Research focus

Plant secondary metabolites play critical roles in the interaction of plants with their environment. To better understand the fundamental biology of plant-microbiome interactions, we aim at identifying novel “metabolic regulons”, including transcription factors, biosynthetic enzymes and transporter proteins, which are important in the production of secondary metabolites shaping endophytic community of plants in the rizosphere. Once identified, the regulon will be introduced into a “synthetic plant”, which will correspondingly lack or overproduce specific bioactive metabolites in roots and will therefore manifest beneficial interactions with the plant microbial community.
