Abstract

Bacillus subtilis was engineered to produce circular subgenomes that are directly transmittable to another B. subtilis. The conjugational plasmid pLS20 integrated into the B. subtilis genome supported not only subgenome replication but also transmission to another B. subtilis species. The subgenome system developed in this study completes a streamlined platform from the synthesis to the transmission of giant DNA by B. subtilis.

Keywords: B. Subtilis; conjugational plasmid; genome synthesis; pLS20; subgenomes.
