Bi-directional Venn diagram. Bi-directional blast results are present in a Venn diagram. The code used for this diagram is: A oval = M. roreri genes; the B oval = M. perniciosa genes; C oval = L. bicolor genes; D oval = C. cinerea genes and E oval = U. maydis genes. Intersects are labeled with the corresponding letters and a number which represents the number of specific genes in that particular intersect. An E-value E-04 was used as the homology cut off.
