Highly Improved Gene Targeting by Germline-Specific Cas9 Expression in Drosophila

Open access
Kondo, Shu, Ueda, Ryu·2013·Genetics

Abstract

We report a simple yet extremely efficient platform for systematic gene targeting by the RNA-guided endonuclease Cas9 in Drosophila. The system comprises two transgenic strains: one expressing Cas9 protein from the germline-specific nanos promoter and the other ubiquitously expressing a custom guide RNA (gRNA) that targets a unique site in the genome. The two strains are crossed to form an active Cas9–gRNA complex specifically in germ cells, which cleaves and mutates the target site. We demonstrate rapid generation of mutants in seven neuropeptide and two microRNA genes in which no mutants have been described. Founder animals stably expressing Cas9–gRNA transmitted germline mutations to an average of 60% of their progeny, a dramatic improvement in efficiency over the previous methods based on transient Cas9 expression. Simultaneous cleavage of two sites by co-expression of two gRNAs efficiently induced internal deletion with frequencies of 4.3–23%. Our method is readily scalable to high-throughput gene targeting, thereby accelerating comprehensive functional annotation of the Drosophila genome.

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.
