The landscape of accessible chromatin in bovine oocytes and early embryos

ATAC sequencing of bovine oocytes and early embryos revealed a genome-wide map of accessible chromatin of bovine early embryo development, highlighting the critical features of chromatin landscape and epigenetic reprogramming during bovine preimplantation embryo development. GV, MII oocytes and differental developmental stages embryos (2-, 4-, 8-, 16-cell, morula, blastocyst, day 14 elongating embryo) were pooled for ATAC sequencing analysis. **Please note that Peaks in individual samples from the same development stage were merged and the resulting peak data is linked to the corresponding first *A sample records.
