Heterochromatin fragmentation in pol2a-12. a DAPI-stained nuclei extracted from WT and pol2a-12 plants. Scale bar: 5 μm. b Number of chromocenter per nucleus (left), area of individual chromocenter normalized to the entire nucleus area (middle) and relative heterochromatic fraction (right) in WT and pol2a-12 quantified on 56 and 59 DAPI-stained nuclei, respectively. P-values from an unpaired two-sided Student’s t-test are indicated. c Metaplots showing H2A.W enrichment (log2 signal over input) in L5 and pol2a-12 at H2A.W peaks (top) and at peaks overlapping TEs upregulated in pol2a-12 (bottom). Shaded areas show standard deviation. TE annotations were extended 1 kb upstream
