Comparison of ChEP-P with other proteomic approaches. (A) Venn diagram illustrating the number of proteins identified by ChEP-P and the overlap with two published datasets aimed at identifying the RNA-binding proteome [38] and ubiquitinated proteins [2] in Arabidopsis seedlings. (B) Enrichment of chromatin-associated proteins by the various approaches. (C) Functional categories of chromatin related-proteins obtained in the ChEP-P experiment. (D) Gene ontology (biological process) analysis of the nucleus-localized proteins identified by ChEP-P. The GO figure was generated using REVIGO with the R script from the REVIGO web-server. The gradient colour corresponds to the significance (log10 P value), the size of the plotted bubbles indicates the frequency of the GO terms they represent
