题目2：Chemical- and R protein-mediated defense in plants

Research
The overall goal of our research is to help understand how specific signaling pathways are induced during host-pathogen interaction, how these pathways communicate with each other and the molecular mechanisms underlying such regulations. We are using Arabidopsis (www.arabidosis.org) as a model plant system and are studying its interaction with a viral pathogen turnip crinkle virus (TCV) and an oomycete pathogen Peronospora parasitica. With regards to signaling mechanisms our main interest is to decipher the role of fatty acid signaling pathways in plant defense.
