Distribution of gene structural features across six species. Subpanels (a–d) show comparative analyses of (a) gene length, (b) CDS length, (c) exon length, and (d) intron length between Xingan mandarin (Citrus reticulata ‘Xingan’) and five other species: Arabidopsis thaliana, C. grandis, C. reticulata ‘Mangshan’, C. sinensis, and C. reticulata cv. Ponkan.
