Functional Genomics in marine diatoms

We are developing a insertional mutagenesis library in the marine diatom Skeletonema marinoi based on electroporation of cell cultures with linear DNA fragments containing selection markers. The mutagenesis library will be used to answer questions regarding diatoms adaptations to stresses associated with antropogenic climate change. 

Microbiome of Skeletonema Marinoi

In parallel we are investigating the microbes assoiciated with S. marinoi, which has led us to initiate the full genome sequencing of 9 bacterial strains associated with the diatom. Investigations are now underway to assay the identified strains on a functional level and their interaction with the host diatom.
