study of plant-disease interactions is of fundamental importance for improving our ability to control plant diseases and our understanding of host-pathogen coevolution. Two areas of little previous research are addressed by this project: to what extent does variation in genetic and environmnetal factors explain the patchy distribution of disease in nature, and how does disease influence the evolution of the host's breeding system? This project examines the relationship between Silene acaulis and a pollinator-transmitted fungal disease, Microbotryum violaceum to address these questions. This research will improve our understanding of host-pathogen ecology and coevolution. The results of this study may have application to the field of plant pathology, specifically disease prevention and control in crops.

小行星9411951 植物-病害相互作用的研究对于提高我们控制植物病害的能力和理解寄主-病原体协同进化具有根本的重要性。 该项目涉及两个以前很少研究的领域：遗传和免疫因素的变化在多大程度上解释了自然界中疾病的斑块分布，以及疾病如何影响宿主繁殖系统的进化？ 本研究旨在探讨无茎蝇子草与一种传粉者传播的真菌病害--紫色微孢菌之间的关系，以解决这些问题。 这项研究将提高我们对宿主-病原体生态学和协同进化的理解。 本研究的结果可能应用于植物病理学领域，特别是作物病害的预防和控制。
