Researchers Uncover Genetic Payload Of Ancient Plankton In Black Sea Sediments
2013-05-07 10:23:32

April Flowers for redOrbit.com - Your Universe Online Sorting through the vast amounts of genetic data from the Black Sea sediment record, Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was astounded by the variety of past plankton species that left behind their genetic makeup. This vast amount of data is called the plankton paleome. The Black Sea is semi-isolated from other bodies of water, and highly sensitive to climate driven environmental changes....

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...
