Fosmid library construction and end sequences analysis of the Pacific oyster, Crassostrea gigas
The Pacific oyster (Crassostrea gigas) is globally distributed and is one of the most commercially and ecologically important marine organisms. However, little is known about the genome of this species. In this study, a C. gigas fosmid library was constructed that contains 459,936 clones with an ave...
