Homology-Integrated CRISPR–Cas (HI-CRISPR) System for One-Step Multigene Disruption in Saccharomyces cerevisiae

Abstract

One-step multiple gene disruption in the model organism Saccharomyces cerevisiae is a highly useful tool for both basic and applied research, but it remains a challenge. Here, we report a rapid, efficient, and potentially scalable strategy based on the type II Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR associated proteins (Cas) system to generate multiple gene disruptions simultaneously in S. cerevisiae. A 100 bp dsDNA mutagenizing homologous recombination donor is inserted between two direct repeats for each target gene in a CRISPR array consisting of multiple donor and guide sequence pairs. An ultrahigh copy number plasmid carrying iCas9, a variant of wild-type Cas9, trans-encoded RNA (tracrRNA), and a homology-integrated crRNA cassette is designed to greatly increase the gene disruption efficiency. As proof of concept, three genes, CAN1, ADE2, and LYP1, were simultaneously disrupted in 4 days with an efficiency ranging from 27 to 87%. Another three genes involved in an artificial hydrocortisone biosynthetic pathway, ATF2, GCY1, and YPR1, were simultaneously disrupted in 6 days with 100% efficiency. This homology-integrated CRISPR (HI-CRISPR) strategy represents a powerful tool for creating yeast strains with multiple gene knockouts.

  • Bao et al.'s HI-CRISPR system utilized a recyclable plasmid, so that the plasmid can be reused to generate further multiple knockouts in the same strain.

    “Furthermore, their new multigene disruption HI-CRISPR system utilized a recyclable plasmid, so that the plasmid can be reused to generate further multiple knockouts in the same strain (Bao et al. 2015).”

  • Bao et al. (2015) used the CRISPR-Cas9 system to generate multiple gene disruptions in a single step in S. cerevisiae, representing a powerful tool for creating yeast strains with multiple knockouts in less than a week, termed the HI-CRISPR system.

    “Bao et al. (2015) on the other hand have used the CRISPR-Cas9 system to generate multiple gene disruptions in a single step in S. cerevisiae representing a powerful tool for creating yeast strains with multiple knockouts in less than a week, and they have termed this the HI-CRISPR system.”

  • Bao et al. (2015) found that triple gene disruptions were also affected by the CRISPR-Cas9 array used.

    “In addition, Bao et al. (2015) found that triple gene disruptions were also affected by the CRISPR-Cas9 array (the genome sequence encoding the gRNA strand that directs the degradation/modification of the gene of interest) used; however, this should be addressable in the near future as rules for choosing efficient CRISPR-Cas9 targeting sites emerge with greater understanding of the CRISPR-Cas9”

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.
