Outline of Final Research Achievements

Toward cloning of whole genome of a bacterium, Spiroplasma, whole genome of this bacterium was extracted and cut by the rare-cutter restriction enzymes. Then patterns of genome fragments were analyzed by pulse-field gel electrophoresis. These genomic fragments were used for the TAR (Transformation-Associated Recombination)-cloning in yeast cells. Lots of positive clones were obtained, and these clones were checked by several methods. Whole sequences of the insert of several positive clones were analyzed by the Illumina sequencing method. As a result, there was almost no mutation in these inserts, thus this method would be useful for cloning of bacterial genomes.

Academic Significance and Societal Importance of the Research Achievements

難培養細菌(難培養性細菌・未培養細菌)と呼ばれる細菌は、培養が不可能もしくは非常に困難な細菌である。難培養細菌は決して珍しいものではなく、環境中の微生物の99%以上は培養できないことが明らかとなっている。細菌のゲノムを自在に改変する技術はいくつか報告されているが、難培養細菌に応用できるものは限られている。本研究では細菌ゲノムを丸ごとクローニングして配列を改変することで、難培養細菌の遺伝子を改変することを目指し、そのための全ゲノムクローニングを行った。得られた結果は、今後の細菌ゲノム研究の発展に寄与すると考えられる。
