The oyster genome reveals stress adaptation and complexity of shell formation
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.
Oyster Reefs at Risk and Recommendations for Conservation, Restoration, and Management
Native oyster reefs once dominated many estuaries, ecologically and economically. Centuries of resource extraction exacerbated by coastal degradation have pushed oyster reefs to the brink of…

An integrated, highly complex innate immune system that exhibits remarkable discriminatory properties and responses to different pathogens as well as environmental stress has arisen through the adaptive recruitment of tandem duplicated genes.
Transcriptome analysis reveals strong and complex antiviral response in a mollusc.
Scallop genome provides insights into evolution of bilaterian karyotype and development
A high-quality, chromosome-anchored reference genome for the scallop Patinopecten yessoensis, a bivalve mollusc that has a slow-evolving genome with many ancestral features, finds unexpected diversity in phototransduction cascades and a potentially ancient Pax2/5/8-dependent pathway for noncephalic eyes.
Molluscan aquaculture in China
The rapid development of intensive mariculture during the past decade may have exceeded the carrying capacity of some areas and contributed to deterioration of the culture environment.
Discovery of genes expressed in response to Perkinsus marinus challenge in Eastern (Crassostrea virginica) and Pacific (C. gigas) oysters.
AFLP-Based Genetic Linkage Maps of the Pacific Oyster Crassostrea gigas Thunberg
Most distorted markers were deficient for homozygotes and closely linked to each other on the genetic map, suggesting the presence of major recessive deleterious genes in the Pacific oyster.

Analysis of sex ratios in 86 pair‐mated families of the Pacific oyster, Crassostrea gigas Thunberg, revealed significant paternal effects, which corresponded to two types of sires, so that MF are true males and FF are protandric females that are capable of sex change.
Chromosomal Rearrangement in Pectinidae Revealed by rRNA Loci and Implications for Bivalve Evolution
The ability to tolerate significant chromosomal loss suggests that the modal karyotype of Pectinidae and possibly other bivalves with a haploid number of 19 is likely tetraploid; i.e., at least one genome duplication has occurred during the evolution of Bivalvia.
