Statistics on the numbers and lengths of transcripts, exons, and introns. The seven representative species are displayed in a phylogenetic order with unscaled branch length. (A) Histograms showing the distribution of the number of transcripts per gene, the number of exons per transcript, and the lengths of exons and introns. X-axis is the number or length, and Y-axis is the frequency, meaning how many elements have this number/length. The median lengths of exons and introns in each species are provided in the panel. (B) Barplots showing the proportions of total length of exons and introns. X-axis is the proportion. Bars show different species. The upper panel comes from all annotated transcripts. In the lower panel, only the transcript with the largest number of exons is selected for each gene
