Removal of competing bacteria in coral microbiome through“trojan virus”:A newly discovered mechanism of coral pathogenicity

Coral reefs are underwater ecosystems characterized by reefbuilding corals.These reefs are complex three-dimensional structures formed by colonies of coral polyps held together by calcium carbonate,and play an important role in the global carbon cycle(Kinsey and Hopley,1991).Although coral reefs cover only approximately 0.5% of the global sea floor,they serve various ecological functions,such as ecological resource restoration,environmental regulation。
