Correction to: Cell Research https://doi.org/10.1038/s41422-018-0022-x, published online 12 March 2018

In the ‘Supplementary information’ file, Figure S1b has been replaced by an updated figure. The labels of crRNA-DNMT-(+4) and crRNA-DNMT-23nt were placed in the wrong order, and the correct order should be “M, control, crRNA-DNMT-(-8), crRNA-DNMT-23nt, crRNA-DNMT-(+4) and crRNA-DNMT-(+8). The order of the crRNA names in the bottom illustrative figure was correct. The authors apologize for this carelessness.

We thank Dr. Panfeng Wu from Hubei University of Science and Technology for pointing out this mistake.

The original article has been corrected.
