Coverages of TEs in galGal4 chromosomes with respect to the numbers of genes (a, b and c), CpG islands and S/MAR (d). Histograms in a and b show the coverages of TE copies annotated by REPET and those of the [TE + DM] annotation in each chromosome. The names of each of the 34 models are indicated in the left margin. The 3 bars near the abscissa describe data for the 34 TE models (all), those of the ISB annotations (ISB), and the proportions of the exonic, genic and intergenic regions in galGal4 (GG4). A grey background indicates one of the four TE types in galGal4: LINE, LTR, TIR and U (undetermined). The name is shown in the right margin. Histogram in b shows the proportions of TEs (percent coverage or number of copies). Background areas in green indicate TE data from the ISB annotation, light purple indicates the REPET (TE) annotations, and blue indicates the [TE + DM] annotations. The bar (GG4) near the abscissa shows the proportions of exons, introns and intergenes in galGal4. In a, b and c, the exons (non-coding and coding) are shown in red, genes are in yellow and the intergene regions are in green. A purple vertical bar indicates the size of the intergene regions in galGal4. The histogram in d represents the coverage/percentages of CpG islands, S/MAR elements and TEs inserted in CpG islands and S/MAR elements (blue), the 3-kbp distal and 3-kbp proximal ends of CpG islands and S/MAR elements (green) and in the rest of the chromosomes (purple)
