library_construction_protocol: Total DNA was extracted from cells using Phenol-chloroform DNA extraction protocol. Briefly, 200-1000 ng genomic DNA was used for WGBS library construction. DNA was sonicated to ~250 bp fragments with the Diagenode Bioruptor Pico. Then DNA was subjected to end-repair, A-tailing, and ligation using VAHTS Universal DNA Library Prep Kit for Illumina V3 (Vazyme, ND607) and methylated adaptor (Roche) according to the manufacturer's instructions. DNA was purified with VAHTS DNA Clean Beads. Subsequently, library was bisulfite modified using QIAGEN EpiTect Fast DNA Bisulfite Kit (59824) and amplified with KAPA2G Robust HotStart PCR Kits with dNTPs (Sigma-Aldrich). Library was finally subjected to 150 bp paired-end sequencing using the Illumina Novaseq6000 instrument.
