The CRISPR/Cas system can be used as nuclease for in planta gene targeting and as paired nickases for directed mutagenesis in Arabidopsis resulting in heritable progeny

Schiml, Simon, Fauser, Friedrich, Puchta, Holger·2014·The Plant Journal

Abstract

Summary: The CRISPR/C as nuclease is becoming a major tool for targeted mutagenesis in eukaryotes by inducing double‐strand breaks (DSB s) at pre‐selected genomic sites that are repaired by non‐homologous end joining (NHEJ) in an error‐prone way. In plants, it could be demonstrated that the C as9 nuclease is able to induce heritable mutations in A rabidopsis thaliana and rice. Gene targeting (GT) by homologous recombination (HR) can also be induced by DSB s. Using a natural nuclease and marker genes, we previously developed an in planta GT strategy in which both a targeting vector and targeting locus are activated simultaneously via DSB induction during plant development. Here, we demonstrate that this strategy can be used for natural genes by CRISPR/C as‐mediated DSB induction. We were able to integrate a resistance cassette into the ADH 1 locus of A. thaliana via HR. Heritable events were identified using a PCR‐based genotyping approach, characterised by S outhern blotting and confirmed on the sequence level. A major concern is the specificity of the CRISPR/C as nucleases. Off‐target effects might be avoided using two adjacent sg RNA target sequences to guide the C as9 nickase to each of the two DNA strands, resulting in the formation of a DSB. By amplicon deep sequencing, we demonstrate that this C as9 paired nickase strategy has a mutagenic potential comparable with that of the nuclease, while the resulting mutations are mostly deletions. We also demonstrate the stable inheritance of such mutations in A. thaliana.

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.
