Outline of Final Research Achievements

The Pacific oyster Crassostrea gigas accumulates reserves of glycogen in winter for gametogenesis and spawning in summer. After spawning during high-temperature summers, oysters become highly nutrient depleted; therefore, rapid glycogen synthesis and storage is important for recovery from these stresses. Despite the importance of glycogen storage, there is little detailed information on the underlying molecular mechanisms. Given this deficiency, we analyzed the gene expression profiles of oyster glycogen storage organs using next-generation sequencing. Pathway analysis revealed that glycogen storage has a relationship to insulin signaling pathway. This oyster insulin gene was a newly determined sequence.
