Directed, efficient, and versatile modifications of the Drosophila genome by genomic engineering
Open accessAbstract
With the completion of genome sequences of major model organisms, increasingly sophisticated genetic tools are necessary for investigating the complex and coordinated functions of genes. Here we describe a genetic manipulation system termed “genomic engineering” in Drosophila . Genomic engineering is a 2-step process that combines the ends-out (replacement) gene targeting with phage integrase φC31-mediated DNA integration. First, through an improved and modified gene targeting method, a founder knock-out line is generated by deleting the target gene and replacing it with an integration site of φC31. Second, DNA integration by φC31 is used to reintroduce modified target-gene DNA into the native locus in the founder knock-out line. Genomic engineering permits directed and highly efficient modifications of a chosen genomic locus into virtually any desired mutant allele. We have successfully applied the genomic engineering scheme on 6 different genes and have generated at their loci more than 70 unique alleles.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
