Division of Plant Pathology and Microbiology in Plant Sciences Department
Research project:
Develop imaging technology for the study of biofilms on plants

This project is utilizing previously characterized microbial derivatives of the root-colonizing biological control bacterium Pseudomonas aureofaciens strain 30-84 that serve as bacterial biosensors of intercellular communication to study the role of signaling in microbial interactions in bacterial biofilms. This project has produced fluorescently labeled derivatives of these strains that we can visualize on plant roots. It is hoped that understanding the organization and dynamics of biofilms on plants will provide insight into the ecology of natural bacterial communities and ways manipulate these communities to improve agriculture and the environment.
