Research interests:

By comparing the genomic features of closely related organisms, we can reconstruct the genomic changes that have occurred when species diverged. For example, by identifying the presence and absence of genes in the genomes of existing species we can deduct the evolutionary changes that happened at the ancestral nodes of a phylogenetic tree. In this manner, molecular correlates with evolutionary transitions can be investigated to reveal the genetic toolkits associated with certain organismic lifestyles and functional niches. Our research project employs comparative genomic methods to analyse the evolution of protein interaction networks, and how they are integrated across symbiotic partners, in a functional context. 

We concentrate on pioneering communities, i.e. meta-organisms that are the first to conquer new, and often extreme, habitats, such as saline and nutrient-poor soils. In the framework of this project we plan to sequence multiple species of the plant genus Lysimachia (family Primulaceae). A member of this genus, sea milkwort (Lysimachia maritima or Glaux maritima), is part of primary succession communities in European coastal areas, while other Lysimachia species occur mainly in non-saline inland habitats. By examining the functional content of Lysimachia genomes and their root symbionts we aim to shed light on how sea milkwort is able to grow in a pioneering community in a high saline environment and in how far this is accomplished with the help of a symbiotic metabolic toolkit. This project is financed by the LOEWE Centre for Translational Biodiversity Genomics (https://tbg.senckenberg.de/).
