Gene Ontology analysis of genes in the FIE - HA + H3K27me3 and H3K27me3 only datasets. GO analysis was carried out using BinGO . Enriched categories for biological process, molecular function and cellular component are shown. GOslim categories with significant enrichment in the dataset were highlighted in colour with different colours representing different levels of significance. The orange categories are most significantly overrepresented. White nodes are not significantly overrepresented. The area of a node is proportional to the number of genes in the corresponding GO category.
