Site-directed nucleases: a paradigm shift in predictable, knowledge-based plant breeding

Podevin, Nancy, Davies, Howard V., Hartung, Frank, Nogué, Fabien, Casacuberta, Josep M.·2013·Trends in biotechnology

Abstract

Conventional plant breeding exploits existing genetic variability and introduces new variability by mutagenesis. This has proven highly successful in securing food supplies for an ever-growing human population. The use of genetically modified plants is a complementary approach but all plant breeding techniques have limitations. Here, we discuss how the recent evolution of targeted mutagenesis and DNA insertion techniques based on tailor-made site-directed nucleases (SDNs) provides opportunities to overcome such limitations. Plant breeding companies are exploiting SDNs to develop a new generation of crops with new and improved traits. Nevertheless, some technical limitations as well as significant uncertainties on the regulatory status of SDNs may challenge their use for commercial plant breeding.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • SDN3 mutants use a repair template with homologous regions of at least 500 base pairs flanking the DSB, enabling the insertion of new sequences, similar to transgenic or cisgenic approaches.

    “SDN3 mutants use a repair template with homologous regions of at least 500 base pairs flanking the DSB, enabling the insertion of new sequences, similar to transgenic or cisgenic approaches.”
  • SDN3 applications in plants face challenges due to the low efficiency of homologous recombination, making them complex and less efficient.

    “Nonetheless, SDN3 applications in plants face challenges due to the low efficiency of homologous recombination (HDR), making them complex and less efficient (Verma et al., 2020; Podevin et al., 2013; Van de Wiel et al., 2017).”

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.
