Molecular Plant Microbe Interactions
Plants are colonized by a vast variety of microbes, some of which are beneficial, others are pathogenic. Associations with beneficial microbes can make plants more resistant to stress, and result in higher yield. To exploit these beneficial interactions on an agricultural scale, the mechanisms of plant-microbe interactions need to be elucidated. We focus on the following questions:
How do plants perceive pathogenic and beneficial microbes, and how do they alter their metabolism in response? Do plants adjust the quality and quantity of metabolites exuded by roots to interact with specific microbes? Which transport proteins are involved in this process? In summary, how do plants shape the microbial communities in their vicinity?
We use state-of-the art tools from biochemistry, molecular biology, analytical chemistry and more to elucidate molecular mechanisms of plant-microbe interactions.
