Correction to: Nature https://doi.org/10.1038/s41586-019-1509-4, published online 28 August 2019.
In Figs. 1c and 3a of this Letter, the genotype should have read ‘Pdpy-7::LifeAct::GFP’ instead of ‘Ppdy-7::LifeAct::GFP’. In addition, the black box in Extended Data Fig. 1d should have shown the text ‘spc-1(RNAi) pix-1(gk416)’. These errors have been corrected online.
