Abstract: Deinococcus radiodurans is concerned with by the researchers for its high resistance to ionizing radiation, UV, and other mutagenic agents. These phenotypic characters of D. radiodurans are mainly attributed to its ability to protect proteins from being damaged by reactive oxygen species in adverse circumstances. Environmental restoration, breeding drought-resistant crops and virus-resistant animals, and tumor control will all benefit from the researches of D. radiodurans. Restoring the environments polluted by radioactive wastes is the most possible field where this bacterium can be applied. Engineering D. radiodurans for restoring radiomaterial-polluted environment is much cheaper than common physicochemical methods. The high drought-resistance of D. radiodurans suggests the existence of drought-resistant genes in D. radiodurans genome, and looking for these genes has potential prospect for breeding drought-resistant crops.
