| The present study identifies quantitative trait loci (QTLs) in response to an experimental infection with the parasite responsible for bonamiosis, Bonamia ostreae, in two segregating families of the European flat oyster, Ostrea edulis. We first constructed a genetic-linkage map for each studied family and improved the existing genetic-linkage map for the European flat oyster with a set of SNP markers. This latter map now combines the best accuracy and the best estimate of the genome coverage available for an oyster species. Secondly, by comparing the QTLs detected in this study with those previously published for O. edulis in similar experimental conditions, we identified several potential QTLs that were identical between the different families, and also... |

| During the last five years, a great effort has been made to develop genomic tools in oyster species all over the world. In Europe, the Pacific cupped oyster, Crassostrea gigas, and the European flat oyster, Ostrea edulis received a special attention as they are the key species for local aquaculture. In particular, the Pacific oyster is a marine bivalve of major economical and ecological importance worldwide. Better knowledge of its physiology and its genetics contributes to optimize its aquaculture production using selective breeding or to understand its invasive behavior in some coastal areas. Current international developments of genomic resources include EST databases, BAC libraries, genome mapping and sequencing. The Genoscope (Evry, France) and the... |
