Definition, identification and characterization of mUTRs. (A) The schematic shows two prototype genes (ORF1 and ORF2 shown in blue, UTRs shown in green) encoding transcript isoforms with extended 5′-meiotic UTRs (5′-mUTRs) or 3′-meiotic UTRs (3′-mUTRs), respectively (shown in red). (B) A flow chart depicts the key steps of the mUTR annotation procedure and its output. (C) UTR length distribution in mitosis and meiosis. A box plot shows the size distribution in log-transformed lengths (in bp; y-axis) for 5′-UTRs and 3′-UTRs during meiosis and mitosis (x-axis). The red line is the median.
