Current Research Project
My PhD project is part of a large interdisciplinary research consortium in the DFG funded priority program Rhizosphere Spatiotemporal Organisation - a Key to Rhizosphere Functions (SPP2089). In this consortium, 25 research projects from more than 18 institutions from various disciplines, such as soil physics, soil chemistry, plant physiology, microbiology, and modelling collaborate in order to identify spatiotemporal patterns and link soil, plant and microbial functions in the rhizosphere of Zea mays (maize). The experimental research platform combines climate chamber experiments under highly controlled conditions with field sampling, in order to understand and dissect early and late emerging properties.
My research project (ROOTGENES) focuses on the gene expression patterns in the roots of maize that emerge as a result of a variety of parameters, such as soil type, plant genotype, and microbial interplay.
The main research questions are stated as follows:
- How does the spatial organization of the root affect plant gene expression in relation to the microbiome, and how do soil properties and root hair formation influence this?
- Is the spatiotemporal rhizosphere re-organization or inoculation with plant growth promoting bacteria (PGPB) reflected by changes in the gene expression of microbiome perception, defense signalling, exudation and nutrient acquisition?
