Distribution of m1A, m5C, m6A and m7G peaks across mRNA segments. A The pie chart shows the percentage of m1A, m5C, m6A and m7G sites in each non-overlapping segment. B Distribution of m1A, m5C, m6A and m7G sites across mRNA segments. Each segment was normalized according to its average length in Ref-seq annotation. C Describing the corresponding proportions of m1A, m5C, m6A and m7G methylated peaks in each region of RNA, where orange indicates the normal oxygen group and purple indicates the hypoxia group
