Figure 4

Annotation of inversion 2s distal and proximal breakpoint regions in D. virilis (non-inverted chromosome) and D. mojavensis (inverted chromosome). Genes are depicted as solid boxes (exons) linked by polygonal lines (introns) with the 5' and 3' ends showing the direction of transcription. Genes adjacent to the distal (AB) and proximal (CD) breakpoints of D. virilis are colored in green and blue, respectively. Orthologs in the distal (AC) and proximal (BD) D. mojavensis breakpoint regions are colored accordingly. Red curly brackets with an arrow indicate the breakpoint junctions. TE insertions are shown as solid rectangles: blue (Bu T5), purple (Homo 3) or yellow (Galileo). Some TE insertions are flanked by TSDs insertions depicted in boxes above (or below) them. Dotted sections are not drawn to scale.
