title: Seasonal changes of nucleotides in mussel (Mytilus galloprovincialis) mantle tissue.
abstract: Seasonal variations of nucleotides in Mytilus galloprovincialis mantle tissue were analyzed. Separation and quantification was achieved by reversed-phase high-performance liquid chromatography. Total nucleotides show a pronounced seasonal variation with maximum and minimum values in autumn and spring, respectively. Adenine nucleotides accounted for the major part in spring and summer, guanosine and cytidine nucleotides in winter; uridine nucleotides were relatively constant throughout the year. Their inverse variation suggests inter-conversion among them and the maintenance of the potential cell energy in winter by other triphosphate nucleotides different from ATP. These results reflect environmental and nutritional conditions, and also the reserves and gametogenic cycles taking place in M. galloprovincialis mantle tissue.
