Abstract: Deinococcus radiodurans is one of the most radiation-resistant organisms that was found on the earth,and has very high resistance to UV,drought,and mutagenic agents. D. radiodurans has drawn attentions from scientists around the world,and there are many reports about its radiation-resistant mechanisms. In this paper the recent progresses on radiation-resistant mechanisms of D. radiodurans are summarized from DNA-repair pathway,antioxidative defense system,special survival approaches,and cellular purification system. The development trends and future prospects of radiation-resistant mechanisms of D. radiodurans are also discussed,the aim of this paper is to provide some foundations for further study of radiation-resistant mechanisms of the bacteria.

Key words: Deinococcus radiodurans, radiation-resistant mechanisms, DNA-repair, antioxidant
