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.
