- 1Bacteria on coral reef fish gills carry chemosynthesis genes, DNA study finds●DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Scientists have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. The discovery, reported by Phys.org, suggests gill-dwelling microbes may play a previously overlooked role in reef nutrient cycles and could reshape how researchers understand symbiosis on coral reefs.
