Oyster genome uncover the stress adaptation and complexity of shell formation
Date:9/19/2012

ormation, but neither of them is accurate enough. In this study, by sequencing the peptides in the shell, researchers identified 259 shell proteins, and further analysis revealed that shell formation was a far more complex process than previously thought. They found many diverse proteins may play important roles in matrix construction and modification. The typical ECM proteins such as Laminin and some collagens were highly expressed in shells, suggesting that shell matrix has similarities to the ECM of animal connective tissues and basal lamina. Hemocytes may mediate fibronectin (FN)-like fibril formation in the shell matrix as they do in ECM. Furthermore, the functional diversity of proteins showed that the cells and exosome may participate in the shell formation.

Xiaodong Fang, Primary Investigator of this project at BGI, said, "The assembly approach of Oyster genome opens a new way for researchers to better crack the genomes with high-heterozygosity and high-polymorphism. The Oyster genome sheds insights into the comprehensive understanding of mollusc genomes or even lophotrochozoa genomes at the whole genome-wide level, with focuses on the studies of diversity, evolutionary adaptive mechanisms, developmental biology as well as genomics-assisted breeding.
