Abstract:

Deinococcus radiodurans is one of the most radiation-resistant organisms on Earth as it has strong resistance to the DNA and protein damage induced by ionizing radiation, ultraviolet rays, H2O2 and other damage factors. It has known that the efficient DNA repair capacity is the key to this superior radiation resistance though the detailed mechanism is still poorly understood. In this paper the mechanism dealing with radiation damage and repair in resent research will be reviewed.

Key words: Deinococcus radiodurans, Radiation damage, Repair mechanism
