Research Abstract

The genome studies of the Antarctic bacteria living at low temperature environments are very limited and to be developed further more. I have tried to understand on the genome-level for the mechanisms concerning with low temperature environment adaptation of an Antarctic bacterium. I isolated a psychrophilic bacterium Pseudomonas sp. MP1 from a"Moss Pillar", which Japanese Antarctic Research Expedition had discovered in East Antarctica, and sequenced the complete genome of it. The comparative genome analysis of MP1 with related Pseudomonas sp. isolated in other continents revealed that genes of MP1 has adapted lower temperature environments on entire genome-level in its evolution. This study will be the first report for the bacterial entire genome-level adaptation to lower temperature environments in Antarctica.
