File:GEvo-At-Al.png

GEvo analysis of syntenic regions from Arabidopsis thaliana and Arabidopsis lyrata. At1-Al1 and At2-At2 are derived from the speciation of the taxa. This is evidenced by the strong spatial syntenic signal as seen by the extensive collinear arrangement of orthologous gene pairs (pink and blue lines). These pairs of syntenic regions are also syntenic with respect to one another, and are derived from the most recent whole genome duplication event (WGD) shared by both taxa. This event is known as "alpha". Green lines connecting the out-paralogous gene pairs are shown between Al1 and At2. While also collinear, there is a lower density of syntenic gene pairs than between either At1-Al1 or At2-Al2. Al3 is also syntenic to these regions, but is derived from prior whole genome duplication event known as beta. Dark blue lines have been drawn connecting syntenic gene pairs between Al3 and Al2, and show the lowest density of all. Results can be regenerage at http://tinyurl.com/lvpzln .
