TL;DR: The sequencing and assembly of the oyster genome using short reads and a fosmid-pooling strategy and transcriptomes of development and stress response and the proteome of the shell are reported, showing that shell formation in molluscs is more complex than currently understood and involves extensive participation of cells and their exosomes.

TL;DR: The highly polymorphic genome of the pearl oyster is sequenced and a large set of novel proteins participating in matrix-framework formation are identified, including components similar to that found in vertebrate bones such as collagen-related VWA-containing proteins, chondroitin sulfotransferases, and regulatory elements.

TL;DR: Differences in size and shape of the rDNA-bearing chromosome represent a major divide between Asian-Pacific and Atlantic species of Crassostrea and suggest that chromosomal divergence can occur under seemingly conserved karyotypes and may play a role in reproductive isolation and speciation.

TL;DR: High levels of genetic diversity and gene expansion in oysters are likely adaptations to variable environments, and studies on molecular adaptations to recent and historic climate change may provide insights into the evolution and speciation of oysters.
