Plants associate with microbial communities called the microbiota, which contribute to plant health. However, at the same time, they come under attack from harmful microbes. Problematically for plants, these microbial friends and foes are often alike. Thus, a fundamental question is how plants discriminate between harmful and beneficial microbes in order to survive and reproduce in nature. Our major goal is to understand the interaction between plants and microbes at the molecular and global levels using molecular genetics, genomics, evolutionary approaches. Our research uses the model Brassicaceae plant Arabidopsis thaliana as well as Poaceae Zea mays and bacterial and fungal pathogens as well as plant microbiota.
