Pathodopsis: Patho(gens on Arabi)dopsis
Plant disease is a major threat for agricultural crops, yet rarely observed on wild plants. Nevertheless, wild plants, just like crop plants, are host to a large number of microbes, including species and strains known as pathogens. To understand how Arabidopsis thaliana copes with microbial pressure, we collect wild plants from numerous habitats. We focus on two prominent pathogens of the species, the specialized oomycete Hyaloperonospora arabidopsidis (HpA), as well as bacteria of the genus Pseudomonas, and employ genome sequences to describe their diversity. Ultimate goal is to identify signatures of co-evolution within both host and microbial genomes.

Collection
We genotype wild plants as well as the microbes that live on them. When possible, we isolate individual microbial strains.
