Project B4: Cell-cell communication of bacteria of the Roseobacter clade with other bacteria and algae

Cell-cell communication transforms clonal populations of bacteria into highly complex, well adapted communities. Here we unravel the quorum sensing (QS) regulon of the model organism Dinoroseobacter shibae and study interactions between Roseobacter bacteria and their eukaryotic host organisms.
