Development of a Medium Density Combined-Species SNP Array for Pacific and European Oysters (Crassostrea gigas and Ostrea edulis).

Development of SNP-genotyping arrays in two shellfish species.

Use of SNPs has been favoured due to their abundance in plant and animal genomes, accompanied by the falling cost and rising throughput capacity for detection and genotyping. Here, we present in vitro (obtained from targeted sequencing) and in silico discovery of SNPs, and the design of medium-throughput genotyping arrays for two oyster species, the Pacific oyster, Crassostrea gigas, and Europe...

Comparison of haemocytic parameters among flat oyster Ostrea edulis stocks with different susceptibility to bonamiosis and the Pacific oyster Crassostrea gigas.

Farming of the flat oyster Ostrea edulis in Europe is severely constrained by the protozoan Bonamia ostreae. The introduction of the resistant species Crassostrea gigas has been a relief for the farmers, while the pilot programmes to select O. edulis strains resistant to bonamiosis performed in various countries can be seen as a promising strategy to minimise the effects of bonamiosis. However,...

Biochemical and elemental composition of the offshore-cultivated oysters Ostrea edulis and Crassostrea gigas

Development of a medium density combined-species

48 SNP arrays are enabling tools for high-resolution studies of the genetic basis of 49 complex traits in farmed and wild animals. Oysters are of critical importance in many 50 regions from both an ecological and economic perspective, and oyster aquaculture 51 forms a key component of global food security. The aim of our study was to design a 52 combined-species medium density SNP array for Pac...

The molecular phylogeny of oysters based on a satellite DNA related to transposons.

We have analysed a centromeric satellite DNA family that is conserved in several commercial and non-commercial oyster species (Ostrea edulis, O. stentina, Crassostrea angulata, C. gigas, C. gasar, C. ariakensis, C. virginica and C. sikamea). This satellite DNA family is composed of AT-rich repeat sequences of 166+/-2 bp and presents a 9-bp motif similar to the mammalian CENP-B box. The homology...
