Characteristics of the OrthoDB v10 taxonomic space for each species we tested
| Number of species in the same taxonomic unit | Genus | Family | Order | Class | Phylum | Kingdom | OrthoDB root used for tests | Number of proteins in the root |
|---|---|---|---|---|---|---|---|---|
| N. crassa | 0 | 1 | 7 | 96 | 364 | 548 | Fungi | 5 850 648 |
| C. elegans | 2 | 2 | 4 | 5 | 6 | 447 | Metazoa | 8 266 016 |
| A.thaliana | 1 | 7 | 9 | – | 99 | 116 | Plantae | 3 510 742 |
| D. melanogaster a | 19 | 19 | 55 | 147 | 169 | 447 | Metazoa | 8 266 016 |
| S. lycopersicum | 1 | 9 | 10 | – | 99 | 116 | Plantae | 3 510 742 |
| D. rerio a | 0 | 4 | 4 | 49 | 245 | 447 | Metazoa | 8 266 016 |
The number of species is naturally the largest in the kingdom section of the database.
aFor tests in the genus-, family- and order-excluded modes for D. melanogaster and D. rerio, the phylum set was used as the largest set of reference proteins.
