Coral reef fish gill bacteria carry chemosynthesis genes, DNA study shows
Original: DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Scientists analysing DNA from bacteria living on the gills of coral reef fish have found genes used in chemosynthesis, a process normally associated with deep-sea vent microbes rather than sunlit reefs. The findings suggest gill-dwelling bacteria may draw energy from chemicals such as sulfur compounds instead of light, hinting at a little-understood symbiotic role in reef ecosystems.
Why now: The discovery of chemosynthesis genes in reef-associated bacteria is unexpected and expands what is known about how coral reef fish and their microbes exchange energy.
