Venn diagram showing overlap of up-regulated and down-regulated genes of Tibetan hulless barley in response to powdery mildew. (A) Venn diagram showing overlap of up-regulated genes of G7 in response to powdery mildew. (B) Down-regulated genes of G7 in response to powdery mildew. (C) Venn diagram of the up-regulated genes of G7 and Z13 in response to powdery mildew. (D) Venn diagram of the down-regulated genes of G7 and Z13 in response to powdery mildew. (E) Venn diagram depicting intersections of up-regulated genes of Z13 in response to powdery mildew. (F) Down-regulated genes of Z13 in response to powdery mildew. Area of overlap is not proportional to the degree of overlap. The numbers of genes and their percentage in each region of the diagram are indicated.
