Figure 5

Bar plots illustrating the breakdown of terminal GOs in the seven taxonomic groups for level 1 GO terms. A total of 1,871 out of 1,924 GOs (97.24%) could be reliably mapped to their parents. Level 1 GOs that could not be mapped include “D-alanyl carrier activity [GO:0036370],” “electron carrier activity [GO:0009055],” “chemoattractant activity [GO:0042056],” “chemorepellent activity [GO:0045499],” and “nutrient reservoir activity [GO:0045735].” Note that terminal GOs may have more than one parent. The Venn diagram shows that none of the A, B, AB, and AE taxonomic groups uniquely code for any level 1 GO term.
