Statistics on the content of the eggNOG database

The eggNOG assignments for 1133 complete genomes were mapped onto the tree of life. The stacked bar charts outside the tree show the proportion of genes from each genome that can be assigned to a functionally annotated orthologous groups (green), to an unannotated orthologous groups (orange) or to no orthologous group (grey). The length of each bar is proportional to the number of genes in the respective genome. The pie charts inside the tree show the fraction of orthologous groups at each level in the hierarchy that have been annotated with a function description (green for non-supervised orthologous groups, light green for extended COGs and KOGs) or with a functional category.
