library_construction_protocol: For mammal and E. coli genomic DNA extraction, cells were lysed by 0.5% SDS and digested with 0.1mg/mL proteinase K (TransGen Biotech#: GE201-01) at 37°C in a shake with 220 rpm for 4-6 hours followed by phenol-chloroform nucleic acid extraction method. For Arabidopsis and rice gDNA extraction, seedlings were grounded in liquid nitrogen and then lysed by 0.5% SDS and digested with 0.1 mg/mL proteinase K (TransGen Biotech#: GE201-01) at 37°C in a shake with 220 rpm for 4-6 hours followed by phenol-chloroform nucleic acid extraction method. For yeast gDNA extraction, cells were resuspended in TE buffer with 0.5% NP40 and equal volume glass beads (Sigma#: G8772), and beat 6 times in 30 sec at 60 Hz with 1 min pausing at 4°C to destroy cell walls. Then cells were collected, lysed by 0.5% SDS and digested with 0.1mg/mL proteinase K at 37°C in a shake with 220 rpm for 4-6 hours followed by phenol-chloroform nucleic acid extraction method. For cDNA hybrids synthesis, total RNA was extracted according to the manual of TRIzol™ (ThermoFisher Scientific#:15596026) from the manufacturer. DNase I (ThermoFisher Scientific#: EN0521) treatment was performed at 37°C to remove potential gDNA contamination. cDNA hybrids were synthesized by ProtoScript® II Reverse Transcriptase with d(T)23VN primer according to the manufacturer'
