| Research Abstract |
Horizontal gene transfer (HGT) is known to be an important mechanism for acquiring new genetic information in bacterial evolution. Mobile genetic materials, such as plasmid and transposon, contribute to HGT events among bacteria, while their transfer frequency and geological distribution have yet to be characterized well. This study demonstrated the worldwide distribution of TnMERI1 type transposons among bacteria. Further quantitative analysis showed the uneven distribution of TnMERI1 type transposons in soil environments. These results indicate the occurrence of bacterial HGT in natural environment.
