Mitochondria transitioned from free-living bacteria to obligate symbionts of eukaryotic cells. In this process they gave up a good part of their genome (either lost or transferred to the nucleus of their host cell) and their reproductive independence (which is now controlled by the nucleus).
Little is known regarding this fundamental transition. We are interested in which scenarios favor the transfer of genes from bacteria engulfed by a cell to the nucleus, and the transfer of reproductive control to the host nucleus.
In the first place we will do this through studying models of the evolutionary dynamics of mitochondrial genes. By taking a gene eye-view we will be able to determine when the gene copies in the nuclear genome would outcompete the ones in the mitochondrial genome. We plan to test model predictions using model organism such as Chlamydomonas and Yeast.
