Graphical representation of unique genomic regions. (a) The graphical display for the unique regions within a genome depicts the full-length sequences, without common introns, as white rectangles with the unique regions in red for genes (top) and blue for individual transcripts (bottom). Repeats or low complexity regions are highlighted in black and those redundant in grey. (b) For the unique regions shared across genomes, the two levels of the display correspond to all the unique regions of the gene in the reference organism and those matched by the target organism. The colour-coded scheme for the reference is the same as in (a). For the target, the shared unique positions are placed relative to those matched with the reference and the colours represent all the possible combinations that can be found between the shared sequences, as explained in the main text.
