MicGeo - Microbiomes of Plants and Soils in Action.
The group investigates microbiomes (i) in context of climate protection and adaptation in soils and agroecosystems and (ii) for the resilience of crops to abiotic, climate-related stressors. A further aim is to scale up microbiome-mediated ecosystem functions (mESF) at the ecosystem level, taking into account spatial heterogeneity of soil properties and vegetation. In addition, the working group is dedicated to application-oriented research to enable effective microbiome management on arable land and grassland. Gene markers, metagenomics, stable isotope sampling and RNA-based methods, including bioinformatics, to determine the functions and dynamics of microbiomes are core competencies of the working group. In addition, soil enzyme and gas analytics are used to characterise microbiomes metabolism. And new key microbes are isolated and characterised. Experimental studies are conducted on individual plants (pot experiments) and at the ecosystem level (field & landscape).
