    Mutagenesis of the infectious clone of TBEV. The plasmid pGGVs 660–1982 H [29] that contains the partial PrM-E gene fragment between nucleotides 660–1882 of the Vs virus genome was used as a template in PCR to synthesize megaprimers E-1171 A/G (genome positions and lengths are specified). Primers used to produce megaprimers, with targeted mutations (circles) are represented by thick arrows. Subsequently the megaprimer without the other pair of primers was used to amplify plasmid pGGVs 660–1982 H (solid circular line). The produced linear newly-synthesized complementary ssDNA molecules (nicked circular dotted line) with acquired mutations were annealed during the last step of PCR, randomly producing twice-nic ked circular DNA. Parent Dam+ methylated DNA of the pGGVs 660–1982 H was removed by DpnI endonuclease digestion to facilitate clone selection.

    The DAM identification (DamID) procedure in C. elegans . ( A ) How DamID works. A fusion protein consisting of DNA adenine methyltransferase (DAM) and the protein of interest methylates GATC sites near binding sites. Genomic DNA is digested with Dpn I, which cuts only methylated GATC sites. Adaptors are added, and DNA is digested with Dpn II (which cuts at unmethylated GATC sites) to assure selective amplification of methylated DNA. A parallel DAM-only experiment is also performed to control for non-specific methylation. Samples are then labeled and hybridized to arrays. ( B ) Schematic of plasmid constructs used for preparation of transgenic strains. ( C , D ) Transgene expression. Nuclear localization of GFP was detected in UL1782 animals (expressing DAM∷DAF-16∷GFP) (marked with arrows in C) in body wall muscle and anterior bulb of pharynx (circled) following heat shock. UL1787 animals (expressing DAM∷GFP) (D) do not show nuclear localization. ( E ) DAF-16∷DAM methylation profile for ist-1 , one of several evolutionarily conserved FoxO targets identified. ( F ) Average distribution of methylation (DAF-16∷DAM versus DAM) from peak center for 1135 peaks identified.

    Detection of 6mA by DA-6mA-seq. ( a ) Flowchart of DA-6mA-seq. DpnI cleaves fully methylated G(6mA)TC sites, whereas the cleavage of DpnII is hindered by hemi- or fully-methylated 6mA. After treatment with restriction enzyme, DNA segments are further sheared by sonication to ∼300 bp followed by standard Illumina DNA library construction procedures. ( b ) DA-6mA-seq identifies consistent 6mA sites as reported previously 8 . ( c ) The genomic distribution of 6mA sites in promoter, genic and intergenic regions. Promoter is defined as −1,000 to +1,000 bp region around transcription start sites (TSS). ( d ) The periodic distribution pattern of base-resolution 6mA sites identified by DA-6mA-seq around TSS.
