Hypothesis
Does a Vibrio zinc-metalloprotease contribute to coral disease by causing photoinactivation of coral endosymbionts?
Conclusion
The study found that a Vibrio zinc-metalloprotease is a common virulence factor in coral pathogens, leading to significant damage to coral endosymbionts and tissue lesions.
Supporting Evidence
- Coral diseases are a serious threat to coral reefs worldwide.
- Six out of nine characterized coral infectious diseases are caused by Vibrio species.
- The study identified a common virulence factor in multiple Vibrio pathogens affecting corals.
Takeaway
A harmful bacteria can make corals sick by damaging the tiny plants that live inside them, which help the corals stay healthy.
Methodology
The study used bioassays to test the effects of Vibrio supernatants on Symbiodinium cells and coral juveniles, measuring PS II inactivation.
Limitations
The study did not determine the exact process by which the metalloprotease affects Symbiodinium photosynthesis.
