Abstract:

We investigated the molecular basis for ionizing radiation IR resistance in extremophiles using the halophilic archaeon Halobacterium salinarum as a model system and several thermophilic bacteria and archaea also highly resistant to IR. Oxidative damages are the main lesions from IR and result from the production of reactive oxygen species ROS via radiolysis of water.
