H3K27me3 marking of gene orthologs in relation to intra-chromosomal interactions in Ath. a Proportion of H3K27me3-marked genes overlapping with high connectivity regions as defined in Wang et al. [27] for synteny blocks enriched in genes with plastic or constrained H3K27me3 marking, or with no detectable enrichment. For each category of synteny blocks, the proportion of overlap is calculated separately for all the genes marked by H3K27me3 in Ath as well as for the genes with plastic or constrained H3K27me3 marking (see Methods). b Cumulative function distribution of the length of strong intra-chromosomal contacts involving synteny blocks either not enriched or else enriched in gene orthologs with either plastic or constrained H3K27me3 marking in the wild type
