MPR 3/2012The Sea as a Gene Pool
The oceans are full of bacteria. Outwardly, they all look much the same, but there are many different species living a variety of ways of life. This has led Hanno Teeling, Bernhard Fuchs and Frank Oliver Glöckner from the Max Planck Institute for Marine Microbiology in Bremen to analyze bacterial diversity in the oceans with the aid of metagenomics. To do this, they first throw the whole bacterial genome into one pot, then decode the DNA molecules and sort the genetic mix back into individual bacterial groups.

The depths of the ocean are a hostile environment. In a bid to defy these adverse conditions, many organisms have teamed up to form close relationships called symbioses. Nicole Dubilier and her colleagues at the Max Planck Institute for Marine Microbiology in Bremen keep discovering new symbioses that provide these deep-sea inhabitants with a guaranteed energy supply.
