Selected gene structure property correlations in all sets. a) Exon GC vs. count: Logarithmic display of median exon GC content [%] vs. exon count per transcript. b) Exon length vs. count: Semi-logarithmic display of median exon length [bp] vs. exon count per transcript. c) Intron GC vs. count Logarithmic display of median intron GC content [%] vs. intron count per transcript per transcript. d) Intron length vs. count: Semi-logarithmic display of median intron length [bp] vs. intron count per transcript. Facet columns show the two automatically generated sets (AUTO & AUTO-SUB; left) and three OGS-based sets (OGS & MAN-SUB & MAN-ADD; right). Values are given for the longest transcript per gene. Spearman’s rank correlation coefficients (r) of each property combination are given above each pair of plots (AUTO: orange, AUTO-SUB: red, MAN-ADD: dark green, MAN-SUB: dark blue, OGS: light blue). Facet rows show the seven species (Anoplophora glabripennis [Coleoptera], Athalia rosae [Hymenoptera], Frankliniella occidentalis [Thysanoptera], Leptinotarsa decemlineata [Coleoptera], Oncopeltus fasciatus [Hemiptera], Orussus abietinus [Hymenoptera]) with color coding according to Fig. 1
