Distributions of R-loop characteristics in different datasets. A Size and B genomic distribution of R-loops. An R-loop is considered to be from a given genomic region when it overlaps more than one base with that region. In the case where an R-loop overlaps with more than one genomic region, we assigned it according to the priority (promoter2k > terminator2k > exon > intron > intergenic). Promoter2k: within 2000 nt upstream of a gene; terminator2k: within 2000 nt downstream of a gene; intergenic: regions excluding genes, promoter2ks, and terminator2ks. C Venn diagram analysis for R-loops, transcribed regions, and genes at base level. R-loops and transcribed regions were defined by DRIP-seq (red) and GRO-seq (green), respectively. Gene regions (gray) were extracted based on gene annotations (see “Methods” for details). Areas marked with dashed lines indicate the overlap of R-loops and transcribed regions. The percentages represent the percentage of R-loops that are derived from the transcribed regions. M: million bases
