    Summary

    A novel hybrid plasmid, pBE10, was created by combining RSF2124 and Staphylococcus aureus pUB110 DNA. This construct, along with its derivatives, showed molecular instability in Bacillus subtilis.

    Area of Science:

    • Molecular Biology
    • Microbiology
    • Plasmid Engineering

    Background:

    • RSF2124 (ColE1 :: Tn3) and pUB110 plasmids are key genetic elements.
    • pUB110 is known for stable maintenance in Bacillus subtilis.
    • Transposon Tn3 facilitates genetic manipulation and transfer.

    Purpose of the Study:

    • To construct a hybrid plasmid (pBE10) by combining RSF2124 and pUB110.
    • To characterize the transposition of an enlarged transposon (Tn2551) derived from pBE10.
    • To assess the stability of resulting plasmids in Bacillus subtilis.

    Main Methods:

    • Hybrid plasmid construction using DNA ligation and transformation.
    • Transposition of Tn2551 to phage lambda, pMB9, and RSF1010 plasmids.
    • Restriction and heteroduplex analysis for molecular characterization.

    Main Results:

    • Successful construction of hybrid plasmid pBE10.
    • Transposition of Tn2551 to pMB9 (pBE21) and RSF1010 (pBE32).
    • Plasmids pBE10, pBE21, and pBE32 exhibited molecular instability in Bacillus subtilis.

    Conclusions:

    • The engineered plasmids demonstrate potential for genetic studies in Bacillus subtilis.
    • Molecular instability requires further investigation for practical applications.
    • Hybrid plasmid technology offers avenues for exploring gene transfer mechanisms.
