Fluorescence in situ hybridisation of a gill filament from a <i>Bathymodiolus</i> mussel


Building a home – Understanding host cytoskeleton changes of bacteriocytes in Bathymodiolus mussels 

Bathymodiolus mussels thrive in the harsh conditions of the deep sea due to their bacterial partners. These chemosynthetic symbionts generate energy by sulfur-oxidation (SOX) or methane-oxidation (MOX) to fix carbon. Some Bathymodiolus mussels harbor either both types of symbionts and some others only one of them in bacteriocytes of their gill tissues. Additionally, the symbionts can be found in different locations in the bacteriocytes, sometimes inducing rearrangements of the host cytoskeleton. I aim to use microscopy and omics techniques to understand the factors involved in symbiont entry and cytoskeleton rearrangements.
