-i(BACILLUS THURINGIENSIS) TRANSPOSON Tn5401 AND ITS USE IN A SITE-SPECIFIC RECOMBINATION SYSTEM FOR -i(BACILLUS THURINGIENSIS) STRAIN DEVELOPMENT

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.
