Their use in site-specific recombination system for Bacillus Chu Lin Jen-cis strain development Bacillus Chu Lin Jen and cis (Bacillusthuringiensis) transposon Tn5401

摘要

A transposable element, or transposon, isolated from Bacillus thuringiensis (B.t.) and designated as transposon Tn5401. The invention also includes a method of using this transposon in a site-specific recombination system for construction of recombinant B.t. strains that contain insecticidal B.t. toxin protein genes and that are free of DNA not native to B.t.
