Signal Transduction and Networking in Plant – Pathogen Interactions
Understanding the molecular mechanism of plant defense systems is critical in determining how plants defend themselves against various stresses, including pathogens and applying this knowledge to improve agricultural production and protect environment against negative impact from pesticides and fungicides.
The long-term goal of our laboratory is to understand the signaling pathway to induce plant resistance against various environmental stresses including pathogen infection. We use several pathogens and chemicals to analyze the signal transduction pathway in the model dicot plants, Arabidopsis/tobacco and the monocot plant, rice. Currently we focus on the characterization of the Arabidopsis mutant cpr22. We want to elucidate how this mutation causes enhanced resistance against several pathogens and isolate novel components, which are involved in the pathogen resistance signaling pathway using molecular and genetic approaches.
