Microarray analysis highlights immune response of pacific oysters as a determinant of resistance to summer mortality.
International audience Summer mortality of Crassostrea gigas is the result of a complex interaction between oysters, their environment, and pathogens. A high heritability was estimated for resistance to summer mortality, which provided an opportunity to develop lines of oysters that were resistant (...
