The release or exudation of nutrients, signals or toxic compounds by the plant root into the rhizosphere and root endosphere creates selective environments for microbes. However, the molecular mechanisms by which interactions between plant host cells and root associated microbes are influenced by root exudates are still poorly understood. We investigate mechanistic principles of plant-exudate driven interaction in the rhizosphere with an interdisciplinary team of experts in microbial ecology, chemical analytics, plant symbiosis, physiology and genetics. We aim to identify plant metabolite - bacterial target gene connections (M-GCs), which promote or supress bacterial competitiveness in the rhizosphere, bacterial colonization of the root and plant performance through bacterial activity. As host plant, we will use the model legume Lotus japonicus, which is able to interact with the well studied microbial plant symbionts, rhizobia and arbuscular mycorrhizal fungi (AMF), in combination with small synthetic communities (SynCom). Furthermore, we include Acidovorax as a commensal bacterial model, because a diversity of strains discovered from L. japonicus roots had contrasting effects on the growth of L. japonicus.
