Differential accumulation of H3K9me2 signal between H. schachtii-infected and noninfected Col-0 plants. A and B, Distribution of H3K9me2 peaks overlapping with protein-coding genes, miRNAs, and TEs, and enriched (A) or depleted (B) in H. schachtii-infected Col-0 as compared with noninfected control plants. C and D, Heatmaps of ChIP-seq signals enriched (C) or depleted (D) in protein-coding genes in H. schachtii-infected Col-0 versus noninfected plants. Genes were scaled to the same size with TSS flanked by 2-kb regions. Only significant (P-value < 0.05, log2FC > 1) H3K9me2 peaks were included in the analysis. Color scales on the right indicate H3K9me2 signal intensity, which reflects normalized sequence reads. E and F, Representative examples of H3K9me2 peaks overlapping with protein-coding genes that are enriched (E) or depleted (F) in H. schachtii-infected Col-0 versus noninfected plants.
