Mitochondrial DNA Analysis of the Mediterranean Mussel, Mytilus galloprovincialis

Abstract (Summary)

The purpose of this study was to analyze the genetic diversity of the Mediterranean mussels, Mytilus galloprovincilias, along the coasts of the Strait of Istanbul, which connects the Sea of Marmara to the Black Sea. We believe that during the Pleistocene era, which had several glacial periods when ocean water levels were lower than present day, the Sea of Marmara was isolated from the Mediterranean and Black Seas. Our hypothesis is that there is a potentially undescribed and unstudied mussel population with a unique evolutionary history. Based on our preliminary data of the mitochondrial DNA, we have found evidence of a unique population. In order to examine phylogenies based on DNA sequence information, our preliminary studies compared our DNA sequences with sequences published in GenBank. Based on this comparison, we found that there were two unique haplotypes in the Strait of Istanbul which were distinct from other haplotypes in the Mediterranean. Possible explanations are an introduction of Atlantic haplotypes via ballast water or Pleistocene isolation of the Sea of Marmara. This research is significant, because very little research has been published on populations of Mytilus galloprovincialis in the Strait of Istanbul, and in addition, if our hypothesis proves to be true, this research will provide insight into the influence of Pleistocene vicariance on population genetics of marine species.
