Outline of Final Research Achievements

For the purpose of increasing transformation efficiency of Bacillus subtilis for long DNA, we tried to develop a new transformation system that uses chemically modified DNA. We constructed and tested B. subtilis strains that are inserted protein unit that recognizes chemically modified DNA into genes responsible for natural transformation. The resulted strains, however, showed same transformation efficiency for chemically modified DNA with that for natural DNA. Thus we couldn’t get evidence that indicates our developed strains are able to specifically incorporate chemically modified DNA within this study period.
