Research Group: Microbial Interactions
Our research focuses on microbiome assembly in soil, subsurface soil, rhizosphere and hyphosphere, as well as functioning of root- or hyphae-associated bacteria with the potential to promote plant or fungal growth.
Microbial communities in soil, associated with plant roots or fungal hyphae, provide essential ecosystem services, and are shaped by complex interactions between microorganisms, plants and the surrounding environment. We investigate interactions at the molecular level by combining genomics, transcriptomics and marker/reporter gene technologies with biochemical analyses to decipher the mode of action. The colonization strategies used by these beneficial microorganisms, as well as their responses to environmental stressors that might interfere with their function.
Microbial inoculants for plant growth promotion: we investigate how PGPRs colonize the plant rhizosphere, how they interact with native microbial communities, and how they change plant physiology and growth.
Isolation of novel bacteria from soil and rhizosphere: We are working on the design of “informed” cultivation approaches where predictions from metagenomes are used to increase the chances of capturing so far uncultivated bacteria belonging to abundant but so-far overlooked taxa.
Bacteria associated with fungal hyphae: We work to clarify the factors shaping bacterial communities associated with hyphae of phosphate-solubilizing fungi (biofertilizers) under realistic soil conditions.
Microbiomes in deep soil layers and in rhizosphere of deep-rooted crops: we aim to unravel the microbial life styles in hot spot i.e. deep roots and tectonic fractures in subsurface soil.
Environmental stressors significant for fate and persistence of microbial inoculants in soil. We aim to provide novel knowledge on the significance of environmental stressors as bottlenecks for performance of plant growth promoting bacteria under realistic soil conditions.
