Latest Coccolithovirus Stories
Sediments buried beneath the Black Sea contain ancient virus and host DNA A scientist analyzing ancient plankton DNA signatures in sediments of the Black Sea has found that the same genetic populations of a virus and its algal host can persist--and coexist--for centuries. The findings have implications for the ecological significance of viruses in shaping ecosystems in the ocean, and perhaps in fresh water. "The finding that the DNA of viruses and their algal hosts can be preserved in the...
Coccolithovirus, a giant double-stranded DNA virus, infects Emiliania huxleyi, a species of coccolithophore. The virus was first observed in 1999 by W.H. Wilson and his team at the Marine Biological Association. It was sequenced for the EhV-86 strain during the summer of 2005, and was found to be a "giant-virus" having 472 protein-coding genes. It is the largest known marine virus by genome.
