Research Abstract |
To clarify features and frequencies of bacterial recombinational events, two closely related bacterial strains were mixed and incubated in a sterile soil sample. After a long period of incubation cells were recovered on a solid medium, and subjected to illumina sequencing. The illumina sequencing reads were analyzed by developing and using a computational tool named 'ShortReadManager', which is now released at http://www.ige.tohoku.ac.jp/joho/gf/index.php, and I found no evidence that indicates recombination between the two strains. On the other hand, mutated DNA fragment of 16S ribosomal RNA gene was inserted into a genome of a soil bacteria, in which 5 copies of rRNA gene are present. The mutated fragment was expected to be replaced by the wild-type copy. By quantitative PCR analysis, we found a evidence that suggests concerted evolution of multi gene family.
