Molecular Ecology of the Rhizosphere

research group Prof. Dr. Joost T. van Dongen

in coorperation with Jens Schwachtje (MPI-MP)

Plant roots are generally colonised by many different microorganisms. Some of these are known to have beneficial effects on plant growth and performance. We isolated various rhizosphere bacteria from wild-grown Arabidopsis and selected for bacterial species that promote plant growth under various different growth conditions. In order to understand the regulation of primary metabolism upon bacterial colonization of plant roots, it is being screened for metabolic and transcriptional changes in the plant that are induced by the beneficial rhizobacteria.
