Figure 1From: Genome-wide determination of poly(A) sites in Medicago truncatula: evolutionary conservation of alternative poly(A) site choiceDistances of intergenic PACs from neighboring genes. M. truncatula genes were extended at their 3′ ends as described in Methods, and the distances between the ends of the extended genes and intergenic PACs (those that fall between extended annotations) were plotted. The cumulative sum of all intergenic PACs is plotted on the y-axis. Note the non-canonical scale for the x-axis.Back to article page
