FIE - HA + H3K27me3 genes are enriched for genes under PcG repression in vegetative tissues. (a) Numbers of genes up- and down-regulated in clf-7 swn-28 and siFIE seedlings compared to wildtype. Overlap of Venn diagram indicates the numbers of genes common to both datasets. (b) Numbers of genes up-regulated in clf-7 swn-28, siFIE or both that are also associated with a FIE-HA+H3K27me3 or H3K27me3 only ChIP-seq peak. Percentages are the percentage of genes associated with a ChIP-seq peak that are also in the up-regulated gene lists.
