Oysters are important for both marine ecosystems and aquaculture, but they are under threat from climate change, pollution, and disease.Recent studies of oyster genomes-such as the Pacific oyster (Crassostrea gigas) and the Hong Kong oyster (Magallana hongkongensis)-have uncovered key differences in their genetic structure, gene activity, and stress responses. These discoveries help explain how oysters manage to survive in environments with different salinity, temperature, and pathogens. The comparison between C. gigas and M. hongkongensis shows clear genetic divergence related to their habitats. By identifying genes linked to stress tolerance, researchers can support future breeding and conservation efforts-especially as climate conditions continue to change.
