Mammalian development begins in transcriptional silence followed by a period of widespread activation of thousands of genes. DNA methylation reprogramming is integral to embryogenesis and linked to Tet enzymes, but their function in early development is not well understood. Here, we generate combined deficiencies of all three Tet enzymes in mouse oocytes using a morpholino‐guided knockdown approach and study the impact of acute Tet enzyme deficiencies on preimplantation development. Tet1–3 deficient embryos arrest at the 2‐cell stage with the most severe phenotype linked to Tet2. Individual Tet enzymes display non‐redundant roles in the consecutive oxidation of 5‐methylcytosine to 5‐carboxylcytosine. Gene expression analysis uncovers that Tet enzymes are required for completion of embryonic genome activation (EGA) and fine‐tuned expression of transposable elements and chimeric transcripts. Whole‐genome bisulfite sequencing reveals minor changes of global DNA methylation in Tet‐deficient 2‐cell embryos, suggesting an important role of non‐catalytic functions of Tet enzymes in early embryogenesis. Our results demonstrate that Tet enzymes are key components of the clock that regulates the timing and extent of EGA in mammalian embryos. A morpholino‐based knockdown approach reveals an essential function of Tet enzymes in mouse preimplantation development and embryonic genome activation.
