Chocolate-peach syntenic dotplots
Whole genome comparison using Syntenic doplots between chocolate and peach with evolutionary distances of syntenic gene pairs show by color
The syntenic dotplot shown here is the same as that shown on this page, except this plot uses genes instead of the whole genomic sequence for its analysis. By having gene models, the evolutionary distance between sytnenic gene pairs may be calculated during a SynMap analysis. SynMap uses these values (Synonymous mutations) to generate a histogram, color codes the histogram, and uses those colors for the syntenic gene pair dots. This creates a syntenic dotplot with different colored "lines" showing syntenic regions of different ages. In this dotplot for grape and peach, you will see dark blue and light blue lines. The dark blue lines are for younger pairs of syntenic regions, and the light blue are for older pairs of syntenic regions. If you look carefully at this dotplot, you'll notice that for a given genomic region from either species, there is one dark blue syntenic line and two light blue syntenic lines in the dotplot. These are due to the shared history of these genomes. They shared a Paleohexaploidy event, and subsequently had a lineage divergence event. The dark blue lines are Orthologous regions derived from the divergence of these lineages, and the light blue lines are Out-paralogous regions derived from their ancient shared whole genome triplication event.
