The endogenous plasmid pUE30 from radioresistant bacterium D. radiopugnans strain ATCC19172 or a derivative thereof is used as a vector that can autonomously replicate in bacteria of the genus Deinococcus. It may be used to construct a shuttle vector that also contains a plasmid capable of autonomous replication in E. coli or a derivative thereof and which can replicate in both a bacterium of the genus Deinococcus and E. coli. 展开▼
