Figure 2

Overlap among gene families for four smut fungi species. This is the venn diagram used to compare the gene families of four smut fungi, four colors (green, red, yellow and blue) mean four gene family sets, and the overlap parts have the overlapping color. Numbers indicate the gene families in each comparison. S means the gene families specific to S. scitamineum, S-U means common gene families of S. scitamineum and U. hordei, S-U-R means common gene families of S. scitamineum, U. hordei and S. reilianum, S-U-R-M means common gene families of four smut fungi.
