Correction to: Nature Communications https://doi.org/10.1038/s41467-017-02749-w, published online 22 January 2018

In the originally published HTML and PDF versions of this Article, gel images in Figs. 7c and 8c were not prepared as per the Nature journal policy. These figure panels have now been corrected in both the PDF and HTML versions of the Article.

In Fig. 7c, the lane labelled ‘Ha’ was inappropriately duplicated to represent the lane labelled ‘Ich13’. The corrected version of Fig. 7c includes PCR-RFLP on DNA from the Ichkeul 13 line, which had been run on a separate gel. The original unprocessed gel images are provided in Supplementary Figure 1 associated with this correction, with the relevant corresponding bands denoted. A repeat experiment of the PCR-RFLP test is also presented as Supplementary Figure 2.

In Fig. 8c, the image was assembled from two separate gels without clear demarcation. The corrected Fig. 8c clearly separates lanes from the two gels, and the original unprocessed gel images are provided in the Supplementary Information associated with this correction.

These corrections do not alter the original meaning of the experiments, their results, their interpretation, or the conclusions of the paper. We apologize for any confusion this may have caused to the readers of Nature Communications.
