Outline of Final Research Achievements

In this project, I aimed to develop a new technology to construct heterologous genome fusant bacterial strain. First, protoplast fusion experiments that cause cell fusion were performed using various bacterial pairs. However, none of them produced a heterologous genome fusant. Next, to replicate and maintain heterologous genome in E. coli, the sequence of a single copy plasmid derived from E. coli was introduced to the Corynebacterium glutamicum genome. Then, the recombinant C. glutamicum strain was fused with E. coli by protoplast fusion. It was confirmed that the obtained fusant strains carry both E. coli and C. glutamicum genome sequences.

Academic Significance and Societal Importance of the Research Achievements

有用微生物の育種には、宿主には無い性質を付与するために、外来遺伝子情報を大規模に導入することが重要である。しかし、ゲノムスケールで宿主に異種ゲノムを組換える技術は、現時点では枯草菌や酵母といった特殊な宿主に限定されていた。本研究により、一回の細胞融合実験により大腸菌に異種細菌ゲノムを導入することが可能であることが明らかになった。こうした技術を用いることで、有用微生物の新しい育種法の開発へと応用が期待できる。
