Popis: Vectors derived from the Drosophila P element transposon are widely used to make transgenic Drosophila. Insertion of most P-element-derived vectors is nonrandom, but they exhibit a broad specificity of target sites. During experiments to identify cis-acting regulatory elements of the Drosophila segmentation gene engrailed, we identified a fragment of engrailed DNA that, when included within a P-element vector, strikingly alters the specificity of target sites. P-element vectors that contain this fragment of engrailed regulatory DNA insert at a high frequency near genes expressed in stripes.
