The proportions of protein-kinase families in O. tauri , A. thaliana , S. cerevisiae , and H. sapiens . (A) A Venn diagram summarising overall genome similarity in the four species, measured by the inter-species overlap of ortholog-groups predicted by OrthoMCL [33]. Percentages indicate the proportion of the proteome annotated by ortholog-groups that are unique to the organism within this comparison. (B) The proportion of each genome that encodes catalytic protein kinases; the adjacent bar charts show the proportion of super-families within this subset. (C) The proportions of the genome occupied by each protein kinase family. The families included are those present in O. tauri, in addition to TK. “Other kinases”, which are not included in this chart – because they are not present across the eukaryotes studied – amount to 2.5% in O. tauri, 59.9% in A. thaliana, 9.9% in H. sapiens, and 27% in S. cerevisiae. The large number of “Other kinases” in A. thaliana is due to the many RLKs [34], which are absent in O. tauri.
