We are interested in the functional genomics of two symbiotic interactions of legume plants with soil microbes: The formation of root nodules in symbiosis with rhizobial prokaryotes and the arbuscular mycorrhiza interaction with soil fungi of the genus Glomus. Whereas nodulation leads to symbiotic nitrogen fixation, arbuscular mycorrhiza improves the uptake of phosphorus and minerals from the soil. We have chosen the model legume Medicago truncatula for our research, since excellent functional genomics tools are available. In addition to our focus on model legumes, the crop legumes Pisum sativum (pea) and Vicia faba (broad bean) are used. Our experimental techniques comprise high-throughput EST-sequencing, microarray and GeneChip hybridizations, applied bioinformatics, expression of promoter-reporter gene fusions in transgenic roots, as well as the functional analysis of candidate genes in plant mutants.
