Distant transcription initiation in locusts and fruit flies. a The density distribution of distances from the annotated start codon of protein-coding genes to its farthest upstream core promoters. b Boxplot showing the length difference of the mRNA leaders (5′-UTRs) with different intron numbers. c Boxplot showing the exon length difference in the mRNA leaders with different intron numbers. The red asterisk indicates P < 2.2e−16 according to the Wilcoxon rank-sum test. N.S., not significant. d Standard deviation of exon lengths in the mRNA leaders with different intron numbers. The red asterisk indicates P < 2.2e−16 according to the Wilcoxon rank-sum test. N.S., not significant
