· Survival strategies of corn smut fungus Ustilago maydis during host colonization
Ustilago maydis is a biotrophic fungus that infects Zea mays. During host colonization the fungus is exposed to a number of plant defense responses like for instance elevated levels of reactive oxygen species (ROS) in the vicinity of the invasion site. Depending upon the compatibility of the pathogen and the host strain this ROS stimuli can either initiate a cell death response in the pathogen or could be overcome by the defense responses of the pathogen itself. In this project we are engaged in dissecting these survival and death pathways of Ustilago maydis during a compatible and incompatible interaction with the host plant Zea mays.
· Functional characterization of U. maydis effector proteins
Effector proteins are key factors defining the virulence of a phytopathogenic fungus like Ustilago maydis. In this project we are engaged in investigating the functions of different groups of secreted effector proteins from Ustilago maydis in the context of their role in manipulating host defense responses.
· Functional proteomics of rice apoplastic fluid
This project is aimed to study the apoplastic fluid proteome of rice under conditions of pathogen invasion. Through this study we are investigating on one hand the in-planta secretome of different pathogens infecting rice and on the other hand rice secreted proteins that play crucial roles in defense against pathogen invasion.
