Project Description

This project has aimed to develop the technology for studying global gene expression in microorganisms sampled directly from the environment, our study area was Antarctic Peninsula coastal waters, where temperatures are constantly cold (-2 to -1o C) . We are working on characterizing the diversity of the coastal Antarctic marine bacterioplankton, and have sequenced a number of environmental genomic DNA fragments cloned directly from the environment.
