Plot of splice site scores of introns identified in Phytophthora sojae. The scores of 5' splice sites and branch sites are compared to those of a reference set of U12 introns as used by Burge et al  (within blue rectangle). Introns in P. sojae predicted to be of the U12 type have both 5' splice site and branch site scores equal to or larger than the minimum values of the reference set. Arrows indicate one GT-AG and two AT-AC introns.
