Fig. 3

a Multi-dimensional display of genomic components of the noble rhubarb genome. The density was calculated per 100 Kb. b Frequency distributions of synonymous substitution rates (Ks) between homologous gene pairs in syntenic blocks of R. nobile-R. nobile, F. tataricum-F. tataricum and R. nobile-F. tataricum. Both species are members of the family Polygonaceae. c Number of significantly expanded (+) and contracted (-) gene families in nine Caryophyllales species with high-quality genome sequences available. d REVIGO clusters of overrepresented GO terms for significantly expanded gene families in the noble rhubarb genome. Each bubble represents a summarized GO term from the full GO list by reducing functional redundancies, and their closeness on the plot reflects their closeness in the GO graph, i.e. the semantic similarity. e KEGG enrichment of metabolic genes that were significantly expanded in the noble rhubarb genome.
