Decoded the genome of the oyster
A team of scientists from China, the U.S. and Europe has carried out the work of sequencing the Genome of the oyster . An analysis of the entire genetic map of the mollusc, the first of its kind in genome to be deciphered.
This is the Pacific oyster, Crassostrea humps, with which it is expected to reveal many of the secrets of his great adaptation to the environment and the complexity in the formation of the shell.
The research, published in Nature, shows how oysters survive the harsh environment of the estuary and the sea. According to scientists, shows how they adapt in high stress environments.
Molluscum has dozens of genes that protect it from extreme temperatures and salinity itself, where the land meets the sea. A map of the genome of the oyster that gives us an idea of how it adapts to marine life and how it is able to form its complex shell.
It also reveals secrets that may help scientists to breed fast-growing oysters with a higher survival rate. According to Peter Holland, Oxford professor and coauthor of the study:
The oyster has more than 80 genes that protect from stress. The study provides a fascinating insight into the life of a creature adapted to a complex area. In fact, we can see a reflection in the genome of these adaptations, an adaptation of millions of years for these animals to deal with an incredibly tough environment.
Fang Xiaodong, the other principal investigator along with Holland, gives the keys of the event and its possible future applications:
The genome assembly approach the oyster opens new avenues for researchers to better decipher the genomes with high heterozygosity and high polymorphism. The study gives an idea of the overall understanding of the genomes of molluscs with a level focused on diversity, evolutionary adaptation mechanisms, developmental biology and genomics assisted reproduction.
And is that the research will provide a set of keys and important resources for the study of biology and breeding molluscum own alongside other marine species.Tags: Genome, Ostra
