The Pacific oyster Crassostrea gigas (Thunberg, 1793) is a marine bivalve belonging to Phylum Mollusca, one of the most species-rich but genomically poorly explored phyla. It is one of the most important aquaculture species worldwide, a keystone species of coastal and estuarine ecology, and a popular model species for marine biological research. To advance basic and applied research using the Pacific oyster as a model species, the Institute of Oceanology of Chinese Academy of Sciences, Beijing Genomics Institute and Rutgers University, in collaboration with a team of international scientists initiated the Oyster Genome Project (OGP) in 2008. De novo sequencing of the highly polymorphic and complex genome of the Pacific oyster with short next generation sequencing is a major challenge. After 4 years of research and development, OGP assembled the Pacific oyster genome using short sequencing reads, and a novel fosmid-pooling and hierarchical assembly strategy. This online database is developed as a shared resource to enable and stimulate research by the worldwide scientific community.
